Nothing else to do so I did some internet research on aftermarket wheels. I had the Carrozzeria V-Track wheels on my 2006 ZX-14 and they made a noticeable difference in turn in. These wheels are now available through Rotobox the company that took over Carrozzeria. Rotobox offers the Carrozzeria V-Track and their own Apex-6 wheel which is mfg. in the USA. The Apex-6 is a newer design and lighter. It is difficult to compare weights as they are not always apples to apples. I looked at both wheels from Rotobox and one wheel from BST comparing weights & pricing.

I found stock ZX-14 wheel weight listed on the Rotobox website as 31.24# per set. I am assuming this is without discs & sprocket and don't know if it is for the later ZX14R 2012 + model.

Carrozzeria V-Track front 17 X 3.5 is 8.3# fully assembled (brgs. & disc carriers)
Carrezzeria V-Track Rear `7 X 6 is 13.9# fully assembled (brgs. disc carrier & sprocket carrier)
Carrezzeria V-Track wheel set is 22.2# fully assembled. Cost from $2,149 from Core Performance

Rotobox Apex-6 front 17 X 3.5 is 7.51# fully assembled (brgs. & disc carriers)
Rotobox Apex-6 rear 17 X 6 is 11.21# fully assembled (brgs. disc carrier & sprocket carrier)
Rotobox Apex-6 wheel set is 18.72# fully assembled. Cost is $2,299.
The Apex-6's are 3.48# lighter than the V-track wheels per set and cost $150 more.

Both the Carrezzeria and Apex-6 wheels use stock Kawasaki brake discs and sprockets.

BST front 17 X 3.5 is 6.65# with brgs.
BST rear 17 X 6 is 7.2 # with brgs.
BST wheel set is 13.75# with brgs. The best price I found for the set of BST wheels was $3,040 plus frt.

The BST wheels are 4.97# lighter per set than the Apex-6's and cost $841 per set more. That's $169.21/pound. That's assuming the BST wheels include everything the Rotobox Apex-6's do. This is not a statement of value it is just pricing per pound difference.

The BST wheels require non OEM sprockets and possibly brake discs which will increase costs from what I found??

Weights & prices listed are with steel brgs. Price add for ceramic bearings varies widely with supplier.

Feel free to weigh in if you find better pricing or different weight information.

These wheels are now available through Rotobox the company that took over Carrozzeria.

The weight of a rear BST rim is a lot less than a rear Carrozzeria. There is not so much difference with the front. I have discontinued Tri-R wheels by Carrozerria. I've been thinking over BST rims for my busa for the last 5 or six years. They are more expensive/weight loss. I have the money, I'm just waiting for inspiration to pay out. For a large bike like the 14, the weight reduction of CF over forged aluminum might not be that noticeable but I have to know for myself.

One think you might want to consider is the fragility of CF. It is super strong but it's extremely rigid. If it deforms, it shatters. If you like wheelies and low tire pressures, that might not be for you unless you have very smooth roads. Turbo could be another factor.

If you go with BSTs, think about what width you want. Wide is for drag racing, narrow is for canyon riding. Narrow is obviously lighter.

I've decided on the BST Rapid TEKs with a 6" wide rear for my busa. No heavy duty reinforcement.

Consider where you will get your tires changed. I wouldn't let a shop do BSTs unless they let me watch. I was planning to use one of the top of the line Cycle Hill tire changers to do my own tires. No way would I use tire irons on CF.

Having aftermarket rotors and sprockets is a big plus. I would do that even if I had stock rims. Don't let that scare you off, you should be buying that stuff anyway if you are concerned about weight loss.

Rather than quibble over price/weight loss, I'd rather have the best if I'm going to spend a pile of money on wheels. The only consideration is durability. If you're going to bust your new rims and wreck the bike riding the way you like to ride, what's the use with CF? I plan to keep my stock rims equipped for early in the season and then switch to the BSTs when I am familiar with the conditions of the road. If I feel the need for a few wheelies in summer, I'll have to switch back to OEM. I guess I'll just have to see how that goes.

Rook we think are a lot alike in this. I was happy with the Correzzeria wheels years ago but I will be moving on if and when I decide to replace the wheels on my 14R. I don't intentionally do wheelies but with a ZX14R they do happen. At my age I ride much more carefully (fast but not reckless) than I used to. I have considered the tire changing situation with CF wheels and there is only one shop and one mechanic there in Louisville I would use for these or forged aluminum wheels. I will be using stock wheel sizes and road rubber, not drag race tires. The roads here are pretty good year round so I am not concerned with that. It is not a matter of money for me with the wheels but what is best for my application. I admire how much weight you have been able to remove from the 14 but I will only go after the big stuff. So far that includes the complete exhaust system, the battery, front fender, gas cap, rear sprocket, side stand, mirrors and a few other misc. items. I doubt in the end, as much as I like the CF wheels, I will go that way. I will continue to research the options this winter but in the end will probably go with the best and lightest forged aluminum wheels I can find.

Rook you are right, Core Moto took over Carrozzeria in 2016. There is a new BST CF wheel available for the
ZX14/14R that I have not been able to find out much about. It is a 5 split spoke design they are calling Rapid TEK. The only price I found was $3,690.00 a set and they appear to be heavier than the older 5 spoke design. Beautiful wheels, take a look if you have not already seen them.

Yep, Rapid TEK with 6" width rear. That's the one I like for the Gen2 Hayabusa. The front is a half pound heavier than the standard BST Diamond TEK wheel. It's static weight spec (basically how much weight it can safely support) is 340 v 330 with the standard design. Not much of an improvement but it offsets the disadvantage of additional weight a bit in my view.

The 6" rear Rapid TEK is what got me. It's over 1 lb lighter than the standard 6" Diamond TEK wheel. The Rapid TEK rear has a static load rating of 615 lbs v 550 lbs with the 6" Diamond TEK. The static load rating of the 6" Rapid TEK equals the static load rating of the heavy duty reinforced rear 6.625" Diamond TEK R+ which is about 3lb, 10 oz heavier than the Rapid TEK rear!

Sucks they had to make the front Rapid TEK so heavy while only gaining a small improvement in load bearing capability. I don't know what went on there. For the average rider the front is more important than the rear because that's the one that has to take the hit coming down from a wheelie.

The strongest front would be a 16" diameter Diamond TEK R+ with a static load rating of 770 lbs. It's a lb and a half heavier than a standard Diamond TEK though. With bearings and hardware, it's a half lb heavier than my forged aluminum Carrazzeria Tri-R front with bearings and hardware. For utilitarian purposes, you might as well go with the added safety of an aluminum wheel. Not only that, with the Diamond TEK 16" rim, you'd need to find 16" front tires and that would reduce your front ground clearance by a half inch too.

The new 7 TEKS have high static load rating. The 17" 7 TEK front is a little heavier than my Carrazzeria front. The Rapid TEK front is almost a pound lighter than my Carrozzeria. The 6" wide 7 TEK rear is about 2 and a half pounds lighter than my Carrozzeria. The Rapid TEK rear is almost 3 and a half pounds lighter than my Carrozzeria.

The all around lightest setup would be a standard Diamond TEK front and a Rapid TEK rear. The strongest would be a set of 7 TEKS but they are heavy, the front being as heavy as an aluminum wheel.

My conclusion is the Rapid TEKS are the best compromise for those of us who couldn't live with a set of mix and match wheels. Just watch the wheelies. This is all Hayabusa related info but it probably is in the ballpark for the ZX-14 as well.

Superbike Unlimited claims 9.60 lbs for a ZX-14 Rapid TEK rear with carriers, hardware and bearings. Brock claims the same for the 6" Diamond TEK.

Superbike Unlimited claims 6.55 lb for front with bearings. Brocks claims 6.05 lb for front Diamond TEK with bearings. Just like the busa. The front is a half pound heavier if you go with Rapid TEKS. Compare the weight difference and static load spec of the rears. Overall you're lighter with the Rapid TEKs, the front is a little stronger and the rear is a lot stronger. The front Rapid TEK is still a lot lighter than an aluminum wheel. ...or put a Diamond TEK on the front and a Rapid TEK on the rear. I couldn't do that but it would still look a lot better than any set of RotoBox wheels.

I agree Rook. Are these the BST's you want for the Suzuki? Best looking wheel on the market.

* Last updated by: jstewart on 11/16/2020 @ 7:03 AM *

Rook made up my mind fast. Bought a set of the BST Rapid TEK's today. After talking to old friend and source at Brock's I am not worrying about wheel damage from wheelies with these wheels (which I try to avoid anyway). Should have these by Friday. I sent you a PM.

The only reason I might go with anything else would be for Turbo and even then, I think Rapid TEKs are a decent choice.

Yep, I'm going with Rapid TEKS on the busa. I really think the OEM busa wheel looks great but they are so heavy. The rapid TEKS will look cool and drop a lot of weight.

Thanks for the info on wheelies. I guess we'd be hearing about CF wheel falure all the time if it was a real concern. I will be a little careful with mine when I get them though.

If you have a fish scale, hang each wheel on there to check the weight for us.

Will do, no fish scale but a electronic scale that measures down to one ounce. I guess I need to call Brock's back tomorrow about disc brake suppliers for these wheels. No problem finding a good light rear sprocket but I am having a problem identifying brake discs that fit the BST wheel. If you have already done this research and decided on a brake disc supplier let me know which ones you like for the Rapid TEK's.

I was going to go with Talon for mine. Vortex is the lightest sprocket I have used but I think Talon will be lighter. There might be one other one that was lighter than Vortex but it must be pretty obscure. I think there's about 5 sprockets that definitely look light weight for the 14 and I have use 3 so far. It only comes in gold but it's a nice transparent anodized gold.

https://www.bikehps.com/acatalog/Talon_Sprockets_for_BST_Wheels.html

I know of nothing other than a Galfer rear wave rotor. It's 13.2 oz lighter than the stock Gen1 rear rotor not including bolts which I would suggest Pro-Bolt Ti or any Ti. It really bugs me that Pro-Bolt has stopped their loyalty points and on top of that they no longer list the weight of their products. The finish on the Ti is raher faint too---I suppose so it looks less like anodized aluminum but if I order a black bolt for $30, I want it black, not grey. I'm looking into other light weight bolt suppliers.

As far as front rotors I would have to check the busa sight for the weight of Galfers. It looks like they do fit a front BST, it would just be a matter of finding which OEM bolt pattern matches the BST bolt pattern. I think it may be Suzuki. I like the Galfer Superbike rotors but i would have to find out if they work well on the street. They are recommended for track only. They look a bit heavier than he standards too. The standard Galfer rotors look fine too. I'd really like to know the weight before buying though.

My CZ rotors are about 10mm larger in diameter and they are each only about 4 oz lighter than a stock rotor (that had some wear). It seems doubtful you will get lighter than stock rotors but something is telling me the Galfers were lighter than than stock busa rotors.

I got some incorrect information from one BST supplier and thus my posting the stock OEM ZX14 rotors would not fit the BST Rapid TEK wheels. As Usual Brock came through for me with correct info. Figures as he is the US distributor for these wheels. The stock OEM brake rotors will fit these wheels (front & rear). I also found one correct aftermarket quality supplier through Schnitz Racing. Braking (Italian company) makes direct replacement rotors. I found them before finding the stock OEM rotors would work. The Braking superbike rotors are stainless steel with alloy carriers. Of course any aftermarket rotor listed for replacement of the OEM rotors will work.
These are apparently Schnitz part numbers:
Front right rotor- # 1710-1429-$274.95
Left front rotor-# 1710-1428-$274.95
Rear rotor-#1710-0407-$149.95
Schnitz did not have the weights for these rotors, apparently nobody else asks. For now I am going to stick with the stock rotors. They are more than adequate for me as far as stopping power. I will wait for Rook to find the lightest rotors available and reconsider.
The wheels are supposed to arrive here today. I will weigh them for comparison to the listed weight on Brock's site and post weights here tonight. When I remove the stock 2012 wheels I will weigh them as well and post the weights.

Awesome. I'd be curious to know the weight of BST rims. I have weights for Hayabusa BSTs. Whoever posted the pics didn't seem to be unhappy with the results.

I will wait for Rook to find the lightest rotors available and reconsider.

I hate to say it but the Yanna Shiki rotors look so cool I'm tempted to try them out. I guess the main thing is that the rotors you get work well. The CZ rotors I bought look great and they are light but they groan when I brake hard. Never had a problem but I think because they are so thin, they may vibrate. I've heard that full floating rotors can be noisy too but it's normal.

I might just go for Yanna Shiki rotors. Sure I'd pay a couple hundred more if I knew something else was lighter ad worked well but these look pretty light and I love that cool pattern on the surface. Roadtoad and Micheal Parris Hueberger give very reliable advice. I might just grab a set of Yana Shikis. Roadtoad was on here for a short while BTW. He switched over to a 14R but keeping off the forums. I hope he comes back soon.

Rook these are the BST Rapid TEK weights on my digital scale. Weights are with ceramic bearings, valves, spacers, rubber/steel sprocket dampers in the rear wheel, sprocket adapters. Everything but rear sprocket, brake rotors, mounting hardware.
Front 3.5 X 17--6 pounds 8.5 ounces
rear 6.0 X 17--7 pounds 9.5 ounces
Not bad to say the least.

Not bad at all! The rear is 2 and a half pounds lighter than Brocks reports. Please give us a little review after you have a chance to test them. I will probably be testing mine next June.

Rook no way my scale can be off 2 pounds. These were the weights of the wheels out of the box as they arrived. This does not include the axles, or any hardware on the bike that is reused to mount the wheels. I need to call Brock's tomorrow about another part and I will ask them about the weight discrepancy in weight of the rear wheel. I talked to my guy here about mounting tires and the only problem is they will not remount my tires which only have several hundred miles on them. This is a Ducati dealer and he has mounted tires on a lot of BST wheels. These are Dunlop Sportmax 03 plus tires which I really like. Oh well guess I will just leave them mounted on the stock wheels and look at another set of tires. Another problem here is the Covic 19 is really bad and we have gone into another partial lockdown and I expect the Ducati dealer to shut down for the next 30 days at least. May be a while before you get any feedback.

That's ok. I won't be riding until June here. I wouldn't complain about a two pound reduction in weight compared to specs. Maybe Brock does that just to make sure nobody can say their wheels are heavier than the published weight.

I'd suggest a set of Pirelli Supercorsas for the BSTs. Those were the lightest tires I've used and very good for twisties but they wear out quick. I have Metzler Comp K Slicks on the busa now and like them a lot. They're roughly the same weight for how much tire you have. The Super Corsas I used were 190/55s and the comp K slicks were 200/55. One pound heavier for a 200/55. The Dunlop Q2 190/55 I weighed was almost 2 lbs heavier than the Super Corsa 190/55.

No complaint Rook, just curious about the weight discrepancy.
Took off stock fuel cap and installed a RSS alloy cap today.
Stock cap & screws--13.7 ounces
SSR cap & screws--5.6 ounces
Also removed a tank bag mount with the stock fuel cap--1# 1.2 ounces
Just trying to do a little something everyday to break up winter boredom. Lots of stuff left to do besides new wheels that I have sitting here:
1. new EBC HH brake pads
2. Install HealTech quick shifter
3. Install Scotts dampener
4. Install new Shorai battery
5. Winter maintenance
6. Install new 2nd Rizoma bar end mirror on right side
7. Install new carbon fiber chain guard
8. Install carbon fiber front fender

Probably something I have forgot that is sitting here.

ust trying to do a little something everyday to break up winter boredom. Lots of stuff left to do besides new wheels that I have sitting here:

It sounds like you have some nice part going on the bike you'll have to show us some pictures.

Long retired Rook (11 years ago). That and being stuck at home during Covic is the reason for the boredom. Fortunately it doesn't get as cold here as Michigan and I can still work in the garage.

Rook the tire weights for the two Dunlop Sportmax Q3+ tires are
120/60/17---8# 3.1 ounces
190/50/17---13# 3 ounces
These were the tires that came on my 2012 ZX14R and I decided I liked them so much I would put another set on the BST wheels. Not the lightest but a really good tire. Going to leave the other set on my stock wheels.

Dang, that's right in there with Pirellis. The 190/50 would be a lb more for a 190/55. I've only used 120/70s for the front but your 120/60 is over a lb lighter than any I have weighed.

Thanks for the info. I'll file that away for the future.

Ok I couldn't believe the rear wheel weight was that much lighter than Brock's site listed and it isn't. The sprocket
carrier assembly was in a separate package and when the wife brought them home from Fedex she didn't bring that package in from the car. The correct rear wheel weight is 9# 4.9ounces. This includes bearings, sprocket carrier with bolts & nuts, disc carrier, cush drive. I went back and re-weighed everything else including the front wheel & tires and everything else weighed exactly as listed. Sorry for the mistaken total rear wheel as shipped.

Stock 2012 ZX14R front fender weight is 2# 6 ounces. Installed the CF front fender & CF chain guard today. The CF chain guard is only 3.2 ounces lighter than the stock one. Maybe not worth the price for the chain guard for weight savings but it sure looks good. Rook I changed out the stock brake pads today to the double H sintered ones. The previous owner told me the pads were probably near cooked due to him riding hard in the mountains for near 9000 miles. They were only 1/2 worn out so didn't need to be replaced. Labeled them and put them up for future use if necessary. Weights of the new HH pads were same as you listed.

I am still waiting on new Driven rear sprocket before changing stock wheels over to the Rapid TEK CF wheels.
