How To Loose 100 lbs from your Gen1 ZX-14

I’m currently at -75 lbs. With headlights, coolant bottle, switching to all aluminum brackets on everything and few other tricks I got up my sleeve, I will be awful close to reaching the goal of dropping 100 lbs off the fully faired big ol beast.

I will add a chapter to this thread very few days until I get the whole thing recorded. I will also post the latest weight reduction mods I do as they occur.

There is a dark side, also. The obsession with modifying has lead to install many parts that add small amounts of weight. Electronics, gauges, nitrous and the like has put a few pounds on. After I turbo this thing, I wont be surprised if most of what I lost gets put back on. In the future, I will also post a thread detailing the mods I did that added weight.

BRAKES

#1) Lightweight Rotors and Rotor Bolts
WEIGHT REDUCTION: 1 lb, 13.00 oz
Rotors may not net a big weight loss. In fact, some aftermarket rotors might actually weigh as much or more than stock.

You must have a Carrazzeria or Honda rim or to install CZ rotors.

REMOVE
OEM Front and Rear Rotors and Rotor Bolts
Total Weight: 8 lbs, 10.55 oz

INSTALL
CZ BIG 320 mm Front Brake Kit, Galfer Rear Wave Rotor and ProBolts Ti Bolts.
Total Weight: 6 lbs, 13.55 oz

CZ rotors produce an unpleasant vibration under heavy braking so regardless of weight, I will probably go with Galfers (2 lb, 12 oz/each) when I replace them.

#2) Aftermarket Brake Pads
WEIGHT REDUCTION: None
Considering they were brand new at the time of weighing, EBC HH Sintered Brake Pads were the same weight as OEM pads. Kevlar brake pads may a bit lighter.

This weight is a close approximation. There were a few bolts that were omitted in some of these photos. I will recheck complete weights in the future.

The Pro-Bolt fairing screw kit (not Dzus fasteners) would probably result in a 3 oz weight reduction.

maybe more

and more

How about you swap out this lightweight unit with your big butt?? Bet that saves an additional 100 lbs?

I wouldn't need the bike at all if I had that.

THAT is one FINE looking unit!!

I looked hard, giggity, for that option when I bought mine but I couldn't find it!!!

What about theese BST carbon rims?

Weight reduction 5080 grams or 11.2 lb. unsprung and rotating mass.

Best upgrade I ever did...

A lightweight rear swingarm could lower weight below the spring significantly. Didn't find any numbers neither on stock or custom swingarms though...

https://store.schnitzracing.com/dme-aluminum-swingarm-kawasaki-zx14r-06-11/

I'm almost ready to order some BST Rapid TEKs for the Hayabusa.

I would definitely find out exactly what those swigarms weigh before ordering. For one thing, it looks like 60" is the shortest wheelbase they offer and stock WB is 58.3" Also, if it's made for drag racing, it might be made for extra strength and it seems like it would be heavier than stock. Whatever WB you order probably would be made from the same kind of tube as the longest WB they offer and the longest one might need some hefty tube. Couldn't hurt to call ask though. A member on Hayabusa.org has beautiful a CNC carved swingarm he bought from Webike Japan. He said it was stiffer than the stock swingarm but probably not much of a weight loss. I was like $4000 though. I'm sorry, I don't pay 4 grand for a part that's heavier than stock unless stock isn't going to cut it for what I use the bike for.
