KTRC...?
09/03/12 9:02 AM

in first gear, doing 2 or 3 mph, fast as i can wide open throttle, bike goes daaaaaaaa, fills the ktrc meter , bogs down into full go nowhere mode, tells me its not just directly connected to wheel speed difference, it must know you are in first gear and in danger of flipping bike so it goes straight to limp mode, anyb0dy tried it?

I can pretty much say....your rear wheel is spinning.Mine will NOT wheelie doing that...it will "KTRC" until I get the bike rolling a bit(for traction)...then it doesn't interfere UNTIL the front slows down from being off the ground.And depending on what speed I'm lofting at....the wheel speed sensors MAY not immediately "catch on" that the front's actually slowing down enough to activate the KTRC....meaning....I have to manually close the throttle BEFORE she lofts OVERBOARD....and she will if I don't do something fast.Setting...'1'.My vids show this happening.

I think depending on your tire...and available grip...it will happen more or less.It doesn't take(with mine anyway)a huge amount of wheel spin to activate the KTRC.It senses it very quickly.The alternative is to turn it off...which I don't do for obvious reasons.

I think we have to remember...launching at 3K like at the drags is a bit different than punching it from a virtual dead stop.The KTRC (and bike) is gonna perform different than it would launching like a dragger.That's what I think anyway.My Dunlop will spin at low(low) bike speeds and applying hard throttle.Once it grabs...then the front comes up and the sensors start calibrating the wheel speed difference....if the front is rolling 'almost'(or as fast..which it will do for a couple of seconds if there's no rear wheel spin) ....the KTRC(in '1' mode)will NOT do anything until the speed differential is big enough...by that time...depending....she COULD go over.Mine's done that several times now.There's nothing wrong with it...it just depends on how everything is being 'put together' information wise in the ECU.

Hey Green,

Could this effect motero is experiencing be the "safety" codes in the ecu that Brock and others found independent of the KTRC?

Your ecu has been flashed, right? So does your Guhl flash take out the hidden codes that Kawi buried in there? You would then not experience this effect.

Just speculating.

Mine was the first Guhl/Brock flash....the codes are still in there.IDK if that's what he's having or not...it doesn't sound like it to me...but then...Brock's explanation of those codes were 'kinda' vague.(to me).They 'kick in' when the bike is moving pretty good...so I don't know really.Ivan's suggestion to me was to be in like 2nd gear...and get on it hard.He said the KTRC would activate subtly to 'save' the rider.Brock said basically the same thing.But I've never felt any limiting anywhere along the rev range...except when I momentarily spun the rear wheel...very slightly.That only occurred at like just off idle and punching it.Other than that...no limiting that I've felt or heard with mine.She rips straight up through the gears with big throttle...no secondaries however.So the 'effect' of fly smoothing or whatever isn't there with mine...I guess?


I have not tried any of the big power throttling with the KTRC in 2 or 3...so it may be more pronounced in those modes?

wheel is defo not spinning, no chance, it was in ktrc 3, road was wet last night , its dry this evening so ill try all modes later and report back.

Ya...KTRC 3...most definitely gonna restrict...

When I say 'wheelspin'...I mean breaking loose...not necessarily spinning in the conventional sense.I think that's one reason Brock and those guys test their 14R's in 'off' KTRC mode...cause that rear will 'slip' under hard accelerations in the right conditions...that dyno wheel being one.She'll do it on the street as well under the right conditions.The earlier 14's did(do) it all the time...just wasn't(isn't) that noticeable.(no KTRC to stop it).

Tires play a big role in the grip as well.My Dunlops will slip(on a straight hard bottom speed take off)...and grab with a reapplication of hard throttle.Sometimes.Depending.Usually.I love my bike;)


I will not hammer my bike when she starts to loft...nope.It WILL go over backwards...I've NO doubt about that.KTRC '1'.

All the talk about 'safety mode' programmed into the ECU...it doesn't kick in in these situations...I can tell ya that!My bike lofts so quick...it'd be OVER in a second or so....picking myself up off the ground.By the time that ECU figures out WTF is going on....the bike would be laying in the ditch!And that's no exaggeration right there.

This sounds normal to me and proves the TC on your bike is working OK. Mode 3 is the most intrusive of the 3 modes. The difference between the TC on the new 14 and that fitted to previous machines is that it is predictive as well as reactive so will prevent wheelspin before it actually starts by killing the power.

"Mode 3 is the most intrusive of the 3 modes".Yep....it knows for sure in '3'.Try that in '1' or 'off'.;)

I agree with you Pegscraper, mode 3 is predictive, and will or will try to prevent wheelspin,i think thats what i was trying to say

GRN i had front wheel in the air last night, and it came down via TRC, in mode 1, i didnt let off throttle, but rear may have come off ground too, i was gettin lift from a hump in the road, ill play around with lifting front and see how trc effects in mode 1

If you get this bike flashed on the ECU can you eliminate the need to turn the traction control off?Also can yo eliminate the flies slow opening.I like to know this before I buy one.If the wheel comes up so be it.I can control mine with my hand.
