Does a taller tire size affect KTRC.I've run 55's on several occasions.I've never noticed any change in the KTRC action.You MIGHT see a small difference if you put it in mode 2,or 3.1 is the least intrusive.It allows a certain amount of wheel spin,or slippage.That window of 'slippage' is kinda 'long'(timewise).Meaning...if I loft in KTRC 1..it will NOT intervene for several seconds...
If I do that in KTRC 2,it will intervene sooner.In '3'...it won't allow that front to raise(if you punch it in 1st,it'll pull timing immediately).You can try these settings and see just how quick or slow it activates.
Hub and Toledo are both right.Now if you want to split hairs,you'd have to be able to see the sensor inputs to actually tell when the KTRC started activating for any given situation.It doesn't just drop the timing,boom.It intervenes according to the inputs.Big or small.Asking if it'll affect the performance of the KTRC with a taller tire...it COULD,but you might not know it's doing it as opposed to having it kill a wheelstand with 'hard' throttling.This IS a good question.It's not just sensing the wheelspeed(front and back)...it's also reading the throttle inputs.It's designed to PREVENT conditions where a 'likely' loss of control situation might occur.That could be a bunch of scenarios.The closer you set to '1' or 'off'...the less it's gonna step in."off' would be NO intervention.'1' would be,'it's already happening and needs to be corrected'.
In '2' or '3'...it could well be affected by a taller tire.But probably not by much.
I think most here are used to the timing being pulled in an abrupt way...from hard inputs and such.But it doesn't change the timing everytime the same amount.It can pull timing very mildly,so mildly you wouldn't even know it was.The timing degree pulls are not set in stone.The KTRC is intuitive.
If you could set up a test and replicate it exactly the same with a 55...then a 50...with KTRC on the various settings...you might be able to see a difference.It'd be VERY difficult to do that though.EVERYTHING would have to be exactly the same.I'm sure Kawasaki has done tests like these...since they mention the 'non-recommended' tire install deal.They may however be covering their arses since they don't KNOW who's riding the bike,or what skill level they have or don't.
I've never had any problems with a 55 and the Ktrc not working safely.
The ABS also worked fine.It was working anyway...stopped me in the rain at 70mph without a skid or loss of control.FULL braking applied.
