I'm a bit puzzled. From what I know bike traction control works by cross referencing the front and rear wheel speed the throttle position and the lean angel of the bike, or may be that bit is only Moto GP. any who. here's my question. I washed and cleaned my bike yesterday. to dry off the chain and back wheel I put it on the centre stand started the bike and ran it up to 4th gear and give it a few revs to spin up the chain and back wheel. How come my Traction control didn't kick in? I even tried leaning the bike over on the side stand and doing it again and still no spluttering engine or dash light flashing? what's the deal here? is it just fake?
comes in at just over 10 mph, but sure you get a warning come up on dash when you free wheel it on the centre stand DTC ??
Good point, I do that to dry my chain off and had up to 40 on the dash. I have noticed that nothing gets past you jc!
Maybe because it was a constant speed, i.e. not slipping. It wheelies ok so reckon its more to do with rev spikes on these bikes than wheel sensors. Mine certainly works, was on a bit of overtime on Sat
What's it like Bradders when it comes on. Do you feel it go and then it kicks in and all is well or does it kick in before you really know what's happened.
Flashing dash, but tbh only felt it cple rimes, on wet over banding but bike was starting to slide and on Sat with a big wheelie handful and it felt like it missed and dropped a cylinder, then back into life again
It's a pitty they didn't put a test mode on it so you can test it with out risking binning your bike. I tried all sorts to get mine to kick in on the stands. I think next time I'll get my son to spin the front wheel too.
just try it on a bit of gravel, or a dirt track. Very easy to get the TC to kick in then. And ABS. I test mine every time I go out down my drive :biggrin: I would guess (because I don't actually know) that when on the stand the TC will do nothing because the front wheel is not rotating. I assume the controller is inteligent enough to realise this. The TC looks for a difference in rotational speed, just the same as the ABS does. For it to work though they need to both be showing a similar speed to start with.
Your dash should say DTC off when you spin up on stand. It is likely to do with fact front wheel stationary. Has anyone tried a burn out? Not that we're hooligans on street fighters
I don't think the Multi DTC takes into account lean angle (to the OP). Only the new system on the KTM 1190 does that.
The traction control sysem is obviously sophisticated enough to realise that it should not activate in this situation. It might possibly be looking at front wheel and rear wheel speeds. Presumably, before it activates, both of these should be the same. There is a test mode. It does a self-test every time the ignition is turned on. Steve
The system on the RSV4 does too, its really weird you can wind the throttle wide open with the bike cranked over then it feeds you more power as you stand it up. Its like riding a bloody missile coming out of the corners!
I tried it on my 1198 by putting rear wheel on grass, holding front brake and spinning the rear. Even at 8 my DTC didnt kick in. However later that day it pissed it down and i'd left it at 8 and boy it was unrideable. No idea why it works when properly moving but doesnt when trying to fake it.
Exactly set it in touring mode, go find a gravel car park and give it some beans and you will feel the DTC kick in as it backs the power off to the spinning rear wheel
When my Multi had a dodgy connection to the front wheel ABS sensor both the ABS and the traction control would switch off with a DTS off warning on the dash. I'd have thought that the above situation of running the bike in gear on the stand would have duplicated that since there will be no signal from the front ABS sensor. The ECU certainly can't tell that you're running the bike on a stand, it's not that clever! But I guess that with the bike on the stand, although there is no signal from the sensor it's still connected.
sounds like the engines running on 1 cylinder, and loses power, its a bit of a wake up moment, and one that reminds you that should you have been on a less high tec bike, you would be on ya arse, or through a hedge backwards. like I said in previous post it doesn't seem to activate less than 10mph, ( moving not on centre stand ) I use standard setting in Touring mode, and I can get it cutting in on my access road which is concrete, it doesn't activate either if you do a standing burnout, with front brake on, ( yes I've tried )
Yes, works when cranked over too. There is some blurb somewhere supporting this, however I've felt/seen mine chime in cranked over and on the gas.
