Rear abs isolation.

[Hedgemonkey]

This may be a daft question, but after a hairy moment offroad the other day, consisting of no rear brake on loose gravel, I want to disable the rear ABS, now I know there are electronic switches to do this, but working on the principle that the sensor works with the slots on the hub and if it sensors a stationary slot it activates the ABS. Now in my way of thinking if the slots were covered with a thin plate simulating a rotating surface ( may have to space out the sensor) would this make the sensor think the wheel was still rotating when locked up. Hmmmmm.

That, like every other method that kills ABS that I've seen, will kill it front and back. It's way easier to pull a fuse.

The only way to kill ABS on the rear only would be to block off the stock rear brake lines at the pump and run a line directly from the rear master cylinder to the rear caliper.

Cheers Greywolf, I kind of guessed it wouldn't work, at the time I just hit the kill switch and got it back under control. I've got kind of used to the reassurance of ABS on the Tarmac so instead of fiddling I'll just  go into loose stuff with a bit more thought next time.

You said this could be done by removing a fuse right? I don't suppose you know which fuse it is? :P that would be really handy to know as I'll be taking my '15 Strom on some lightish off-roading forays

I would imagine any of the abs fuses (if there is more than 1) would do it, as would disconnecting either of the abs sensors - basically, you create a 'fault' in the abs system & the abs part of the braking system becomes inoperative & will put the abs light on.
Be aware of any insurance implications if running on the public highway like this.

You don't need to pull an ABS fuse for light off road use. If you are going for steep downhills with loose surfaces or like to steer by swinging out the rear by locking the rear brake, removing the smaller of the two ABS fuses near the battery is the usual action. Be sure to remove the active fuse under the plastic cover rather than the spare fuse next to it that is not active. That would be the 25A fuse on the Wee or the 15A fuse on the Glee.

If you have a centre stand, pop the bike in gear, while running the engine spinning the back wheel, should be enough to induce a 'fault' & disable the abs. When you want it back on, switch ign off, back on & away you go

Christ GW, how much electrical stuff do you have on the bike?!

I think it's possible, though not simple.

I've made a tentative start, but other projects have got in the way. I think I can use a micro of some kind to read the rear (and maybe front) abs sensor outputs, and then feed the ABS unit a doctored signal so that it thinks the rear is never close to locking up. This would allow a 'switchable' rear abs, and it could be programmed to only turn off the rear abs above a certain speed perhaps...

There is also the much simpler option of installing a switch to turn the whole abs system on and off (on the fly) http://www.vstrom.info/Smf/index.php/topic,8792.0.html but this is for Wee's. The Glee will probably have different colour wires at least, or it may not even be possible? I haven't looked at a Glee wiring diagram.
