View Full Version : Getting rid of the abs
Hi
New to this site, just got an SV that has abs - we'd like to fit hel hoses - race set up front. Any idea on how to lose the abs so that it won't upset anything else? - Warning light on clocks?
Cheers
Ted
just change the lines then bleed the system properly. i dont know why anyone would want to turn off ABS.
We are putting the bike on the track. Best to not have abs..
why... ABS can stop/slow a bike quicker under heavy braking than no ABS even on a track. unless its for removing the whole system for weight saving then ok fair doozzz then just put up with the spazing dash.
ABS works by sensing when the wheel/tyre starts to skid, without it you have a higher chance of locking up and skidding. unless your some track guru like Valentino Rossi then its not going to make a whole lot of difference.

Is it a Gen 2 (pointy)? If it's for the track, you can remove the ABS module, pump, relays, the solid brake lines etc and just run conventional lines direct from the master cylinders to calipers.
Disabling the ABS does nothing apart from light up the ABS warning light and put an error code in the ECU, it doesn't affect power. You could stick a piece of tape over the light or remove the bulb. The ABS is 'failsafe' so if any component does fail, the brakes still operate conventionally but without anti-lock.
Yes, L4 pointy. Does the abs have it's own fuse? If yes, where is it and would disabling it stop it getting its knickers ina twist/cancel the warning light? Just an idea... .

A skidding tyre has less grip than one that is just on the point of skidding - I would never remove ABS from any vehicle. ABS can cause problems on snow and loose surfaces though.
So you're telling me that all pre-abs motorcycles are ****e?
Don't think I ever had a front wheel lock up on any LC/RGV/KR1S etc.. that I owned.
Maybe abs is just some kind of modern day namby pamby save the gay whale faggotry thing? I dunno... .

I had some sympathy with your request up until this last post, when you just blew any credibility out of the water. That last sentence did it I'm afraid.

...it was a bit unpleasant to read.
Anyway, don't know whether this will help but here's a link to the supplementary wiring diagram for the K7 showing there's a couple of fuses for the ABS:

the fuse location is on the previous page #77.
Apologies. No offence intended.
Just get really hacked off with everything being so over the top health & safety wise in this stupid modern world..

Health and safety ain't all bad, especially if it helps in desperate situations where braking really hard in less than ideal road conditions does not require highly tuned braking technique with ABS. I have had ABS on AL7 cut in a couple of times just after I had the bike ( before I had chance to fit LED headlight bulb and extra DRL lights ), once approaching a junction and vehicle looked set to pull out in front of me and there was banding in the road from repairs, road was damp and ABS saved front wheel from skidding. Another was on gravel in road, again near a junction where a car started to pull out across my path and then stopped - phew....
Since I have fitted the extra lighting nobody has even looked like cutting out on me, and hopefully I am more visible in the mirrors of vehicles I am following or about to overtake.

The OP said he is putting the bike on the track-----a totally different ball game where ABS isnt normally used
Just remove a sensor/reading plate and crack on. Brakes should work as normal, and the ABS pump won't kick in.

MotoGP don't allow ABS because of advantage it can give riders..
I thought in theory a human could do better than ABS because the latter pulses the brakes off so momentarily losing braking force while a riding god can maintain a constant pressure on the point of locking the wheel. At least thats what I do....

You do that all the time, even in an emergency when the only aim is to stop as quickly as possible while keeping the bike shiny side up ? ? ? The ABS pump supplies pressure to braking system and its aim is to keep the wheels on the right side of skidding - which is where tyres have less grip anyway ( static vs sliding friction ).
Looks like I've opened a can of worms here.... .:eek:
Essentially the bike is being prepped for track days, with limited road use. So thanks to all you guys with the input on disabling the abs and I appreciate that some of you guys/girls would prefer the "safety" aspect of abs for road use... .
Anyway, next problem, the old battery looks like it's had it... . Is there a smaller lightweight jobbie that anyone can recommend?
Cheers
My SK1 has a Shido LTZ14S LiFePO4 type battery fitted with a MOSFET reg/rec, (FH012 or similar), works absolutely fine.
For track you could get away with a significantly smaller capacity Shido, as long as it can deliver enough current to start the bike. I would guess something like an LTX9 would be fine, 180A cranking should do the job comfortably. https://www.sportsbikeshop.co.uk/motorcycle_parts/content_prod/248942
It's 0.7kg against around 4kg for a typical 10Ah lead-acid battery, cheapest weight saving you'll find apart from having a good crapp before getting on the bike.
Power 5s on and yokes dropped 5mm. Feels like a totally different bike!
Looking at the original old tyres that came off her, it looks like it just ran up and down a motorway all day, centre really squared off and humungous chicken strips.... .
Onwards and upwards.
Cheers

But they do allow ... anti-wheelie, aero wings, belly pan scoops, traction control, launch control, auto suspension lowering for take off, engine mapping, seemless gearboxes, slipper clutches, quick shifters, etc. If they all had ABS perhaps no-one would have an advantage and many wouldn't suffer front end folds and carreer ending injuries! Just a thought.
