No and no, you shouldn't be really using the front brakes enough, going downhill, to activate abs. Downhill is a rear brake game.

Also there's not ready way to deactivate abs for one tire and not the other. A fault in one renders the whole system in a fault state.
I disagree that when coming down a loose hill a properly modulated front brake is essential. The front already does 70% of the braking on flat land, even more so going downhill. It is critical to use the front brake, but with caution. Only using the rear leads to a LOT of skidding around.

Maybe you're doing steeper hills, at higher speeds, than I am. I don't skid out my rear wheel when doing a descent if you start at a slow enough speed. Then you're just modulating front and rear, but you really want rear not to activate the ABS if you really need to shed speed. But that's okay, you can disagree, it's a forum.

This is the perfect switch for me.

20amps cos I am crap at electrics

I am also crap offroad and not particularly good onroad. So. if I left the road I could quickly flick the switch to build up some debris in front of the tyres before the looming cliff dropoff. A "W" above the anchor would give me all the feedback I require...

I was debating on making up a bunch of these, plug n play; a little overbuilt, but very safe. I’m having trouble sourcing a reasonably priced push button interrupt switch which would make it impossible to forget to reset. 10awg. Switch would be accessible through the gap in the fairing.
As I’ve posted before, that wire is near 30 amps and live even when bike is off.
PS
Another consideration is your choice of switch; 30 amps DC is quite a bit and the switch must be appropriately rated.

Did you end up making these? Electrical is so daunting but I'd love to do this to my 2016 ES

When I did my GenI I fitted an 80A SPDT relay in series with the fuse and a momentary on switch on the clutch clamp on the bars.

The fuse circuit, now via the relay, is normally connected when the relay is off, and therefore a form of fail safe. If the relay fails, it fails such that the circuit is normal.

The momentary switch when held for 1-2 secs fires the relay breaking the circuit, mimicking a blown fuse.

The ABS stays disabled with the light on the dash indicating such until the ignition is recycled.

Works good whenever I feel the need to kill it which is usually on unsealed surfaces. Left thumb for 1-2 secs and the brakes work like traditional brakes.
Hey do you happen to have info on how you wired in the relay? i have a 40amp relay 10ga inline fuse just unsure of how to wire in the switch to trigger the relay to do it's thing. where are you pulling its power for the switch side of things.

thanks

The relay switch contacts are spliced into the feed to the ABS, either before or after the stock fuse, I don't recall, but whatever is easy to access.

12V is switched power via the momentary contact switch to the relay coil. I don't recall where I accessed, but there's plenty of switched 12V there.

There's not allot of info out there on how to do this, so I figured I'd post it up with some clear pictures.

I know there is allot of controversy here about whether or not you need to shut the ABS off. I don't like it off road, but I also like my Martini's extra dirty. It's personal preference, so please spare me the "You'll shoot your eye out" or "NASA designed this system so it must be perfect" warnings. I know you can disable ABS on the 2014, but I don't feel like putting it on the center stand and doing a rain dance while my friends ride off into the sunset.

Ok so I started this off breaking the 20a ABS SOL fuse, but that gives you a non-linear throttle curve, same with breaking the 7.5a ABS fuse. The way to do it is to break the 30a ABS solenoid ciruit.

I used a 25a switch from NAPA with a waterproof boot (NAPA Part# TG6139 & TG6571). They sell a great switch, it's very robust.
For wire, I used 14-2 Outdoor Lighting wire from Home Depot. I've used this stuff for wiring in all kinds of things, from motorcycles to race cars. The casing is thick, and it comes in 18, 16, and 14 AWG. For 30 amps in this application, we use 14.
I use weathertight, heat shrink, crimp connectors. Some people like to solder, I'm too lazy.

First remove the 30a ABS Solenoid fuse. The one we want to break is the one on the bottom. The top fuse is just a spare.



Next we want to install a 30a inline fuse on the hot side of the circuit, with blade connectors to plug in where the fuse used to be. The blue blade connectors are 14 ga, and the proper size for this application. When you are all done, it should look like this.



Now we run the wire up to our switch, mounted wherever you want, I put mine in the dash. A big fat glob of black RTV works great to keep water and dirt out of the bottom of the switch, and keeps the blade connectors on there until you want to pull them out.



Now plug the the blade connectors on the other end into the fuse block where we pulled the lower fuse. The switch essentially "breaks" the circuit, same as removing the fuse. Use a 30a fuse in our fuse holder, and you are all set.



Switch mounted and ready to go off road!



When you flip the switch to OFF, it will immediately disable the ABS. The SPEEDO and TCS will continure to work normally. To turn the ABS back on, flip the switch to ON, and cycle the key.

Do this mod at your own risk, and I will not be responsible if you smash yourself into the pavement because your ABS was off.
Perfect explanation.
Please make sure that the fuse is on the energized lead, before the switch!!!!!

Will disabling the abs effect the function of the traction control ?. Is the same module used?. Thanks

No, they're two separate systems. If you disable ABS you would still have the TCS system active unless you disable it as well.

To clarify, you're disabling the ABS pump, not any of the sensors that your ECU needs to calculate speed for traction control assist. All your ABS Disable and accompanying ABS light on the dash are telling is that the system is reporting no power at the pump so it won't be able to activate it. The TCS system doesn't rely on ABS mechanics to function, since it's not taking big swings at your hydraulics, just adjusting wheel rotation speed and torque calcs.

Hi,
I am kind of a wuss off road, and I’d like to keep the abs on the front tire (I think it’s saved my ass in a down hill in the dirt) but turn it off on the rear. I didn’t see this talked about. Is it possible (and desirable)?

Thanks,

ken
I had the ABS disabled but don't ride without ABS anymore because of the gravel roads I use. Sometimes there is too much speed and the roads are full of sharp curves. The front brake must not lock under any circumstances. Had few tricky situations when there was a lot of gravel on the road. However I would like to have just the rear brake disabled but the ABS must get back easily. That means not just simply to disconnect the rear master cylinder from the ABS-motor and put a new hose to the brake caliber. Anyone knows how to do it?

The inability to disable the rear shows that Yammi knew the world would disregard the off road chops of this bike. I didn’t care about this limitation until I descended a loose gravel hill and couldn’t stop until it flattened out, (very scary), thanks to ABS.

There is a thread here, somewhere.......I had to do mine until a new ABS was procured.

I don't think anybody has disabled ABS just the rear. Looked everywhere. Anyway, maybe the clean conversion is impossible without modifying the ECU firmware code.

You can bypass the ABS pump with some brake line and fittings. There is a thread on doing this if you seatch. I don't know of anyone changing the ecu to disable abs.

I know how to do it by physically disconnecting the ABS motor from the rear master cylinder. That's not what I'm looking for though. I want push button operation like many other bikes.
