Removal of the ABS for racing??

Hi Chaps,
i'm building a racing F3 675 and very particular on my front brakes etc on how they work and feel. So my question is can the ABS just be removed and cause no issue to the ECU or anything else?
This is my first bike with ABS as i'm use to pucka GP bikes so i want to get that hard hitting feeling you have with the Brembo Master cylinder, i have already removed the Nissin master cylinder as it was Shit even on the road, i personally do not think you will ever get that BANG feeling if the brakes have to go through anything but direct to the caliper.
Regard

You have 2 or 3 options really.

1. Blank the inputs to the ABS module and leave it fitted. Its extra weight but then the ecu & display is happy. clearly you will need much shorter direct lines to the calipers from and rear.
2. Remove ABS module, Fit direct lines and re-flash the ECU to correct the error messages.
3. possibly might work on an F3? Remove ABS module, Fit direct lines. if you switch the display into lap timer mode on the F4 it then ignores the ABS error (well does not display it). Not sure how long it will do this and whether or not it causes some other issues. simple to try just remove the fuse.

on all of the above turn the ABS setting to off on the display.

Feel free to PM me, not a problem. Not racing anymore, only use the MV on track now when I do an ACU test day with mates that I have built / rebuilt they're bikes. No probs on the reflash

If you have M40 monoblocks on the front, my advice is to order the F3 Oro hoses / F3 800 (2013) pre-abs. Startwin trading can get them for you.

I tried Frentubo aftermarket hoses on my F3 (m40 monoblock conversion) and it was a disaster. Cant comment on the rest as mine is non-abs.

I am in the same predicament other than the added bonus I cannot get my bike to run. I did the rcs19 master which somewhat improved the feel. nothing like on my other bikes tho presumably due to the abs and extra length of the lines as well. mine was to be a track bike and, well, the absis the least of my problems w it right now. I would imagine leaving everything hooked up for the rear brake and plugging the abs pump line to the master and running straight from master down it would feel much better and possible the bike would just think your never using the front brakes while retain the rear abs which either might be useful or of no consciquence due to not using It on track.

@dansoarr Option 2 will not work since the speed sensors are differently for ABS and non-ABS bikes. do you have a solution for that as well? I doubt a reflash only will do the job as the parts are different and at different positions?

That's correct I corrected that in a PM but here, my mistake.
Yep you would need the non-abs sensors and wire to the ECU, its a headache for sure.

The other option is what we used to so on the R1's before an electronics pack was available and basically dismantle the Bosch pump to remove the heavy solenoid block but leave the Electronics in place. It means you destroy the pump but save the weight and can run direct lines.
