I'll throw some info in . THE FJR1300 ABS was terrible it would kick in way to early , and shudder hard . Now its linked brakes were rear brake applied would activate the right from bottom pistons ( 2 ) on one caliper only .
If front only was applied nothing would happen out back . Lever feel was good on the FJR . @ Drag strip doing a burn out would cause a ABS code that took 20 miles to clear of normal riding .
Hayabusa ABS testing . Smooth , and would not lock up . I once was going 45 mph roughly , and stood up . Then applied all my weight to the rear brake . A tiny chirp for milliseconds then just slowing down .
Straight up , and down cruising 60 ish mph applied front / rear HARD at same time . Nothing but smooth slow down very rapidly . Lever always felt like crap no mater what .
Hayabusa after ABS delete , and Upgrades like rotors/pads/master cylinder / lines make for a amazing combination I wouldn't give back . One finger stoppie capability. Amazing feel , and feed back . Stops far shorter than when the abs was on .
Do I recommend ABS delete ? For me of course , but you have to decide for yourself
