R3 apparently doesn't have it as an option in the US
N300 optional
cbr300r optional
rc390 standard

I think they all have abs standard in the EU though

Can you go peep your bikes and see if the whatchacallit is the same on the 250 an 300? Check the OP :bounce:

nope, my 250 doesn't have a stock braking system in the front. Thing bites like mad, I've gotten the rear off the ground with it...at the track :angel:

The rear appears to be the same though, same type of reservoir in the same location mounted pretty much the same way. This leads me to believe that the front would be interchangeable as well.

stock 250 brakes can endo

interesting, I haven't managed to get the rear off on my 300

it's definitely not stock though, the caliper is massive compared to my 300 caliper.

if you slam the front it locks but if you ease into grabbing the **** out of it, you'll lift the rear.

Can confirm that the stock 300 brakes can endo. Only things changed on mine are the pads and line.

If you don't have a camera I suggest the contour. It's decently priced and very easy to use, csmith has one

O.P... I think if it were someone woulda said something by now... I've looked and looked and haven't found, when so many parts the interchangibility is easy to find... I'd say if you wanted it bad enough you could make it work, but plug an play is doubtful. Prove me wrong one way or the other... Inquiring minds :confused:ya know :clapping:

Brakes are the same. 250 new gen ABS > 300 ABS. 250 new gen non ABS > 300 non ABS. No idea in the pre-gen brake although I'd be surprised if he internals are exactly the same..

Definitely lifted the rear while emergency-braking my stock 250J
