Anyone ever install a CRF450R Rear Brake Master Cylinder?

I know the CBR600RR guys are doing it... It gets rid of the remote reservoir.


I personally already have a reservoir delete, but am always looking for something different...


I would imagine it should be very close to fitting properly, since it fits the CBRs...


Anyone done it?

I installed one from an RMZ250. The CRF model uses a tiny piston (11mm?), so I opted for the RMZ (IIRC 12.7mm) as it's closer in size to the stock unit (14mm) and still a Nissin (good quality MCs). You can see it in my recent pics

Picked it up on eBay, believe it was about 2006. I think you will find that most years KX-F and RMZ are exactly the same unit (FWIW and IIRC, Hondas use 9mm pistons and Yamahas 11mm). I picked up a banjo with a pressure switch, thereby allowing me to dispense with the entire switch mechanism. I had to redrill my stock rearset to accommodate the different spacing of the mounting bolts, rest was straightforward. I also ordered a Zip-Ty racing reservoir extender as the stock reservoir is quite small (made more so due to the angle it needs to be mounted at, can't fill it right to the top, so the extra volume was handy)
