Hi

I would like to install some 2 piston brake calibers to Yamaha TR1 1982.

Does anybody know from what bike might be closest for this.
I was thinking Yamaha V-max but it had something like 85mm
Bolt distance..

I dont want to change the front fork because im trying to restore
The old look with better performance from engine brakes and suspension.

Hallo Sami,
I use the Hand brake cylinder from the old xj600 Diversion, with a adjustable handbrake lever. The Brake piston diameter is also 14mm.
In use with steel braided brake lines you get  a very good brake.

I know that this is an old thread but this may help people in the future. I have just fitted Yamaha MT-09 Tracer front master cylinder. The reason I chose this as that it retains the original look because the master cylinder is the same shape as original but also has 5 position adjuster too and for £15 off Ebay it was a good deal
