Can we install disc brake on the rear wheel of Yamaha Fazer?
Yes you can change the rear drum-brake of your bike with disc-brake, but it is a bit complex task which requires skill and experience. Major tear-down of the wheel will be needed and you will need to disassemble tire, valve stem, wheel weights, ring gear, and drum brake assembly. You will also need an adapter plate to drill mounting holes and studs and bolts for the installation of disc brake. We advise you to take your bike to your local Yamaha service center or some experienced mechanic as they will do this task for you more precisely.
