Front Master Cylinder and Tire Question

[JerbGas]

Hey people,

Wondering if it matters whether I use an OEM replacement for the front master cylinder of my bike in the signature or can I buy a new aftermarket one? I want one with that rectangular metal cased reservoir. The PO dropped the bike and the plastic one leaks, so I figure if i drop it again, perhaps this may not be as prone to leaking.

Any brands or products you'd recommend over a $200+ dollar ones I keep seeing. I see plenty in the 20-50 dollar range that seem just as good. What gives?

Also, I seem to be having trouble finding a place to buy a rear tire!? The front I can find easily but I havent been able to find a site that stocks an OEM replacement size for the rear. Is it even necessary to match the specs completely? Or will the rim size match fine?

Any master with a 14mm piston will work. There are lots of good options on ebay. If you plan to use a stock type mirror make sure the master you select has a threaded lug with the proper thread size and configuration to match. Also, make sure the master has a brake switch built in. You may have to adapt the wires from your old master to the new but that shouldn't be difficult.

Regarding a rear tire, you don't need the stock size, just a size that matches to your wheel. If your bike has a 17" rear then a 120/90-17 tire would be a good choice. American Motorcycle Tire is my favorite place to order tires but there are other good choices as well.

Good luck.

A master cylinder is a MC. The bore size matters more than what bike it came from. I would consider a rebuild mandatory for any used MC you buy.

There are plenty of cheap new MCs on ebay. I was doubtful of the quality. Also there likely won't be any rebuild kits available if/when you need one. But if the MC is super cheap, it's probably cheaper to buy a new one than rebuild it. Of course, a rebuild on a new MC should be many years away.
