Disc brake Conversion: Joe dirt style
Does any body know a easy path to a china disc brake conversion for the 2001 50 SR. I know I sound cheap but I know those china discs work alot better than my drums at 64mph. I heard trafficjamz worked something like this but could not find the thread. Thanks
p.s. My wife and I went to the gym on my purple elite tonight and hit around 50-55mph... Thats about 330lbs!!! My temp got to 397 F. What is melting point?

Factoring in a small amount of error in the temperature reading and you almost assuredly have passed 400*F

I personally wouldnt know about the Chinese brakes, I have only done a Dio ZX disc swap on my NQ50...

Re: Disc brake Conversion: Joe dirt style
Using the disc setup from a '90s Dio AF35 might work, but when you look at one (see photo), there's a lot of parts need to be swapped out. There's a couple for sale on craigslist, but at $750 it might be cheaper to sell yours and buy the AF35 rather than buying it for parts and doing the conversion.deuce217 wrote:Does any body know a easy path to a china disc brake conversion for the 2001 50 SR.

You turn your bike off while its that hot? I let my bike run whileSpreeMadness520 wrote:Ive seen bores hit 450+

Cooling down so that way the fan circulates air around he cylinder and also so the piston and cylinder cool down at the same speeds.

Re: Disc brake Conversion: Joe dirt style
The steering stem and fork angle is all wrong if you are trying to do the sa50 elite. The '87 se50 elites are straight swaps for the live Dio fork/tree setup.
You'll have to buy the kit that's available in Hawaii$$$$.
Personally, you're better off buying an '87 elite.

Thanks guys, I purchased a used brake lever and caliper assembly with front rotor, off ebay for 25.00 for a 50cc china bike. I am gonna try to make something work.
