Hi
I have a dream to build 2-stroke supermoto bike
to make it true- I bought crm stoke hubs and rims 17x4.25 for rear and 17x3.0 front to my MK2
After that, I faced with a problem to buy spokes, no one can tell me what size of spokes I need (even guys that sell them)
Can anyone tell me what size of spokes I need, maybe place where I can purchase them ( I`m in search process 6 month and can`t get them)

For brakes I plained to buy front disk 310mm with 4-piston caliper from sportbike, radial master cylinder. Rear brakes will be stoke also I will use braided brake lines.

Guys need your advice, maybe some one already done similar changes for their CRMs to make them motards
Hope for your help

Wheel builders should know what length of spokes as hubs are basically XR400. Mounting a radial calliper will be problematic and with a 310mm disk and braided lines you might find a 4 piston calliper unnecessary. Best to upgrade master cylinder first.

There are no wheel builders in Ukraine, I must to buy spokes and build wheels myself, but what spoke length to buy I can`t find
also, are stainless steel spokes best to buy?

My previous bike before CRM was husqvarna sm610 with 4 piston caliper and 320 mm disk- now I want brakes so cool as was at husqvarna(super brake power with one finger)

If you can't get an answer here try XR forums. Stainless steel are easier to maintain but heavier.
