For info I am looking at fitting a set of CCM R30 (Suzuki engined model, not Rotax version)alloy wheels to my MZ.
The rear will fit with different spacers and a dierent brake disc (the CCM one is smaller)
I will try the front one this week, but cant see why it shouldent fit with a different brake disc (320mm to bif for caliper mount) also the speedo drive is on the same side as the MZ. The CCM wheel uses the same front and rear wheel bearings as the MZ, with a special sleeve to take a smaller spindle on teh front.
If these wheel fit then there seems t be no reason why CCM off road wheels shouldnt fit.
Off road wheels for th CCM come up on Ebay Uk quite regularly.
