and so it starts!

I needed a project to keep me sane after selling the GSXR. Just didn’t realise that it was going to be a complete rebuild.

So what is a CCM 644 DS, well basically its a bitza. CCM built the frame and swinging arm then used parts from several different manufacturers, Brembo brakes, WP suspension, Suzuki XF650 engine, plastics from Yamaha and Honda. You could think of it as an uprated DR650. The DS part stands for dual sport, so many came with offroad and supermoto wheels.

Note: My bike is in supermoto trim, so some parts may vary.

Info on CCMs is a bit hit and miss, as was their build quality, so I’m documenting everything I use for future reference. You don’t have to use these parts, but it will give you a starting point. When searching for chassis parts I generally start looking at early 2000 ktm 250 exc stuff.
