The CCM 644E is nicely balanced both on and off-road, though at higher speeds (over 80mph) on tarmac the motorcycle's tall wheels begin to feel vague in corners. The Brembo brakes are excellent and probably offer too much power on the dirt. The CCM 644E's WP suspension works well in either environment with plenty of adjustability available.

While the components on the CCM 644E are from some of the names in the business the quality control at CCM has historically been poor – welds snap, bolts sheer and exhaust header pipes crack. CCM 644E's made between 2003-2004 are particularly prone to problems.

On one hand you get top names like WP (suspension), Acerbis (plastics), Renthal (bars) and so on with a CCM 644E. On the other the dash is small and hard to read.
