2003 CCM 644 Dual Sport Trail[edit | edit source]
The CCM 644 is nicely balanced both on and off-road, though at higher speeds 130 Km (80 mph) 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
