CRF450R Engine

The CRF450R's PGM-FI fuel-injected, 449cc single-cylinder engine has been re-tuned for major gains in the low and mid-range torque area – with no loss of top-end power – plus a refined connection between throttle and rear tyre; key for finding maximum rear wheel traction. Durability and reliability have also been improved and a redesigned, lighter clutch is easier to use. Short, dual mufflers contribute to mass centralization, improved low/mid power delivery and provide a slimmer side profile.
