With the CRF450R MX machine as a base, the CRF450RX already has an advantage and along with its enduro-specific equipment – larger fuel tank, 18-inch rear wheel and sidestand – its twin-spar aluminium frame saves weight and features a factory-rider rigidity balance with super-sharp steering, huge ground clearance and RX-specific suspension settings.
The seat unit’s small (and lower at the back) and plastics slim and lightweight. Delivering strong mid-range power, the engine uses new ECU settings for even smoother throttle response and precise delivery. The decompression system minimises stalling and hydraulic clutch is built tough, with light lever load. HRC Launch Control owns the first 100 metres and HSTC manages rear wheel traction.
