2021 CRF450R
OWN EVERY MOMENT
Model updates: Every part of the CRF450R is new for 2021, save for wheels and engine, with the comprehensive update benefiting directly from knowhow gained by the development of Tim Gajser and HRC’s 2019 championship-winning CRF450RW works machine. The new frame and swingarm, plus changes to geometry and suspension, save weight and greatly improve cornering performance. The engine receives intake/exhaust upgrades, new decompression system plus single exhaust muffler to boost and smoothen low-mid-range driveability. A larger hydraulic clutch offers greater control with lighter lever pressure. More compact plastics and a smaller seat unit increase freedom of movement.
For 21YM the CRF450R receives a wide array of improvements and upgrades under a development theme of ‘Razor-sharp Cornering’. Firstly, it’s 2kg lighter, thanks to a revised frame and subframe. The new frame and swingarm’s rigidity balance, combined with tighter chassis geometry, heightened ground clearance and suspension changes, are all targeted at creating optimal cornering performance. Learnings from Tim Gajser’s championship-winning 2019 campaign reduce rider fatigue, allowing enthusiasts of all ability levels to consistently post optimal lap times.
The engine also benefits from HRC’s knowhow to give a strong focus on low- to mid-range torque. The decompressor has been relocated, airbox volume is up, the throttle body redesigned and exhaust ports re-shaped. The exhaust downpipe is new and a single muffler replaces dual mufflers.
A larger-volume hydraulic clutch has an even lighter lever action, while other weight-saving details include a smaller fuel pump and optimised magnesium cylinder head cover. New plastics, too, are lighter and slimmer to aid rider freedom and the seat is a smaller unit, lower at the back. A smart new all-red graphic scheme completes this major update.

- In Mode 1 the system intervenes most lightly, and after the longest time – useful for reducing wheelspin and maintaining control in tight corners.
- Mode 2 naturally offers a mid-point between 1 and 3 in terms of speed and strength of intervention.
- Mode 3 has the system intervene more quickly and strongly, and is therefore useful in more slippery, muddy conditions.
- Level 3 – 8,250rpm, muddy conditions/novice.
- Level 2 – 8,500rpm, dry conditions/standard.
- Level 1 – 9,500rpm, dry conditions/expert.
