Built to take a beating and keep on competing
The CRF450RX is an enduro-focused machine designed around a 450cc liquid-cooled single-cylinder four-stroke engine and a close-ratio five-speed manual transmission. The goal: strong drive out of corners, predictable traction, and the kind of control you can trust when the trail gets rough.
Engine & power delivery
450cc liquid-cooled four-stroke
At the heart of the CRF450RX is a 450cc liquid-cooled single-cylinder four-stroke engine. It’s paired with a Programmed Fuel-Injection system (PGM-FI) and a 44mm throttle body for crisp response when you’re modulating traction through rocks, ruts, and hardpack.
High compression & Unicam® valvetrain
A 13.5:1 compression ratio and Unicam® SOHC, four-valve-per-cylinder layout support strong, race-focused output. Titanium intake valves are part of the package for performance-minded riders who want a responsive feel across the rev range.
Transmission & gearing feel
The CRF450RX uses a close-ratio five-speed manual transmission—ideal for riders who want tight spacing between gears for consistent drive when you’re pushing pace. Final drive is listed as #520 chain; 13T/50T.
