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.
