Downdraft Fuel Injection
Part of an entire engine overhaul last year, we gave the CRF450R a new downdraft intake tract and FI body to help increase both power and fuel-metering precision. It’s part of the reason the CRF450R offers such explosive power and massive torque, especially out of the starting gate and in the critical first 100 feet of the race to the first turn.
Dunlop MX3S Tires
Developed using Dunlop’s latest “block-on-block” design technology, the CRF450R’s MX3S tires give excellent feedback and are a perfect complement to the CRF450R’s frame and suspension.
Cylinder Head Layout
The CRF450R uses our latest finger-follower rocker design. The Unicam cylinder head remains the most efficient in the MX world, giving you the design and performance of a double-overhead-cam layout but the compactness of a single-overhead-cam design.
13.5:1 Compression Ratio
By revising the CRF450R’s squish area last year, we helped boost the bikes compression to an impressive 13.5:1. That means improved combustion efficiency for more power.
“In Molded” Graphics
With the all the time you’ll be spending in victory circle, you need to look your best. The 2018 CRF450R has you covered. Our “in molded” graphics look great, and stay looking good longer.
A factory skid plate is light and offers the engine and lower-frame protection that a racer demands.
