Performance

Downdraft Fuel Injection

Part of an entire engine overhaul for 2017, the new downdraft intake tract and FI body help and 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 new MX3S tires give excellent feedback and are a perfect complement to the CRF450R’s new frame and suspension.

New Cylinder Head Layout

This year the new 2017 CRF450R uses a new “in-finger” 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.

Higher, 13.5:1 Compression Ratio

A new combustion-chamber design with a revising squish area helps boost the CRF450R’s compression to new heights this year, an impressive 13.5:1. That means improved combustion efficiency for more power.

New “In Molded” Graphics

With the all the time you’ll be spending in victory circle, you need to look your best. The new CRF450R has you covered. New “in molded” graphics look great, and stay looking good longer.

Skid Plate

A factory skid plate is light and offers the engine and lower-frame protection that a racer demands.
