The CRF line was launched in 2000 as a successor to the Honda XR series. The CRF-R is a liquid-cooled four-stroke engine. They are designed to be utilized purely for closed-course motorcross racing. The CRF-R lineup lacks any extra accessories; like lights and electric start (Although offered as an option on the 2017 CRF-450R).

Stock suspension suffers from poor compression damping and limp rebound damping. The Race Tech Gold Valve allows you to tune both compression and rebound valving for vastly improved performance.
Based on the wildly popular Race Tech Suspension Seminars taught by Paul Thede around the world, this step-by-step guide shows riders how to make their bikes handle like the pros. Thede gives the lowdown on all types of suspension, including cartridge and non-cartridge forks as well as dual-chamber and nitrogen-charged shocks.
The three forces of suspension, testing procedures, even the black arts of chassis geometry: This explains it all. The book provides step-by-step photos of suspension disassembly and assembly as well as a detailed troubleshooting guide for dirt, street and track.
Machined billet aluminum with interchangeable inserts (+15mm, -15mm). Includes bearings and seals.
Showa removed the schrader valve on many newer rear shocks. Now you need a needle to recharge your shock with nitrogen after a rebuild. Race Tech built this unit just for that job.
The features of this tool include 300 psi capacity, bleeder valve and T-handle plunger pin chuck. Swivel chuck has a 12" flexible hose. Comes complete with instructions, carrying box and Schrader valve extension (required on some Showa shocks). Nitrogen bottles available at any welding supply house.
