Steel Lightweight Self Cleaning - 45T 520 Pitch. The new standard in steel rear motocross sprockets. A unique self-cleaning design keeps the contact area clean from dirt and mud while significantly reducing weight. Made from heat-induction hardened C45 steel which lasts up to six times longer than a 7075 aluminium sprocket and greatly extends chain life.
*** PRODUCT NOTE *** The image is representative of the specifications on file for the product listing. We list these sprockets as RK Brand, in some instances we still have stock of JT Sprockets which may be used in the rare occasion that the RK stock is incorrect or out from the supplier. We clasify JT as a higher spec'd product and therefore this is an upgrade. Sprocket colour is best described as manafactuered finish so they are a steel/silver finish.
