The Dirt Tricks KTM-51-RAW Rear Sprocket is a 51-tooth, 520-chain sprocket engineered for demanding off-road riding. Manufactured by Dirt Tricks from high-strength chromoly steel, it is designed to deliver long service life, dependable power transfer, and consistent performance in challenging conditions. The raw finish provides a clean, functional appearance while retaining the strength-focused construction Dirt Tricks is known for.
Designed and patented by Dirt Tricks president and engineer Greg Burns, this rear sprocket reflects extensive experience with aerospace steels, heat treatment, and finite element analysis. Its minimalist design helps keep weight comparable to aluminum sprockets while providing substantially greater durability. The KTM-51-RAW is built for riders who need a sprocket capable of lasting through an entire season of hard use.
This 51-tooth rear sprocket is intended for compatible KTM motorcycles using a 520 drive chain and the appropriate KTM sprocket mounting pattern. Verify the motorcycle model, year, chain size, tooth count, and mounting configuration before installation. Dirt Tricks rear sprockets are backed by a two-year wear guarantee; if the sprocket wears out within the guarantee period, Dirt Tricks will replace it, subject to the manufacturer’s terms.
