The Dirt Tricks KTM65-48-D-B rear sprocket is a 48-tooth Chromoly 420 sprocket designed for KTM 65 SX applications from 1998 through 2007. Built for demanding off-road riding, this black rear sprocket combines a lightweight minimalist design with the strength and durability needed for motocross, trail riding, and extended seasonal use. It is engineered to provide dependable chain engagement and long service life while maintaining a weight comparable to aluminum sprockets.
Designed and patented by Dirt Tricks president and engineer Greg Burns, the sprocket reflects extensive experience with aerospace steels, advanced heat treatments, and FEA stress analysis. The Chromoly construction is engineered to be 2.5 times stronger than stainless steel, helping resist wear, deformation, and damage under hard riding conditions. Its black finish provides a distinctive appearance while supporting the sprocket's durable off-road design.
Fitment: This Dirt Tricks rear sprocket fits 1998-2007 KTM 65 SX motorcycles using the appropriate 420 chain and compatible rear sprocket mounting configuration. Confirm the motorcycle model year, chain size, tooth count, and mounting pattern before installation. Dirt Tricks backs its rear sprockets with a two-year guarantee and will replace the sprocket if it wears out under the applicable warranty terms.
