Upgrade your off-road drivetrain with the Dirt Tricks BT-49-RAW 49-tooth Chromoly Rear Sprocket, engineered for demanding trail and enduro riding. Designed and patented by Dirt Tricks president and engineer Greg Burns, this rear sprocket reflects extensive experience with aerospace steels, advanced heat treatments, and FEA stress analysis. Its minimalist design delivers exceptional strength and durability while maintaining a weight comparable to many aluminum sprockets.
The Dirt Tricks BT-49-RAW features a raw chromoly finish and is built for use with a 520 chain. Dirt Tricks rear sprockets are engineered to be approximately 2.5 times stronger than stainless steel, helping resist wear, deformation, and damage during hard riding. The sprocket is also backed by a two-year guarantee, providing replacement coverage if it wears out under normal use.
Fitment includes select Beta motorcycles, including the 2017 Beta 350 RR, 390 RR, 430 RR, and 480 RR; the 2018 Beta 250 RR, 300 RR, 390 RR, 430 RR, and 480 RR; and the 2018 Beta 300 Xtrainer. Confirm the motorcycle model, year, chain size, and tooth count before installation. Manufacturer part number BT-49-RAW and vendor part number BT-49-RAW identify this Dirt Tricks rear sprocket.
