About this part

DirtyBike Ultra Bee Large Rear Sprocket – Acceleration + Efficiency Upgrade Built for riders who want stronger drive out of corners without sacrificing ride time, the DirtyBike Large Rear Sprocket is a simple, effective upgrade for your Sur-Ron Ultra Bee. By increasing rear sprocket size, you gain improved low-end torque and quicker acceleration—while maintaining a balanced top speed for real-world off-road riding. Manufactured from OEM-quality zinc-coated steel, this sprocket is made to handle the abuse of aggressive trail, woods, and race conditions. Precision-cut teeth with beveled edges ensure smooth chain engagement, reducing friction and wear for a more efficient drivetrain. Key Features: Larger rear sprocket for improved acceleration and torque Helps optimize efficiency for longer ride time under load OEM-quality zinc-coated steel for durability and corrosion resistance Beveled tooth profile for smoother chain engagement and reduced wear Designed specifically for Sur-Ron Ultra Bee off-road performance For best results and maximum drivetrain life, replace both front and rear sprockets as a set. Pair it with the DirtyBike Laser Chain Alignment Tool to ensure perfect alignment and minimize premature chain and sprocket wear. Ride harder. Pull stronger. Stay on the throttle longer.
