Features

  • Compatible with: The 428 17t front sprocket is compatible with most of most of 50cc 70cc 110cc 125cc Pit Dirt Bike ATV Quad 4 Wheeler, such as SSR 125, Taotao DB27, Apollo RFZ110 X15, X18 Z20 Z40, Coolster 125cc, CRF100, Boom Vader 125cc, X-Pro 125cc 140 cc, NS125 Pit Dirt Bike, TRX90 ATV Quad 4 Wheeler
  • Robust and Durable: The 428 front sprocket is crafted from refined high-strength steel and undergoes high-frequency quenching heat treatment. This significantly enhances surface hardness and overall toughness, effectively resisting tooth deformation under tension. It ensures long-term stable performance and reliable chain engagement, maintaining enduring and dependable drivetrain functionality even in challenging terrain
  • Optimized Transmission Performance: The 428 17t sprocket adopts a 17 tooth design, with precise tooth profile and smooth surface treatment, effectively improving chain meshing efficiency, reducing jolts and noise during cycling, and providing reliable power transmission for off-road and daily cycling. And the 17 tooth front sprocket has the maximum potential for maximum speed and lower engine speed during cruising, and performs well in highway driving and fuel economy

  • Note: If you hear the squeaking sound of the chain while riding at low speed, or feel the vibration or hear the clicking sound when rolling the bike forward or sliding to stop. Anyway, you need to check your front sprocket. When this specific component begins to malfunction, it is best to replace it immediately

  • Perfect for a grom clone!!
Size: EG428-17T-17mm Style: 17mm
Definitely an improvement from the stock 14 T sprocket on my Grom clone, helped to bring down the RPMs while going fast and still has a good balance of torque, I've had no issues so far, I've ridden 900 miles on it and it seems to be very good quality!!
