The JT SPROCKETS ultra-light aluminum 460 - 520 (manufacturer part number JTA460.49BLK) is designed for motocross riders looking for a robust and lightweight transmission part to modify the gearing or replace a worn sprocket. Made from Ergal 7075-T6, this aerospace alloy offers a good balance between mechanical strength and weight, while maintaining a discreet black finish suitable for off-road use.
- Material: aluminum 7075-T6 (Ergal)
- Number of teeth: 49
- Chain pitch: 520
- Type: standard
- Color: black
Mounted on a compatible 520 sprocket, this crown allows you to adjust the gearing according to your riding style and track conditions. Its "ultra-light" design minimizes unsprung inertia, which can be felt in the responsiveness of the rear wheel without compromising reliability when properly maintained.
Examples of compatible models:
- KAWASAKI KX 450 (KX450J) 2022
- SUZUKI RM-Z 250 2006
- KAWASAKI KX 250 (KX252B) 2020
