Features

JT Sprockets Steel Sprocket 857 - 520 (Manufacturer Part Number: JTR857.47)

Designed for street, off-road, and ATV riders, this 47-tooth JT Sprockets sprocket easily integrates into a 520 transmission. Ideal for standard replacement or for modifying the gearing ratio, it offers a robust and straightforward solution to get your machine back in working order.

Brand: JT SPROCKETS
Reference: JTR857.47
Material: Steel (Carbon C49)
Color: Black
Number of Teeth: 47
Chain Pitch: 520
Type: Standard

The sprocket is made from C49 steel, a common alloy for transmission parts that combines rigidity and mechanical strength. Its black finish reduces glare and matches roadster, cross, or quad configurations. Suitable for common maintenance operations: replacement due to tooth wear or gearing adjustment to fine-tune acceleration or engine RPM.

Examples of compatible motorcycles (for reference):

YAMAHA TT 600 RE (DJ01) 2004
MZ 660 MASTIFF 2000
YAMAHA XT 600 E (DJ02) 2002
