Specification: Rear sprocket with 42 teeth, designed for use with a 525-pitch chain.
Material/Construction: Steel construction, precision machined for durability and performance in motorcycle chain drive systems.
Designed Use: Replacement or upgrade part for motorcycles (and possibly ATVs) that use 525 pitch chain and require a 42-tooth rear sprocket. Changing sprocket tooth count can shift final drive ratio and affect performance (acceleration vs top speed).
