Description

If you're running a 520 chain setup and chasing lap times, your sprocket choice directly impacts acceleration, durability, and unsprung weight. DRIVEN Racing's 42-Tooth rear sprocket delivers one of the lightest options in its class without sacrificing the longevity you need for serious track use. Their EST Technology balances aggressive weight reduction with extended wear characteristics—meaning you get the performance advantage without replacing sprockets every season.

This is a bolt-on upgrade that makes an immediate difference on circuits where gearing matters.
