Want a better start off the line on your pit bike or dirt bike? This launch control device mounts on your 48mm front forks and helps you get a killer holeshot. It basically locks the front suspension down a bit when you're staged, so when you launch, the bike doesn't wheelie as much and you can get more power to the ground. It's a simple mechanical add-on that can shave time off your starts. Make sure your forks are 48mm and check the pictures to confirm it's the right part for your bike. Good quality, and we're here to help if you have questions. Comes as a complete kit with all the parts shown.
