This Speed Kit was named for the type of rider you have. If your child is an aggressive rider and you need to jump up to the next level in speed and power, we’ve created the AGGRESSOR SPEED KIT for you. Not only will it allow your child to hit the speed they want, it is upgradable to many stages.
This kit will typically help you gain 5-9 mph from stock speed.
