With the BBR Tuning Free wheel gas bike = Heavy Duty Axle Kit, you are guaranteed a sprocket that will always stay true. And because of the direct hub mount, less pressure is placed on the spokes. Normal sprocket mounting connects the drive sprocket to 1 side of the wheel by grabbing 18 spokes and sandwiching them with 2 rubber grommets. By mounting to the hub, the HD Wheel applies equal drive force to both sides of the wheel putting force on all 36 spokes evenly.
This model is for pull start motors, such as 4-stroke engine kits and 2-stroke engines with pull start modifications.
NOTE: Heavy Duty Axle kits are for EXPERIENCED bike and wheel builders. These kits do not come assembled or spoked, and come with no instructions.
