Looking for some help. Have a new to me/my boys hammerhead torpedo w/ 136 cc. In great shape, but curious if anyone knows the specs of the rear wheels. Would like to find an aftermarket rear wheel for a couple different reasons. 1. The rear is about 4-6” narrower than the front. I’d like to have a higher (numerically lower) offset wheel to push the tires out for a little more stability. 2. I’ll be going to a taller and wider tire to reduce the speed a little. Any help directing me to info on the specs on wheel that would work is appreciated.
