The 60/100-10 50cc SR Front and 70/100-10 JR & SR Rear. These tires are designed with the compound and performance that professional riders are using on the big stages. This tire offers low rolling resistance but also offering enough grip to hook up to the dirt to get massive holeshots.
The optimal air pressures are 14-16 psi. Use of rim locks are highly recommended because of the traction provided from racing compounds.
