The KMC KS136 Toro is based upon the Red Bull OT3 Race wheel. With its machined bead hump and knurled bead seat, you won't have to worry about tire slippage at low air pressure or in high horsepower situations. If you are looking for a wheel that can be used for the serious offroad racer or the average trail rider the KS136 Toro is a great option.
