KM H-K1 EvoII optional plastic pulley
KM Racing introduce new optional belt pulley for the H-K1 EvoII nitro sedan. Made from plastic the 25T belt pulley is lighter than the all-aluminium part and allows for easy part swaps due to the lightweight aluminium pulley mount. The mount is the same as the 23T pulley and must be used in combination with the HK390B-P middle belt.
