RED MOTO CRF 300 R

Big-bore conversion of the 250 platform. The extra capacity hits harder mid-range and pulls taller gearing, which loads the top-end and the cooling circuit. Watch piston and ring intervals. Run a chain and sprocket set rated for the torque step up. Most chassis hardware crosses over from the donor 250, so plastics, controls and suspension parts share fitment.
