YCF F 155 SM

The F 155 SM runs hot. That 155cc lump puts out real numbers for a pit bike, and supermoto duty stacks the heat load even higher. Stay on top of oil quality. Pull the clutch plates if the bite point creeps, and check throttle cables for stretch before race day. Tarmac chews tyres fast on these, so plan rear changes and bleed the brakes regularly.
