SWM MC 125

The MC 125 is a vintage motocrosser built to rev and reward a busy right wrist. Top-end rebuilds aren't optional on this two-stroke — skip them and you'll lose power or pick up a seizure. Check the reeds for cracks and the air boot for splits. Any leak there will lean the mixture out and cook the piston.
