KTM MX 125

Old-school 125 two-stroke. Light, peaky, unforgiving. Keep it on the pipe and it still pulls. Pistons and rings are consumables on these — change them often. Check crank seals for air leaks before every meeting. Jetting has to be right or you'll cook it on a fast track. Fitment-checked spares for the rebuild bench. Filter by category, brand or price.
