Help and compatibility

Choosing the correct reference

TSP components are specific to each engine, year and configuration. Before ordering, confirm the brand, model, capacity, year and whether the bike uses a carburettor, TPI or TBI.

If in doubt, also send us the VIN, a photograph of the engine and the reference of the current part. The MotoXtreme team validates compatibility before proceeding with a special order.

Compression and fuel

Some heads and inserts offer different compression options. The correct choice may depend on fuel, altitude, engine preparation and intended use. Do not select a configuration solely by the advertised gain: ask for technical advice.
