** Please note – this listing is for TPI models, for the carby models please see the carby listing as it will include the required coolant plug in the head **

You will receive one complete cylinder head (cap and insert) to suit a KTM150TPI or Husky TE150i from 2020-on.

For the 150TPI models we also strongly suggest fitting our Power Kit which includes the Billet Head plus an ECU reflash and a new idle bolt. This kit addresses all of the 150TPI issues and makes the bike more powerful, much more fun to ride and most importantly much more reliable. See our 150TPI Power Kit listing here… 150TPI Power Kit

Our new TSP billet cylinder heads are machined from solid 6061 T6 stock and offer improved performance, reliability and fuel economy. They are the best bolt on mod you can buy for your bike! Each complete head includes a ‘Cap’ which offers improved strength over stock with a factory anodised appearance, plus a combustion chamber ‘Insert’ which is interchangeable in order to tailor the power delivery to your needs.

These billet machined 2 piece heads feature TSP’s proven combustion chamber designs and are a MUST HAVE mod for most current model offroad bikes. Our combustion chamber designs have been used by thousands of happy customers and have been extensively dyno tested… the gains are consistent and include: increased power throughout the rev range, improved fuel economy, greatly reduced risk of detonation, improved engine life, and much SMOOTHER power delivery. We also have a large number of riders reporting much cooler running temps under normal riding conditions.

The unique billet design has been 100% developed and tested in-house by TSP in Australia.

These billet heads will bolt onto your standard cylinder and are designed to work with standard base gaskets. If you are unsure of your current base gasket thickness we can advise the correct thickness to achieve the necessary cylinder height and squish clearance.

The customer takes all responsibility for ensuring that their engine setup is appropriate for their riding style and conditions

This head is available with the following combustion chamber option:

HIGH COMPRESSION: This combustion chamber design is higher compression than stock but is still suited to 98 RON fuel near sea level with appropriate jetting. It is designed to work with the stock base gasket thickness and gives a tighter squish clearance than stock. It gives a noticeable increase to bottom/mid power plus improved peak power, making it easier to lift the front end over obstacles, climb hills . It makes for a more fun and more forgiving engine that’s faster from corner to corner.
