Select your desired compression ratio from the drop down menu. All designs will work with stock base gaskets and cylinder heights and offer significant improvements over stock heads.

LOW COMPRESSION: Roughly the same compression ratio as stock EXC or TE, much tighter squish clearance and better design than stock, suited to Extreme Enduro, resists overheating very well, pulls from very low rpm smoothly and predictably. Still gives a very noticeable change in performance over stock despite compression ratios being similar.

MEDIUM COMPRESSION (suits 90% of riders): Our standard design, higher compression ratio than stock but still works fine with 95 or 98 RON fuel. Gives a very noticeable increase in power throughout the rev range. Give much smoother power delivery at low/mid revs. Squish clearance is much tighter than stock. Fuel economy is greatly improved over stock. Recommended for most riders.

HIGH COMPRESSION: Requires 98 RON fuel or higher.  Squish clearance is much tighter than stock. Gives maximum bottom/mid power but less overrev. More aggressive power delivery. Will overheat more easily in tight conditions. Suited to high altitude riding or MX. We do not recommend this design for normal trail riding or enduro racing near sea level. Contact us first if you want more info about this design.

Our new TSP CNC 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! Our design offers better heat dissipation than many other 2 piece designs due to the large lower section which incorporates the combustion chamber… this allows heat from combustion to disperse over a larger area than other 2 piece designs for improved heat transfer to the coolant.

These CNC 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 hundreds of happy customers and have been extensively dyno tested… the gains are consistent and include: increased power throughout the rev range (especially bottom/mid), improved fuel economy, greatly reduced risk of detonation, increased top end life in many models, and much SMOOTHER power delivery.

The unique CNC design has been 100% developed, machined and tested in-house at TSP.

These CNC 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.

We can also advise baseline jetting specs to go with your new CNC head. The customer takes all responsibility for ensuring that jetting is appropriate for their riding style and conditions.

This head is not suitable for TPI models. Contact us for info on TPI heads.
