Compression Ratio
Please select the compression you want with your head below:

*** TSP Heads & Inserts now always include Cylinder head O-rings & Washers free of charge! ***

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.

Now updated to our new one piece design, with ease in mind for interchanging inserts for different riding conditions.

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.

VERY HIGH COMPRESSION: This design is targeted at high elevation riders above 1500m or 4500ft. It will help to make up for the power losses due to thinner air at high elevation. We strongly suggest you do not use this design below 1500m. At these high elevations this head design should give similar results to our Medium or High Comp heads at lower elevations.

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!

These TSP billet 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 Billet 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 Billet head. The customer takes all responsibility for ensuring that jetting is appropriate for their riding style and conditions.
