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 noticeable change in performance over stock despite compression ratios being similar.

MEDIUM COMPRESSION: Higher compression ratio than stock but still very safe with 95 or 98 RON fuel. Gives much smoother power delivery at low/mid revs and a nice increase to bottom/mid power especially. Squish clearance is much tighter than stock. Fuel economy is improved over stock. This is the most popular design for 300 models between sea level and 1500m and works extremely well when combined with our ECU tune.

HIGH COMPRESSION: Requires 98 RON fuel near sea level.  Gives a very noticeable increase to bottom/mid power plus improved smoothness. Squish clearance is much tighter than stock. Fuel economy is improved. Recommended for riders who want lots more bottom/mid power from their TPI but are willing to sacrifice some peak power and overrev. Due to the increase in compression ratio over the stock head this design may require a thermo fan to be fitted for tight/technical riding. We also suggest an 8 heat range plug with this head. Our ‘High” comp head is lower comp than many other aftermarket heads and is better suited to our local conditions and fuels. This head will also suit high elevation riders from 1000-1500m who want a nice increase in torque using normal pump fuel.

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.

A note about TPI ECU maps… 
We strongly suggest reflashing your stock ECU at the same time as fitting this head. Our updated fuel and ignition maps make the bike much smoother, more powerful and much safer than stock. We also add more oil and have had brilliant reviews of our head and ECU package from happy customers all over the world.
See out listing for ‘Power Kits’ for more details. Our TPI Power Kits are easily the best value for money engine setup available for the TPI bikes anywhere in the world!

 

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 and tested in-house by TSP in Australia.

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.

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