Our NEW CR500 2 piece billet head is 100% designed, tested and manufactured by TSP in Australia. It features and integrated decompression valve, upright spark plug hole and comes in a choice of different compression ratios. Like all our other heads this design also comes in our unique bronze colour.

 

Select your desired compression ratio from the drop down menu. All designs require the stock head gasket and stock base gaskets and offer significant improvements over stock heads.

LOW COMPRESSION Very similar compression ratio to stock but with an improved design, works fine with 91-98 RON fuel. Gives much smoother power delivery than stock and a much more stable idle. Squish clearance is much tighter than stock and jetting is easier to dial in. Best suited to stock bikes where the rider is looking for a more refined engine without a massive increase in pulling power.

MEDIUM COMPRESSION Gives a noticeable increase in power throughout the rev range, especially bottom/mid. Gives much smoother power delivery than stock and a much more stable idle. Works fine with 95-98 RON fuel. Squish clearance is much tighter than stock and jetting is easier to dial in. Best suited to riders who want extra bottom/mid punch, or on bikes where the exhaust port has been lifted a moderate amount (this is a very common mod and may cause a slight loss of bottom end power).

HIGH COMPRESSION Requires 98 RON fuel or higher.  Squish clearance is much tighter than stock. Gives more power everywhere. Best suited to riders who want maximum punch or who ride at elevation.

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.

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