TSP CNC 12 Degree Head Insert – 2018-2024 KTM/Husky 85 SX/TC Models
*** This is a 12 degree style – Must be used with 12 degree pistons ***
This 12 degree insert is slightly more refined and offers more performance over our standard 85 head kit.
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.
The customer takes all responsibility for ensuring that their engine setup is appropriate for their riding style and conditions
This insert can be used with the stock cap design.
This head is available with the following combustion chamber option:
HIGH COMPRESSION: This combustion chamber design is higher compression than stock and requires a thicker base gasket stack than stock to achieve the correct squish clearance (base gaskets are supplied). It is suited to 91 octane fuel near sea level with appropriate jetting. It gives a very noticeable increase to power throughout the rev range, resulting in much better pull out of corners, improved starts off the line and faster speeds down the straights.
