Two Stroke Performance Cylinder Heads for KTM/HQV/GG 85
Two Stroke Performance Cylinder Heads for KTM/HQV/GG 85, machined from solid 6061 T6 aluminum stock, offer improved performance, reliability and fuel economy. They are the best bolt on mod you can buy for your bike! Each complete head includes a ‘Cap’ which offers improved strength over stock with a factory anodized appearance, plus a combustion chamber ‘Insert’ which is interchangeable in order to tailor the power delivery to your needs.
These billet machined 2 piece heads feature TSP’s proven combustion chamber designs and are a MUST HAVE mod for most current model offroad bikes. The combustion chamber designs have been used by thousands of happy customers and have been extensively dyno tested… the gains are consistent. There are also a large number of riders reporting much cooler running temps under normal riding conditions.
Add even more power to your 85 with a 12° Head and Piston! 12° piston/head combinations allow for ports to be open for longer and a smoother fuel charge flow. This gives performance increases across the powerband, especially top end over rev, without loss of compression. 12° heads MUST be used with a 12° Piston (sold separately).
- Consistent power gains throughout the rev range especially in the bottom/mid
- Improved fuel economy
- Greatly reduced risk of detonation
- Improved engine life
- Smoother power delivery
- Does not require race gas
- 100% developed and tested in-house by TSP in Australia
- TSP Heads include one insert (and insert O-ring), head O-rings and head bolt washers
- 85 Cylinder Heads include base gaskets to lift the cylinder to the required height
Available insert:
- High Compression – This combustion chamber design is higher compression than stock. It is designed to work with the stock base gasket thickness and gives a tighter squish clearance than stock. It gives a noticeable increase to bottom/mid power plus improved peak power, resulting in better pull out of corners and improved starts off the line. It makes for a more fun and more forgiving engine that’s faster from corner to corner. 91 octane fuel recommended.
Fits:
Note: If you are running a TSP or VHM 12º Piston you must choose the 12º Head. All other pistons use the standard head.
