Combustion chamber designs for the 300:

LOW COMPRESSION – this head was designed to suit extreme enduro riding or for riders who are more interested in smoothness over power gains.  It offers strong bottom end torque with a very smooth delivery that won’t break traction too easily. It enables the rider to use lower revs and less clutch when tackling hard obstacles.

MEDIUM COMPRESSION – this head is our top seller for the 300 and suits the majority of trail riders and racers who want better bottom and mid power and a small gain up top as well. The power delivery is much stronger and more tractable than stock and suits a wide range of riding conditions. best suited to run on 91 octane fuel from sea level up to 4,500 ft.

HIGH COMPRESSION – this head and suits riders who want harder hitting power everywhere, especially down low.  It completely transforms the TPI into a weapon. Also best suited for normal trail riders who live at higher elevation from 4,500 ft and above. Best with 91 octane fuel.

VERY HIGH COMPRESSION – this head design suits very high elevation riding above 6,000 ft. When used at the appropriate elevation it will give similar results to the Medium or High Compression heads near sea level.
