Combustion chamber designs for the 300cc:

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 Sherco 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.
