Change compression of your S3 STARS cylinder head on your Sherco trials bike. There are High, Standard and Low compression inserts available for the 125, 250, 290, and 300cc
The primary use of higher compression heads are when riding at high altitude due to the air being less dense, they can also be used to increase the torque of the engine but be careful as raising the compression to much may lead to pre-ignition (pinking) and detonation which can damage your engine, a higher octane fuel may be required to prevent this from happening.
The Standard head is the same compression as used by Sherco when the bike left the factory.
The Low compression head is great for riders who want a soft power delivery, it makes the bike easier to ride especially in slippy muddy conditions. Great for begineer riders.
