S3 Inner head - low compression GAS GAS

S3 is the specialist in Trial and Enduro parts. Innovation and high quality are the key words guiding the design of the elements that will make a difference. Tested in all conditions, the S3 products are at the cutting edge of technology and equip the best riders and trial teams.

It uses the best alloys available, to obtain a better output & more traction. The advantage of these heads is that they can hold more water and have thicker walls which helps with the cooling rate, thus improving slightly low revs power.

• The inserts includes NGK short Spark Plug: BPMR6A and O-rings.
• It uses the best alloys available, to obtain a better output & more traction.
• Forging them eliminates the hot spots found on casted heads.
• Ensure a better cooling rate.

Low Compression insert : Reduces engine compression for a very smooth response. Makes the bike easier to control and puts less stress on the engine. Perfect for slippery conditions.

Advantages:

• Ideal for slippery terrain
• Easier to control the power
• Makes the bike smoother and more progressive
• Used by the top professional riders

Different compression Inlet, what changes?

Standard compression (STD): Higher torque and power at low revs. Even though it is similar to the original compression, you will notice the difference.
High compression (A): Possibility to add another gear, better traction and very clean response.
Very high compression (AA y AAA): Specially for altitudes over 1500m, or MX engine preparation.
Low compression: Incredible traction, smooth response, the best riders use it. It's a delight!
