S3 Zylinderkopf - hohe Kompression für: Gas Gas für EC250

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. 

• 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.

High Compression inserts : Designed to increase compression and give more instant power. The power is output is more dynamic but still very useable.

Advantages :

• Quicker response than the standard motor
• Engine will rev out more than the standard
• Extra power and transaction at the top end of the power band

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): Better traction and very clean response.
Very high compression ( AA y AAA): Specially for altitudes over 1500m , or special engine preparation.
Low compression: Incredible traction, smooth response,the bests riders use it. It's a delight!
