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!
