Moto Tassinari AIR4ORCE KTM SX-F350 2011-2012 / 250SX-F 2013

Moto Tassinari is the manufacturer of the AIR4ORCE tunable intake system, and the VForce3 and VForce4 reed valve systems. The AIR4ORCE intake system is a larger volume air boot that replaces the stock air boot on modern four-stroke off-road motorcycles. The power delivery is tunable via interchangeable velocity stacks that are included with the kit.

The VForce3 and VForce4 reed valve system is complete replacement for stock reed valves. The unique VForce design doubles the reed-tip surface which in turn offers numerous advantages such as, significant horsepower gains, crisper throttle response, improved acceleration, greater efficiency and durability.
