What is the AIR4ORCE?
The AIR4ORCE is a tunable intake system via interchangeable velocity stacks.
What does it do?The AIR4ORCE tunable intake system allows the user to now change the power characteristics to suit track conditions and rider preference.
What can You expect after installing the AIR4ORCE tunable intake system?
Depending on the chosen velocity stack installed in the AIR4ORCE you will gain better throttle response and bottom and mid-range power (with longer velocity stack), or better throttle response and mid-range to top (with the shorter velocity stack installed).
What is a velocity stack?
A velocity stack is a device of differing lengths which is fitted to the air entry of an engine's intake system, carburetor or fuel injection. It is designed to:
Allow smooth and even entry of air at high velocities into the intake tract with the flow stream adhering to the pipe walls.
Modify the dynamic tuning range of the intake tract by functioning as a resonating pipe which can adjust the frequency of pressure pulses, based on its length, within the tract.
Will other velocity stacks be available in the future?
Absolutely. As Moto Tassinari continue to work closely with the Factory race teams they plan to develop model specific "race spec" velocity stacks that will be available in addition to the two velocity stacks included with each AIR4ORCE tunable intake system. Please keep in mind these velocity will be in extremely limited production, and the pricing will reflect that.
What is involved with installing the AIR4ORCE?
Remove subframe (using directions provided in your motorcycle manufacturer's owners manual), remove rubber boot between airbox and carburetor throttle body, and replace with the AIR4ORCE.
Why did Moto Tassinari feel this was needed on modern four-stroke motorcycles?
When Moto Tassinari begin focusing on four-stroke motors for our next product, they knew one thing for sure. They did not want to add to the already saturated market of gimmick type products, that are truly questionable in regards to how much performance they offer. They knew they wanted build on their solid reputation of the VForce3 and create a product that actually makes an improvement in power, throttle response and ridability. So they chose to stick with what they know, air intake, and that is how the AIR4ORCE was born. It's been a solid two years in development and is now ready for the marketplace after countless hours of dyno and field testing as well as being tested by such teams as GEICO/Honda, TLD/Lucas Oil/Honda, DNA/Shredstix/Yamaha and more.
What is included when I purchase an AIR4ORCE?
Moto Tassinari product line brochure, Moto Tassinari and AIR4ORCE decals, detailed installation instructions, two velocity stacks, AIR4ORCE tunable intake system and hose clamps and gaskets where necessary.

…the bike was more responsive and quicker to rev with the AIR4ORCE, which makes the bike respond better, act more nimble, and even feel lighter.
The AIR4ORCE gives me an advantage everywhere on the track, making the AIR4ORCE intake a must have.
