Moto Tassinari


Welcome to Moto Tassinari

Moto Tassinari is the manufacturer of the AIR4ORCE tunable intake system, as well as 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.

Now available to the public, the KTM AIR4ORCE tunable intake system

Though the Moto Tassinari AIR4ORCE tunable intake system has been a key part of the ÖHLINS/Langston Motosports/KTM engine package, it's only now become available to the public. This is the exact same AIR4ORCE intake system that the JDR Motorsports, ÖHLINS/Langston Motosports/KTM and Munn Racing teams have been racing with in the 2012 Supercross series.

Dirt Bike Magazine KTM VForce4 Review

The all-new VForce4 scores high with Dirt Bike test riders

Dirt Bike magazine recently reviewed the all-new Moto Tassinari VForce4 for the KTM 250/300 models in the June 2011 issue. While two-strokes may be flying under the radar in some publications, that isn't the case with both Dirt Bike and Dirt Rider magazine who still see the appeal, not to mention value of two-strokes, in what seems like a "four-stroke world".

For the review/test the Dirt Bike staff fitted up their in-house KTM 300 with the all-new VForce4. The KTM was previously equipped with a VForce3 making this an ideal test.

The unit took very little effort to install, and incredibly, it made for a vital power improvement. —Dirt Bike / June '11

To say the Dirt Bike staff was impressed with the new VForce4 would almost be an understatement. Not only was the Dirt Bike staff impressed with the VForce4, but they couldn't find a single negative to report in their experience with the VForce4. When asked to find a negative the staff reported a goose egg as you can see below

NEGATIVE: We searched and found a big, fat goose egg here. This system is excellent. —Dirt Bike / June '11
