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.

Transworld Motocross magazine test rider rings out the '13 YZ125 and comes back smiling

Recently the guys over at Transworld Motocross magazine threw a leg over the 2013 Yamaha YZ125 and were grinning ear-to-ear. Hear their opinions (and the sweet sound of a 125cc being wrung out) on why the 125cc two-stroke still has a place in the sport of modern Motocross, and also hear their impressions of the performance gains with the addition of a Moto Tassinari VForce3 reed valve system. Here's a hint, "…man what a difference that made…a lot crisper…also added a ton of over rev…I was able to do jumps later in the day with the VForce reed block on that I couldn't do earlier when it was stock…", and more.

AIR4ORCE tunable intake rated "Well worth the money" in July issue of Transworld Motocross

The Moto Tassinari AIR4ORCE tunable intake system for the Kawasaki KX450F was reviewed quite favorably in the July issue of Transworld Motocross magazine. The reviewers found the AIR4ORCE tunable intake system to do just as claimed, saying…

Zach Osborne of the Monster Energy Yamaha GP team and his AIR4ORCE equipped YZ250F

Moto Tassinari has been sponsoring Steve Dixon and his team (currently Monster Energy Yamaha) with the AIR4ORCE intake system for their Yamaha YZ250Fs for past two seasons. With the addition of US based rider, Zach Osborne the team has quite a following on both sides of the pond. It was a pleasure to see Zach Osborne come over and race the first four rounds of the 2012 Supercross series in the Lites West Coast division before he completes his final season in the MX2 class. Zach Osborne hopes to come back to America and race full-time beginning with the 2013 season.

Unfortunately Zach just had a recent get-off that has left him with a list of injuries that will see him miss the opening round of the upcoming GP season. Here's wishing Zach a quick and full recovery. At least in the meantime he can admire the cover of issue 78 of MOTO UK magazine.
