The decision to enter the four-stroke market was not taken lightly. It was immediately clear that as a company, Moto Tassinari wanted to continue to build on the success of the VForce3 reed valve system. They wanted to offer a product to the racing community that they would in turn feel was an essential part of their engine performance and on-track success. Much like the VForce3 reed valve system has been previously.

They knew right from the beginning they did not want to jump on the proverbial band wagon and rush to offer a product where the performance benefit is often questionable and marginal at best. Instead they wanted to again enjoy the satisfaction of being chosen by every Factory race team as mandatory equipment for racing at the highest level. They chose to build on their vast knowledge of air intake and began work on developing the AIR4ORCE in the summer of 2008. When initial dyno and field testing showed impressive results, development was kicked into overdrive. By mid-summer of 2010 they had actual production samples that were ready for the ultimate test: the outdoor nationals. Matt Jory of the Troy Lee Designs / Lucas Oil / Honda race team was one of the first to gain access to the AIR4ORCE intake system. With Matt's knowledge in four-stroke engine technology he immediately understood the benefits of being able to swap out velocity stacks as well as increasing the air volume of the boot. The Troy Lee Designs / Lucas Oil / Honda race team began using the AIR4ORCE immediately and raced the last three motocross nationals of 2010 with the AIR4ORCE intake in all their Honda CRF250R's, including Tarah Geiger.

Since then several more teams and riders have been added to the AIR4ORCE equipped roster, such as... Factory Honda, GEICO / Honda, Troy Lee Designs / Lucas Oil / Honda, DNA / Shred Stix / Yamaha, Rockstar Suzuki Lites team, ARMA/Suzuki City's Malcom Stewart, Matt Lemoine, Nico Izzi, Darryn Durham, BikeIt Cosworth Yamaha GP team, Yamaha Gariboldi Monster Energy GP team, Ashley Fiolek, Tarah Geiger, Jessica Patterson, and more. The AIR4ORCE has also already chalked up several wins in the 2011 season with riders like Cole Seely, Eli Tomac, Ryan Sipes and Justin Barcia, Zach Osborne and Arnaud Tonus.

Specs:
