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
Cosworth Yamahas Profiled in MOTO UK Magazine
Steve Dixon of the Bike It Cosworth Yamaha Wild Wolf GP race team definitely knows a thing or two about bike set-up and getting the absolute maximum performance from his race bikes. Before Steve Dixon was the owner of the Bike It Cosworth Yamaha Wild Wolf GP race team he was long-time GP mechanic. So it really comes as no surprise that team members Zach Osborne and Arnaud Tonus have some of the most trick bikes in the paddock.
The new AIR4ORCE airboot and intake we're running has helped us here. It made a noticeable improvement right away, —Steve Dixon BikeIt Cosworth Yamaha Principal
For 2011 the Bike It Cosworth Yamaha Wild Wolf MX2 racers will be AIR4ORCE equipped. As of this writing, Zach Osborne is sitting atop the leader board after four rounds of the Maxxis British Championship series. Zach finished fourth at the recent USGP at Glen Helen and then followed that up with a solid 5th place at the Grand Prix of Brazil a week later.
Dirt Rider's Pete Peterson on the AIR4ORCE
In the June issue of Dirt Rider magazine, Pete Peterson takes a shot at "fixing the 2011 Honda CRF250R to suit his personal tastes and riding preferences. In his quest for the elusive "three-stroke" the first modification done by Pete is the installation of the Moto Tassinari AIR4ORCE tunable intake system.
Pete also puts to rest any fears about a complex installation by adding, "Swapping stacks is simple, as is getting the new AIR4ORCE on…". Notice Pete didn't find a need to remove the rear shock as some reviewers have mentioned previously. Worth pointing out, is that we've never had to remove a shock on any model motorcycle we have installed an AIR4ORCE on while developing and testing the AIR4ORCE.
The short velocity stack took Honda a step closer toward that two-stroke feeling by freeing up the motor to rev quicker. —Dirt Rider / June '11
Rich Simmons explains the AIR4ORCE benefits
The Troy Lee Designs/Lucas Oil/Honda team was the first Pro team to race with the AIR4ORCE tunable intake system. Their already potent Pro Circuit tuned motors were AIR4ORCE equipped for the last three MX Nationals of the 2010 season. So who better to describe the benefits than Troy Lee Designs/Lucas Oil/Honda team mechanic, Rich Simmons. Rich is the tuner for two-time 2011 Supercross Lites winner, Cole Seely.
We run the Moto Tassinari airboot (AIR4ORCE) and it works really well. —Rich Simmons
