Press Release –

The 20th Annual White Bros. 4-Stroke World MX Championships proved to be an ITP showcase as Kory Ellis, Josh Creamer and Dustin Nelson filled the top three podium positions after a long day on a tough track in San Bernardino, California.

Yoshimura’s Ellis made it a hat trick at this event, scoring his third straight 4-Stroke World MX title. The Suzuki rider, using ITP Holeshot MXR6 tires, dominated the 2007 race, which was run on the same Glen Helen Raceway course as the ATVA National held a month prior but was much rougher due to the hundreds of motorcycles also competing here over the weekend.

Ellis came from way back at the start of both 20-minute motos, and both times pulled away from the field to card a seemingly easy 1-1 moto tally for the overall victory.

Second overall on the day was Josh Creamer, putting in his best ride yet on the new Monster Energy Kawasaki KFX450R.

Creamer, on ITP Holeshot MXR6 tires, led portions of both motos while battling with Team Yamaha’s Dustin Nelson. The Team Green rider ended up with a 3-2 moto score for second overall, despite a leaky radiator hose in the second moto.

Nelson grabbed the first moto holeshot with his ITP Holeshot MXR6 tires (mounted on ITP T-9 Pro Series wheels) and was in the hunt in both races on his YFZ450.

At the checkers, 2-3 moto results would land him on the third step of the final overall podium.

So it was three different ATV brands in the top three finishing positions, but they had one big thing in common: they were all running on ITP.

Press Release –

Yoshimura R&D Of America, Inc. announced today the release of five new products for the new Kawasaki KFX450® R sport quad – Three New Exhaust Systems, a Yoshimura EMS Peripheral Interface Module (PIM) Fuel Injection Unit and FIMAK (Fuel Injection Map Adjuster Kit).

Yoshimura has been the leader as well as the pioneer in EFI (Electronic Fuel Injection). Expertise learned from years at the cutting edge of Superbike Racing has clearly put Yoshimura at the head of the pack when it comes to EFI tuning. The Yoshimura PIM and Ti- Pro Exhaust System equipped KFX450R takes the stock 36HP KFX up to an impressive 40.6HP. In addition, power delivery becomes much more linear and crisp.

“We’ve got a bit of an advantage for sure,” ATV Brand Manager Kory Ellis said. “Working with the Suzuki factory road racing team, we helped develop a lot of the technology used today. Also, for the last two years we have continually developed fuel injection adjusting devices for the Suzuki QuadRacer® R450 with a lot of success. Yoshimura has been working in this field since the beginning and we have a skill level that few can match.”

After any engine modification like switching from a stock exhaust pipe or after engine mods, you must re-map. The stock EFI has no idea what pipe is attached or what state of tune the engine is, it automatically defaults to stock parameters. The PIM units come with two preprogrammed maps for Yoshimura systems.

Yoshimura EMS Peripheral Interface Module (PIM):
For the 2008 Kawasaki KFX450R – #RF-432-2415 PIM $285.00 (MSRP)

The Yoshimura EMS (Engine Management System) was developed in AMA Superbike racing as a way to fine tune modified racing engine fuel injection mapping. As EFI technology has come to quad racing, the same technology that has helped Mat Mladin win six of the last seven Superbike titles and Doug Gust win last years WPSA Championship, is here for the KFX.

The #RF-432-2415 PIM is a piggyback unit that plugs in as an adjunct to the stock OEM wiring harness. This simple plug-in to the stock harness requires no major modifications; and takes about thirty minutes to install. The PIM comes with (2) pre-programmed fuel maps, which optimize fuel delivery for our Yoshimura exhaust systems. Map (a) offers best performance when utilizing the spark arrestor. Map (b) offers maximum machine performance with our race exhaust system. The PIM unit attaches directly on top of the OEM ECU and takes just a few minutes to install.

EMS Fuel Injection Map Adjuster Kit (FIMAK):
For the 2008 Kawasaki KFX450R – FIMAK #R-422 MSRP $275.00 (MSRP)

If additional fuel adjustments are required, the FIMAK is utilized when interfaced with the Peripheral Interface Module. The FIMAK is a hand held unit that makes mapping changes that ultimately effect fuel delivery. The FIMAK makes adjustments to the Yoshimura supplied base maps stored inside the PIM unit…or allow the user to make custom maps of his own choice/ Once adjustments are performed, the FIMAK is simply unplugged and stored in the racer’s toolbox.

The FIMAK will allow for +/- percentage adjustment of fuel, at various operating points. (throttle angle and engine rpm). The FIMAK has a total of 200 mapping points available. Throttle angle is well defined at the lower throttle angles, where engine response is critical. Engine rpm adjustment points are available in 500rpm increments. Fuel trim is adjustable in 1% increments, with a +/- 20% threshold.

Press Release –

The industry’s best kept… secret is now officially out: Chad “Wide-Open” Wienen has signed with Suzuki and will be racing the WPSA series and select GNC events on a Team Rockstar/MSR/Pro Taper/Suzuki/Yoshimura QuadRacer® R450.

The 22 year old from Galena, IL has been tearing up the tracks from Glen Helen to Oak Hill and that got the serious attention of the biggest factory effort in Pro ATV racing.

“We looked at how fast he was going as a privateer and wondered how fast could he really go if he had a full race-equipped QuadRacer under him,” Suzuki’s Rod Lopusnak said. “We know that Chad will be a great asset to the team. He really works hard, has a lot of talent and heart and deserves this opportunity. With the factory support behind him, who knows what this kid can do out there. We’re not just talking championships – we’re talking records.”

“I was so honored to be approached by the best team in the ATV industry and have this opportunity,” Wienen said. I’m just so proud to be a part of this team and to be riding with Doug and Dustin. Ryan Cox is the best mechanic out there and a good friend. I’m privileged to have him turn wrenches for me. Everything has already been clicking between us. I just know this is going to be awesome.”

Although Chad has been racing quads since he was 16, he has only raced pro since mid-season 2005. Last year was his first full race season and he podiumed at Budd’s Creek in the first moto. He decided to drop the GNC series and put in a full WPSA season, which he finished 6th overall.

So far, Chad has been practicing on a stock bike with a Yoshimura pipe and Fox Shocks. “I can’t believe the way this bike corners. It turns amazing compared to my old bike,” Chad explained. “This is just a stock bike with only a few mods, but I feel like I could win on it.”

And he probably could.

First race for the triple threat Suzuki powerhouse team will be the Opening Round of the WPSA SuperQuad Pro 450 event at the Silver Dollar Raceway in Reynolds, GA this upcoming weekend. The event will be broadcast on ESPN 2 on June 16th at 1:00 pm.
