MaxPower and RPMs have merged to become MaxPower-RPMs.
This combines MaxPower's Quad Racing and Cylinder Replating experience with Rick Peterson's engine design and Motocross industry background.
Here is a brief history of each company.
MaxPower opened in Madison, Wisconsin in 1997. MaxPower originally specialized in plating cylinders, and also building Big Bore kits for Motocross bikes and ATV's. The Quad enthusiasts on MaxPower's staff have taken the MaxPower 4-stroke ATV kits to the highest level possible using the cast OEM cylinders.
Rick Peterson began building Big Bore and Stroker Jet Skis in the mid 80's. In 1994, he built the first YZ167. Cycle News tested it and liked it so much they put it on the cover. The kits began out-selling the Big Bore Jet Skis, so Rick began building them full time. He bought Nikasil-USA in 1997 and his staff of 12 began plating cylinders in-house, as well as stroking and balancing cranks, porting cylinders and testing all promising performance parts on the dyno and the track.
When factory Honda, Kawasaki, Suzuki, TM, and Yamaha wanted wild porting that required welding up ports before replating or wanted Super-Minis built, they turned to Rick Peterson. RPMs plated over 30 cylinders for James Stewart's KX125's, and also built Super-Mini's for James as well as Chris Gosselaar, Sean Collier, Kyle Partridge, Bobby Kinnery, Zach Osborne, and many more of today's Motocross stars.
In 2002, Rick built the first YZ302F. Dirt Bike called it "a great Vet Machine. Truly impressive. TWMX rated the YZ302F a "10" and called it, "The funnest Bike of all time." Rick agreed, and was hooked on the Big Bore 250F's. Soon YZ302F sales eclipsed 2-stroke kit sales. But the stock cylinders were cast aluminum and Rick found that the 4-strokes could only be bored 2mm or durability suffered. Modern-Day cast 4-stroke cylinders are just not very rigid. Because modern 4-strokes have such short strokes, stroking the crank greatly improves power, but Rick was still determined to find a way to run a larger bore without compromising durability.
In 2004, Rick built the first ICE CUBE cylinders. This was no small feat. It required the purchase of over $100,000.00 of CNC equipment and many late nights! The ICE CUBE was a work of art. (Ok, maybe not the first one!) It is billet aluminum with a nikasil plated liner that allowed Rick to build Big Bore Kits that are more durable than cast cylinders. And pretty cool looking, too; if you don't mind us saying..........
The popularity of the ICE CUBE prepared RPMs to step to the next level.
Half-way across America, the billet aluminum ICE CUBE was just what MaxPower needed to develop our ATV kits to a level beyond anything possible with cast cylinders.
Rick quickly realized that the demand for the ICE CUBE was much greater than his staff could handle. He needed to "call in some help" from MaxPower to expand into the world market.
In November-2004 MaxPower moved the RPMs line of 2-stroke kits to Madison, Wisconsin. The RPMs staff in Ontario, Ca. began the design of the YFZ488 and YFZ523 ICE CUBE.
Over the next 7 months Rick Peterson trained the MaxPower staff on his kit specifications and on his trade secrets for developing future kits to the highest standards in the industry.
In June-2005, MaxPower completed the purchase of RPMs 4-stroke line and moved all of the 4-stroke parts to Madison, Wisconsin.
The combination of the two companies allows MaxRPMs to develop dyno and race-proven combinations much faster than our 2 companies could do before. It took RPMs over a year to develop the first ICE CUBE, now it takes under 3 months to bring a new ICE CUBE from the CAD program to the dyno!
On that note........ICE CUBES are more expensive to manufacture than cast aluminum cylinders, but they are much stronger, way cooler looking and can be brought to market much faster. In the 12-18 months it takes to have a cast aluminum cylinder ready, let-alone tested, you'd be on next-year's bike, right? The ICE CUBE will continue to be the first cylinder available for new models and we will have months of testing under our belts before any cast cylinder can reach the prototype stage.
The main facility in Madison, Wisconsin does all of the cylinder plating, motor assembly and parts sales for every kit that MaxPower or Rick Peterson Motor Sports (RPMs) has ever sold.
We're sure you'll see that the combination of MaxPower's production capabilities and Rick Peterson's ingenuity and industry contacts set the MaxRPMs kits and customer service as the highest standard in the Motocross and ATV industry.
