Pitster Pro Mod Package can receive five different engines

ATV Four Play has launched its new Pitster Pro Mod Package, which alows parents whose children race ATVs in the youth classes to customize a national-level rolling chassis that is capable of receiving five different engine packages to compete in three separate youth classes in the AMA ATV national series.

ATV Four Play builds upon on the popular Pitster Pro quad as the base for the Pitster Mod. The long-travel ATV Four Play A-arms on the Pitster Mod are 2.235 inches wider on each side and are the first mini quad to accept Fox’s new Generation II Float X Evol front shocks. ATV Four Play adds its signature chromoly long-travel swingarm, which is two inches longer than the stock Pitster swingarm and allows for 10.5 inches of rear wheel travel with either a dual-rate Fox Podium X or Elka shock.

The stock Pitster chromoly frame is retained, but ATV Four Play adds up to 24 gussets to strengthen weak points while still maintaining the right amount of flex. The frame is adapted to fit the large radiator off Yamaha’s YFZ450 sport quad.

According to ATV Four Play, having five engines to choose from is what makes this youth race quad an affordable, long-lasting performance option for motocross families. ATV Four Play’s Pitster Mod’s has the capabilities of interchangeable engine mounts to accept engines from: Kawasaki’s two-stroke, 65cc KX65; KTM’s two-stroke, 65cc 65SX; Suzuki’s two-stroke, 85cc RM85; Honda’s two-stroke, 85cc CR85; and Honda’s new four-stroke, 150cc CRF150R.

Tom Skladzien, owner of ATV Four Play, says having the option to choose an engine lets parents keep the same long-travel chassis for several years and simply swap the engine out when its time for their racer to step up a class.

“The CVT class is great,” says Skladzien. “But the chassis is very expensive to make competitive and it is a frustrating class for most parents. There are so many variables with these machines. The clutching, building the engine, pipes, rollers, belts etc. Most of the time, as ‘mini quad parents’ we find ourselves not having as much fun as we should because these CVT’s demand a lot more maintenance and finesse than your typical Japanese shifter engines require. You buy these CVT quads for $1,700-$1,800 dollars and you find yourself putting $6,000 more into them. And at the end of the day, you’re still a CVT.”

Except for the CRF150R, Honda’s new high-tech mini dirt bike engine, all of the power plants available for the Pitster Mod have been winning races in dirt bikes for decades. The two-stroke engines are lighter, more competitive and have a broader availability of parts and modifications. The 65cc engines are competition legal for the AMA 70 mod class, the 85cc engines are legal for the AMA 90 mod class, and the 150cc four-stroke can compete in the AMA Super Mini class.

Customers have several options for ordering a Pitster Mod from ATV Four Play. You can buy a complete quad that is fully suspended with motor mounts of your choice but without the engine. Or customers can go “Ala Carte” and order a chassis with ATV Four Play suspension parts and then customize it with your choice of shocks, wheels and tires.

The Mod Racer Starter Kit includes the following options for $4,999: Pitster Pro chromoly chassis; spindles, hubs, braking systems, rotors, plastics, gas tank, stock axle and rear wheel hubs, rear sprocket with chain guard, ATV Four Play long-travel a-arms, swing arm and anti-vibe steering stem, 24 frame gussets, powder coated frame, motor mounts for customer engine choice and mounts for all electronics.

Currently, ATV Four Play is working with Hetrick Racing to develop a race-ready package for the KX65 engine and their exhaust. The Hetrick Racing packages may be available for the 2011 season. Fox and Elka are the current shock options for the Pitster Mods, but ATV Four Play may be able to accommodate another shock brand at a customer’s request.

The standard chassis and body components on the production Pitster Mod from ATV Four Play include: Tarantula Performance Racing’s new front bumper and Race Safer Pro nerf bars; ATV Four Play’s Generation II Soft Bars; ATV Four Play’s chain guide and chain slide; Streamline stainless steel brake lines; stock Pitster axle, axle carrier and brake plate.
