Viper Motorcycle Company Receives the First Ilmor Designed 152 Inch Production Engines

HOPKINS, MN – May 5, 2010 – (Motor Sports Newswire) – Viper Motorcycle Company (OTCC: VPWI.OB), a wholly owned subsidiary of Viper Powersports Inc., announced today delivery of the first re-designed production short stroke engines for the 2011 Viper build.

According to Terry Nesbitt, President, Viper Motorcycle Company, “The new engines are incredible. All engines and drive case parts are CNC machined from 6061 aluminum billet alloy. Each component piece is then hand polished by American craftsman prior to assembly. The 152 is the largest and most powerful air/oil cooled production v-twin available. In addition to overall increased performance, the new engine produces considerably less vibration and runs cooler due to the improved oil flow throughout the engine via an Ilmor designed twin scavenge dry-sump oiling system. Peak torque is an industry first massive 153 foot pounds”.

Paul Ray, President, Ilmor Engineering Inc., stated, “We have hundreds of hours of dyno testing resulting in a powerful, dependable, EPA certified high mileage engine. This is a Viper proprietary engine with state-of the-art technology. The Ilmor air/oil dry-sump scavenge system utilizes 3 oil pump stages. The first stage is for oil feed with twin stages for independent drainage of the heads and crankcase, greatly improving overall oil flow. Our unique system provides much needed cooling to the cylinder heads, well beyond conventional air cooling resulting in greater reliability. The Viper/Ilmor crankshaft uses an oversize crank pin for durability and has a unique balance formula to dramatically reduce vibration levels”.

Nesbitt continues, “We are extremely excited at this mutual opportunity. Our Joint Venture relationship with Ilmor will enable us to continue moving forward as an OEM providing a unique proprietary product designed and manufactured by Viper/Ilmor.  The 2011 Diamondback 152 is scheduled for shipment in May while our second model, the Mamba is scheduled for later introduction this summer and will also be powered by the all new Ilmor 152. With an industry first chassis and the incredible Ilmor engine, we expect our sales will continue to grow resulting in enhanced brand value and visibility. We will also continue to increase our brand visibility through cross-marketing activities with Ilmor Engineering Inc”.
