MRP Suspension Services

Kenny Martin and Ian Tetrick talking suspension setup trackside

Our suspension service department is headed up and directed by Kenny Martin. A former road-racer with a 2001 WERA National Endurance Championship title, brings his extensive knowledge of suspension dynamics, bike setup, geometry, and knowledge of available products to MRP's customers. Kenny has over 14 years of experience setting up bikes for racers and street riders using a wide variety of suspension products. He is constantly evaluating new products and configurations, and works closely with riders of all skill levels to discover optimal setups and implement improvements.
Having a proper suspension setup provides advantages to both street riders and dedicated racers; street riders will experience better handling and a more comfortable ride, while racers know that suspension setup is a critical key to unlocking faster laptimes at a race track. MRP Motorsports specializes in motorcycle suspension service and tuning, with a long history of satisfied customers and race wins.
