Suzuki Motor Suzuki LT-R450

The Suzuki LT-R450 Quadracer was an all-terrain vehicle produced by Suzuki between 2006 and 2012. Intended as a race-ready ATV, the LT-R450 was developed with the help of WPSA ATV champion Doug Gust, and featured a fuel-injected 450 cc (27.46 cu in) 4-stroke DOHC single cylinder engine, based on the powerplant found in the RM-Z450 racer. The 2008 model was a significant update over the 2007 model, with a claimed power increase of 3 hp (2 kW) as well as over 100 upgrades. In 2009, Suzuki stopped importing the LT-R450 into the United States, after 25,396 units had been sold. As a result of emissions control breaches on both the LT-R450 and the RMX450Z, the EPA fined Suzuki US$885,000.
