Vehicle Information
Suzuki Quadracer 450 ATV (2006-2011)
The Suzuki Quadracer 450, also known as the LT-R450, was a high-performance, race-ready all-terrain vehicle produced by Suzuki from 2006 to 2011. It featured a fuel-injected 4-stroke DOHC single-cylinder engine with a displacement of 450 cc (449.8 cc). The 2006 model, in stock trim, produced approximately 40 horsepower. There were no distinct "trim levels" for the Quadracer 450 during this period; it was primarily offered as a single, race-focused model. The most significant mid-cycle update occurred with the 2008 model year, incorporating over 100 upgrades. The suspension, criticized as "painfully stiff" on the 2006 and 2007 models, was softened, significantly improving performance for recreational riders. This 2008 update also included a claimed 3 horsepower increase. FAQ:
