Suzuki Off Road ATV Flash Review: Suzuki ATV engineers continue to refine the QuadRacer R450 to be faster, lighter and easier-to-ride each year. And for 2009 Suzuki certainly delivered a more refined QuadRacer R450. But things weren’t always this way. Flashback a few years and you might remember that the current level of “race-ready“ off road atv didn’t even exist. Then, successfully navigating the motocross track required a thick wad of cash for a new moto machine, followed up by another stack of bills for hop-up components such as wider A-arms, axle, and sturdier shocks. Only then would moto racers be able to run around at the racetrack without worrying about hurting themselves. All of this changed when Suzuki ATV engineers released the QuadRacer as an all-new model in 2006. With the introduction, a new category of Off Road ATV was born. Last year, engineers injected the LT-R with a host of changes that are aimed at getting moto racers around the track faster and more comfortably than ever. Improvements in upgraded powertrain and friendly, ultra-stable chassis are impressive. With the latest rendition, performance has been enhanced further. The changes aren’t drastic, but enable atv riders a more comfortable ride. A new aluminum subframe replaces the steel piece and brings the machine’s weight down to 414 pounds ready-to-ride. Grips swiped off of an RM-Z450 moto bike provide more comfort for your hands. In the tire department, new Dunlop KT382 rubber with a revised tread pattern grace the 10-inch front aluminum wheels, while out back the same Dunlop KT388s are used. Lastly, engineers added an additional clutch spring that’s said to enhance clutch durability. Between those magnesium covers, a forged aluminum piston slides inside the aluminum electroplated cylinder, gobbling up 450cc of displacement. Lightweight titanium valves controlled by dual overhead camshafts allow the Suzuki moto engine to rev out high yet spool up quickly. Electronic fuel-injection with a 42mm throttle body and multi-hole injector ensures a smooth, steady stream of power when your thumb demands it. A five-speed transmission and cable-actuated clutch allow you to manipulate power production. The QuadRacer’s chassis is comprised of a sturdy steel frame and swingarm designed to carry the moto machine’s mass low and centered. Up front, independent double-wishbone suspension give the R450 Suzuki ATV a wide 49-inch stance. Wheelbase comes in at 50.6-inches. A pair of remote reservoir-equipped Kayaba shocks featuring 40mm pistons and 4-way adjustability (preload, high/low-speed compression and rebound damping) absorb the rough stuff. Similar spec Kayaba shocks are used out back, however, they utilize larger 50mm diameter pistons. All three shocks benefit from a slick Kashima coating for reduced stiction and improved response. As for stopping, a pair of 160mm brake rotors pinched by twin-piston calipers is used up front while a solo 190mm rotor and caliper keep the atvs rear wheels in check. Rubber brake lines complete the setup. So is the Suzuki ATV LT-R450 truly ready for atv quad racing? By simply removing one bolt you can pull out the front headlight and slide in a number-plate-shod nosepiece. Throw on some nerf bars, wire up a kill-switch, and you’re ready to line up against other moto racers at the gate. It’s that simple. Check Out Suzuki Dirt Bikes.
