Yamaha Adds Two New ATVs to Their Line
by Jason Giacchino
2012 YFZ450
Yamaha Motor Corp., U.S.A. is introducing a new YFZ450 with increased power and performance. The 2012 YFZ450 is priced at ,799 – approximately 0 less than the original YFZ in 2004 and more than ,200 less than the closest competing 450cc model – making it the most affordable high-performance 450 ATV on the market today.
The new YFZ features an updated 449cc liquid-cooled, double overhead cam four-stroke, five-valve engine featuring 95mm bore and 63.4mm stroke. Yamaha engineers significantly increased the low- and mid-range power (compared with the 2009 YFZ450 model) by revising the cam profile and timing and developing new ignition mapping. The new larger 42mm Mikuni BSR carburetor with throttle position sensor maintains the top-end performance while improving throttle response and significantly reducing throttle effort.
The YFZ’s power is complemented by its light weight, compact steel frame with aluminum sub frame and its proven handling characteristics. The new YFZ, ith its rigid cast aluminum swingarm and aluminum upper A-arms, helps keep weight down while maintaining performance.
The new KYB front shocks feature 9.1 inches of travel while the rear suspension system uses a piggyback Showa shock with 10.6 inches of travel. The new wheel was designed with the inner lip rolled in, increasing rigidity and allowing a reduction in weight while maintaining strength. And the new Dunlop tires (21x7R-10 in front and 20x10R-9 in back) were designed specifically for this YFZ. Twin hydraulic front brake calipers with 127mm discs and a hydraulic dual-piston caliper 173mm rear disc bring some serious stopping power.
The 2012 YFZ also has a ratchet-type five-speed transmission and heavy-duty clutch, adding to the machine’s improved comfort on long rides. The standard push-button electric start and Yamaha flip-style parking brake are added benefits. Its large capacity air box features no-tool access to the extra large oiled dual-foam filter for easy maintenance.
The new YFZ450 will start arriving at Yamaha dealers by the end of September. It launches into an immediate pool of parts and accessories – more than 90 GYTR items from Yamaha alone!
2012 Yamaha Grizzly 300
Yamaha has also announced the all-new Grizzly 300 2WD utility ATV combining best-in-class technology with a value price at ,099. This new light utility ATV has a smooth and powerful engine and is the only model in its class with a fully automatic dual range transmission.
The Grizzly 300 is powered by a 287cc single overhead cam four-stroke engine. Its class-exclusive liquid cooling provides precise temperature control and long engine life, even in extreme environments. At the center of its lightweight and durable chassis is a power plant with a 32mm carburetor that delivers smooth power.
Feature for feature, the Grizzly 300 easily outperforms any similarly priced competing model. The durable engine and dual range transmission offers Hi range for light duty and trail riding plus Low range for tougher chores and towing. This bear can pull more than 720 pounds and carry more than 140 combined pounds on the ATV’s front and rear racks. It features separate hydraulic front and rear disc brakes and 22-inch Maxxis tires with a rugged lug pattern for optimum traction and durability.
Creature comforts include a plush seat, push-button electronic start, water resistant under seat storage box, and large front and rear fenders with full floorboards for mud/splash protection. Under seat marine grade electrical components ensure protection from the elements, and the 2.8-gallon fuel tank provides ample range for chores or trail rides.
