Yamaha YFZ450R MGC A-Arms from ATV Four Play
- Updated: March 22, 2010
ATV Four Play’s championship winning MGC A-arms are now available for the new Yamaha YFZ450R for both motocross and cross-country racers. The ATV Four Play MGC MX long-travel A-arms for the YFZ450R are a total of one inch wider than the stock arms. These aftermarket arms must be used with a 4:1 offset front wheel to abide by the 50-inch width rule enforced by the AMA and most other motocross sanctioning bodies. The motocross arms use the same length shock as the factory shocks, which measure in at approximately 18.5 inches, but the arms increase the YFZR’s wheel travel to 10.5 inches from the stock travel limit of 9.8 inches. The cross-country MGC A-arms from ATV Four Play are one inch narrower than stock and work with a standard travel shock setup.
Both sets of arms are camber and caster adjustable. In addition to increased adjustability, these new arms offer a smoother ride. Shock mounting locations on the ATV Four Play MGC arms have been changed from the stock YFZR mounting position in order to create a plusher ride. Color choices for the arms include red, gloss black, textured black, blue, yellow, pink and orange. Custom color options, including candy and chrome, are available at an additional cost. All ATV Four Play A-arms are TIG welded by trained, professional welders. State of the art welding fixtures ensure each arm is constructed within the same exact specifications to ease installation and guarantee a dependable, fast ride every time.
