Introduced for the 2009 model year, this mid-displacement utility ATV was Yamaha’s answer for riders who wanted much of the larger flagship’s character in a more manageable package. It sat between the brand’s larger utility machines and smaller entry-level models, carrying the Grizzly nameplate into a new middleweight role and broadening the line for trail use, hunting, and general work duties. Yamaha positioned it as a versatile machine with the rugged, heavy-duty look and utility focus associated with the Grizzly family, while emphasizing easier handling than the larger flagship version.
The model appeared in Yamaha’s lineup beginning with the 2009 model year and remained part of the Grizzly utility range through the 2014 model year. In Yamaha’s own materials, it was described as a key utility offering alongside the larger Grizzly variant, and it was shown in the company’s product history and annual reference materials as a representative ATV for the brand. During its run, Yamaha offered it in multiple configurations, including versions with and without electric power steering in some markets, but the core nameplate stayed consistent.
Historically, the Grizzly 550 is significant as one of the most recognizable Yamaha utility ATVs of its era: not a pure performance machine, but a capable, do-it-all work-and-trail platform that helped define the company’s ATV identity in the late 2000s and early 2010s. The nameplate ended after 2014, and Yamaha later moved its North American utility ATV lineup toward the redesigned Grizzly 700 and the Kodiak 700, leaving the 550 as a distinct, discontinued chapter in the Grizzly story.
