Choose from 15% or 30% gear reductions and cast or billet aluminum housings so you can optimize for the kind of riding that you actually do. You can get a 30% gear reduction for big tires and challenging rides or a punchy 15% gear reduction for fast trails. Plus, you can upgrade to a stronger portal by opting for the dual idler configuration. Whatever you choose, GDP’s Yamaha Viking portals will give you industry-leading performance on every ride.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat Is a Dual Idler®?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAfter years of research and development, the dual idler gear portals use a second idler gear in the portal box to spread the load over twice as much surface area for more reliable torque transfer and a stronger gear set. Precision CNC grinding helps ensure the gears are properly mated, and the gears are made from 9310 steel alloy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePerfect for All Kinds of Rides\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhether you like rocks, trails, mud, or doing a good day’s work, a Yamaha Viking portal gear lift makes it better.
