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 our dual idler configuration. Whatever you choose, GDP’s Yamaha Viking portals will give you industry-leading performance on every ride.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat Is a Dual Idler  \u003c\/strong\u003e\u003cbr\u003ePerfection takes time. After years of research and development, we’ve made our dual idler gear portals unlike any other. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don’t do a thing if they’re not mated perfectly, though. Precision CNC grinding ensures ours do. Our gears are made from the industry’s toughest 9310 steel alloy. Didn’t think dual idlers mattered  With GDP’s quality and experience, they finally do.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect for All Kinds of Rides\u003c\/strong\u003e\u003cbr\u003eWhether you like rocks, trails, mud, or doing a good day’s work, a Yamaha Viking portal gear lift makes it better. A 30% gear reduction gives you plenty of punchy torque to turn big tires through mud or over rocks. A 15% gear reduction still boosts your torque a ton while preserving your top-end speed for trails and road riding. No matter what you’re doing, there’s a GDP Portal setup that can help.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA Gear Reduction That Protects Your Drivetrain\u003c\/strong\u003e\u003cbr\u003eBecause our Yamaha Viking Portals put the gear reduction directly in the hub, your entire drivetrain benefits.
