Inferno™ grips are made from durable TPR rubber for excellent grip and vibration dampening while maximizing heat transfer to your hands. Standard room temperature operation produces up to 170°F, allowing you to find the perfect level of heat. The multiple textures and patterns of the rubber create a feeling of comfort with a fresh style. The included E-Z™ temperature controller is simple to use while offering the highest functionality on the market. The single button controller has 5 preset heat settings with each press of the button. Smart logic design turns off heat if battery voltage drops below 12.5 volts. This technology has proven itself in our product lines for more than 10 years. These grips were designed specifically for the Ryker and include an exclusive throttle sleeve to retain the confidence of factory performance. Easy installation requires no specialized tools. Make those cold weather rides a whole lot more fun with Inferno™ grips!
