The KTM 890 ADVENTURE R ‘s spoked 21-inch front and 18-inch rear wheels are specifically developed to handle hardcore offroad exploration. Fitted with Metzeler KAROO™ 3 adventure tires, the wheels are heavy-duty, lightweight and feature new anodized hubs (instead of powder-coated). With decades of experience and success in the toughest offroad and rally raid events, you can charge off into the most remote wilderness with full confidence. The standard wheels are tubeless – with the option of a Tire Pressure Monitoring System. For the most extreme riding, optional KTM PowerParts wheels are available which are slightly narrower and closer to enduro competition wheels – which allow for the hardest of hardcore riders to fit mousses.
