The Polaris RIOT 120 Sport is a popular snow bike conversion system manufactured by Timbersled, a Polaris-owned brand, designed to convert a dirt bike for use on snow. It is not a standalone snowmobile but a track and ski kit. The Timbersled RIOT 120 Sport is specifically designed to emulate the agile feel and performance of riding a dirt bike on snow. Track: The kit features a 120 x 11.5 x 2.5 inch Traverse track with added porting to make it lighter and more playful. Suspension: It uses the RIOT single-arm rear suspension system with Timbersled IFP coilover shocks for durable and consistent performance. The suspension is highly adjustable, allowing riders to switch between a "wheelie mode" for playfulness and a "climbing mode" for deep snow ascents. Chassis: The frame and rails are made of aerospace-grade, high-strength aluminum for a strong yet lightweight structure. Braking: The system comes with a factory pre-bled brake system, designed to prevent ice and debris buildup.
