Polaris and RZR Factory Racing have introduced the all-new, purpose-built RZR Pro R Factory Boost platform for open-desert racing.

Delivering up to 400 hp, the RZR Pro R Factory Boost is designed and developed by Polaris engineers and built in Roseau, Minnesota, bringing a bigger, stronger and more capable package to the race-proven platform, according to the manufacturer. The model joins the existing Gen 2 RZR Pro R Factory in Polaris's race vehicle lineup.

The RZR Pro R Factory Boost builds on the recently introduced production RZR Pro R Boost while incorporating proven components and lessons learned from the Gen 2 RZR Pro R Factory. Engineered specifically for competition, the new race machine further refines power delivery, chassis design, cooling and suspension to meet the demands of high-speed desert racing, according to Polaris.

The RZR Pro R Factory Boost includes the following race modifications:

• Turbocharged Power: A race-tuned, turbocharged ProStar Fury 2.0L four-cylinder engine delivers up to 400 hp for commanding holeshots, high-speed passes and the power to attack demanding terrain.
• Performance Race-Spec Chassis: The reinforced chassis features a wheelbase extended by 6.5 in. to a total of 111 in., for greater straight-line stability and control over rough terrain. Increased tubing size across key structural members adds strength and stiffness to support higher speeds and the demands of desert racing.
• Competition-Ready Cockpit and Cage: Redesigned with driver feedback in mind, the all-new cage design delivers added strength, while a cab that’s two inches wider provides more cockpit space for improved comfort and legroom. The expanded design transforms the feel from a traditional side-by-side to a purpose-built race car.
• Full Carbon Fiber Bodywork with Aerodynamic Design: Sculpted carbon fiber bodywork and an arched roofline reduce weight and improve aerodynamic efficiency at high speeds. Polaris engineers used computational fluid dynamics (CFD) to model airflow at speeds exceeding 100 mph, informing the cage shape and redesigned rear body profile to optimize airflow and support high-speed desert racing performance.
• Upgraded Fuel System: A 45-gallon (170-L) fuel cell increases capacity over the previous-generation RZR Pro R Factory’s 34-gallon system, extending its range beyond 200 miles to reduce pit stops.
• MoTeC Components: The fully integrated MoTeC electronics package features an upgraded M150 ECU and dual power distribution modules, adding a second PDM over the Gen 2 RZR Pro R Factory for expanded power distribution and control capabilities.
• Race-Tuned DYNAMIX DV Suspension: Three-inch internal bypass DYNAMIX DV Live Valve shocks feature race-specific components and upgraded one-inch shock shafts for increased strength and a broader dynamic range. Race-specific tuning maintains control across changing terrain, while a standard FOX steering damper absorbs large impacts to improve steering control and driver confidence at high speeds.

The RZR Pro R Factory Boost is available to order now in limited quantities through SCI Distribution, LLC, an exclusive distributor, with the first order window closing February 15, 2027. The new race machine will be offered alongside the continued availability of the RZR Pro R Factory, giving racers two platforms to choose from based on their performance needs and racing goals. Polaris will produce the RZR Pro R Factory Boost with SCI managing the sales and post-sale customer support process.
