The 2027 Polaris RZR Pro R Boost introduces 275 turbocharged horsepower, broad low-rpm torque, expanded cooling, stronger clutching, and a reinforced driveline. DoubleZero Powersports examines the engineering behind Polaris's most powerful production RZR and what it could mean for racing and the UTV aftermarket.

Branden Sims wins Pro UTV Open at the 2026 SCORE Baja 500 in the Polaris RZR Pro R Factory, leading a Polaris podium sweep with Wayne Matlock second and Ethan Groom third. Brock Heger suffered a late-race front A-arm failure, and Can-Am's Kaden Wells took Pro UTV Forced Induction in the Maverick R.

The 2026 Silver State 300 delivered one of the closest UTV races of the season as Kyle Chaney secured the official overall victory in his Can-Am Maverick R after a dramatic post-race penalty reshuffled the final order.
