Polaris racer RJ Anderson took on the iconic Mammoth Motocross track in his new Turbo R! If you’re not familiar with Mammoth Motocross, this is the oldest continuous running motocross race in the USA starting in 1968. Due to the weather, fire hazards and California permits, the track is closed year-round but opens like clockwork each summer for 10 days of racing. Following this year’s event, RJ charged the track in his Turbo R, making it the first time any 4-wheel vehicle has been allowed on the mountain. RJ Anderson is an accomplished off-road racer with years of experience, multiple Off-Road Championships and hundreds of career podiums. Enjoy as RJ takes his all-new @Polaris RZR  Turbo R through the legendary Motocross track, becoming the first UTV to track the iconic course.
