For mountain riders, Polaris is introducing the new Patriot 9R engine – a radical, naturally aspirated big-bore that Polaris officials say creates 7 percent more power and 12 percent more torque than the Patriot 850 on which it is based. It’ll be available in select RKM Khaos and Pro RMK packages for those who order in the spring and offers a slightly different ride experience than the also up-power Patriot Boost.
