Mark divulges all the details you need to know about the design and development of Polaris’ all-new 850cc 2-stroke Patriot engine.
Following a Turbo Comparison and 800-Class Shootout earlier in the season, we line up the top contenders in the 2019 600 2-stroke snowmobile class and do a shootout between Ski-Doo’s MXZ 600R, Arctic Cat’s ZR 6000 and Polaris’ 600 INDY XC.
After getting a behind the scenes look at how MBRP designs and develops exhausts at their test facility, AJ installs the all-new Trail and Race versions of MBRP POWERSPORTS 850 Patriot exhausts onto our Polaris XCR 850 and evaluates the performance gains you can expect to receive.
And then AJ hammers down on the 160-hp, 2019 Arctic Cat ZR 8000 RR 137 as he rediscovers the true potential of this race-ready sled.
