On the other hand, the 800 Cleanfire mill of the Polaris 800 Rush Pro-R has been significantly revised to improve durability while reducing oil consumption, emissions and smells. Moreover, the mechanical oil pump (controlled by a rod instead of a wire) lubricates the internal components with greater precision.

In both cases, power is managed by the excellent CVT P2 system with variable-diameter pulley, also offering greater precision than ever. The unit's improvements help reduce the operating temperature and increase belt longevity as well.

Bottom line
The 2011 Polaris 600 Rush Pro-R and 800 Rush Pro-R now have all the tools to satisfy sporty trail riding enthusiasts. The superior dynamics of the Pro-Ride chassis (compared with the previous architecture) essentially turn them into thrill-inducing machines. The brand is certainly back in the race and we haven't seen everything yet. Stay tuned!
