Early morning ride at DUNEFEST 2011

Gotta love the thick cool air at the coast ! The Brute Force was making sick power ! Pulling the front end is more impressive when people realize you are not running paddles or 4x4. Many thanks to MUZZYS , The Motoshop , Stuck on Racing Graphics , GoPro Hero HD , Troy Lee Designs.

MUZZYS RZR900XP

     We had the chance to test a new RZR900XP in stock trim and than install a MUZZYS exhaust system and DigiTune, and retest.

     The RZR900XP is a pretty impressive machine in stock trim and kudos to POLARIS for building it. The pure grunt this thing displays in stock trim is very impressive, it pulls hard all the way to the top, it handles better than any other stock machine I have driven, and is a very capable dune machine, with the exception of the stock XP tires (which are horrible, don't fret though as the new models are going back to the BIGHORN's). POLARIS put together a nice performing, powerful yet mild mannered UTV, and did a great job, and judging by all the 900XP's at DUNEFEST 2011, the enthusiasts are snapping them up.

     We ran the 900XP (supplied by Polaris of Portland, thanks Casey,) in stock trim and than installed the MUZZYS performance complete exhaust system and DigiTune Pro. WOW ! WOW! WOW!  The sound when we fired it up let us know we had unleashed a monster ! Without being so loud you couldn't talk over it,  The deep rumble at idle and sweet tone at rpm is enough to make any motorhead start to sweat and quiver. As we backed out to head out into the dunes you could immediately notice the snap the system had added. The throttle response was much quicker and much more aggressive. After a couple runs to dial in the DigiTuner, we went for it ! A simple snap of the throttle let us know this was nowhere near the same machine and the roll on throttle response was immediate, even at 45mph it would set your helmet into the headrest. 

     The overall acceleration and snap was very noticeable in every situation, and really impressive running the rollers at speed, it would blow the tires off every time the suspension was unloaded.

     The team at MUZZYS has done a great job on the POLARIS RZR900XP system and DigiTune Pro. The system is easy to install, looks awesome, sounds even better, and makes a huge difference in performance.

     Many, many thanks to Polaris of Portland and Muzzys Performance for allowing us test the RZR900XP and the MUZZYS system and DigiTune, What a combo ! When I close my eyes I can still hear the sweet rumble...
