XR vs Nytro: Same HP, better torque and Powerband curves, 11 lbs lighter (no big deal in a trail sled), now time to get it dailed in. Remember BRP in in business to sell sleds and there has been a market for 4s sleds so it only make business sense to go after it. It isn't an ego battle about 2s vs 4s. I'm looking forward to an 800etec in a Summit XP. Until then I'll just keep ripping on my 06 Summit X and 08 XP.
its alittle more then 11 pounds diff. 509 is a lot lighter then 582, i hope they do it in a summit that will be my choice for 2010 anybody know how long this engine has been around or what its been put in before, or is it totally new
