i think its funny how people talk about the can-am 800 but it was can-am themselves that put a 800cc limit on the Utility Mod and Utility "Unlimited" class in the GNCC series. I think they were scared of the modded v-twins from another particular company

whats even more ironic is that can-am motor was really an a 806cc which is over there imposed rule, but the way it will go down is they will give them the 1% so they can run. Its funny that little after market companies can put the fear in to the MFG's.
if you do the formula it comes to 806.48cc. Now I know they round up as there parts list shows a 90.958 piston. But even that comes to 805.73cc. But they don't give the actual stroke number. But rule of thumb is, if over .5 you round up. So if the stroke is like 61.5 with a 90.958 piston, then they would have 799.24 cc. So they still could be under 800cc if we knew the exact stroke. The 800 was taken from there 400 and made a twin out of it, and the 400 shows a 61.5 stroke, thus that would make the 800 just under 800cc.
Really I am poking fun at Can-Am for going and getting the rules changed to 800cc when their motor is a 806. That was funny! Now it makes them look stupid because they had to go back and make it a 840 class.I don't know why they would even do this but it doesn't matter to me.
cc's are way overrated, the manufacturers could build a 500 that would cream anything on the 4x4 market but the manufacturers are in a cc war and everyone wants something bigger than their buddy, not everyone realizes how detuned some of these motors are.
i was anxious to see the 09 Polaris lineup, i didn't get my redesigned scrambler/ renegade competitor but its a step forward and i believe they set the bar high after none of the other mfg's did anything exciting to their line ups in 09...well artic cat had a couple neat things... it wont be long and dual a-arms and power steering will be standard on all makes and models.
