I came on the Poo side for the first time to ask this same thing!
Getting a Pro 800 for me, and am thinking of getting a 600 for the wifey. But need to decide on warranties. The 2yr with $600 back makes it easier to swallow buying the wife a new sled that will rarely get ridden. (A backup for me realistically.)
I talked to a bud today who kinda explained that the warranties are limited, based on the value of the sled and that after a while, you can run out of coverage. (He is $1300 away from no warranty on his Dragon, even though he has time left.)
So with the 600 engine, seems like 2 yr would be the way to go? Cannot decide on the 800. Need to talk to dealer I guess, to get the specifics.
