Went out for a good rip today. Was riding with a few friends, 08 xfire800, 05 mach z 1000, 99 mxz 670ho . Had to start with a quick race to start off the ride. Lined up with the mach and a f1000 with a 1200 kit on it. very impressive power out of the xfire. i only hade 24 miles on my machine and i weigh about 300lbs with all the gear. buddies mach is ported and polished and he weighs around 150lb. Same with the f10, small guy big hp. I got a good hole shot, at 300ft the mach caught me and we stayed pretty much even for the 660. I don't know about the f10, we both seemed to have him in the 660 but that thing turned on huge at the 600ft mark, Pulling away from us with authority. Anyways i was really impressed with the new 1000, power is awesome ride is very good.The only thing i didn't like is the fuel mileage. It burnt about 3/4 of a tank and the doo was just over a quater. i realize. it has to break in. Any ways just wanted to share my story with the world.
