This past Sunday we went on a Poker run put on by the Horseheads Snowmobile Club and during the course of the event we came out onto a small lake. There was a guy there with a RX-1 and my brother had let someone borrow his 02 ZR 800. It has twin pipes, v-force reeds, and a clutch kit. They ran across the lake and back and both times the ZR 800 beat the RX-1 by at least 10 lengths. The Yamaha never seemed to make any ground on the ZR after the take off. I was expecting the big 4 cylinder to stretch its legs across the lake but it never seemed to be able to reel the 800 in. The ZR was pulling pretty good!!
