I raced one today...
2008 XP "X" with 235mi 1.25 Ripsaw No studs VS. my 2007 Attak with 73mi 1.25 Ice Ripper
condition, very loose hardpack lake
Front the start the XP jumped a half a sled ahead, then the midrange of my ATtack just came on strong and passed him fast to jump a half infront of him....then i very slowly creaped away from him upto my top speed of 113mph on the dreameter.
I've read here she going to only get faster as I put some more hard miles on it.
