Want speed......"that is the fastest thing on wheels I've ever been on", that's the quote from Rob at Hot Seat (he has since moved on to a magazine gig). That comment is from a custom quad sitting in the shop at Hot Seat. At the time I looked it over, it had a 600cc twin sled motor. It is capable of a 440, or a 700, but the 600 already ate sprockets at 1 per 2 hour period. Don't think the owners would part with the beast (that ole lawyer liability) If you're starting from scratch, I'd do like Bubba suggested and hit HPD up for a power-valved beast....installed in one of their 250r chassis'.
