I saw the info posted on the TYM Website also, and I do believe that the only major difference between the 273 and 293 is the larger tire size. I took possession of my '09 - 273 in April and I'm totally satisified with it. However, I cannot see any HP difference. The 273 and 293 have the same motor - where is that extra power (2hp) supposed to come from? I certainly don't see it. They list the exact same motor spec's for each model. I agree with Bob, if I buy larger wheels/tires can I redesignate my machine as an 293? I don't think so, but it might be real nice to have the additional clearance/stance that those tires would give. I just don't see how TYM can list it as what it apparently is not -- a larger HP'd machine. Just my .02..... nevertheless...TYM, if you're monitoring this -- I do "truly" love my 273.
