Gen 1's are faster than Gen 2's. Gen 2's weight more and have taller gearing. Yamaha went for more touring less sport on the Gen 2's. I rode a Gen 2 liked it!. I like my 05 more. Try wheeleeeing a Gen 2 then Wheeleee a Gen 1,much easier!. Gen 1's corner sharper, shorter swing arm. On the highway...
