ok so i priced out a gixxer 750, and after being approved, i decided i just can't afford a new bike. So i am getting a gsx-r 750 still....except its 10 years old. Anyone familiar with the bike? i've ridden a few in the last couple days, they feel pretty nimble, nice power. one of them had the sprockets done and the thing was a wheelie machine. lots of power. any opinions? experiences on these bikes?
