Might as well start a new thread here. I've got dibs on an 82 (?) Yamaha XS400 SECA with 73 supposedly original miles. I trust the guy selling it and it appears to be in wonderful shape. How's the power on these? I wasn't worried about the 650 having enough balls to get me around and I assume the 400 will fill the bill too? Mostly around town but possible short freeway jaunts. The bike feels pretty light to me but I'm a good 250lbs plus whatever gear I'm luggin. Anyone ride one/know specs and what not?
