Both of these have popped up locally. The CB is $1200 and the Seca is $1700(both asking prices). Both are supposed to be in good order, seca looks better in pictures but who knows. I've read up on the CB's over the years and know a bit about them but the seca is a fairly big unknown for me. It's only a year older(83 vs 84). Both are supposed to run and ride properly. Will the Yamaha likely be as reliable, or should I go with the honda? Both seem to both fit the same niche, sporty old UJM's. Always had a thing for th cb700's but this seca is pulling on heart strings, admittedly it'd pull harder if the prices were the same.
