I have lost track of how many cb750's I have owned. Every year and model except for K0. They all got their plus's and minus's. Just like all bikes...to be perfectly honest? The only bike I ever owned that I just couldn't stand for was a Yamaha XS750...what a terrible piece of garbage. All the 750F's are under-rated. F0 and F1 are way ahead of the curve. And my F3 would spank a K1 and my money is pn the F3 would beat a K0 too...until the valve train wears out lol. So many other great bikes...CB/CL twins, CB550's? XS650's, Kawi fours, KZ650's are seriously under rated too! Suzuki's? love an X6 hustler what a sound! Recently even fell in love with a 67 Suzuki 50cc 2 stroke...so smooth. I will just stop now.
