1974 Honda CB750 from United States of America - Comments

Check out http://100megsfree4.com/honda/h0700/four.htm for speedometer specs. The only Honda's that could register speeds that high was the 1979 dohc bikes. The speedometer read up to 150mph. After that the speedometers only went up to 85mph. My personal experience with my stock 1979 k2; after 120mph it handles like a tank made of Jell-O.

I bought a brand new 74 Honda 750, and went from Miami to Middletown NY. Awesome touring bike, but the claims here of speeds up to 138MPH is highly exaggerated. 110 is more reasonable. And it was very cold blooded. If you wanted speed, a Kawasaki 750 or 900 was the bike to own.

My 78 CB750 F2 has a speedo that reads 150, not that I've ever seen it. And my speedo is off but in the other direction, when I am doing 40 on the speedo it is really 50mph. To the mate that has only seen 85 at top end, you're not the only one. I suspect it is either ignition problems or compression. I have 2 cylinders that ran kinda cold, but now I am leaking a bit of oil from the head. So it needs a top end redo, with new rings. I'm thinking of getting it bored to 836cc.
