Working on a friend’s cb450. Nice bike! She’s a small lady and just loves it!

Finished up the cb450 today. Took it for a short run. What a sweet ride with an amazing amount of torque and acceleration! In 1970, this was a “big” bike. My wife rode it up and down our road and called it”cute”.......

Were you able to identify any interchangeable parts that ended up going onto a cb750k0 in early production?  Caliper, ignition etc.

Front wheel, caliper, font fender ( single cut at the back) and caliper brackets all looked the same. Not much else...... delightful, smaller design. Really tightly packaged, but all extremely accessible. No vacuum ports for sync’ing the carbs, so I used my old “Unisyn”. It fouled the choke butterfly when open, but used a slice of old radiator hose to extend the carb throat. Sweet bike.

Yeah, it was hard to disregard that bike. I didn't: had a CL version first and a CB version later. Both were a joy to ride! At hiway speeds they could get a little tiresome, though, with the vibes in the handlebars. But I'm talking 8-hour days, here... ;)

I see her 450 and raise you mine!



Apparently, the Honda 450 was faster then the British 650's back in the day.

 Rear turn signals and mounts are the same also for anybody needing some for a K0 or K1 750. I like the blue color.

It was painted by a local body shop. Turned out well and it does look good.

Steve: Is yours the 4-speed? Those are really rare...
We used to call the early ones the "Bone Shaker Twin". They could cut a license plate in half in a single day's tour.

Hey Mark...yes, it's a '67 K0 w/4 speed.  Nearly all original, picked it up from a buddy that has a couple of them. Went for a ride earlier today, it is a "vibrater" but runs great!
Only original once, I wont be restoring it.
