This is the bike that started my motorcycle obsession, in the summer of 69 I was 10 years old and my big brothers friend would come ripping up the road on one of these bikes, I could hear home coming from a long ways off and I would stop playing with my hot wheels to check out that bike and start driving my parents crazy for a mini bike which I got a year later, a c70 which I’ve still got, since then I’ve owned over 50+ bikes but never a 68 cb450 until now, this one came up on Craigslist for a reasonable price so I quickly sold a couple of bikes and went and bought this for half his asking price, with all my bikes that I plan on keeping for a long time I’m taking it down to a bare frame to find out it’s needs and work my way back to getting it on the street....

Nice find. A 450k1 is on my list of bikes I want to own one day. I have a k0 already. Its looks like youve got a solid starting point. I can't wait to see how this turns out

Sweet - a black K1 is a handsome bike indeed.....

Several years ago I picked up a late 68 European model with the five speed. Its now a basket case in need of a rebuild. Vin information is in German. I don't have the beautiful original chrome tank like yours I wish I did. Beautiful bike congratulations!

Merely asked a question, thought there might have been something wrong. Larry

Looks good and nice and original in the first pic.

Moto nut · « **Reply #11 on:** February 20, 2018, 11:16:32 AM »

It’s going back to as original as I can make it with a few improvements.....

Moto nut · « **Reply #12 on:** February 27, 2018, 05:57:35 PM »

Well I got my painted engine back into the painted frame, next is steering tapered roller bearings, and bronze swingarm bushings......

DurangoCB · « **Reply #13 on:** February 27, 2018, 06:03:32 PM »

Really digging it, D. I'm so stoked you got that bike.

Tell me about the paint- did you have someone do it or DIY? If DIY, what type and color and what sort of prep?

Call me if you'd rather not type it all out.

Super sweet! My first moto experience was watching my dad figure out his 1974 CB450. My first hands on experience and my first bike was a 1973 CB450. Went thru the whole process of rebuilding the piece of history. Building our bikes together is something I’ll always enjoy remembering. I’ll be watching the progression of this bike for sure!

jas67 · « **Reply #16 on:** March 10, 2018, 04:06:41 AM »

Congrats! The K1 CB450 is one of my favorites. I'd love to have one some day.

Moto nut · « **Reply #18 on:** March 19, 2018, 07:29:00 AM »

Well this project is moving along, with valves adjusted, new bronze swingarm bushing, roller bearings, fork seals, and a hondaman ignition, next is new wheel bearings....

Nice!!!!!! Always been a fan of the 450. I'll be trying to keep up with this build, myself. I have a couple of 450 "Projects myself. Bought them several years ago, to build 1 out of the 2. Just seemed like every time I turned around,
something would happen, to distract me. but now, I believe I am about to where I can actually do it. Can't wait to see your come together. Gotta appreciate your approach on this, taking it all down and going completely through it. Shouldn't be any surprises, for sure.

Great job so far. I love it

Nice thorough work, buddy. She sure is a looker.

Moto nut · « **Reply #22 on:** April 09, 2018, 08:21:48 AM »

Well I’ve got the new wheel bearing installed and the front wheel is on for the last time, still waiting for new rear sprocket, I had to rebuild the tach and handlebar controls and still waiting for the original seat from upholstery shop but the one in photo looks pretty good.....

rocket johnny · « **Reply #23 on:** April 09, 2018, 08:36:52 AM »

nice bike and a good score ! years ago i had a 71 cb 450 , never should have sold it .

DurangoCB · « **Reply #24 on:** April 09, 2018, 09:22:13 AM »

Looking good!

I'd be tempted to keep that seat- looks pretty killer. She's almost together and you still have 2 months to spare. Can't wait to hear that bike in Palisade.

Moto nut · « **Reply #25 on:** April 09, 2018, 09:53:53 AM »

Actually that seat is the one I bought for your CX.....

DurangoCB · « **Reply #26 on:** April 09, 2018, 10:14:23 AM »

I should finish up this CB500 by June/July and start on the CX toward the end of summer. Maybe I'll try to talk you out of that seat eventually!

jas67 · « **Reply #27 on:** April 09, 2018, 11:43:13 AM »

Wow, looks great! You work fast (or at least have more time to work on your bikes than I do).

Moto nut · « **Reply #28 on:** April 15, 2018, 05:57:58 PM »

It was a good weekend, got the new rear sprocket so I was able to install rear tire, chain,and assorted parts, got the exhaust on, finished some bugs in the starter wiring, kick stand installed, hand controls mounted, headlight installed, and set the points, still waiting for the original seat.....

DurangoCB · « **Reply #29 on:** April 15, 2018, 06:05:52 PM »

So sexy!

Fantastic! Did you do start up yet?

RJ CB450 · « **Reply #32 on:** April 16, 2018, 09:27:58 AM »

Not sure your overall levels with the 450 DOHC engine, saw you had the covers off to do valve adjust. Anyways, really have to watch with rocker arms. They are extremely wear sensitive.

The three killers of the 450.

1. Not keeping the valve adjust perfect.
2. Even slightly low oil.
3. Letting it idle on the side stand.

1 is fairly obvious, 2 and 3 are related. Simply put, you have a tall and big head with a small oil piston oil pump. So just sitting, it cannot feed enough oil to the whole cam. So if you start, you run. If not are revs and upright, you are wearing the engine hard. Such an amazing engine, just that the engineers neglected the oiling unfortunately.

Moto nut · « **Reply #33 on:** April 16, 2018, 10:35:16 AM »

Thanks for the info, and no I haven’t started it since the clean up, I want to go over the valves, points, and cam chain adjustment again just to be sure, I’ll go with the points on the first few start ups then transfer to hondamans ignition later......

Very nice looking bike. I took my first road trip on a blue 1968 CB 450. Road from Lawrence, Ks to Colorado, in 1974. It ran good, and was running great when I sold it 10K later. Wish I still had it.

Well I’ve got the original seat back on and have been working out some small bugs, but all in all this bike is turning out pretty good, have tried to post photos with no luck, something about file size being too big, same camera and photos as before....
