Title: 1973 Honda cb450
Post by Gus on 12/07/15 at 11:17:09

I had the  honda and the Yamaha 750 for sale on Craigslist all last week. There was a little interest but never moved anything. Yesterday I pulled out the Honda, filed the points, pulled the plugs and cleaned them. Ended up with spark @ the plugs so I squirted a little gas in each cyl. And cranked her over. She popped but never started.
I didn't work on it more than an hour or so. I don't. Have a compression tester but the cylinder will blow your thumb off the hole. I will admit the spark wasn't the greatest. It just didn't have that nice blue color. So I suppose if I'm gonna go any further new plugs and points will be in order. It was interesting to find out it, at least, wants to rumble.

If you were closer I would be interested myself.  My first bike was a '69 CB 450, and if I found one for the right price.......  :)   (Of course I might be sleeping on the sofa and condemned to eating my own cooking....)

What I found interesting about his bike is the over all design. Very well thought out and solid. Everything seems accessed easily. Plugs and points are easy to get at; etc. I was just @ the farm store and ngk plugs for it are 6 George's. That's doable as long as points aren't much more. I hate to spend to much on it but I it runs I may go all the way and take Daves advice and get a new title from what ever state that is.

Any small engine shop should have the points. Standard issue Briggs or Kohler item.

Resurrect it, bondo up the rough edges of the frame , spiffy the dude up, maybe? Dang shame it's not a 750.

From 1965 until 1969....the CB450 was the biggest, baddest motorcycle that Honda made (then came the CB750).

I can remember going to the local County Fair when I was in junior high and seeing the Honda motorcycle display....and being amazed by the CB450 on display.  At that time I had been riding my dad's Yamaha 125 twin (YAS1C) off road......and the CB 450 was a bike I could only dream of owning someday.

Maybe I'm  a simplton; two carbs is my limit. I've have my share of 4 cyl. motorcycles. But that's just me.

Title: Re: 1973 Honda cb450
Post by justin_o_guy2 on 12/08/15 at 07:15:46

Actually,I agree with the carb counting. Just a 750 will sell.

Post by Gus on 12/08/15 at 07:55:12

Justin, you really think so? I been looking at bikes for a long time. In this neck of the woods, it seems, there are a lot of 3 & 4 cyl. bikes to choose from with very few big singles & twins being offered. At least road ready ones.
I think there is an exceptionally strong market for big singles and twins; here anyway.

Title: Re: 1973 Honda cb450
Post by Serowbot on 12/08/15 at 08:01:41

A lot of people buy multi-carb/cyl bikes and ride them 'till they see the maintenance bills...
That's when you see them show up on Craig's... :-?...

My buddy (Ham Lee, nice Irish kid and former R.T. man in my platoon) who taught me how to ride, had a BSA 650.  He rode my 450 and pronounced it the better bike.  Comparatively maintenance free and ELECTRIC START !!!!!

Go look, that's an early year, done right, drool time.
I know a guy in Odessa who had a 450 , showroom floor till today ,I suspect. Dual leading shoe, I think. You might have a better bike than you know. Look it up, in good shape.

Justin, on that site, there were only 2 CB 450's. Both are at least 10 years newer than this one I found on a scrap pile.

I SEARCHED the 750.
Then I searched the 450.  I didn't post that link, because there are several.  Do. a search of your model,CCs,

the CB 450 is a pretty good bike, I with Honda still made the 450 Nighthawk, I'd really like one of those

I like the 450 Rebel/Night Hawk motor too.   8-)

Probably has power like a Savage . but as a twin  :).

Be nice to have a new one that might last as long as a Savage .

I will never be a good typist  ::)
The Nighthawk actually made 45 HP, 15 over the savage, and had a 6 speed gearbox *drool*

Title: Re: 1973 Honda cb450
Post by Rodger on 01/18/16 at 06:57:23

Yep, had one of those 6 speed, 3-valves-per-cyl 450 twins. The 6th gear was an overdrive, worked well for cruising on the flat or mild hills.

A friend got a new late '60s CB450 back in the day. It was a beautiful bike, aimed at unseating the British twins, which it surpassed engineering-wise. But it was heavy.

The other guys in school had Honda 65's and 50's and one guy had a Suzuki 120 single. The 450 reduced everybody else to no-class status. I got to ride it around the neighborhood one time, scared the bejeezus out of me. It felt like straddling a steam locomotive. How times have changed...

Art : Here one is :  Thing is : this and the S-40 would serve the same purpose .     Of course 45 Hp. and 6 speeds and twin cylinder smoothness  :-? :-? :-? .
If the Honda had a single carb , I believe I would do it !  :)

I had a Honda CD 175 with a single Carb and it worked good (for a 175).

Is it me or does it look like the forks are bent?
Either way 1000 bux for a 1982 motorcycle is sorta steep, let alone 2500, unless it is SOOPER PERFECT, which you don't know untill you look at it in person

still too much for a 34 year old Nighthawk, unless it was gold plated

Savage, curb weight 381
Honda 450, dry, 392

Id sure like to ride one and see how it goes, off the line and around the corner.

Title: Re: 1973 Honda cb450
Post by Sonny on 01/21/16 at 21:47:04

The linked review of the CB450 gives a wet weight of 430lb. The weight was carried higher than on a Savage.

It felt heavy as a bank safe to me at age 16 or 17, but all I knew were some friends' Honda 50's, 65s, a Suzuki 120. Those things felt like bicycles.

This is a pretty good article, with a bunch of MC history in it.

Post by Rodger on 01/22/16 at 05:32:59

Like the Model T....available in any color as long as it was black....

Ahhhh, memories....my very first bike was a '65 CB160...2 cylinders, 2 carbs, 1 set of points, black "toaster tank," no turnsignals, & a seat that felt like a vinyl-covered 2x6...and I LOVED it...lol. The battery would only click the starter solenoid, so it was kickstart only, & (until I did a ring&valve job) smoked like a 2-stroke scooter.

Hey, other "old guys" like me, remember when a 450-500cc was a Big Bike? I lusted after several bikes way back then: the CB450, the CB350Four, the Triumph Bonneville 650. My first long trip was on a CB350K4.


Title: Re: 1973 Honda cb450
Post by Dave on 01/22/16 at 05:44:26

Yep....I am that old.

I started riding my dad's Yamaha YAS1C....125cc two stroke twin around the farm, and then a bit later he got a ratty Honda 305 Scrambler.  As a 100 pound kid that 305 sure was a handful when I tipped over.  I can remember seeing the first CB450 Honda at a dealer display at the County Fair.....and it looked incredibly powerful to me.


Title: Re: 1973 Honda cb450
Post by Art Webb on 01/22/16 at 07:28:15

The 68 black bomber isn't really the same as the 80's Nighthawk, we're talking 20 years separation here, and Japanese companies didn' move as slowly as american companies back then
The Nighthawk line was a light weight bike that carried it's weight well enough that the MSF used them, in 250 sioze,  alongside the Rebel for their basic Ridercourse for decades, and a few of them are still soldiering along in that capacity
even a 750 NH was a light (for a 750) easy to handle MC that was nimble and quick
http://www.motorcyclespecs.co.za/model/Honda/honda_cb450sc_82.htm
https://en.wikipedia.org/wiki/Honda_CB450SC
although I might have found them heavy, and even top heavy, compared to a 50, they compare very favorably to the S40 and will walk it in a straight line, around a curve, or on the freeway
(the S40 will get the jump off the line, but the NH will show it it's tailight by the top of 2nd gear)

Title: Re: 1973 Honda cb450
Post by Rodger on 01/22/16 at 10:21:10

Very true, Art. All that the NH & CB450 had in common were 2 cylinders, CV carbs, & chain drive.

The 450 Nighthawk can be traced to the 400 Hawk (starting in '78, I believe), using the 2-intake/1-exhaust valve per cylinder configuration. Had most of the advantages of DOHC/4 valves per cylinder, but only one cam, so simpler and less expensive to manufacture. Also, was fitted with a vibration counterbalancer.

I had an '82 CM450...very similar to the NH, but kinda-sorta cruiser styled, similar to what Yamaha did with their 400 & 650 twins. Nice mid sized bike, but not as classic as the CB450's were, IMHO.

Title: Re: 1973 Honda cb450
Post by Art Webb on 01/22/16 at 10:26:51

what can I say, I like the NH better  ;D

Post by justin_o_guy2 on 01/22/16 at 12:46:59

Yeah Rodger. The guy down the road had a 750 when I was 14 or 15. All of us boys on the block stopped whatever we were doing and watched when he rode by.
God, how did he EVER get his parents to go along with That???

Sonny, good article.

Why is Twin Cam better when one can run 4 valves?
