Why are the stats metric? SAE would be better. No idea what 170km per hr is. Nor do I want to do the math.

This guy his motto : The definition of can't doesn't exist . i knew about this bike earlier, i was looking for a vw lupo 3l, its a reliable engine which has a lot of torque, ended up finding out about a 3l motorcycle,the lupo 3l itsself had a terrible gearbox, so this will be the best gearbox the engine ever had, good job kees!

I have a 1969 Honda CB450 (exactly like the one at 5:51). At the time it must have felt lightyears ahead of the Triumph Bonnevilles. My one is a Californian import and is a restoration project.

Its just too expensive to run a diesel now days, I have to pay about $90 on just 1000 kilometers for road user charges, which for my Toyota regius van it is equivalent to paying over $3 a liter for the fuel...

torque doesnt matter. only horsepower. common reverse double misconception

Suzuki have made dohc, dry sump all in a daily rider 2006 to today they still make the M109R. 160 nm 😉😉😉

Your Buell nice try Harley Davidson water cooled two stroke two cylinder less five grand new cubic inch your Buell are cc duu don't race your own motorcycle with new motorcycle owner .mine was pretty fast .but put lit into desighn reason motor crank area dident leek no oil in crank areas notice principles of two stroke firing cyclic kinda miss mine but enjoyed my rz ,350 much better was every day ride maintenance free special tools to change oil the fuel gauge would been nice on Harley Davidson Cafe racer by way bought from catalog delivered to door in large box no assembly tools with lots of assembly needed am guessing reading writing comes in handy duu

Wish they made a trike

If it was shaft driven I would have one

The CB450 was not Honda's first DOHC engine the CR72,CR77 and CR93 were all DOHC and pre date the Black Bomber by a couple of years these were over the counter racers and legal for the road but still volume production. Honda was no stranger to DOHC as all their racing machines were DOHC up until their withdrawal from GP racing in 1967 the difference in design with the CB450 was using torsion bar valve springs.

In 1965, this bike had near modern performance and drum brakes front and rear. 🤦🏼‍♂️

In the early 1970's I had a couple of trail bikes, then realized I was a road rider. I saw a 1971 used CB 450 for sale. gold with a black tank stripe, a mini 750. 1971 was when both the 450 and 750 came to full classic style and mechanical development. Later, I had a Triumph Daytona and could see the best of 500cc British and Japanese side by side. The Daytona was fun, light, good sounding and handling but if I was doing a long ride, I took the Honda. A friend had a Bonneville, perfect for backroad fun, maybe the best balanced, sexy, responsive bike, but Lucas electrics, Amal carbs and a tendency to shed parts. I rode the 450 for a couple to years and sold it for more than I paid. If I still had it, I see I could sell it for a couple of thousand more than I paid, a great bike and good investment.

dammm! For sure i would buy one! Love diesel whereever!

1969…bin ich mit einer CB 450 zur Isle of man gefahren. Auf dem Mountain Course habe ich ca.10 Runden zurückgelegt. Das Fahrwerk und die Bremsen waren sehr abenteuerlich.Ich habe es überlebt.

I had the pleasure of owning a 73 & 74 CB 450. I loved riding those bikes, but they required a lot of maintenance and there was a problem with the valve adjustment after 20,000 miles.

That 2-cylinder motor looks huge from the side, when compared to the 70s Kawasaki 900 4 banger.

The first dohc that i remember was a yamaha 500 twin. On the streets at least

The engine was a technical marvel, but it was a slug on acceleration, and the CB450 could not stay close to my Suzuki X6 Hustler in 1/8 mile dragstrips. The 250cc X6 was quick in it's day.

Looking back, it is unfortunate that Honda took their time getting the OHC timing chain, guides, and adjuster up to the quality of the rest of the engine. Because that is what happened to each and every one of them, anytime after 40,000 miles was attained, the whole thing blew to pieces.

I had that same colour CB500T 30 years ago, great bike, never let me down, just had to keep a check on the long camchain and torsion bar valve spring clearance of 1 thou/inch, not an easy adjustment but otherwise bullet proof.

"Wa sec co" - Did you mean Wiseco pistons? I bailed out on this video at 6:05 due to that.

DOUBLE OVERHEAD CAMSHAFT...Not every Viewer would know what the DOHC Abbreviation meant. nearly good.

King of the baggers are just a few seconds behind super bikes

I want one!

AI videos suck !!

That torque is crazy mate not even hyperbike has that torque,everyone thinks the hp or kw is the shit but i bet this thing will smoke a lot of modern bikes.

I remember their advent well. Lovely engine, and those single torsion bar valve springs were really 'different'. Pity the frame wasn't a bit better.

The brakes were terrible, better never have an accident with these old bikes. Great looks, great sound, but unsafe by today standards. I had a CB360, at least it had a front disk brake.

Was riding a Bonnie for street at the time and a Bultaco in the desert . 2 friends came by the house ,one on a 305 one on a new Black Bomber. . Southern Cal before idiots were elected. They talked me into riding the 450. After a few miles around Chatsworth Lake Reservoir I wanted one. I almost feel this thing would pull my 650 Triumph. Smooth as glass and shifting like a dream. Brakes (drums) actually worked. Nice ,still remember it. Out of reach today ,I got old.

I am sorry you have got that wrong the 165 and the 305 where the bikes that shook British bikes

I have a '72 CB450 K5 with about 2K on it and love it. Runs great and is a blast to ride.

Remember when Mr Daytona rode that turd into the hot-pit and before the chain-drive wallet crew could climb over pit wall he just unceremoniously dropped the POS on the ground and left 🤣

I had a CD200 Benly. Great little bike!

Very odd bike. Far too heavy, with leaf valve springs. Not much more power than a CB350 but more torque. It was a stop gap for the CB750 which killed off everything - smaller bikes included. I don't see what the ecitement for the rather boring CB450 was all about.

Hardly a new idea . A guy has built one using the vw 1.9pd diesel . 180 hp but in a low rider form .

It is not remembered as one of the most influential motorcycles in history.

This Savage was known as the 'Cabbage' in the UK. Treated with scorn and ridicule it sold in very low numbers. These posts are the first time I've ever heard anything positive about it! I love a good thumper but this isn't one of them. Sorry.

Got 3 xs1100 - great bikes

This engine had a really mean sound to it especially at high revs. I think most problems people had with this bike were due to bad maintenance like not using proper oil or not changing it often enough. It was as fast as most British 650s of the time. Of course most 400cc motorcycles today are 'starter' bikes!

A friend of mine had one. After a lot of miles, the cam drive sprocket at the centre of the crank wore out. For a while, he did a full engine strip every 1000 miles to replace the cam chain. Finally it got too much and he scrapped the bike.

The CB450 was really a good bike. I wish I had one today! QA friend of mine tried everything he could to "destroy" that engine, but it never failed!

You would think that a manufacturer that made its living designing and manufacturing large capacity V-twin motors could at least come up with a competitive bike,much like Ducati,or Honda,whose first attempt at a V- twin racer aced it against Ducati.Harley Davidson had the template already with "Lucifer's hammer",they should have gone from strength to strength,but I imagine that they didn't commit the level of resources necessary to maintain and develop a factory race division.

The CB450 had a wierd engine, valves closed by torsion springs not coil springs. This is totally against where Sochiro Honda came from as he spent years refining coil springs to work at high rpm.

What a load of bull-hit ! I knew two brother who bought CB450s new , with very mixed experiences . One was quite quick and reliable ( after he put decent tyres and rear shocks on it ) although the ground clearance was always a factor . The other brother had nothing but trouble and was happy to get rid of his .

New version of this bike would be great

This video is completely misinformed . The CB 450 was not , in any way Honda's first DOHC motorcycle . Honda were making DOHC engines as early as the late 1950s . Admittedly , they were racing engines . Honda first entered The Isle of Man TT races in 1959 with a team of six 125 DOHC twins . I think at least five of them finished the race and they won the team prize . All of Honda's 1960s race bikes were DOHC . In the early 1960's Honda produced a 125 race bike that was for sale to Honda dealers . It was called the CR93 . It was very successful . In order for it to be eligible for racing in America , they made 200 street models with the same engines . A very pretty little bike . The guys that make these videos should do a lot more research before putting them out there . READ SOME BOOKS .LOOK AT THE PRETTY PICTURES . 🤓

I have 2, a road K1, and a race 450/500cc. The engine vibrates a bit, but so does all the other twins of the era. Well developed race engines can produce 70+HP, and beat 600, and 750 twins. The torsion bar valve "springs" are only OK on a road bike.

Nothing to say other than, PERFECTION!

If my memory serves me correctly I was at the Pomona Superbike race where Chris Carr put the VR on the pole. Unfortunately he DNF'd in the race.

Funny you never mentioned the “technological advanced” desmodic valve adjustment “feature”. Honda NEVER used it again. A friend of mine sold his old CB450 that had been sitting in his garage for decades to some engineering students for a class project. $50.00. I passed because of the “desmotic”valve adjustment. Could have been why the other commenter’s bike blew at 7000 miles. I prefer low rpm torquey engines rather than buzz-bombs, like my 01 W-650. The “W” stands for WONDERFUL !!!
