'79 CB750 limited edition?

100hp honda · Post by **100hp honda** » March 16th, 2008, 2:06 pm

does anybody know anything about this bike? '79 CB750 limited edition. the guy im staying with has one he will sell me, we havent worked out a price but im thinking $1000 or less. the guy is the original owner and bought it brandnew in '79, the bike is near perfect shape and was garaged its whole life, and has 6,400 original actual miles. the motor is 4-cylinder with dual over head cams. were these decent bikes/motors ?? would the motor work good in a hill climb chassis??? only thing i was dissappointed at, it only has a 10,000 RPM redline on the tachometer

heres the same bike

That bike rite there is the first ever 'superbike' they are an awsome motor. Not modern powerful but in '79 they ruled.

A buddy of mine had and still has one, I have personally been on the bitch seat with him dragging his knee around a blind bend on it.

It would be a shame IMO to pull it apart so you can put it in a dirtbike frame and polish it......

i really wasnt planing to pull it apart. i was just in the garage looking at it and its in pristine condition and the dude hasnt rode it for alot of years so he mentioned he will sell it. im not familiar with them old bikes and mainly wanted to know if those motors were good. but it sounds like they were decent running bikes. he said something about 85hp-90hp LOL, that aint very much by todays standards for a 750cc but thats fine

Heres something I found with a quick google search....

"I have a 1979 Honda CB750K that didn't run when I got it out of a guy's barn 3 years ago. After the brake caliper rebuild and full carb disassembly and cleaning, the bike would hit an indicated 135-mph. Stock!! Then I got the bug...it has MAC 4-1 exhaust, K&N filters, jet kit and lots of custom weight loss/body modifications. It weighs 450 lbs. with oil and gas and makes 95 rear wheel horsepower. I haven't had a chance to take it to a timed quarter mile yet, but it does rip. Only complaints are the flexing frame....I'm working on some aluminum braces for it and the crappy scary brakes. Compared to a modern bike, these brakes will give you a few good scares before you get used to them. The bike could use some more tire, but I have as wide of rubber as will fit on the factory wire wheels and I must say, it will wheelie and spin the rear on a hard launch. It is a bargain street racer and very very easy to sucker the frat boys into races. They often lose, thinking that the wire wheels and no fairing equal a slow old pig. Its the 2 wheeled equivalent of a 400 hp Nova in primer..the perfect sleeper. "

IIRC they are about 70hp.

Heres from wiki....

"Cycle Magazine called the CB750 "the most sophisticated production bike ever" upon its introduction[3]. Cycle World called the motorcycle a masterpiece, highlighting Honda's painstaking durability testing, the engine's 120mph top speed, the fade-free performance of the braking, the comfortable ride, and excellent instrumentation [4].

As the first modern four cylinder machine from a mainstream manufacturer [5], the term Superbike was coined to describe the CB750[6]. Importantly, the bike offered other important features, both great and small that added to its compelling value: electric starter, kill switch, dual mirrors, flashing turn signals, screw on oil filter, maintenance free valves and overall smoothness and freedom from vibration both underway and at a standstill. On the other hand, the bike was difficult to get on its centerstand and tended to throw chain oil on its muffler.

Unable to accurately gauge demand for the new bike, Honda limited its initial investment in the production dies for the CB750 by originally using a technique called permanent mold casting (often erroneously referred to as sandcasting) rather than diecasting for the engines[7] -- unsure of the bike's reception. The bike remained in the Honda lineup for ten years, sales totaling over 400,000 copies in its life span[8]

The CB750 is sometimes referred to as a Universal Japanese Motorcycle or UJM, although certainly the bike has earned notoriety of its own.

The Discovery Channel ranked the Honda CB750 among the top ten greatest motorbikes of all time, giving the CB750 third place[9]."

10 greatest bikes of all time?? that sounds good. im alittle dissappointed if it only has 70hp though

britincali · Post by **britincali** » March 16th, 2008, 2:41 pm

It was the first street bike I ever rode, and if it seems like I love 'em.............. I do

It made the top 10 list as it was the first ever crotch rocket, almost everyone was running either vertical or v twins and honda came out with a high revving DOHC 4 banger in a decent chassis that actually turned and stopped.

By todays standards they suck balls but like I said in the 70s-80s they ruled up until kawasaki got big into the Z1000

britincali · Post by **britincali** » March 16th, 2008, 2:47 pm

This one is identical to the one my buddy has...

I went on the back for a 4 mile ride and when we stopped at the gas station my legs gave out. It was the scariest ride Ive ever had on a bike, knee down at 90mph hitting the cats eyes in the center of the road with the frame flexing and tires squirming. I walked home......

100hp honda · Post by **100hp honda** » March 16th, 2008, 2:52 pm

i think ill buy this bike, if nothing more than i can ride it to work for $10 week gas. i would rather have a 1000cc but i can probly get a good deal on this machine as the dude hasnt rode it for years and probly will just let it collect dust

britincali · Post by **britincali** » March 16th, 2008, 2:56 pm

For a grand I would definatly buy it.

100hp honda · Post by **100hp honda** » March 16th, 2008, 3:01 pm

i havent discussed a price yet because i cant ride the bike for a couple more months. but im sure i can get it for less than a 1000$. probly $800-$900 if i flash cash in his face. he said he paid $3000 brandnew in '79

make a package deal with a saws-all and get it

My bro and our buddy nick built this machine, Nick had broke his leg last jan, so he kept the starter, alernator, and battery on it. You should see the look on guys faces when this thing lights up on its own in the staging box. This weekend he put suspension and brakes from a '98 cr500 on it, and plans to ride it out in the valley on the weekends.

Something like that is gonna be my next dune bike, very

a friend of mine in high school got a cb750 as his first bike, he let me ride it a couple times, it was a super smooth ride with no lack of power. I wasn't fighting to hang on like riding an R1, it was smooth and comfortable, and had plenty of pick-up for when some HD rider thinks his 100 year old technology is fast.
I was bummed when he sold it so someone other than me!

I say buy it, but don't molest it, keep it nice and original, that would make the perfect commuter.

nick rides it here to our shop, probably 4 miles from his house on saturdays, and out to the valley, probably 25 miles. he's got all the lights and stickers for dot, might put a plate on 'er this summer.

I'm pretty sure this piece is referencing the original SOHC model introduced in 1969. It was way ahead of everybody at the time.
Then came the Kawai Z1 in or around 1973, then the Suzi 750 and finally Yamaha.

Honda went to the DOHC sometime in the late 70's.
This 79 seems like a good purchase.

However it is the early 'Sandcast' SOHC that will and are becoming big with collectors.

anybody know what the limited edition consisted of in '79? the bike looks identical to the picture i posted on page 1. i was thinking fancier rims and different paint than the standard model was the limited edition but i really dont know

Mad Dog · Post by **Mad Dog** » March 20th, 2008, 7:35 am

I don't know for sure but I'll take stab.
Stepped seat with rear grab rail vs straight with grab strap, different bars with a little more pull back, 4 into 4 pipes vs. 4 into 2, paint and wheels.

Another possiblilty. Around this time Honda had a 2 stage, Hi / Lo transmision that gave 5 + 5 gears.
I don't know if this is the one but I believe it was activated by a lever on the left side by the side cover.

BUT I AM NO EXPERT!!!!!!!!!!
