Anyone that doesn't recognize the CB750 as the first superbike is simply drinking Kawasaki flavored kool aid. The Z1 may have been better, but it was still released to the public after the Honda. Honda beat them to the punch, and Kawi was left to start over, peicing the Z1 together with Honda stylings.

The h1 was released the same year, why wouldnt that be considered the first superbike if we are going by release dates? It was a mean, green, deathmachine. It literally brought motorcycle performance standards to a whole new level. I am not a die hard kawasaki fan like many who r loyal to one brand even if it blows. But kawasaki DID have a huge edge from 69 through the 70's with the h1, h2, kz, z1. They continued to dominate til the early 80's with the gpz1100 and gpz750 turbo. but after that suzuki stole the thrown with its big 4 valve 1100/1150 motors that came in the gs and big kat. not real sure who was on top in the 90's, but suzuki definately made huge progress with the busa.

That's completely incorrect dude the Honda CB750 was the original superbike.... It was first built in 1969 and you can completely see where Kawi stole styling cues from Honda, so if you knew anything about bikes......

Completely incorrect?????? I think not. KAWASAKI (not honda) created the first idea/concept for an inline 4 cylinder 4 stroke, which they released at the international motor show. Kawasaki began designing the z1 as a 750cc 4 cylinder because there was a 750cc displacement limit in japan at that time. Honda beat kawasaki to the production line in 69 with the SOHC 750 4. Kawasaki then scrapped all previous plans, and knew that to build a TRUE superbike it couldnt just produce another 750cc bike to compete with honda, but that it needed to decimate all. The answer was a 903cc DOHC inline 4 that powered the Z1 in 1972 . (1973 is considered the first year for the z1, but few 72 z1's produced in 1971 were spread out all across the U.S. for test purposes to see if there was enough demand for such a bike) This motorcycle is the first true superbike in america. The honda may have been the first 4 cyl 4 stroke, but it still could not compete with the kawasaki h1 500 triple when it was also released in 69. Kawasaki continued to own the motorcycle world with its 500/750 triples, the z1 took over, eventually became the kz900 in 76. The kz900/1000 continued to decimate all for a few years. Suzuki later developed their 4v DOHC platform which was also very impressive. The z1 kz900 and 1000 , and also the 4valve suzuke gs1100/1150 still temain one of the most popular dragbike platforms to use. Air-cooled blocks are nice as they can be punched out to ridiculous sizes without worrying about hitting water jackets. So to wrap it up, the z1 is seen to be the first true superbike by most.

just hang on tight is about all you can do. Taking the bike to the strip this weekend, well see how well i can hang on.

i duno, just had the image of a short frame with a big ass back tire rightbehind the seat. That was the thought, the sawzall did the rest!

Clint Eastwood kicks ass

Excellent

that is the first thing most people think of, except the seating position is almost identical to how it was stock keeping it very rideable

That thing is totally bad fukn ass!!! Mad props to you. Wana sell it? LOL J/K.

hmmm, would think about it, got alot of other projects that need $$$$. Although i am very attached to it, and dont think i could let it go. AAaahhh i cant decide, DAMNIT!!!

yep, was planning on going chopper but ended up changing my mind.

This project began life as a 1978 kz650. A friend of mine bought it cheap from a guy who had it sitting in a barn. Some parts were used off of it, and then it was once againg placed in a barn to remain for the rest of its miserable life. I saw this and took action. I drew up an idea of what i wanted it to end up like and went from there.

Here is it in its original state. Mmmm aint it pretty

Here are some pics of the frame after what seemed like days of cutting and grinding.

dyna standalone ignition system. coils, electronic ignition, rev limiter/advance and retard curves, fully programmable.

how it sits today

This bike is very fast and alot of fun. With the work done it should make somewhere in the ballpark of 120hp. Never dynoed buy these are common mods for these bikes and others have had these results. It is a blast to ride and it is a good feeling to have something that is one of a kind that you built with your own hands. I thought about just buying a sportbike before the build, but decided against it because anyone can have a sportbike and i wanted something completely out of the ordinary. Its also a good feeling being able to keep up with the new stuff on a classic.

Oh ya, the goodies: 81 750 bottom end,810cc high comp. forged wiseco pistons, ported gpz head, gpz cams, head milled down to further bump compression, 34mm carbs with bigger jets. Rev limiter is set at 10,500rpm but she has a tad more life in her after that.

might be sold to a guy in fargo for $750. Sry, I might accept 500 if you were to meet me in aberdeen though.

I called the salvage yard today and tehy want 1300 for a good lq4 w/out wiring harness. Although there is a catch. They also include a 30,000 mile warranty. that would be a good deal for someone who plans on keeping the motor stock, but someone who plans on tearing it apart, but not so good for someone who plans on tearing it apart and voiding the warranty.

i dunno, i guess i couldnt stand to see it go for under 500. If i cant get that for it i guess i would rather part it out. ebay is always your friend

the motor has 80,000 miles. Was removed because of cracked flywheel. Engine was never reinstalled. It was from a service vehicle and the amount of money involved in labor was more than what a service truck is worth. Arent the heads alone worth more than the motor?

I dont know if this is the right place to post this, but i have been thinking about selling a motor of mine for some time now. Although, i have absolutely no idea what it is worh. This would be an easier decision if the motor was together, but the heads and intake are included but removed. THe motor is a lq4 6.oL removed from a hd gm pickup. It is nearly identical to the ls1, ls2, etc. except it has an iron block and a taller intake and a deeper oil pan. It is also lower compression, but basically the same. makes the same power and more torque. It has aluminum heads, all the accessories, and even all 8 coils. Does anyone have any thoughts or advice on what to ask for when i list it?

old bikes kick ass!!! what kind of bike do you ride? Check out my old kz. Pics of it are in the bike poll post if you didnt see it already.

CB750 < kz750, kz650, kz900, kz1000, etc.
