Was the VN700/750 engine really designed for a NINJA?

Hello...I read somewhere....possibly somewhere on here that our engine was originally designed for a ninja. Is this really true? I mean with specs like 10.3 to 1 compression ratio, DOHC, 8 Valves, 4 spark plugs, ignition control box, Water cooling, balance shaft,......this all sounds like way too many awesome features for a cruiser V-TWIN! I guess maybe KAW was doing this to have a technilogical lead over the other V-twins of the day????? If anyone has info about this subject I would like to hear about it. Thanks!

I have read this statement here myself several times too, so I have accepet it as true.
I am not familiar with Ninjas though, so I can`t really confirm it as a fact.
After googling ninja 750 and looking a a few links and pictures, I am still not sure.

I know from the Kawasaki site that the VN500 engine is the same as a Ninja engine with a few changes but back in the day there was talk about trying to make a V-Twin sportbike/Ninja. I don't believe it ever went anywhere after that.

LTD 454 engine is a copy of the Ninja 900 engine but with only 2 cylinders, which is why it's half the displacement (908cc for the Ninja 900) and the EN500 is the same concept... when they discontinued the Ninja 900 and the Ninja came with a 1000cc engine, they did the same thing as before and took out 2 cylinders and got a 500cc engine.

No idea what the deal is with the VN750 though, aside from what I've read here as well.

I can see it being in their plans,Yamaha had the Virago v-twin cruiser and while the Eliminator was a cruiser ,I think they wanted a V twin type cruiser to eat into the Sportster Class of mdweight V-twin cruiser market.

But the technology they had in the VN7xx engines were pretty much cutting edge for a v-twin when they were introduced.This leads me to believe they possibly were developing an engine for a sport bike.

Can you imagine what the Ninja 650r with a fuel injected version of the VN750 would be like,especially with a chain drive with a little different gearing than than the Vulcan would run like with DOHC and 8500 redline and that elusive 6th we all look for with the torque of the Vtwin.

I'd buy that in a minute,it would be one bad little ride that was easy for a beginner and able to thrill the more experienced riders as well.

I think there are many clues that point toward this engine,being designed for more sporty purposes,the shifter shaft location ,the bevel gear housing that looks like it was an after thought.The oddball air intake.and the air adjustable
shocks that also have dampening adjustment.

I have no evidence but it looks like it could have been so! JM2C

Ninja? No. The Vulcan 500 (opposed twin) is simular to one of the Ninja models and has interchangeable parts with it.

From what I heard the motor was at some stage originally designed to be used in one of Kawasakis watercrafts. Not sure if they used a V twin for that application but that's what I heard. The Vulcan 700 motor was the first V Twin Kaw built.
The 750 motor was not used in any other motorcycle and shares no engine parts with any other motor that I know of.

You got that right, I read it and it was so old I didn't even remember commenting on it.

The question that begs to be asked is, how can thread that old be on topic and one a day old has completely derailed ?

Such BS it aint funny........

Apologies Herr Knifemacher....but yer WAY wrong....the 700 engine, which is the same 750 sleaved, was used on quads and watercraft as well....

I seen a trike....which was made from a snowmobile engine, reverse trike....made from the same V twin we have.....was rough and gnarly too....but ran like a banshee....

Research....aummmmmm....research.....aummmmmm

This beastie is fairly new to me (3 yrs)....but I did a sheitload of diggin......and findin out......

...besides was no such thing as a "Ninja" in 1984.....
