1982 prototype shown

Postby Lorcan » Wed Jan 14, 2015 1:34 pm

The 750 turbo (ZX750E1) was released as a 1984 model at the end of 1983, alongside the all-new GPz900R. Although carrying GPz badges on the engine covers, it was only referred to by Kawasaki as the "750 turbo" - the GPz tag wasn't mentioned. Development started in January 1981 as a turbocharged 650, then as a 750 from November 1981.When finally released, the stock bike made a claimed 112 hp, had sports bike handling (for the day) and looked good - especially next to the other factory turbos which were already on the market - the Suzuki XN85, H*nda CX500 and 650 turbos, and the Yamaha XJ650 turbo. Performance was on a par with the GPz1100, at around 11.2 secs at 125mph for the quarter mile and 148mph flat out. One magazine even branded it the fastest bike they had ever tested, and Kawasaki ran some ads claiming it to be "The Fastest Production Motorcycle in the World". Jay "PeeWee" Gleason also famously recorded a 10.71 quarter for Kawasaki to show that the turbo had genuine performance and was ahead of the other factory turbos. Around 5500 E1 units were made, and approx 2500 1985 E2 models, which were identical except for twin throttle cables, and minor changes like brake caliper decals.

This 1982 pre-production prototype was exhibited at the Tokyo Show, alongside the XN85 Suzuki turbo. The fairing was formed from sheet aluminium. Note the wing on the upper fairing, the absence of a lower fairing, the fashionable leading-axle forks and the Dymag H-spoke style wheels.

The cradle around the turbo dosnt look like it would protect much. I think the extra 12 months of development before release was a big improvement on looks alone.

Agreed, although I prefer the single pipe with "turbo" on the silencer to the heavy twin silencer production setup.

I can't see any reason other than aesthetic vogue of the day for twin pipes in the final design.

Wonky beginnings! Interesting to see more detailed viewpoints. Definitely many R & D alterations.
'Orrible leading axle design with anti-dive units tucked forward of, and drawing fluid from the calipers. /^X
The proto-turbo appears smaller/different plus intake changed. 650-esque side view. Aviation queues with riveted alloy fairing!

That is one ugly fairing. Looks as though it fell off a H*nda!

Think fugly Japanese aeronautics. The aesthetics department still managed to retain the faux-rivets on side-panel upper edges.
Rumors: Big K scrapped fighter plane queues due to governing bodies & insurance companies rumbling as to inferences "It's designed to fly".
They did add that supersonic alloy brace for good measure, ultimately turning out one of the most beautiful two-wheelers of all time!
