Here’s a blast from the past, though I’m not sure how long ago this was done. Bob Horn sent in this link to a page from Kosman Specialties highlighting some fab work done to a Kawasaki ZX. The bike came their way with the Harley Davidson engine already mounted, after which they fabricated the Weber carb manifold, the rear frame loop plus a number of other necessary items.
I really like the idea of this kind of hybrid combination. Sure, some of you will ask why anyone would ever do a project like this but if you do, you miss the whole point. It’s neat. Maybe someone just wondered if he could or how it would work, sort of like the DesmoHarley engine project. Why? Because. No other reasons needed.

Is it me, or is that bike’s back wheel levitating a few inches off the pavement? That red thing on the right side must be the anti-grav device. Screw the Harley engine, I want the anti-grav device.
Bryce says
Looks like a Japanese Buell. Figures that Japan would already have anti-grav devices in motorcycle prototypes.
Duke says
…or Bob Horn has invented the invisible center stand. Is it really light too?
Mark L. says
I am actually familiar with this particular project bike. I talked with Sandy several years ago about this. It was a project for a customer that never got finished. It started life as a Kawasaki ZX7 chassis, and Kosman built the custom downdraft intake and a LOT of frame mods to put the Harley engine in the chassis. When we last discussed this in around 2002-2004, the customer never finished it, and as far as I know, just went to waste. Sandy does some outstanding chassis work for the drag bikes, and widens stock wheels as well.
Enjoy, Mark

Those unobtanium parts are really light, so light they float! I’m guessing a little Photoshop to remove a clutzy looking center stand of some sort.

The Witch’s Wizard of Oz bars must have scared the customer off. Put a basket on the front of that bike to compliment those bars. Oh no, flying monkeys! Run!
hopefully someone will finish this project with clip-ons. I like the bold & logical move of welding a bracket to the aluminum frame spars to tie in the lower engine mounts.
Ry says
I think if you put clip-ons on here you might get your face sucked into the throttle bodies. This anti gravity device must be what E.T. used.
I would love to build one of these it seems to me that the chopper is dead and motorcycles like this are going to become the next American customs.
Chris says
Yeah, that’s a crappy Photoshop job. Note the smudges on the driveway (which might otherwise be mistaken for oil spots) actually move with the bike in the two photos, and the driveway texture looks a little off directly under the bike.

There’s something missing, but I can’t think what…

The AntiGravity Mechanism would be great in terms of moving the bike around in the shop and parking in new and creative ways, but it seems to me that it would greatly decrease acceleration. (Is this bike designed to carry heavy side cases, perhaps?)
You’d need a curb or a speed bump if you wanted to do a smoky burnout, too, but if you could figure out a way to get it moving stoppies would be a breeze.
