Yeah, looks like they put the front wheel/forks on round the wrong way...

Yep, front wheel mounted to wrong way facing forks..should be leading axle, not following axle...

Are you serious, Paul?
I remember reading that they a heap of crap but surely they didn't really have a trailing axle???

The tyre would also hit on the rear of the front fender, could be interesting...
I wonder if the piston is facing to right way.

oldyzman prettywell covered my first thoughts--as in wouldn't like to be first to land it hard off a jump. Was a YZ80k on trade me [for ever] don't think it sold but [the old story] fully rebuilt, no cost spared etc--& forks in back to front. Worried me so much [new buyer gets injured] that i had to point it out diplomatically but never got a reply & pic never changed--give up.

You think I'd make that up? They surely did make a trailing axle :-[

xz400/550 was a pain in the arse, carbs were twin downdraft with accelerator pumps & hoses going everywhere. Were carb mods & airbox p**s flap updates early on. Flap was controlled by a vacuum diaphragm thingy that controlled the air at the airbox entry by memory. Reminds me--had one at work that someone had put sealer stuff in the tank & fueled it up too early no doubt, then this bloody cat piss smelling glue went through pretty much everywhere it could get in the carbs. The 550 was raced in the 6 hour over here [nz] but remember constant fiddling during the practice days before then think big ends the night before--not sure if it saw the 6th hour in the end. Steered weird too but probably 'mind over matter' because they look 'wrong'. Had a lot of offset [step forward] on the yokes so everything theoretically worked out with sliders reversed but i could never see the point in it apart from a gimmick [yamaha trickery]. Sorry getting off subject--what was it again!!].

Sold a pair off XZ550 wacko forks a an XZ enthusiast couple years back. He almost had a heart attack with excitement when I said is $20 to much??? Weird!!!
I still have the engine somewhere it is running a 45mm side-draft Weber carby.  Another one day project I will not get too...
In the parts that came with the wreck are the heaters that used to be in the leg fairings, they ran off the liquid cooling system like a car.

Tim, Tim, Tim, Maaate, you could turned them around and swapped them left to right and listed them as workx forks!! You could have sold the for for a $quillion mate ::)

Well bugger me!  :D

I remember seeing that model, but never noticed the weird forks.
Sounds like they were a complete dogs breakfast, just the sort of thing I'd like.  ::)

Yep Tony the Yamaha research and design crew had been smoking the saki and poisonous fish guts through a water pipe that day...

Then again I was and maybe still will re-engineer a small Sprintex blower on to the little V-twin.... it's the Weber makes easier to construct the manifolds    shame about the shaft drive...

we seem to have got another countries orders of XZ400 versions  cheap ( probably did not want a slug version of a lemon in their market repeated !

after about 2 years these things all started  developing STARTING problems ..... so head gasket x 2( were about the prime ministers salary ), and a valve job later , job later you had a bill for what you paid for the bike, and it was still a boat anchor.
don't think anyone collecting these....oh and one person in nz tried to race a 550 , on alcohol I think.. a slug on speed....

Him or the bike??   ;D ;D ;D

hope it was him, cause if he was serious , the bill for therapy would dwarf the valve job.....

Well There ya go, I had one of these engines for a while. I found it left in a property I purchased many eons ago.
It was in pieces. The bores looked as though it had done bugger all. Eventually, I gave it to Dyno. Still to this day I have wondered why anyone would have pulled it apart, with such low K's. Now I finally know why, thanks.
