Which bike?

Hmmmm..... Sounds like it has an interesting past?

the original owner is probably still looking for it....

Hey jimspac iam chasing a set of mag wheels and a new stereo possibly a big screen tv aswell.

Ha Ha Ha

The XP number from the factory was showing and that number checks out as 1986 XP. I have not been able to understand why the 1987 Prefix 842251951H was added. That prefix was only used on 1987 250 frames

Here 310 Huskyte a 1985 WR400 that needs a proper headlight and some stickers to make it real.
First year of the single shocks in Australia.
Was registered in Queensland and runs and stops well although it will need a rebore in the future.
Everything else has been replaced down to wheel bearings.
$3650 cash on pickup in Warwick Qld.
Don't really want to sell it so price fixed.

sweet bike, should be all over that like a well fed kid on a sweet cake in a paper cup

Has the wrong headlight and a later back guard but everything else is correct and it's cheeper than the one he was looking at.
A headlight/guard and a sticker kit and there you go.

that is a 1985 WRX 400 here in the states. 1985 WR 400 was a twin shocker. 1986 was first year single shock WR with front disc brake.

I had a 1985 250 version-as WRX said, mine was a WRX.
Blinkers and everything-nice!

My 86 400wrx had the round front headlite with the rectangle rear light. With single shock and front disc.

Genuine Australian 1985 WR400 with Australian compliance plate that says so.
When I bought it it came with the correct but badly weather beaten plastics.
Couldn't find a decent headlight at the time and liked the later back mudguards .
So seeing as how it was to be a personal rider that's how it ended up.

Cheers for that mate, I appreciate the offer. Your bike is safe! I have other things I have to pay for now.
Nice looking bike too!

like a garage ceiling ....?

if yr from NZ its a "grudge"

A few people both here and on Facebook have said that this bike is a WRX but if the engine number / frame number and compliance plate all say it's an 1985 WR400 then is it a 1985 WR400 ?

The combination of Drum on the front and mono on the back is unique to the 1985 WRX in the US models. I believe that European Huskies have the same 1985 mid-model-year variant by a similar name.

The '85 WR engine should swap into an '85 WRX or '86 WR frame as a straight swap, or at-least close to it. So, if you said you only checked the engine number, then it would be easy to say maybe someone had blended an 85 WR with an 85 WRX or 86 WR (the silencer looks more '86 than '85, at-least by US models). Frame and engine number matching 1985 WR with the pictures you posted doesn't make sense with what I know about mid-1980's Huskies. Then again, as a smaller-volume manufacturer, and us being in different markets, it's not 100% impossible that they released a few bikes late in the model year that didn't conform to the remainder of the model year (I would think they'd brand them differently i.e.WRX, though WRX and WR gearing differs).

Just to be clear. If it runs, rides, and you hold the paper that says it's yours (and the number stamped into the frame matches what's on paper), then I wouldn't worry much about what it's called.
Calling it a WRX versus a WR might be a big difference to the handful of people who know the difference between the two, but doesn't, to my understanding, do much to impact the value. And it doesn't do anything to impact the horsepower, ability to rip up grass, or piss off your neighbors!

my twin shock numbers come up as 85 as well...bit of a bitza year as they ran out the old twins boingers and bought in the new single pogo

Is it possible that the drum brake on the WRX is more powerful than the disc on the WR? Any factual tests out there?
