Good luck with your search Mr Wasp, if you do get lucky and end up needing some parts I ended up with some NOS and repo stuff that I didn't really need that may come in handy for a resto.
OMG,NOS,OEM,RMT,CDI,NLA,WTF!

Perhaps alter your title mate?

MX360B would be a 1974 twin shock bike.
If you love it, lube it.

I had an MX250B.  It was the first model cantilever and it was '75 (on sale late '74). And it was an MX B.  Alloy white tank with red sides and vertical black stripe. The 360's I think had yellow instead of red.  Got it registered so i could get my "L"s!!! Universal rear tyre really hooked up on the bitumen, mono's out of every corner!! Unreal fun, cant have been too many cops around Geelong back in the day, never got picked up. Ha ha.

This is interesting as maybe the first year model cantilevers were MXB and then Yamaha designated them YZ after that? It's odd as i think the first YZ was a C model in '76?

The MX400B was the big brother to the cantilever 250. It had yellow styling  accents.
The YZ360 is a completely different and much rarer and more valuable animal.

Oh yes in '75 it was the 400 not 360.  So Wasp must be after the first YZ monoshock, not the first ever monoshock?

Now I am confused .  :o  . I always thought the YZ B where the first mono shock model.

Yes i think they were as well. 1974 YZ80/125/250/360 A models were all twin shocks

Would that mean 360 and 400 ran parallel in 75 or consecutive ?

I'm pretty sure all those models were MX not YZ.

I'm very sure the first ever mono-shocks were the 1975 MX 250/400B.  Yamaha ran a prototype works cantilever in late '73 and developed it through '74 before the production MX B cantilevers hit the market in '75. (works bikes were called YZ before the factory bikes went to OW in 76?)

I reckon the first mono-shock "YZ" was in '76 - which were the YZ C's - unless someone can disprove any of that?

Yamaha models got a bit confusing in the 70's as they produced the MX & YZ series side by side and their model designation letter was all over the shop as well.
Not to mention year models that were available in Aust were different to the US

To the best of my knowledge;

1974
MX 125 A - twinshocks, yellow
MX 250 A - twinshocks, yellow
MX 360 A - twinshocks, yellow

YZ 125 A - twinshocks, grey
YZ 250 A - twinshocks, grey
YZ 360 A - twinshocks, grey

YZ 250 B - monoshock, white, possibly the first monoshock, a 74 model in Aust but a 75 model in the USA
YZ 360 B - monoshock, white, possibly the first monoshock, a 74 model in Aust but a 75 model in the USA


1975
MX 125 B - twinshocks
MX 250 B - monoshock
MX 400 B - monoshock

YZ 125 C - monoshock, white


1976
MX 125 C - rare to find

YZ 125 X - yellow - airforks
YZ 250 C - yellow - airforks
YZ 400 C - yellow - airforks


1977
Designation letter now in sync
YZ 125 D - white, first plastic tank, steel swingarm
YZ 250 D - white, first plastic tank, steel swingarm
YZ 400 D - white, first plastic tank, steel swingarm

Now updated
Now updated yet again!
