IMHO, I reckon,, 1971 round case X5 MC250

71 engine because the X5 250 went on to receive sandcast outer cases for 1972
That style of 250cylinder head didn't appear till the 1971 X5

The swing arm has a narrow space between the pivot tube and brace tube = converted Square/barrel arm.
Frame has narrow seat subframe = first appearance X5,
Round clutch cover needs "through frame" outer cable anchor underneath in frame cradle = still a squarie frame=X5
That is one hell of a rough LTR conversion = X5 frame converted.

So a rough LTR conversion to a 1971 X5 close ratio MC250 with a sprinkling of some
rarer 125 goodies ;D ;D ;D
As for as fiberglass tanks go,,it has a desirable smaller 125 tank
it also has small diameter symmetrical 125 front hub, but it is the wide one which does not crack like the narrow one does= desirable,,,,,

I would say it is a 1972 modified standard narrow frame....I would also bet if you pulled the head and checked the cylinder it is stamped with a 72 date. DG

Maybe the new owner will be a OZVMX forum member and share,

Much for muchness ;D ;D ;D
In my experiences with the round die cast engine cases,,,,
I reckon he will see the top of the cylinder stamped in the earlier half of 1971
or possibly even a late 1970 stamping
Anyhow thats the horse my money is on
 ;D ;D ;D ;D

You could of had a sandcast or round cover 71-72 I think it was more luck of the draw on what cover you got. If you was lucky you would get the round small cover. The tank is just a small maico tank that could of come on any  maico not just a 125. The front hub is correct also.....this is just a plan old 72 SB 250 maico with the shocks moved up. DG

Me neither, I have a smile as big as a slit in a water melon ATM ;D

Maico, known for altering supply and so did some of their dealers.
And more to the point lingering unsold stock
Horses are funny things too,,
My punt is the new owner will see /71

And we agree on one thing, its a coverted X5 narrow frame, identical to 71 72 except for number prefix progression
  Happy Fathers day Doug and all,,enjoy ;) :)
I am out of here, signing off, Mick :)

Ithe original colour of the Tank under the orange looks to be blue, I would say its a 69 model, I do know Keith stackers original 360 is blue tanker.

I haven't ran the motor numbers to see what year it was made.....I guess what I was trying to say is you could have had this maico in 1972. I will use three maico SB 250 as a reference that I was the 2nd owner of and all three came from the same dealer 70 miles from me. One was a 71 wide frame and the other two where 72 narrow frames. All three had the same small full hub. The 71 had sand cast clutch and ignition covers, one 72 had the same sand cast covers as the 71 and the other 72 had the round covers on the clutch and ignition. All three was T transmissions. The 71 had the small tank and the 72's had the bigger tank. I don't know why maico put what part on a bike when they where building them....did they run out of parts and used what was handy? So yes this motor could be a 69 it doesn't matter.....you could have purchased a bike that looked like this bike and then made the frame mod. Thanks DG

About the sand cast clutch cover. I think it was made for the big clutch that they was starting to put in the late 1970 or early 1971 400 SB....it was 25mm wider to fit the big clutch. So to use it on the 250 they made a clutch push pin that was about 50mm long and about 13 thick. This was not the best setup! the smooth small cover was a lot better. You can make a better clutch setup with the small cover and a bit newer clutch basket that had the oil holes in the back of it....now I'm just rambling....I will shut up now. Thanks DG
