74 250MC frame pics needed

[Rosco400]

Has anyone got a 74 frame stripped they could shoot me a couple of pictures, was there much difference between the 72 and 74 frames, shock mounts in particular

I hope that the image came through ok as it is my first attempt at downloading photos using the villagephotos site ( thanks for the tips from Brad 090). I have not been able to make images small enough before.
As far as I am aware , on the '73 frame, the frame tube that runs from behind the footpeg up to the top shock mount is straight . I also think that the shock mount on the swingarm might be further forward on the '74. I have some more pictures if you want them.

looks to be a late 74.5 GP frame-move up frame and shock mounts, also note three holes in bracket by upper shock mount.

Are these frames growing in gardens in Oz? Here in US they are few and at least $600 US ? I see a few pics of them posted here, just wondering.

Thanks for the picture husky, same frame but the gussets have been cut off and need to make some new ones, i assume then that all 74 had the three holes. This was the bike that was previously listed by other forum member as full resto so just wanted to make sure it is done correct

 I have tried taking a cutting & planting it in the garden , but it doesn't seem to want to grow like Brad 090's A5 Kawasaki . This model Maico doesn't seem to be that common in OZ from what I have seen ,but they don't attract the same sort of money that they sell for on US ebay . Maybe it is because pre '75 class racing is not as popular in Australia as it is in the States . '81 490's are a different story though, fetching good prices here. I don't really understand the hype with the '74.5 GP Maicos , as I think that '73 model is just as competitive ( maybe more so ) with the way the rules are for this class . Because the '74.5 Maicos came out standard with about 6 inches rear wheel travel , you have to hobble them by putting spacers under the bump stop rubbers on the shocks to limit the travel back to 4 inches to satisfy the rulebook . Maybe I am just a rebel , but trying to change history to create a level playing field doesn't cut it with me . It should be either a pre '75 class or be called a 7 & 4 inch class . The poor old '74 Maico 250 only has a 4 speed gearbox , which puts it at a big disadvantage (once the extra rear wheel travel is negated )to just about everything else in the class that has at least a five speed . They didn't put a rule in place to say that all machines in this class are only allowed to use 4 gears to make it fairer on the Maico.

It should be either a pre '75 class or be called a 7 & 4 inch class .

This begs the age old question ( again ) do we pay homage to the era or a particular year?
Pre 75 is a nice catchy name, but it's more of a guideline than any hard & fast rule.

From the GMC spy files...
I have seen a few Maico frames & this one was one of the few which I considered genuine. I haven't seen the model with the holes before but am now led to believe they built a few different types of shock mounts.
Many have what look like home made mounts, just bits of flat bar etc. & the other give away is the way the tube is bent. When heated & bent on the frame the bend tends to squash flat a bit, Maico would have bent these tubes in proper formers before assembly as they did with the rest of the frame.
I have done repair work on a few frames that guys have said they bought because they were genuine 74.5 frames but they looked suss to me.




You will see more of them over here James because many people convert them, I believe the US has a different class for them so it's no advantage to convert them.

And if you want to fix or convert one I have these available in 4130 Cro-Mo,

Geoff, I saw that kit on you catalogue listing-wondered exactly what it was-now I know. Looks tempting as many frames from narrow 71 through std 74 are available here from time to time.
There are likely still more actual GP and converted frames here in US, but they seem to be the holy grail or something. The GP and conversions still run Sportsman in AHRMA( which is like pre-75), but must be limited to 4" or wheel travel here as well.
  As far as that rule, it has been here forever. I see where you can be at a disadvantage on a 73-74 250 Maico being a 4spd and all. That said, the 250 Maicos-until the 81s were not the rocketships of the 250 class anyway.
Still, the only other era bikes which come close in handling are the Monty VR,Ossa Phantom, Bultaco, and KTM-though the KTM is very heavy-a GP Maico still outhandles them IMO. Well, the KTM actually handles as well with laydown shocks (agian limited to 4"), and has great power, but the shifing is notchy, and you feel the weight. Again just my take on it.

In my time I've seen two, possibly three '74 Maico frame designs. Ulrich, my German correspondent worked for the factory and tells me that when the factory decided to go with the LTR  rear suspension in late '73 they had a stockpile of old frames that would have immediately become obsolete. They decided to modify all of the existing stockpile to the new design. The existing stock of airboxes were also cut down.
Many of the conversions are a little rougher than others, depending on the Maico worker who did it, causing many a dispute today as to whether a particular frame is legit or not. Sometimes you can't tell a factory modified frame from one done by the owner. The frame Husky Evo posted above is the first of the purpose built LTRs that came out in mid 74 along with a different, purpose built airbox and other changes. This is what the Americans christened the '74 1/2 model and we called the Update model.

This is a picture of my 400. The frame number starts with 393 , which going by the various  Maico I.D number guides makes it a '73 model . However, it looks like a '74 frame to me & if it is a converted '73 frame then it is the best job that I have ever seen. The shock mounts, bends in the frame tubes & welding look factory . What Firko has written above , maybe gives an explanation that it was a leftover '73 frame converted at the Maico factory.

Nice Maico HuskyEvo but what's that Mikuni thingy doing on there? Don't you know that Bing is King as far as Maicos are concerned ?

[Husky500evo]

I am a fan of Bings on Maicos ( even though they can be a bit messy when you prime them for starting ), & they apparently make more power than with the Mikuni .  I bought this bike as a basket case with no carby & it was just easier to buy a new Mikuni .

[Husky500evo]

This bike is fitted with a G.M.C pipe ,which I consider to be a work of art. The pipe performs & sounds as good as it looks.
