It's a Kramer frame, basically same as a yamaha monoshock but twin shocks

I remember Jack Pengelly was racing a Maico 400 in probably 1977 with a similar rear suspension set up.

Here is a link to the history of them, if you open it in google chrome it will translate the article

If it's a genuine Kramer it's the bargain of the month. If it's a home made copy as Jack Pengilly's was it's an interesting piece of period history that's illegal for our rules if you take the wording of the rule book as gospel. Cool thing.

[MauriceR]

I think you will find it is a copy as the original upper shock mounts are still showing

the jack penngally 1974 frame is still stored away.would it qualify for pre 75
it was avail back in the day?

[albrid-3]

it would not be eligible for pre 70,  you would have to proved its eligibility for pre 75.

It is a tricky one as to whether or not Jack Pengelly's frame would be considered legal or not. As it was used in 1974 it probably should be, but it would have to be restricted to 4 inches of travel.  Send an email to the MA Classic MX Commission through MA and ask the question.  If you can get photos and statements from people who know it existed in 1974 it wouldn't hurt.  The only problem is that it would appear to be a modified standard frame and the GCRs say 18.5.4.2. "Rear shocks absorbers will be in the original position using the original mounting points".  If the frame is a genuine Kramer frame it may be different.

Note the different angles of the shock absorbers between the genuine Kramer and the Craiglist bike. To me it's seem that the geometry of the Craiglist bike would tend to bend the shocks on the swingarms up movement. The real Kramer cantilever shock mount is higher and would push the shock instead of "bending" it.

Firko has heaps more knowledge than me but wasn't the really early Kramer Maicos offered as a kit form type modification. Read an early article of a US serviceman based in Germany bringing home a kit to the US and having it installed on his Maico. Loved the later version with the high pipe that came down in roughly a 45 degree angle from the rear of the tank towards the rear axle.

Fat chance getting MA to approve a bike like that for pre 75, they cant get their head around the fact that alloy swing arms were available from suzuki in 77..

I know what you mean John but if the bike was a genuine Kramer it'd shit into pre 75 as long as the 4" rule was observed.....and then what would be the point? The 74 Maico was the best handling pre 75 bike by a mile so why bugger around with it. Kramer's were cool but they weren't any improvement over the stock LTR.

I think that's the actual bike you mention with the fella in the Hellbent jersey Ross.

[JohnnyO]

I don't think it's a genuine Kramer Firko the swing arm shape and the angle looks wrong..

Which one John? Here's some genuine Kramers.....
