Title: Early Motomag frames.
Post by: ghostriderx on January 09, 2007, 06:21 PM

can anyone tell me

which were the earliest Motomag frames, the one with a bracket welded near the rear dropout for the coaster arm to bolt to, or the one without the bracket and a clamp used instead ?

Cheers  :daumenhoch:

On my 1980 pics, BITD the coaster arm was clamped to the frame.  :daumenhoch:

It may have been earlier than 1980, Halfords had just started selling Team Murrays, BTW the memory fades at 36  :-[ :-[

Halfords had team murrays back in 81, motomags are much earlier 76 onwards I would have thought

thats my thinking too: very early ones no brake bridge at all but coaster tab
then both & think the coaster tab got dropped around 1980

Reilley might be able to help, he's a US member and has a huge (and highly desireable) collection of bikes that are pre 1980, if he doesn't know I am sure he knows someone that does  :daumenhoch:

so 75/6's had the seat/down tube gusset.
Then 76/7 had no brake bridge.
77 on till the 81 MK 2's was the goose we all know and love?

when did they stop doing the coaster bracket? anyone know?

Post by: motomagII on January 10, 2007, 08:25 AM

i had 78 one new and im  pretty sure no coaster tab on that

Title: Re: Early Motomag frames.
Post by: Coastvl on January 10, 2007, 08:29 AM

I have a 77 and a 79. The 77 has one and the 79 doesn't. That should narrow it down a little.

Think this picture answers my original question.nice one and thanks for all the info . It would be nice to know when they actually did drop the coaster tab or did they make both for a short while?  :daumenhoch:

my 79's and 80's don't have a coaster tab or gusset.

Title: Re: Early Motomag frames.
Post by: kdw712 on January 10, 2007, 11:51 AM

my 79 does have one
serial number is marked (from memory) CC9

so likely then mid / late 79 they dropped it

prob always find or two that will be the exception though i am sure
its mongoose after all  :D
