Same front end 51 M21 - 53 A10

Does any on know if the the yokes forks etc for a 51 M21 and a 53 A10 are the same - interchangeable?

Thanks

Some parts would be the same and some different.

The top yoke of the M21 would have the bolt holes to hold the speedo bracket whereas the A10 would not due to having a cowl, that wouldnt really matter though.

The right fork slider would be different as the M21 has the 7" brake and the A10 the 8". The fork slider for the 8" is just a plain slider but the one from the M21 which has the 7" would have a cast lug which locates the brake plate as well as hold the cable adjuster.

Hello Brian, Thanks for the reply. The A10 has no cowl, looks the same as the M21. The M21 also has the 8" inch brake fitted. The only external difference I can see is that the M21 head lamp has the under slung side/park light, the rest seems the same?

PS 51 A10 and 53 M21 - oops

If they both have 8" front brakes then everything should be interchangeable.

Here's a pic of my 53' M21, totally original. Everytime I get to the point of starting on it something else comes along and it gets put back in the corner. Oneday I will get to it.

Thats exactly what I had in mind for this one RR, it runs and can be ridden as it is but I will go through it mechanically and rewire it etc before I do any serious miles on it.
