A50 /A65 Swing arms

[Mike Farmer]

 

Yes I think we have  reached the right conclusion on this. I always run with 4.00 x 18. Approx 26" total diameter  The peripherr difference between that and (I think) 350 x 19 approx 26" diameter both properly inflated is less than half inch. That of course depends on the tyre tread form. Piddling amount. But I considr the 400 x 18 gives a better ride. However as You guys are now aware I can no longer ride so its purely accademic ----that posh for dont matta  much.

Take care and enjoy.

I have just been out to the garage and measured the swinging arm on my 1962 A65 from the centre of the bush to the centre of the suspension is 14" the width where the spindle goes through is difficult to get exact with the wheel fitted but I make approx 73/4" certainly not 81/4"

Thanks again gents. That really tends to confirm my thoughts of an altered SA. Certainly no other reasonable explanation. I am awaiting another which I hope is going to be the 14.125" and 7.75" in the jaws.

The positive aspect is that I know the one I have aint right. I have another in place at the moment but it belongs to another (eventual) bike.

I hope my other one arrives tomo then maybe I can put this one to sleep.

Thanks all for your interest and input.

Mike
