🖼 image.jpg (photo damaged in backup)🖼 image.jpg (photo damaged in backup)Hi guys new to forum
Got a St 70
Says on log book 50 cc previously registered overseas
Trying to work out age. Frame number St 706315861
Also on frame where usually printed honda this is a badge!!!
Looking inside the frame its clipped in any idea how to remove this as would like to keep
Thanks for any help

Those frame badges are used on '69 bikes with low-type exhaust.
However, your frame number suggests it was built between 1979 and 1981...

Cheers mate thanks for your reply

Hi
If the badges are fitted correctly they can be prized off using a paint scrapper or something like that on mine the badges came out with the little clips, these can be obtained from David Silver and are used on loads of different models.
Also the pre 70's machines had a plastic fuel tank but this is not a accurate way of dating a bike.

Hi got the badges off they were stuck on as well
There is a plastic fuel tank
I was trying to work out age as I need steering bearings and there are no numbers on old ones
Thanks

Check the right side of the frame (under the foot pegs)
If there is a fixation point for the low exhaust, I guess it's a '69 frame with a 'new' frame badge.
Steering bearings should be the same for all pre- 80's versions.
