Hi All,
Great link thanks
Jeff Smith and Dave Bickers back in their youth doing what they did best!!
I can report that Jeff and Dave are both well and still riding BSA's

Jeff and his family rode a Gold Star combination, while Dave and his wife rode an RGS outfit (

)
on this years Irish National Assembly
The RGS is a USA import, and has an ARRT2 gearbox (low first gear)
Apparently some USA export models have this feature??
Regards
John O R
