Last friday on my way home on the DR along a very wet and busy (10mph) M4 around Newport, I was trickling between cars behind a 1100GS every so often I could hear a deep grumbling behind me, looking in the mirror I could see a headlight, after a while it was clear he was in more of a hurry then me, so I pulled over. As I did so a P reg (1976?) CG125 roared past (open exhaust). Rider looked relaxed and confident, good to see and older bike still going strong and used regularly.
