Boy racer

I heard a number of bikes pass the house - clearly old, British bikes from the lovely rumble. When I went through the village to get some shopping they were parked outside the pub so I stopped and grabbed some blip-fodder. I think this is a Norton Atlas but that's far from certain so if anyone recognises it please dive in. In the extras is a grey wagtail - I thought you might enjoy a bird as well as a bike.
