Back in the day when Lancashire working men Don WHillans and Joe Brown, were powering up new climbing routes over North Wales, the Lake District and the Alps, Triumph brought out their sporty model: the Tiger. Appropirate advertising.
Here's Don himself heading off to Grindenwald and an attempt on the North Face of the Eiger; Chris Bonington is pillion. Climbing helmet as a lid, mountaineering mitts for gloves; look at that hemp rope! The bike is most likely a Triumph Tiger.
