In the 1960's, A British cruiser type motorcycle (BSA, Triumph, Norton, Etc.) that has been modified for speed and maneuverability on city streets by lowering the frame, souping up the engine, adding a small fairing or small windscreen, Etc. These bikes were street-raced from one cafe to another, and from various cafes (Particularly the ACE Cafe) to London Bridge and back.

This is a complementary term that is still used today to denote any cruiser style motorcycle (But NOT a crotch-rocket street bike!) with the same characteristics.

Predominately using the beatiful wideline frames of Nortons (the worlds greatest roadholder) mainly Triumph engines and some BSA. Large aluminum petroltanks (Manx-type), cuts, clip-on handlebars, fott-rests moved back and short racing seats.
