Many! In addition to all those already mentioned, Chater Lea made a neat face cam 250. And yes, the same Raliegh made motorcycles, with Sturmey Archer engines and gearboxes. Also, I believe the first motorcycles by what would become Indian were made for pacing of track bicycles; this had been done with tandems or triples, I think, before the motor age.
