Ramsgate electrician Harry Laslett invented the motorcycle twist grip and received a U.S. Patent for his design in 1925. Harry had his electrical shop at 39 Queen Street, and lived at Queensgate Road. Members of the Laslett family still live in Ramsgate.

Glenn Curtiss, unlikely to have been aware of the prior uses of the twist grip, used it in his 1904 motorcycle land-speed record machine, and is sometimes credited as the inventor of the device.[1][4] Indian claimed in their advertisements, also for their 1904 models, to have invented the twist grip.[4] Whether Curtiss, Gottlieb Daimler, or Roper, were the true inventors, the 1904 Indian would be the earliest use of the device on a production motorcycle

I've had quite a bit of correspondence regarding this article, but the Patent is there in the name of Harry Laslett. There were several variations based on the same concept and I have to say that I've not seen the Harry Laslett design on any of my motorcycles.

Harry Laslett lived at 33 Park Road, Ramsgate and my father inherited all his tools when he died (~1980), infact I've got a few too.
