well the streetfighter style of motorcycle came from the brits
i remember MARTEK frames SPONDON HARRIS amonst others
also the hesketh was british and when malcom cox got his hands on one he customised it brilliantly
thats not counting the loads of cottage industry that make custom bikes
i know theres loads of others
the yanks like show
the brits like go
and even though my america has lots of chrome
