I see that there were several different handlebars available in the same year for the different models. Were the Euro spec bars mounted to bikes to be sold in the U.K., and the "western" bars for bikes destined for the U.S. market? Was it just a matter of general prefernce that the UK riders preferred the somewhat flatter and narrower bars? Any other real reason for the difference? I do realize the apehangers, like mine (ughh) and the interpol bars were also mounted on some bikes.
