[chefod]

I'm looking for a suicide switch for my GS500F and have come to a conclusion that there is only two sizes of handlebars 7/8ths or 1 inch, so if anyone knows, please post a reply, oh and by the way i mean a cruise control also known as suicide switch

7/8 inch.  Harleys have 1 inch bars.

Tha Japanese use metric sizes when designing bikes and manufacturing component parts, your bars will be 22, 24 or 25 mm diameter. They are the prefered sizes closest to 7/8" and 1"
