Changing handlebars is one of the most common things done to customise a motorbike, and can dramatically impact the appearance, comfort and way you ride. For a chunky look, fit Fat 1.25 inch (32mm) handlebars. Most 1.25 inch bars are sleeved down to 1 inch at the grips and centre section, so you can keep your existing hand grips and risers even if you've got 1 inch handlebars fitted at the moment. If you want even fatter 1.5 inch handlebars like the ones by Tolemar you will need new 1.5 inch riser clamps, but these bars are sleeved down to 1 inch at the grips. If you ride a Harley, make sure you buy Fat handlebars designed for Harley-Davidsons with the smaller centre section or you will have a noticeable gap at your top clamp.
