These stylish handlebars are designed to go with the 2014 to present OEM Bat Wing fairing as found on many Touring and Trike models. They have a 1" diameter lower section and then go up tapered to 1 1/4" for a beefy look. Can of course also be used on other models that have clamps for 1 inch handlebars. Bars are tapered to 1" for use with regular handlebar controls. They are slotted to ease internal wiring and are notched for use with Throttle-By-Wire.
