TC Bros. Narrow Apes Handlebars are made in the USA from 1 inch OD x 0.109" wall premium American steel tubing. They are CNC mandrel bent for ultra-smooth bends and flawless symmetry. Knurled riser clamp locations are 3.5" on centers to fit standard Harley spacing (not springer) and prevent bars from slipping once installed. With 16" of rise and sufficient pullback, these bars are tall enough to make a statement, while still being rideable. These bars generally require extended cables, brake lines, and wiring on most Harley models. They look great on any Harley, but especially good on Narrow glide front ends because, unlike most ape hangers on the market, the bottom of these bars are not wider than the trees. "Dimpled" for 1982-newer Harley controls. Dimpled bars are drilled for internal wiring. Durable satin black powdercoat finish. Note: please see photos for dimensions and specifications to confirm fitment of your motorcycle. Does not fit throttle by wire models.
