1" Narrow Mini Apes Handlebars  

Our 8" Rise Narrow Mini Ape Handlebars are made from 1 inch OD x 0.109" wall premium 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 8" of rise and sufficient pullback, these bars are very comfortable and fit stock 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.

Available in two configurations: "Smooth" for custom applications or pre-1982 controls, or "Dimple" for 1982-newer Harley controls. Dimpled bars are drilled for internal wiring. 

Available in two finishes:  Triple chrome plated, or durable satin black powder coat.   

Note: please see photos for dimensions and specifications to confirm fitment of your motorcycle.

Does not fit throttle by wire models.

Smooth configuration bars may also be used on many Triumph models or Metric Cruisers with 1" diameter stock handlebars.

This is the most versatile option, working well with virtually any custom build style from choppers to bobbers to cafe racers.

Ribbed: The ribbed design adds structural reinforcement through integrated ribs, providing maximum strength for heavy-duty applications.

Installation Notes:

These fender mounts are designed to be welded onto your motorcycle frame at the desired mounting location. Proper positioning and alignment are critical for correct fender fitment and appearance. We recommend:

• Test-fit your fender and mounts before welding
• Ensure proper clearance for tire, suspension travel, and chain/belt
• Use appropriate welding techniques for your frame material
• Clean and prep mounting area before welding
• Paint or powder coat after installation to prevent rust

Professional installation is recommended if you're not experienced with welding and frame fabrication. Each TC Bros fender mount is manufactured to exacting standards for reliable performance on your custom motorcycle build.
