Biltwell 1-1/8" Tracker High O/S Motorcycle Handlebars

Oversized and tapered dirt-bike style handlebars are all the rage on high-performance Harleys, but construction shortcomings limit their function and appeal. Our Tracker OS bars pair well with our Murdock OS 1-1/8" risers. Our OS bars taper to 1" at the ends unlike a dirt bike bar which requires shims. All are available slotted to accept stock H-D cable-operated throttle and hand controls or notched for more modern TBW (Throttle-by-wire) technology. No compromises. No problems.

Technical Details

• Tubing tapers down to 1-inch O.D. on grip ends to accept stock and aftermarket H-D hand controls
• TBW option has a 1in O.D. on grip ends with a 20.9mm I.D.
• Slotted option has a 1in O.D. on grip ends with a 19.4mm I.D.
• CNC mandrel-bent radiuses for laser-straight ergonomics and all-day riding comfort
• CNC-machined slots for H-D hand controls and bottom of clamping area for internal wire routing
• Black electroplate and mirror chrome-plated finishes available
• Right-side bar end notched to accept internal H-D TBW module on throttle-by-wire version
• Technischer Überwachungsverein (Technical Inspection Association, or TüV) in Germany is an independent laboratory that tests the fatigue strength, manufacturing quality, and fitment for a wide range of consumer products, with special emphasis on automotive and motorcycle components and accessories. Biltwell handlebars and risers that have received TüV verification are among the strongest and most thoroughly well-tested motorcycle parts in the world.

Form and Function

Oversized and tapered 1-1/8-inch handlebars are common on lightweight dirt bikes and many European and Japanese sport machines. Thanks to some progressive thinking by modern big-twin customizers, this technology has migrated to high-performance Dynas. Unfortunately, the aluminum material used to make tapered bars is not ideal for big-twin bar construction. Unlike steel which bends or cracks before breaking, aluminum can fail without warning, especially when subjected to the stress of controlling a 600-pound motorcycle. One great way to improve the strength of aluminum handlebars is to increase their wall thickness. Unfortunately, this isn't possible with modern Harleys because the resultant small inside diameter would make TBW module fitment impossible. Our tapered and butted 4130 chromoly solve all these problems. We employ advanced tube tapering and CNC bending technologies to ensure every Biltwell Tracker OS bar is stronger than stock and straight as an arrow. CNC slotting and notching lets you install stock H-D hand controls and throttle modules easily—no dangerous shims or drilling required.
