T Bars on a Road Glide
Installing T bars on a Road Glide is one of the most popular, aggressive, and performance-oriented modifications across the modern Harley-Davidson touring motorcycle community. Originally inspired by West Coast club-style Dynas and FXRs, tall straight risers paired with flat motocross-style handlebars have migrated to the heavy-displacement Road Glide touring platform. Riders crave T-bars for their commanding upright ergonomics, razor-sharp front-end steering leverage, and performance aesthetic. However, converting the cockpit of a shark-nose Road Glide requires navigating fairing clearances, gauge cluster relocation, extended clutch and brake hydraulic lines, and throttle-by-wire wiring harnesses. In this comprehensive motorcycle technical guide, we evaluate riser heights, pullbacks, top tree adapter plates, instrument relocations, and installation best practices.
Performance Ergonomics, Steering Leverage, and Shark-Nose Fairing Dynamics
The primary mechanical benefit of installing T-bars or modular riser bars on a Harley-Davidson Road Glide is dramatic improvement in steering leverage and high-speed chassis control. Factory Road Glide handlebars feature a swept-back, relaxed buckhorn profile that places the rider wrists at an awkward downward angle, encouraging slouching on long rides. By bringing the handlebar grips up and forward over the fork stems, T-bars place the rider in an aggressive, upright attack posture, allowing you to push and pull through twisty mountain canyon corners with substantially less physical effort.
The defining architectural feature of the Road Glide is its frame-mounted shark-nose fairing. Because the massive fairing is anchored directly to the motorcycle frame rather than turning with the front forks (as on an Electra Glide or Street Glide), the handlebars pivot independently inside the fairing nacelle. Popular riser heights range from ten to fourteen inches. Pairing ten to twelve-inch risers with a one to two-inch pullback provides the ideal ergonomic balance, keeping your hands below heart level to avoid numbness while easily clearing the fairing inner speakers.
Review popular T-bar and riser configurations for Harley-Davidson Road Glides below:
| Riser / Bar Height | Pullback Profile | Hand Position Relative to Fairing | Wiring / Cable Extension Needs | Rider Profile |
|---|---|---|---|---|
| 10-Inch Modular Risers | Straight or 1.5" Pullback | In line with top of inner fairing | Can often use stock clutch & brake lines | Shorter riders (under 5'9") |
| 12-Inch Performance T-Bar | 2-Inch Kickback / Pullback | Grips rest 2-3 inches above fairing | Requires +2 to +4 inch line extensions | Most versatile; all-day touring |
| 14-Inch Aggressive Risers | 1-Inch Straight or Pullback | Fists level with rider shoulders | Mandatory extended hydraulic lines & wire | Tall riders (6'0"+) / Club style |
| Moto Bar on 8" Risers | Low-rise motocross bend | Aggressive low forward attack | Stock wiring fits; compact look | Canyon carving & performance bagger |
Modular risers (combining separate vertical risers with a clamping moto bar) have largely eclipsed welded one-piece T-bars because they allow riders to micro-adjust handlebar rotational pitch forward or backward to match personal arm reach.
Top Triple Tree Clamps, Gauge Cluster Relocation, and Wiring Harnesses
Installing T-bars on a modern Road Glide (2015 to present Rushmore and Milwaukee-Eight models) requires solving the gauge and ignition bezel challenge. Factory handlebars mount beneath a plastic plastic nacelle that houses the speedometer and tachometer gauges. To mount vertical risers, you must install an aftermarket billet aluminum top triple tree clamp or a dedicated riser adapter block that bolts over the stock tree. This setup requires relocating the factory dual gauge pod to the top of the risers facing the rider, or into a low-profile carbon-fiber fairing bezel.
Electrical wiring and hydraulic plumbing require meticulous planning. The fly-by-wire (TBW) electronic throttle twist grip sensor, left and right hand control switch wires, and heated grip circuits must be pulled internally through the riser tubes for a clean show-quality finish. When increasing height to twelve or fourteen inches, you must install extended stainless steel braided hydraulic lines for the front brake master cylinder and hydraulic clutch, and replace the factory soft rubber riser bushings with solid billet or stiff polyurethane bushings to eliminate handlebar flex.
Examine essential components required for a complete Road Glide T-bar conversion below:
| Component / Hardware | Material / Specification | Engineering Purpose | Critical Installation Rule |
|---|---|---|---|
| Billet Top Triple Tree | 6061-T6 Aircraft Aluminum | Provides rigid 3.5" riser mounting holes | Torque fork pinch bolts to 18 ft-lbs |
| Polyurethane / Solid Bushings | Heavy-duty urethane or aluminum | Eliminates tall bar flex and vibration | Never reuse soft factory rubber bushings |
| Gauge Relocation Pod | Billet aluminum or molded composite | Mounts gauges cleanly atop risers | Ensure wiring harness extension is sealed |
| Extended Hydraulic Lines | DOT-approved braided stainless | Compensates for extra riser elevation | Full bleed with fresh DOT 4 brake fluid |
| Wiring Harness Extensions | Color-coded CAN-bus extension kits | Extends electronic switch & TBW wires | Stagger solder joints to fit inside bars |
Upgrading to polyurethane or solid aluminum riser bushings is mandatory; using tall twelve-inch risers with soft factory rubber bushings creates sloppy handlebar deflection and alarming wobble at highway speeds.
How to Install T-Bars on a Road Glide in 4 Steps
Follow this step-by-step motorcycle customizer guide to disassemble, mount, wire, and align T-bars on a Harley Road Glide.
Disassemble the Outer Fairing and Stock Handlebars
Remove the shark-nose outer fairing, unbolt the stock handlebar clamp nacelle, unplug electronic switch harnesses, and remove factory handlebars.
Install Billet Top Triple Tree and Solid Bushings
Install a billet aluminum riser-compatible top triple tree clamp, replacing flexible factory rubber bushings with stiff polyurethane or solid aluminum riser bushings.
Internal Wire Hand Controls and Throttle Sensor
Pull the CAN-bus switch harnesses and Throttle-By-Wire (TBW) sensor wires internally through the risers and moto bars using guide wire and lubricant.
Mount Gauge Relocation Pod and Connect Hydraulics
Mount the digital gauges atop the risers, connect extended braided brake and clutch lines, bleed the hydraulic systems thoroughly, and torque all fasteners.
Frequently Asked Questions (8 Questions Answered)
Q1: What is the best riser height for a Road Glide?
A 10-inch to 12-inch riser height paired with a mid-bend moto bar is considered the sweet spot for most riders, offering aggressive control without blocking instrument sightlines.
Q2: Do you need extended cables for 12-inch T-bars on a Road Glide?
Yes. While stock wiring can sometimes be rerouted on 10-inch bars, 12-inch and 14-inch risers universally require extended hydraulic brake/clutch lines and CAN-bus wiring extensions.
Q3: Why do riders put T-bars on a Road Glide?
T-bars provide an upright attack posture that eliminates lower back slouching, dramatically improves front-end steering leverage through twisties, and delivers a sleek performance look.
Q4: What is gauge relocation on a Road Glide?
Factory Road Glide gauges sit inside a plastic console. Installing T-bars requires moving the dual gauges into an aftermarket billet pod mounted directly atop the risers.
Q5: Why are solid or polyurethane riser bushings required for T-bars?
Tall 12 to 14-inch risers act as long mechanical levers. Soft factory rubber bushings allow excessive flex and handlebar play, whereas polyurethane or solid bushings provide rigid steering.
Q6: Do T-bars hit the Road Glide fairing when turning?
Properly engineered Road Glide risers feature forward or pullback angles that keep bars and hand controls clear of the inner fairing speakers throughout the full steering lock.
Q7: Can you use heated grips with T-bars?
Yes, provided the handlebars are notched for Throttle-By-Wire and internal diameter allows routing the heated grip wiring harness through the bars and risers.
Q8: What is the difference between welded T-bars and modular risers?
Welded T-bars feature fixed crossbars welded to risers. Modular setups use separate vertical risers with a clamp that holds independent handlebars, allowing rotational adjustment.
