If you’ve ever thought about swapping out your Harley’s handlebars, you probably know it’s not as simple as picking a style you like and bolting it on. When I first looked into changing mine, I assumed I’d just grab a set of bars and be done. Turns out, it’s a whole process—measurements, cables, wiring, even legal limits. That’s why I wanted to put together this guide. It’s based on my experience and a lot of digging into what really goes into a Harley handlebar upgrade.
This isn’t a sales pitch. I’m not here to tell you to buy a particular brand. Instead, I want to give you the real-world information you need so you can make smart choices for your bike. Whether you’re going for ape hangers, T-bars, or just a subtle upgrade, knowing your handlebar dimensions—and what they mean—is critical.
Let’s break it down in simple terms.
Why Handlebar Size Matters More Than You Think
Handlebars aren’t just about looks. They change how your bike feels. The height, width, and pullback all affect your riding position, comfort, and control. Go too high or too wide, and you might end up with sore shoulders or numb hands. Go too narrow, and your bike can feel twitchy.
For me, the first time I rode with taller bars, I felt like I had better leverage in corners, but after an hour, my arms were burning. That’s when I realized how much these measurements matter—not just for style, but for long-term comfort.
If you’re just starting out, here are the key dimensions you’ll want to know:
- Diameter: Most Harleys use 1-inch bars, but some are 1.25 or even 1.5 inches. This has to match your risers and controls.
- Overall Width: The distance from one end to the other. Too wide, and you might hit your fairing. Too narrow, and it affects handling.
- Center Width: The flat part in the middle that sits in your risers. This is crucial for fairing clearance.
- Rise: How tall the bars are from the bottom to the highest point. This affects arm position and comfort.
- Pullback (or Sweep): How far the grips come back toward you. This changes your wrist angle and riding posture.
- Riser Spacing: The distance between your risers. Most Harleys use 3.5 inches, but Springer front ends are different.
These measurements form the foundation of your “Harley Davidson handlebar size chart.” Without knowing them, you’re basically guessing—and that can get expensive.
It’s Not Just the Bars: The Hidden Costs of a Swap
Here’s the part that surprised me most: changing handlebars is rarely just about the bars. Once you go beyond a certain size—usually around 12 inches in rise—you almost always need longer cables, brake lines, and wiring.
For example, on a 2020–2024 Low Rider S, if you jump to bars that bring your overall height to 12.5 inches, you’ll need:
- A 38-inch clutch cable (part 0652‑2475)
- A 26-inch brake line (part 1741‑6161) with an adapter (1742‑0658)
- 6-inch switch harness extensions (24020‑1106)
- 6-inch throttle‑by‑wire (TBW) extension (24025‑1606)
If you go up to 13.5 inches, those lengths increase again—to a 40-inch clutch cable and a 28-inch brake line, for example.
When I first priced this out, I was shocked. Between the bars, cables, wiring, and sometimes labor, the cost can double or triple what you expected. And if you’re going for internal wiring (which looks amazing but is way more complex), add in hours of extra work—or shop fees if you’re not doing it yourself.
That’s why I always tell people: budget for more than just the bars. Plan for cables, extensions, possibly new risers, and maybe even professional help if you’re not comfortable with internal wiring.

Throttle-By-Wire and Fairing Clearance: What You Need to Know
Modern Harley-Davidson motorcycles often use Throttle-By-Wire (TBW) systems instead of traditional cables. What does that mean for handlebars? Simply put, TBW systems need handlebars that can accommodate special sensors and internal wiring setups. Not every aftermarket bar fits these systems, so it’s crucial to look for bars explicitly marked as TBW compatible.
For example, some popular bars come with precise notches or internal slots designed to fit the TBW sensor and keep the wiring neat. If you ignore this, you might find yourself stuck with bars that physically fit but don’t work with your throttle system. I learned this the hard way after buying bars that looked perfect but needed extra wiring mods to function.
Fairing Clearance: Don’t Overlook This
If you ride a touring model with a big fairing—think Road Glide or Street Glide—handlebar width and pullback become even more important. Those large fairings aren’t very forgiving when it comes to space. If your bars are too wide or pull back too far, you risk rubbing against the fairing or even limiting your steering range.
Some aftermarket bars, like the Klock Werks KlipHangers made for Road Glides, are designed with narrower centers or unique bends specifically to fit inside the fairing clearance limits. But here’s a heads-up: Harley often updates their fairings. The newer 2024-2025 Street Glide models have “new style fairings” that can throw off compatibility—even for bars that fit perfectly on previous years.
So, always double-check if your handlebar choice matches your model year’s fairing design. Otherwise, you might end up needing costly adjustments or even switching bars again.
Riser Compatibility: The Fit That Holds Everything Together
Another key piece of the puzzle is the risers. Your handlebars need to match the riser’s clamp diameter exactly—common sizes are 1 inch, 1.25 inches, or 1.5 inches. If they don’t, you’ll either have a loose fit or require adapter bushings, which add complexity.
Also, pay attention to riser spacing—the distance between the centers of your riser clamps. For most Harleys, this is 3.5 inches, but if you’re running a Springer front end, you’ll likely need a wider spacing of 4.75 inches.
When I swapped bars on my bike, I measured the riser spacing first to avoid buying bars that just wouldn’t clamp securely. It saved me a lot of frustration and money.
Local Laws and Handlebar Height: Stay Legal
Before you get too excited about towering ape hangers or massive T-bars, a quick reminder—local laws on handlebar height vary widely. Some states and municipalities cap the maximum height from the ground or from the seat to the grips.
This might seem like a minor detail, but ignoring it can lead to tickets or even your bike failing inspections. It’s always a good idea to look up your local motorcycle regulations before committing to a handlebar size. Better to be safe than sorry.
How to Measure Your Harley Davidson Handlebars the Right Way
Getting your measurements right is the secret sauce for a smooth handlebar upgrade. I can’t stress enough how many times I’ve seen people guess or eyeball their bar sizes, only to end up with parts that don’t fit or feel awkward. Measuring carefully saves time, money, and a lot of headaches.
Tools You’ll Need
- Tape Measure or Ruler: Great for general length, width, and rise measurements. Make sure it has clear inch markings.
- Caliper (Digital or Manual): This one’s key. Tape measures just don’t cut it when measuring handlebar diameter, which needs to be precise for risers and controls.
- Level or Square: Helps you get a true vertical or horizontal reference, especially for rise and pullback measurements.
- Marker or Tape: To mark points on your bars for consistent measuring.
Step-By-Step Guide
- Prep Your Bars: For the most accurate readings, take the bars off your bike or at least loosen the clamps so you can place them on a flat surface. Measuring while mounted often leads to errors because of curves and angles.
- Measure Diameter: Use your caliper to measure the bar diameter at the clamp area and at the grip ends if they vary. This ensures you get a bar that fits your risers and controls perfectly.
- Overall Width: Lay the bars flat and measure the distance from the outer edge of the left grip to the outer edge of the right grip. Follow the curves carefully for accuracy.
- Center Width: Find the straight, clampable section of the bar and measure its length. This is important for mounting and for fitting fairings if you have them.
- Rise (Height): With one end flat on a surface, measure vertically from that surface up to the highest point of the grip area.
- Pullback (Sweep): Still with one end flat, measure horizontally from the surface (or wall) to the furthest point the grips sweep back toward the rider.
- Riser Spacing: Measure from the center of one clamp section to the center of the other. This will confirm if your bars will fit your risers without adapters.
Common Mistakes to Avoid
- Skipping the Caliper for Diameter: Tape measures can’t accurately measure tubing thickness. Always use a caliper here.
- Ignoring Grip Ends: Your overall width should include the full grip length, especially if you plan on using oversized or custom grips.
- Measuring Bars While Mounted: The curves and angles throw off accuracy. Loosen or remove bars for the best results.
- Not Considering Riser or Clamp Hardware: Remember, riser spacing and clamp type affect fit.
Accurately measuring your handlebars might sound like extra work, but it’s what makes your upgrade go from a guessing game to a confident, precise fit. When you know your exact measurements, you can shop smarter, avoid costly mistakes, and most importantly, ride more comfortably.
Why Handlebar Size Isn’t Just About the Bars: Cable, Brake Line, and Wiring Extensions
One of the biggest surprises when upgrading your Harley handlebars is realizing it’s not just about swapping bars. Especially if you’re going for a taller or wider style, you’ll almost always need longer clutch cables, brake lines, and wiring extensions. This part can catch many riders off guard — myself included the first time I did a big bar swap.
The 12-Inch Rule
A good rule of thumb is if your overall handlebar height (bar plus risers) goes over about 12 inches, you’ll likely need to replace or extend your cables and wiring. Why? Because stock components just won’t reach or will be stretched dangerously tight, which isn’t safe.
For example, on a 2020-2024 Low Rider S:
- At 12.5 inches overall height, you’d need a 38-inch upper clutch cable, a 26-inch brake line (with an adapter), plus 6-inch extensions for both switch and throttle-by-wire (TBW) harnesses.
- Bumping up to 13.5 inches means even longer parts: a 40-inch clutch cable and a 28-inch brake line.
What This Means for You
This isn’t just about buying parts — it’s about extra work. Longer cables and wires need to be routed carefully so they don’t kink, bind, or stretch when you turn the handlebars lock-to-lock or compress the suspension. A poorly routed cable can cause serious control issues or damage.
If you’re a DIY enthusiast, this adds a layer of challenge. If you’re going to a pro mechanic, expect added labor costs.
Extension Options
Thankfully, there are plug-and-play wiring extensions from brands like Namz, which avoid cutting or splicing and reduce electrical problems. Harley-Davidson also sells genuine extensions.
But whether you go aftermarket or OEM, planning for these extra components is crucial. The real cost of a handlebar upgrade goes way beyond just the bars themselves.
Compatibility Considerations: TBW, Fairings, and Risers
Modern Harleys often have throttle-by-wire (TBW) systems that require bars with special notches or slots for the TBW sensors and wiring. Many aftermarket bars say if they’re TBW compatible, so keep an eye out for that if your bike has it.
Also, if you have a touring model with big fairings like the Road Glide or Street Glide, handlebar width and pullback must allow clearance. Some bars, like Klock Werks KlipHangers, are made narrower to fit inside fairings. Note that Harley keeps updating fairings, so bars that fit older models might not fit the newest ones without issue.
Finally, riser compatibility matters. Bars need the right clamp diameter — 1-inch, 1.25-inch, or 1.5-inch — matching your risers. And riser spacing is key: most Harleys use 3.5 inches center-to-center, but Springer front ends use 4.75 inches.
Thinking of upgrading your bars? Don’t just think about how they look. Take these compatibility and installation details seriously to avoid surprises.

Wrapping It Up: Handlebar Size Matters More Than You Think
Changing your Harley-Davidson handlebars is a lot more than just picking a style you like. It’s about comfort, control, and making sure everything fits and works safely. From diameter and width to rise, pullback, and riser spacing — every measurement matters.
Measure Twice, Order Once
One tip I can’t stress enough is to measure your current bars carefully before ordering anything new. Use a caliper for diameter, a tape measure for width, and check rise and pullback on a flat surface. This takes some time but saves headaches later.
Expect More Than Just the Bars
If you go bigger or taller than stock, plan for longer cables, brake lines, and wiring extensions. Routing them correctly is a must. Whether you do it yourself or hire a mechanic, this adds time and cost to your project.
Stay Legal and Safe
Before you buy, check your local laws on handlebar height. Some places have strict limits, and getting caught with bars that are too tall could mean fines or worse. Safety first, always.
