Top Upgrades For Your Sportster S
Sportster S By Harley-Davidson®
If you’ve got your hands on a Harley-Davidson Sportster S, you already know it’s a beast straight out of the box, But let’s be real—there’s always room to make it even better.Â
Whether you’re chasing more horsepower, sharper handling, or just want to dial in the look to match your personal style, with the right upgrades you’ll take your Sportster S to a whole new level.
In this article, we’ll cover some of the best upgrades available to transform your Sportster S into an absolute Beast.
Sportster S - Exhaust Systems
The stock Sportster S exhaust, while functional and emissions-compliant, falls short in the key areas of performance, weight, and sound. Its restrictive design limits airflow, preventing your Revolution Max engine from reaching its full horsepower and torque potential, while the heavy system adds unnecessary weight that affects handling and slows your acceleration. Additionally, the factory pipes produce a tame, muffled sound that lacks the raw, aggressive growl you would expect from your Harley.
Upgrading to a high-quality performance exhaust addresses these shortcomings by improving airflow for increased power and throttle response, reducing the weight of your bike for better handling, and delivering a deeper, richer, more distinctive sound. It also offers your Sportster S an aesthetic boost, giving it a custom look that’ll stand out from the others.

Sportster S - Clutch Upgrades
Upgrading the clutch in your Sportster S is a smart move if you want to maximize performance and reliability. Your stock clutch, while adequate for everyday riding, may struggle under higher loads and aggressive acceleration. Adding performance upgrades like exhausts and air intakes puts extra stress on on a clutch designed for factory power specs.
Â
An quality clutch engineered for high-power, like a Barnett Clutch Kit, provides stronger power transfer to the rear wheel, eliminating slippage under heavy torque or stress.
Â
It also offers smoother engagement, greater durability, and resistance to wear, especially in higher heat conditions. So, If you’re planning to push your Sportster S to its limits — whether on spirited weekend runs, or racing your mates from stop light to stop light — a clutch upgrade ensures your Sportster S can handle the extra power and demands with ease, keeping your bike reliable and responsive.
Sportster S - Lifting & Lowering Kits
Just like with any Harley, you want your Sportster S to reflect your own personality & riding style. Your bike’s ride height is a big part of that. The good news for you and your Sportster S is you can do this easily with a lift or lowering kit made by Kodlin USA.Â
Â
The Kodlin 1” Lowering Kit and 1” Lift Kit are great ways to customize your Sportster S to match your riding style and preferences. The lowering kit gives your bike a sleek, aggressive stance, improves stability at low speeds, and makes it easier to reach the ground, especially for shorter riders. On the other hand, the lift kit raises the rear by 1 inch, increasing cornering clearance for more aggressive lean angles and enhancing the bike’s performance-focused look.
- Lowering Kit: Improves low-speed handling and creates a custom, aggressive stance.
- Lift Kit: Increases cornering clearance for spirited riding and deeper lean angles.
- Durable Construction: Built for reliability and long-term performance.
- Direct Fit: Designed specifically for the Sportster S (2021-up), ensuring easy installation.
Both are easy-to-install modifications that not only improve functionality but also give your Sportster S that personalized touch.
Sportster S - Tail Tidy By TBR
Fitting a Tail Tidy to your Sportster S is a great way to completely change the overall look of your bike’s rear end. The stock rear fender assembly is excessive, clunky and visually distracts from your Sportster S’s streamlined aggressive design.
Â
The TBR Fender Eliminator Kit, streamlines the rear end, giving it a cleaner, more custom look that matches the Sportster S’s modern style.
Beyond aesthetics, this kit integrates run, turn, and brake lights, as well as a number plate light, ensuring you stay visible and road-legal without sacrificing safety. It’s also built with high-quality materials, providing durability and a snug fit for your bike.
Â
Modifying your Sportster S with this Tail Tidy is a no-brainer. It’s a simple change that makes a HUGE difference to your bike’s overall appearance.
Sportster S - Super Cush Drive
This is a hidden gem… the upgrade you didn’t know you need.
Upgrading your Sportster S from the stock cush drive to the Alloy Art Super Cush Drive is a game-changer. The stock cush drive does its job, but it wasn’t built to last or handle the kind of torque or aggressive riding this bike encourages.
The Alloy Art version absorbs shocks and bumps better, smoothing out power delivery and reducing stress on your transmission, rear hub, and belt. It’s made from tougher materials, so it lasts longer and performs more consistently, even when you’re pushing the bike hard.
You’ll notice less vibration, smoother shifts, and a more connected feel between the throttle and the rear wheel — Delivering responses beyond what it would normally provide.
This small upgrade makes a big difference, keeping your Sportster S running smoother and stronger for the long haul.
Sportster S - Brake Upgrades From GBrakes
The Sportster S flies—that’s exactly why you bought it, because you love speed. But the faster you go, the longer it takes to stop. To truly maximize the performance of your Sportster S’s calipers, we recommend GBrakes Wave Rotors. Available for both front and rear fitments, these rotors do more than just enhance your bike’s aesthetics—they’re a significant upgrade in braking performance and handling.
Here are some of the reasons why these rotors are a MUST for your Sportster S:
