WORX Tank Extenders – Why This Should Be Your Next Upgrade

It’s always the little things that make a big difference on a motorcycle. Sure, power upgrades and exhaust swaps grab the spotlight, but if you’ve ever spent serious seat time on the track or twisties, you know rider connection matters just as much as horsepower. That’s exactly why we’re stoked about our WORX Carbon Fiber Tank Cover Extenders. With two current designs, one for the Kawasaki ZX-4RR and ZX-4R, and the other for the Suzuki GSX-8S and GSX-8R, we firmly believe these are one of the most important upgrades you may be overlooking.

If you own either of these bikes, chances are you already appreciate their capabilities. The ZX-4RR is a track-focused scalpel in a lightweight chassis, and the GSX-8R is Suzuki’s sharpest new entry into the middleweight sportbike market. Both are fun as hell in stock form, but they also leave room for improvement, especially when it comes to how the rider fits on the bike. That’s where this upgrade comes in.

Let’s start with the why. From a rider’s perspective, body positioning is everything. Whether you’re setting up for a fast corner or tucking in for a straightaway, the ability to lock in and maintain that position without constantly adjusting makes you faster, smoother, and more confident. Our carbon fiber tank cover extenders were designed with exactly that in mind.
For the ZX-4RR and ZX-4R, Bart focused on creating a clean, functional solution that gives your inner thighs and knees more consistent contact with the tank during aggressive riding. The extender adds extra surface area and alters the tank profile in a way that helps reduce rider fatigue and allows for stronger body anchoring. On the GSX-8R and 8S, he took the same rider-first approach. The tank profile is a bit different, but the goal was the same – extend the usable area and provide you with more control over your body input during hard braking, corner entry, and transitions.

Both units are made from real carbon fiber – lightweight, strong, and designed to blend seamlessly into the tank’s OEM lines. This isn’t just something we slapped on for looks. These parts were CAD designed, 3D scanned, and rigorously tested to make sure they didn’t just fit, they enhanced. And yes, they look damn good, too. The carbon weave pops in the sunlight and adds a subtle performance aesthetic that sets your bike apart without being loud about it.

One of our favorite things about this kind of mod is how much it adds to the ride without requiring a major overhaul. Installation is simple, the weight is negligible, and the benefits are immediate. If you’ve ever found yourself sliding forward under braking or searching for a better anchor point, you’ll feel the difference right away. At the end of the day, upgrades like this are about refining your connection with the bike. It’s one of those mods that reminds you why we love riding in the first place. It’s all about the pursuit of a better line, a smoother transition, and that feeling of being totally dialed in.

So if you’re looking for your next upgrade that actually improves the way your bike rides, not just the way it looks, a WORX Carbon Fiber Tank Cover Extender might just be it. Whether you’re ripping laps on your ZX-4RR or carving canyons on your GSX-8R, this is the kind of upgrade that helps you ride better, feel stronger, and push harder. And really, isn’t that what it’s all about?
