Hyosung GT125R AND GT125 Comet

The hyosung gt125r and gt125 comet is one of the most popular entry-level sports bikes on UK roads, and if you’re looking to give yours a proper performance upgrade, you’ve come to exactly the right place. At Max Torque Cans, we’ve developed a bolt-on performance exhaust specifically designed for the Hyosung GT125R and GT125 Comet 2006 onwards, delivering a genuine improvement in sound, style, and overall riding experience without any complicated modifications or specialist fitting knowledge required.

Whether you’re a new rider looking to personalise your machine or an experienced motorcyclist who wants to extract a little more character from the GT125 platform, this performance can is the ideal starting point. Built with quality materials and precision-engineered fitment in mind, our exhaust for the Hyosung GT125R and GT125 Comet is designed to bolt straight onto your existing setup — no cutting, no welding, and no headaches.

Why Upgrade the Exhaust on Your Hyosung GT125R and GT125 Comet?

The standard factory silencer on the hyosung gt125r and gt125 comet does a perfectly adequate job of keeping things quiet and keeping emissions in check, but it doesn’t do much for the soul of the bike. Swapping it out for a quality aftermarket can transforms the ride. You’ll notice the difference the moment you fire the engine — the exhaust note opens up, the bike feels more alive, and the overall aesthetic of your GT125 takes a significant step forward.

Beyond the sound and looks, a well-fitted performance exhaust can also contribute to a marginal reduction in weight compared to the heavy OEM silencer, which helps with overall bike handling and feel. For a lightweight 125 sports bike, every kilogram counts, and our can is built to be both robust and efficient in its construction.

Fitting the Performance Can to Your Hyosung GT125R and GT125 Comet

One of the standout advantages of this product is just how straightforward the fitting process is. Because this exhaust has been engineered to match the exact specifications of the hyosung gt125r and gt125 comet, it slots directly onto the standard OEM downpipes without any cutting or custom fabrication.

Here’s a general guide to fitting your new performance can:

• Allow the engine and existing exhaust to cool completely before you begin — safety first
• Remove the stock silencer by unbolting it from the downpipe flange and releasing the exhaust hanger rubber
• Offer up the new can to the downpipe, ensuring the 4-bolt flange aligns correctly
• Attach the stainless exhaust strap using the supplied rubber to the pillion grab rail or relevant mounting point
• Tighten all bolts evenly and progressively — avoid over-tightening on the first pass
• Start the engine and check for any leaks around the flange joint before heading out

Most riders with basic mechanical ability and a standard set of tools can complete this job in well under an hour. If you’re ever unsure, a local motorcycle workshop will have this fitted in no time at all. The direct-fit design of this can for the hyosung gt125r and gt125 comet means there’s minimal risk of fitting errors when following the steps carefully.
