KTM 790 S ADVENTURER 2019-2021

If you own a ktm 790 s adventurer 2019-2021, you already know what a brilliant all-rounder it is straight from the showroom floor — but there’s one area where even the most loyal KTM rider will admit the factory setup falls a little flat, and that’s the exhaust note. This MTC performance slip-on silencer has been engineered specifically for your machine, delivering a deeper, more characterful soundtrack alongside genuine performance gains that you’ll feel every time you twist the throttle.

Whether you’re carving through Welsh valleys, commuting through stop-start city traffic, or setting off on a multi-day European tour, this exhaust upgrade transforms the riding experience without compromising reliability or day-to-day practicality.

At Max Torque Cans, we’ve spent years refining our product range to ensure every exhaust we sell meets the exacting standards British riders expect. Our MTC slip-on for the KTM 790 Adventure S isn’t just about volume — it’s about quality of tone, optimised gas flow, and a professional finish that sits naturally on the bike as if it rolled out of the factory that way.

Every component is hand-finished, carefully inspected, and designed to withstand the unique challenges of riding in the UK, from salty winter roads to the relentless rain that tests even the toughest stainless steel.

What’s Included with Your KTM 790 S Adventurer 2019-2021 Exhaust Package

We believe in giving you everything you need for a clean, hassle-free installation right out of the box. No hunting for obscure fittings, no improvising with cable ties and hope — just quality components that work together exactly as they should. Here’s the full breakdown of what arrives when you order your ktm 790 s adventurer 2019-2021 performance exhaust from Max Torque Cans:

• 1 x MTC Exhaust Silencer (380mm) — proportioned to sit neatly beneath the tail unit without overwhelming the bike’s purposeful adventure aesthetic
• 1 x CNC Mandrel Bent Link Pipe with Integrated Heat Shield — precision-engineered for optimal exhaust gas flow and finished to a standard you’d expect from premium OEM parts
• 2 x Stainless Steel Connecting Clamps — robust, corrosion-resistant hardware designed to deliver a gas-tight, rattle-free connection every time
• 1 x Stainless Exhaust Strap — long-lasting support bracket engineered to handle vibration and thermal cycling without cracking or corroding
• 1 x Exhaust Strap Rubber — absorbs engine vibration and protects the silencer body from wear and movement over time
• 1 x Stainless Exhaust Hanger — keeps the entire assembly correctly positioned and securely mounted to the bike’s subframe

Every single component is crafted from high-grade stainless steel, chosen specifically for its resistance to the kind of punishment British weather dishes out year-round. This isn’t a summer-only accessory — it’s a serious upgrade built to handle everything from coastal salt spray to grit-laden winter roads without losing its lustre or structural integrity.

Fitment and Compatibility for the KTM 790 S Adventurer 2019-2021

This slip-on exhaust is a direct-fit replacement designed exclusively for the ktm 790 s adventurer 2019-2021 model range, covering all production years from launch through to the final 2021 machines. The link pipe and silencer assembly are engineered to match the original factory mounting points precisely, meaning there’s no drilling, no modifying, and no fabrication required — just a straightforward swap that any mechanically confident rider can tackle at home with a basic toolkit.

The CNC mandrel-bent link pipe is central to this exhaust’s performance advantage. Unlike cheaper press-bent alternatives that crush and narrow the internal diameter at every bend, mandrel bending maintains a consistent bore size throughout the entire length of the pipe. This allows exhaust gases to exit the combustion chamber and flow through the system with minimal restriction, which translates directly into sharper throttle response, smoother power delivery across the rev range, and a noticeable improvement in mid-range grunt — exactly where adventure riders spend most of their time.

The integrated heat shield is a thoughtful addition that protects both rider and pillion from uncomfortable radiant heat, especially during slow-speed manoeuvres or stationary moments when airflow isn’t there to carry warmth away. It’s a small detail that makes a tangible difference on longer rides or when you’re carrying luggage close to the exhaust outlet.

If you’re also considering upgrades for the R variant of this platform, we stock a dedicated performance exhaust engineered specifically for that model — take a look at our KTM 790 R ADVENTURER 2019-2021 page for full technical specifications and fitment details.

Installation Notes for Your KTM 790 S Adventurer 2019-2021 Performance Exhaust

Fitting this slip-on silencer is well within the capabilities of most home mechanics, and you should have the job wrapped up within an hour if you work methodically. Here are our top tips for a smooth, professional-looking installation:

• Always work on a cold engine. Exhaust components retain heat far longer than you’d expect, so give your bike plenty of time to cool down before you start loosening bolts.
• Use penetrating fluid generously. If your bike has seen a few winters or salty coastal rides, some fasteners may be reluctant to move. A good soak with quality penetrating oil will save you a lot of frustration and reduce the risk of shearing bolt heads.
• Tighten connecting clamps gradually and evenly. Alternate between bolts to ensure even pressure around the joint, and don’t over-torque on the first pass — work up to full tightness in stages to avoid distorting the clamp or crushing gaskets.
• Check all fittings after your first ride. Thermal cycling causes components to settle and seat themselves slightly differently. A quick post-ride inspection ensures everything remains correctly torqued and aligned.
• Consider an ECU remap for maximum gains. This exhaust delivers noticeable improvements straight out of the box, but pairing it with a professional fuel map or a quality fuel management module unlocks its full potential. Motorcycle News provides excellent guidance on optimising performance upgrades like exhausts and fuelling adjustments.

The entire process is straightforward, well-documented, and genuinely rewarding. Once fitted, your ktm 790 s adventurer 2019-2021 will feel sharper, sound more purposeful, and respond to throttle inputs with an eagerness that reminds you why you bought an adventure bike in the first place.
