Exhausts Ktm 890 SMT 2023-

The LC8c parallel twin engine with 889 cc is the heart of a project that KTM built around a precise concept: bringing the supermoto soul to the road without giving up range. The 890 SMT is built on a chromoly steel frame with the engine as a stressed member, paired with long-travel adjustable WP suspension and a chassis designed for fast mixed roads and mountain passes, not just transfers. It's a bike you ride, not one that rides you. For those who want their exhaust to play its part too, our exhausts for KTM are developed to fit this philosophy without compromise.

The product in this category is a replacement silencer with lateral positioning, designed to replace the stock muffler on the 890 SMT. This is not a full exhaust system: the original headers and downpipe remain in place, as does the catalytic section required by Euro 5 regulations. The intervention focuses on the end can, which is removed and replaced with ours using the mounting kit included in the package. The fittings are compatible with the original specifications, so no modifications to the exhaust system structure are required. For installation, we still recommend entrusting the work to a qualified mechanic, who can check torque, sealing and correct positioning.

The most immediate benefit is weight: the stock end can tends to be oversized relative to actual acoustic and flow requirements, with materials and volumes designed to absorb homologation tolerances rather than optimise performance. Our silencer significantly reduces weight in that area of the bike, with a positive effect on mass distribution as well. On the sound side, the tone is fuller and more defined than the original, with a more characterful note in the mid-range and greater presence under acceleration. Since the catalytic section of the original header remains in place, the effect on sound is an improvement but contextual to the Euro 5 setup: expect a clear change from stock, not an extreme volume increase. In terms of throttle response, the change in back pressure and flow management can favour a more linear response, particularly in the mid-to-high rev range most used in mixed riding; in some configurations it can translate into a feeling of greater responsiveness.

Every silencer we ship is handcrafted in our workshop with handcrafted manufacturing in Lombardy, in the province of Bergamo. Each piece is made to order and undergoes internal quality control before leaving the production department. We work direct from the manufacturer, meaning there is no intermediate step between the person who builds the part and the person who receives it.

The 890 SMT's ECU does not normally require remapping or electronic intervention for a end can replacement only. The engine management system is able to adapt within the margins provided by the platform, without any changes to the base map being necessary.

The dB killer is included as standard with every silencer. Its removal is not officially provided for: it results in the loss of homologation and road use of the vehicle becomes non-compliant. Keeping it fitted is the correct choice for anyone using the bike on public roads.

Updated production times are visible directly at checkout, as they may vary depending on the period. Tracking is sent automatically by email as soon as the package is handed over to the courier.

For any questions about compatibility, finishes or available options, you can consult the FAQ section of the website or contact us via the Contact page or chat: we respond in a direct and technical manner.

In the product list below you will find all available silencers for the KTM 890 SMT 2023 and later. The differences between models are mainly aesthetic: body shape, material (stainless steel, carbon, titanium) and surface finish.
