A rally-shaped silencer on a supermoto. Spark's Dakar slip-on takes 2,4 kg off a 690 SMC R, and Spark lists it as available while stocks last.
Key Features
- Racing slip-on for the KTM 690 SMC R, 2021 to 2023.
- Dakar silencer in dark style with a connecting pipe.
- 2,1 kg against 4,5 kg standard: 2,4 kg saved.
- No road approval — closed-circuit use only.
- Available while stocks last.
- Made by Spark in Mantova, Italy.
More Than Half the Weight
4,5 kg becomes 2,1. On a single-cylinder supermoto of around 147 kg dry, taking 2,4 kg off the silencer is a proportion that is felt rather than argued about — and it comes off high and to one side, which on a bike ridden on its side is exactly where it counts.
The Dakar Shape on a Supermoto
Spark drew the Dakar around the desert rally: a plain squared case, no carbon cap, no ribbing. On the 690 SMC R — a machine Spark describes as versatile for every kind of road, on and off it — the shape suits the bike's own stripped-back character.
The finish is dark style, an electrochemical colouring of the metal rather than a coating, so a stone strike does not take a layer off.
Available While Stocks Last
Spark marks this article as available while stocks last. That is the manufacturer's own note and it means the number is being run out rather than restocked — if you want one, do not plan around it being there next season.
Track Use Only
Spark lists the slip-on as racing. There is no homologation certificate, and it must not be fitted to a motorcycle used on public roads.
A Note on the Price List
Spark's 2026 price list describes this entry as a slip-on for the KTM 890 and Norden 901, while the article page for the same number is unambiguously about the 690 SMC R. We follow the article page, as we do wherever the two disagree — but if you ride an 890 or a Norden and want this silencer, ask us and we will confirm it with Spark first.
What Comes Off
The standard 690 SMC R silencer is a steel can under a pressed shield, sized around the noise regulation rather than around the motorcycle. Spark replaces it together with its connecting pipe; the manifold and the catalytic converter stay where KTM put them.
Fitting is well under an hour with hand tools, and nothing needs re-mapping afterwards.
Dark Style, and Why It Matters Here
An electrochemically coloured surface is part of the metal rather than a layer over it. On a supermoto that gets dropped in car parks and ridden down gravel tracks, that is the difference between a scuff and a bare patch.
It also suits the bike: KTM finishes the 690's frame, subframe and swingarm dark, and a bare metal silencer would be the only bright object at the back.
Fitment & Compatibility
KTM 690 SMC R, 2021 to 2023, per Spark's own article page for this number.
Road Approval
None. Spark lists this part as racing; it is built for closed-circuit use and must not be fitted to a motorcycle ridden on public roads.
