I’m on my second KTM.
My first was a 2023 KTM 890 Adventure—just the standard model, not the 'R'. It was a fantastic machine. I absolutely loved the power, the sharp handling, and how incredibly low it kept its center of mass.
What I didn’t love was how often it broke.
To be completely fair, during my short 16 months of ownership, it never actually left me stranded. But it did require a steady stream of small repairs. First, the front brake master cylinder cover started leaking. Then, the valve cover gasket wept oil. Next, the brake light failed.
Unlike most bikes I’ve owned, KTM doesn't use a simple mechanical micro-switch at the brake lever. Instead, they route a pressure switch all the way down near the ABS pump. It’s not a massive deal structurally, but to fix it, you have to strip the bike down and remove the gas tank—which is a distinct pain in itself. Then you have to bleed the entire brake system, all just to replace a tiny switch.
Then there were the turn signals. They would fail intermittently, forcing me to pull over and cycle the key just to get them working again. Rather than chase that electrical ghost forever, I decided I’d had enough. I traded the 890 in on a Yamaha Tracer 9 GT+ and figured I’d live happily ever after.
Well, almost.
The Tracer vs. The "Rowdy" Factor
That KTM bug bites deep. My Yamaha is a truly wonderful motorcycle. After getting the ECU flashed, it makes great power and feels incredibly sophisticated and competent. But by contrast, the 890 Adventure felt raw. Rowdy, even. After a while, I realized I missed that unrefined edge.
So, I bought a 2026 KTM 390 SMC R.
Years ago, I owned a Yamaha WR250X. As a supermoto, that bike was pure fun. It wasn't great as an only motorcycle, but it was absolute magic for blasting around town. It was always a game of trying to maintain momentum through the corners, and the beauty of it was that you could completely wring the bike's neck without breaking a dozen traffic laws. I missed that exact feeling, and that’s what led me to the SMC R.
Meet the New 399cc Blender
The 390 SMC R has way more punch than the old WR250X ever did. It features a lower, more accessible seat height, and it is absolutely brimming with KTM’s trademark, in-your-face attitude. At lower revs, the new LC4c single vibrates like a blender full of pebbles. The real power is made way up high in the rev range where, thankfully, the vibrations finally smooth out.
I did run into a few issues right upon delivery, but I’m convinced the majority of those headaches were down to a dealer that did an awful job with the Pre-Delivery Inspection (PDI). After three separate attempts, they finally got the bike sorted out.
But even bone stock, the new 390 platform has some inherent quirks. Strict Euro 5+ emissions standards mean the bike runs incredibly lean right out of the factory—so lean that it can barely maintain a smooth idle. Low-RPM power is practically non-existent, which makes tooling around town feel like a chore.
Uncorking the Single
Since I am entirely incapable of leaving well enough alone, the modifications started early.
I installed a Coober LM fuel controller alongside their DeCat header pipe, which runs directly from the cylinder head into the stock breadbox muffler. To let it breathe on the intake side, I added a DNA Stage 2 filter and high-flow airbox lid.
These modifications completely transformed the bike. They injected some much-needed power and smoothness into the bottom end, making it infinitely more ridable. And at full throttle? The aggressive roar echoing right through that intake is absolutely awesome.
The Yamaha might be the sensible choice in the garage, but the rowdy little KTM is the one that puts the smile on my face.
