Is the 2022 KTM 125SX better than the 2022?
The biggest complaints about the KTM 125SX were in 2022 when they switched from a 38mm Keihin PWK carburetor to a 38mm Mikuni TMX carburetor. The bike was quite exciting for 2016 with a Keihin carburetor, all-new WP AER forks and a powerful engine. After switching to Mikuni, the low fuel mixture ratio changed, which was now 60:1, whereas on Keihin the ratio was 40:1. In 2018, the 40:1 ratio was returned and the carburetor was slightly retuned. In 2019, KTM sorted out the jets, engine and suspension, and the new 125SX leaves last year's version behind.

What's changed on the KTM 125SX for 2022?
The entire KTM SX lineup gets a makeover for 2022. The frame, air filter, swingarm, plastic body kit, seat, transmission, fuel tank and suspension components were updated. The engines and exhaust pipes have been upgraded especially for the KTM 125SX and 150SX.
Modifications
In addition to the standard version of the KTM 125 Duke, there are modifications of the bike on sale:
- DUKE KTM RC 125 – produced since 2014. As a result of tuning, the wheelbase was reduced, and the frame became stiffer and changed its configuration for a more sporty stance. The front fork travel was changed from 150 to 125 mm, which ensured a more sensitive response of the bike to the rider’s leanings.
- KTM Duke 125 ABS 2022. The difference is the presence of the Antilock brake system, which reduces the braking distance and reduces complete wheel locking. This helps reduce the likelihood of falling if you make a mistake while braking.
- KTM Duke 125 2022 – a slight restyling was made, the model received a more youthful and sporty color (gray-black-orange), the lines were slightly changed (they became more rounded). All technical specifications remain the same.

Design
The manufacturer managed to preserve the characteristic features inherent in the sporty Dukes, and at the same time made changes to make the model more suitable for urban conditions. For example, the KTM Duke 125 tires are atypically wide for a 125 cc bike - 110/70ZR17 at the front and 150/60ZR17 at the rear (narrower “donuts” are usually installed on a mini sportbike).
As for the dimensions, the manufacturers did not make the model too small. For example, the 125 cc bike differs from its older brother (Duke 690) by only 10%. But it was decided to remove the heavy “tail” and the massive saddle so that the motorcycle would not look awkward on city roads.
The rigid frame is made of a “birdcage” type - it has an impressive rear suspension pendulum with massive stiffening ribs. Headlights – halogen 60/55W. The rear brake light and turn signals are LED.
The handlebars of the KTM Duke 125 are wide and offer an almost upright riding position for the driver. The saddle is large, but quite dense, as it should be for a sportbike. Before the pilot’s eyes is a spacious instrument panel with a small LCD display. The switches are backlit, which is very convenient in the dark. The model is available in three colors - black, black-orange and black-red.
Cons of the 2022 KTM 125SX
Preload adjustment ring. There must be a better way to adjust the preload on the rear shock. When everything is new and clean, it can be adjusted with a long screwdriver, but when everything is already dirty, adjustment becomes a problem, and the plastic ring is quite easy to break.
Power valve regulator. The valve is adjusted with a square key. Do you always have it at hand? And if you try to adjust it with a screwdriver, you will no longer be able to put the key on.
Screw for removing air from the fork. The bleeder screw on the right side of the fork is a Torx #15. KTM should go back to the Phillips head screw they used a few years ago.
Knitting needles. They are constantly weakening. Keep an eye on them.
Air filter. You can get more horses and improve throttle response by increasing the air filter capacity.

What is the final drive?
On the 2022 KTM 125SX, everyone changed the rear sprocket from a 50 to a 51 tooth. A year ago the goal was to increase low-end and mid-range torque to aid cornering. For 2022, the KTM's power increase was enough to warrant replacing the rear sprocket - the stock one provides good traction in any gear.
How has the suspension improved since last year?
For 2022, KTM has improved the 48mm WP AER forks with new parts and tweaked settings. Monoshock air pressure has been reduced from 124 psi to 120 psi, and rear spring rate has been lowered from 42 Nm to 39 Nm to match the lighter fork settings. The 39 Nm spring rate works well with riders weighing 75-90 kg. For riders weighing less than 70kg, we suggest lowering the spring rate to 36Nm, while riders weighing over 90kg should revert to last year's spring rate of 42Nm. In general, the suspensions turned out to be balanced even with standard settings.

Model history
In 1934, a small workshop for repairing bicycles and mopeds was formed in Austria. In a couple of years, it grew and began to make its own equipment. In 1954, it received the familiar name “KTM” and became one of the powerful manufacturers of motorcycle equipment in Europe. Since 1965, the company began to gradually reduce its production of bicycles and mopeds, focusing only on sports motorcycles. Until the 1980s, KTM produced copies only for participation in various races (including the Dakar Rally). Since 1983, mass production of civilian versions of KTM sports motorcycles began.
The 125cc model was developed back in 1955. Since then, it has been modified more than once, and each version has invariably been recognized as the best in its class. In 1981, the air cooling system was replaced with a liquid one. Since 1986, KTM bikes have received both front and rear disc brakes. Since 1987, models with a single-cylinder four-stroke engine with an overhead camshaft began to be supplied.
In 2005, the Austrian motorcycle manufacturer entered the post-Soviet market. KTM Duke 125 motorcycles immediately became favorites of Russian and Ukrainian motorcycle enthusiasts. For 15 years now, the model has been considered the best-selling model in the category of naked bikes – sports motorcycles adapted for city roads. In its familiar form (with the current design and internal contents) DUK 125 has been produced since 2011.
Tuning
The appearance of the Ktm 125 Duke for most owners seems quite aggressive and complete, requiring no improvement. However, not everyone thinks so, including the motorcycle manufacturer itself. If you decide to improve your bike, then there is no need to order handmade parts or sculpt handicrafts. Factory modification kits are already waiting for their owners in a special catalog. It has everything from the smallest plastic trim to new seats, rims and other elements. If desired, you can replace up to 80% of the entire motorcycle using only the catalog. There are a huge number of modification options. There are several color options for individual parts.
