2023 KTM 125 SX Dirt Bike – Features and Specs

Electric Start

Picture this: you’re seven laps into an incredible ripper of a race. You miss your line and wind up stopping in a deep rut. But you don’t sweat it. All you do is push the begin button and blast off again to grab the last flag. It is the truth on the 2023 KTM 125 SX. Thanks to the powerful 12.8V 2 Ah lithium-ion battery mounted beneath the rider’s seat, a new high-quality stator and pickup, and highly sturdy construction, the days of kick-starting are past.

Easy Suspension Adjustment

Become focused! The 2023 KTM SX series has an entirely tool-free suspension setting at both ends. Riders can modify high- and low-speed settings in seconds thanks to an all-new shock absorber design incorporating hand-adjustable dual compression control. On the front end, the forks are likewise readily changed thanks to a single air pressure preload valve and quick access click adjustments for compression and rebound. We’ll even throw the air pump in as standard.

Electronic Fuel Injection

Pre-mix is remixed throughout the 2-stroke KTM SX line, with electronic fuel injection as the norm—the jetting setup before the race has been discontinued. Additionally, you may be sure you’ll always put down the most power possible at any altitude because of the brand-new Keihin EFI and reed valve case design.

Electric Start

Imagine this: you’re seven laps into a fantastic race. You become stuck in a deep rut when you fail to correct your course. But you’re not worried about it. To continue your pursuit of the last flag, you only have to push the launch button. The truth about the 2023 KTM 125 SX is as follows. The need to kick start the motorcycle is obsolete due to the inclusion of a 12.8V 2 Ah lithium-ion battery beneath the rider’s seat, a brand new high-quality stator and pickup, and a highly sturdy construction.

Easy Suspension Adjustment

Bring it in! The front and rear suspension of the 2023 KTM SX models are adjustable without the need for any tools. Thanks to a brand-new shock absorber design with hand-adjustable dual compression control, riders may quickly and easily switch between high- and low-speed settings. The front forks include a single air pressure preload valve and click adjustments for both compression and rebound that are conveniently located and simple to use. We’ll consist of the air pump at no extra cost.

Start Strong Selectable Maps

Once again, slicing into the 125cc class with the cutting edge of technology, the 2023 KTM 125 SX includes a map choice button enabling the racer to switch between two engine maps.

EFI and Power Valve

With EFI comes unique rideability along with the electronic fuel injection, an all-new power valve has been put into the KTM 125 SX, providing greater useable power across the rpm range. Smoother power equals improved traction. The increased grip is a hole-shot champion’s dream.

Performance

The new 2023 KTM 125 SX is built to produce greater torque than any 125 cc 2-stroke engine before it, and it intends to maintain its lead in the segment. This lightweight powertrain packs a punch where it counts while maintaining the characteristically high-revving nature of its lightweight design (the engine weighs just 39.3 lb. altogether).

Selectable Maps

Once again, slicing into the 125 cc class with the cutting edge of technology, the 2023 KTM 125 SX includes a map choice button allowing the racer to switch between two engine maps.

Mass Centralization

The 2023 KTM 125 SX engine strongly focuses on mass centralization, with a rotating mass center location for best chassis integration. The result is the most formidable 125 cc moto crosser, thanks to its reduced weight, improved agility, increased torque, and smooth power delivery.

Absolute Control

An all-new frame design built for longitudinal stiffness and repositioning rotational mass closer to the center of gravity will allow you to maintain complete control no matter how rough the track becomes. The foot peg mounting location has been shifted inward to reduce the possibility of hooking up in deep ruts or while scrubbing jumps. A redesigned shock mounting improves anti-squat behavior for more excellent traction out of corners.

Ergonomics

Upgraded knee contact, especially while standing on the pegs, and additional gripping surfaces characterize the 2023 KTM SX and SX-F range’s revised and upgraded rider triangle. The modified, flatter seat profile and high-grip seat cover allow for unparalleled rider mobility and control in wet, muddy situations while the new polymers work to expel muck accumulation. The aluminum subframe is strengthened with polyamide, significantly improving the rider’s connection to the bike.

Stability

The 2023 KTM 125 SX’s redesigned and forged steering head connection and its CNC machined triple clamps make it incredibly stable at high speeds. These are made of high-quality aluminum and have a steering stem with a stiffness that has been fine-tuned to provide a smooth and responsive ride, as well as fork tubes that are perfectly aligned and a fork clamp geometry that guarantees you won’t lose your balance as you charge through ruts in pursuit of a podium finish.

Traction

Is it time to yank your shoulders out of their apertures? Changing the steel frame idea has several positive effects on the chassis, including centralizing the vehicle’s mass and making it seem lighter overall. The 2023 KTM 125 SX expertly transmits power to the ground for ferocious acceleration out of turn.

WP XACT Data Air-type 48-millimeter fork: Thanks to the WP XACT front fork’s split damping feature, you can confidently take on the track. When confronting large jumps, bumps, and thumps, the new hydro stops in the fork legs increase bottoming-out resistance and account for a reduced rebound. Fork rings have been redesigned to provide even more protection from dirt, making them dependable and fantastic.

Consistency

Featuring low-friction SKF linkage seals and enhanced damping characteristics for superior traction and energy absorption, the new WP XACT shock absorber delivers unrivaled consistency lap after lap.

Energy Absorption

The hydro-formed, laser-cut, and robot-welded frame has been carefully built with carefully calculated longitudinal and torsional flex characteristics to ensure significant rider input and straight-line stability. To put it another way, the frame functions as a “shock absorber,” softening the blows and reducing the wear and tear on the rider over many long loops.
