The all-new 2026 KTM SX-E 2.12 takes all the best parts from the KTM SX-E 2, but steps it up with a taller frame, bigger 12" front wheel, and extended suspension. This makes it perfect for little beginners who are on the slightly bigger side.
Using the full-sized KTM SX range as a guideline, the KTM SX-E 2.12 features modern, striking graphics in typical "big bike" fashion. All graphics are also applied using an in-mold process, ensuring the best durability and quality for many years of off-road action.
BIG BIKE DESIGN
CHASSIS
Built tough to last, the KTM SX-E 2.12 chassis boasts an impressive list of construction materials. The upper triple-clamp, handlebar clamps, footrest carrier, and brake components are made of high-end forged aluminum alloys, while the lower triple clamps and the shaft are crafted from forged chromoly steel. The swingarm and skid plate complete the list, made from HPDC aluminum alloy.
BUILT TOUGH
FRAME
The KTM SX-E 2.12 features a slightly modified version of the center tube Aluminum Extrusion Frame design found on the KTM SX-E 2. Constructed from High-End Aluminum alloy, this frame strikes the perfect balance between strength and safety, while the high-quality glass-fiber reinforced subframe features an impact-resistant plastic composite for low weight and shock absorption.
ALL-OUT ACTION
SUSPENSION
The KTM SX-E 2.12 boasts a non-adjustable, WP regular Hydraulic Fork with a slightly longer range compared to the KTM SX-E 2. This extends the proportional elements of the platform, while maintaining a preload-adjustable 34 mm Hydraulic-mono-shock with separation piston on the rear.
MASTER THE TRACK
WHEELS AND TIRES
If you were wondering what the last two digits in SX-E 2.12 referred to, it's the 12" front wheel matched to a 10" rear, setting it apart from the KTM SX-E 2. Made from lightweight aluminum, both HPDC rims, front and rear, are powder-coated to provide trouble-free maintenance, while a set of exceptionally well-balanced motocross tires from KENDA provides ample grip.
BALANCE POINT
INCREASED SEAT HEIGHT
The KTM SX-E 2.12 is aimed at bigger beginners with a 2.59 in (66 mm) taller seat height when compared to the KTM SX-E 2. This was achieved by increasing the bench thickness, chassis dimensions, and bodywork to better in line with overall proportions.
STOPPING POWER
BRAKES
Slightly longer brake lines are added to fit within the larger proportions of the KTM SX-E 2.12. These sent fluid to a set of radial, hydraulic 140 mm disk brakes on the front and rear, ensuring ample stopping power when the going gets too fast. Also, the hand levers are adjustable to fit smaller hand sizes, with the brake pads being compatible with high-end market bicycle brake pads for easy availability.
PERFECTLY MADE TO MATCH
CONTROLS
The black anodized, aluminum alloy handlebars feature 25 mm bar raisers, but maintain a reduced diameter grip area for the perfect ergonomic grip for little hands. The width and bend were also specifically developed for easy steering while ensuring a firm grip and control of the KTM SX-E 2.12.
EASY TO HANDLE
LIGHT WEIGHT
Weighing in at only 29 kg, the KTM SX-E 2.12 feels like a real, bigger motorcycle, while still providing easy handling. The combination of weight and agility provides a planted, more secure feeling as the speed builds, and is better suited to bigger, harder bumps.

CHARGED UP
MOTOR AND POWER
Providing the forward drive for the KTM SX-E 2.12 is a lightweight, maintenance-free 1,8 kW HUB Motor which delivers a maximum of 50 Nm. The "HUB-Motor-Concept" is void of additional parts like chains or sprockets, helping to keep the weight low and providing extra safety in the event of a crash. The controller is also integrated within the motor packaging, guaranteeing a spontaneous, but controllable power delivery.
CHARGED UP
CHARGER
An external charger supplying up to 500 W can be connected to any 110- or 230-Volt socket and plugs directly into the battery pack for easy charging. Charging time from 0 - 80% take approximately 35 minutes, with a full 100% charge achieved in less than 60 minutes.
STAY SAFE
SAFETY
Making sure your little ripper is safe is a top priority. For that reason, the KTM SX E-2.12 is fitted with a roll-over sensor that cuts power in the event of a crash or tip-over. A wrist lanyard key also provides a direct connection between the riders and the kill switch, which stops the motor in the event of an uncontrollable riding scenario.
PICK YOUR POWER
MULTIFUNCTIONAL THROTTLE
As an added safety feature to ensure the KTM SX-E 2.12 doesn't pull away without warning, the electric motor is activated by rolling the throttle forward. Once on, a haptic 'vibration' is sent through the grip, indicating to the rider that the bike is ready to go. This and an illuminated multifunctional display located next to the throttle, makes keeping an eye on selected ride modes and battery life is a breeze, with different colors indicating which ride mode is selected, as well as what level the battery is at.
KEEP GOING
QUICK CHANGE LITHIUM-ION BATTERY
Powering the KTM SX E-2.12 comes courtesy of a 9.4 Ah, Lithium-ion power-tool-type battery with proven longevity and robustness, boasting 1500 charging cycles and up to 100 minutes of riding time. However, the real perk comes with the ease of swapping the battery with one easy movement, providing advantages like anti-ride protection, extended ride time with multiple batteries, and easy battery replacement in case of damage. Moreso, all units are rated IP65 and perfectly protected from wet conditions.
