A NEW GENERATION TO EMPOWER THE NEXT GENERATION: DISCOVER THE BUZZ OF THE 2025 KTM SX-E’S
KTM is fully charged for the future phases of e-mobility to get youngsters rolling with their first meters on two-wheels and to sharpen their skills to the point where a READY TO RACE mentality becomes a way of life.
The foundation step has been polished, and the new 2025 KTM SX-E mini cross motorcycles represent a benchmark in the industry for the commitment to quality. The KTM SX-E 5 and KTM SX-E 3 might enable hours of fun, learning, and stimulate the early flow of adrenaline but these bikes are not ‘toys’: this is the start of a new era for the next generation of riders and racers.
Here are six ways in which KTM is plugging-in to play with the 2025 KTM SX-E line-up:
Drivetrain development
For 2025 the KTM SX-E 5 has a super-advanced fully electric, water-cooled permanent magnet motor that provides 30% more riding time compared to the previous version and peak power at 5.0 kW. The unit is dust and waterproof which makes it low wearing and maintenance-free, while the integrated control unit (ECU) guarantees a direct but very controllable power delivery. The surge is good enough to guarantee exhilaration for youngsters however it also packs enough to satisfy the demands for racing. In short, a high-quality and real-world READY TO RACE alternative to the petrol-powered 50 cc engine. The KTM SX-E 3 has an air-cooled motor pumping out a manageable 3.8 kW rate but is ideal for smaller riders making their first small-wheel miles. On both bikes a multifunctional instrument display shows the state and charge level of the battery but also one of the six different ride maps that administer how strong and fast the potency of the drivetrain feeds through the throttle.
Frame finesse & “Go as you Grow”
One of the best features of the KTM SX-Es is the adjustable dimensions of the bike. The subframe is made of lightweight, fiberglass reinforced plastic elements, which can be mounted in different positions to suit the changing size of the junior rider. The variance window is 634-682 mm and is hiked up or slid down by easy movements with the seat and bodywork. An even lower seat height can be achieved by dropping the forks down in the triple clamps and by changing the mounting position of the rear shock. The frame is forged from lightweight, high-strength chromium-molybdenum steel for precise agility and stability, but a new 2025 modification provides more robustness, handling, and a tougher rear shock mounting point.
WP Suspension for that factory feeling
The adult bike pedigree means the suspension equipment for the KTM SX-E 5 is formidable. A fully adjustable, upside-down 35 mm WP XACT air fork and 205 mm of travel ensures comfort and confidence. The air spring fitted in the left fork leg can be adjusted perfectly to the rider’s weight using a simple air pump. The WP XACT shock absorber is also flexible (preload, rebound and high and low speed compression) and linked directly to the cast swingarm, providing excellent damping performance with 193 mm of travel. The KTM SX-E 3 is well-equipped but slightly simpler with the non-adjustable upside-down 35 mm WP XACT fork (144 mm of travel) that are nevertheless class-leading for the product. The shock will offer 129 mm of rebuttal.
Battery bounty
The battery on the KTM SX-E 5 is constructed from 84 modern lithium-ion cells in a robust die-cast aluminum casing, harnessing energy for 907 Wh: enough for two hours of a relaxed rhythm riding or 30 minutes of hardcore throttle abuse for race conditions. The KTM SX-E 3 has 60 cells for 648 Wh for a similar rate of riding time but a new cable component means the KTM SX-E 3 can swap and upgrade the battery from its bigger brother, leading to even more time in the saddle. Each bike has an advanced battery management system that administers and preserves the lifecycle of the battery.
Counting the charge
The KTM SX-E 5’s charging time has been reduced, with 0-80% capacity achievable in 45 minutes while 0-100% is possible in just 70 minutes. The external worldwide charger supplying up to 900 W can be connected to any 110- or 230-volt socket. The KTM SX-E 3 will charge from 0-20% in 20 minutes, 20-80% in 100 minutes and to 100% in 140 minutes. Safety? Of course. Both bikes have a rollover sensor that cuts off the power in the event of a fall, while a wrist lanyard cut-off key stops the motor in the event of an uncontrollable riding scenario. Ride modes can be locked and saved with a dongle that can be found under the seat.
The perks of the parts
Outright performance is not the only benefit of both 2025 KTM SX-Es. Each motorcycle comes with a host of outstanding parts so that the bikes sit comfortably in the full all-conquering KTM SX range. Strong, aluminum alloy NEKEN handlebars taper from 28 mm in the central zone to 22 mm in the bend to 18 mm in the handhold areas, enabling the use of a thinner lock-on ODI grip, engineered especially for electric drive. Also, on a theme of strength, the two bikes have light, black anodized, aluminum rims (10” for the KTM SX-E 3 and 12” for the KTM SX-E 5) with MAXXIS MAXXCROSS-ST tires for superb all-round traction across diverse terrain. The wheels are common components through the full-size KTM SX range and another area of shared engineering is the hydraulic brake calipers and wavy discs front and rear. The KTM SX-E 3 has a handlebar-mounted rear brake and the KTM SX-E 5 is foot operated. The design of both KTM SX-Es features the latest in-mold graphics, with a bold orange livery that perfectly sets off the factory-look orange frame, orange seat and race-sharpened, narrow bodywork. READY TO RACE indeed.

FULL KTM SX LOOK
GRAPHICS
Using the full-sized KTM SX range as a guideline, the 2025 KTM SX E-2 features modern, striking graphics in typical “big bike” fashion. The graphics are also applied using an in-mold process, ensuring the best durability and quality for many years of offroad action.
BIG BIKE DESIGN
CHASSIS
Built tough to last, the KTM SX-E 2 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
Built around a center tube Aluminum Extrusion Frame, the 2025 KTM SX-E 2 features a design concept that reduces the number of components needed, to ensure fewer connections for maximum durability and chassis rigidity. It’s constructed from High-End Aluminum alloy, which strikes the perfect balance between strength and handling. The subframe is made from a high-quality glass-fiber reinforced, impact-resistant plastic composite for low weight and shock absorption. Both are painted with a black KTL coating.
ALL-OUT ACTION
SUSPENSION
Ready to tackle the most challenging track conditions, the KTM SX-E 2 boasts a non-adjustable, WP regular Hydraulic Fork with 3.5 Inches travel up front and a preload-adjustable 1.3 Inch Hydraulic-mono-shock with separation piston on the rear with 2.7 Inches of travel. This is mounted to a HPDC Aluminium swingarm, the 1.3 Inch Hydraulic monoshock is matched perfectly to the front forks for exceptional balance and damping characteristics.
MASTER THE TRACK
WHEELS AND TIRES
10″ wheels on the front and back ensure planted handling on all terrain types. Lightweight, black powder-coated aluminum HPDC rims front and rear provide trouble-free maintenance, while a set of exceptionally well-balanced motocross tires from KENDA provide ample grip.
BALANCE POINT
LOW SEAT HEIGHT
Young riders find their feet easily thanks to a 2-level adjustable seat height. In standard configuration, the seat height is 18.5 Inches but can easily be increased to 19.6 Inches by lifting the bodywork and seat unit and mounting the rear shock in an alternative position. This, along with the ability to lower the front fork in the triple clamp and adjust the heights of the foot-peg carrier, means the rider can grow with the KTM SX-E 2.
STOPPING POWER
BRAKES
A set of radial, hydraulic 5.5 Inch disk brakes on the front and rear ensure 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 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. The ODI lock-on handgrips also feature a slim diameter to further improve control and feel through the bars.
EASY TO HANDLE
LIGHT WEIGHT
Weighing in at 59.5 Lb, the KTM SX-E 2 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. Moreso, at less than 60 Lb, the KTM SX E-2 is easily transported to and from riding locations.
CHARGED UP
MOTOR AND POWER
Providing the forward drive for the KTM SX-E 2 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.
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 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 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 a breeze, with different colors indicating which ride mode is selected and what level the battery is at.
KEEP GOING
QUICK CHANGE LITHIUM-ION BATTERY
Powering the KTM SX E-2 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.
