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.
2025 KTM SX-E5 Totalmotorcycle.com Features and Benefits
Motor
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 motor continues to boast an extremely compact and slim design that perfectly matches the KTM SX-E 5’s minimal chassis. It is also dust and water proof which makes it wear and maintenance-free, while the integrated control unit (ECU) guarantees a direct, but very controllable power delivery.
Frame
The KTM SX-E 5 frame is forged from lightweight, high-strength Chromoly steel profiles and combines maximum longitudinal stiffness with optimum torsional rigidity. The modification provides more robustness, handling and a tougher rear shock mounting point. The subframe is made of lightweight, fiberglass reinforced plastic, which can be mounted in diffrent positions for different seat heights. This means that the KTM SX-E 5 can ‘grow’ with your young racer.
Wheels
KTM SX-E 5 is fitted with 12″ and 10″ lightweight, black anodized, aluminum rims which provide the highest strength and durability for any eventuality. These are wrapped in MAXXIS MX-ST tires, to provide unmatched traction on any surface.
Front suspension
The KTM SX-E 5 boasts a fully adjustable, upside-down WP XACT air fork with a 35 mm tube diameter and 205 mm of travel. This ensures outstanding comfort, damping characteristics, and directional stability. Another main benefit for junior riders is that the air spring fitted in the left fork leg can be adjusted perfectly to the rider’s weight using a simple air pump.
Rear suspension
The premium WP XACT shock absorber is linked directly to the cast swingarm, providing excellent damping performance. It is fully adjustable, meaning you can set the damping perfectly to suit the rider’s preference and track conditions. The shock absorber allows for 193 mm of rear-wheel travel.
Brakes
The KTM SX-E 5 is fitted with front and rear hydraulic brakes, combined with lightweight wave discs that are easy to control even for the youngest riders; helping to build their confidence, and teaching them correct brake control.
Handlebar
The KTM SX-E 5 again uses high-quality tapered NEKEN handlebars. This allows for a lock-on ODI grip to be mounted on the left side while the right side features a throttle assembly with a vulcanized ODI grip, specifically developed for the electronic drive. An additional crash pad on the handlebar brace protects the rider from rough contact.
Seat height
The seat height on the KTM SX-E 5 can be adjusted to multiple levels. The standard model comes with a seat height variance window of 24.9-26.8 in (634-682 mm) and can be changed in two easy steps by lowering the bodywork and seat and mounting the rear shock in an alternative position. The front fork can also be lowered in the triple clamps.
Ride modes
A multifunctional instrument display is located between the steering head and seat. Here, the user can select between the six different ride modes. Each mode offers different power characteristics suited for pure beginners all the way up to experienced racers. The instrument also displays the remaining charge of the battery.
Safety
The KTM SX-E 5 is fitted with a rollover sensor that cuts off the power in the event of a fall. For further safety measures, the ride modes can be locked and saved with a dongle located below the seat. This prevents younger, less experienced riders from changing to more powerful ride modes on their own.
Battery
The KTM SX-E 5 is fitted with 84 modern lithium-ion cells in a robust die-cast aluminum casing that is mounted just above the electric motor. This means the stored energy is 907 Wh, which is enough for more than two hours of riding for a beginner and approximately 30 min full-throttle racing, depending on conditions and terrain. The integrated battery management system (BMS) ensures the safety and longevity of the battery pack. Charging time has been reduced, with 0-80% capacity achievable in 45 minutes while 0-100% is possible in just 70 minutes.
