The foundational step has been polished, and the new 2025 KTM SX-E 5 mini cross motorcycle represents a benchmark in the industry for the commitment to quality. The KTM SX-E 5 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 5:
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 water proof 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, it’s a high quality and real-world READY TO RACE alternative to the petrol-powered 50 cc engine. A multifunctional instrument display shows the state and charge level of the battery, in addition to 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-E 5 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 24.9-26.8 inches (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. 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 WP XACT air fork with a 35 mm tube diameter 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 compression) and linked directly to the cast swingarm, providing excellent damping performance with 193 mm of travel.
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. An advanced battery management system 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. Safety features? Of course. A rollover sensor 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 the 2025 KTM SX-E 5. The 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 NEKKEN handlebars taper from 28 mm in the center to 22 mm in the bend to 18 mm in the grip, enabling the use of thinner lock-on ODI grips, engineered especially for electric drive. Also, on a theme of strength, the bike has light, black anodized, aluminum rims (12” front and 10” rear) with MAXXIS MX-ST tires for superb all-round traction across diverse terrain. Top-spec wheels are common components through the full-size KTM SX range. Another area of shared engineering is the hydraulic brake calipers and waved discs front and rear, supplied by braking experts Brembo. The design of the KTM SX-E 5 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.
The new 2025 KTM SX-E 5 will be rolling off the Austria production line and available at authorized KTM dealers from November onward. For more information, visit ktm.com.
