01. Drivetrain

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 waterproof which makes it wear and maintenance-free, while the integrated control unit (ECU) guarantees a direct, but very controllable power delivery.

02. Chassis

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 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.
