The KTM SX-E 5 is an all-electric mini-crosser aimed at both beginner and competitive junior riders. With zero emissions and minimal sound pollution, it takes its place at the leading edge of competitive mini-cross, and provides a real-world READY TO RACE alternative to the petrol-powered 50 cc engine. Featuring high-quality components that make it significantly different from the many electric mini-cycles available on the market, the KTM SX-E 5 is a fully-fledged competition motorcycle, making it more accessible to younger riders for use in areas where noise emissions are restricted.
This fully electric, battery-powered air-cooled permanent magnet motor features an extremely compact and slim design that perfectly matches the KTM SX-E 5's smaller chassis. It's 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.
The KTM SX-E 5 has a modern frame design that is made of lightweight, high-strength Chromoly steel profiles and combines maximum longitudinal stiffness with optimum torsional rigidity. The subframe is made of lightweight, fiber-glass reinforced extruded plastic elements, which can be mounted in two positions for different seat heights. This means that the KTM SX-E 5 can 'grow' with your young racer.
Like the full-size KTM Factory racers, the 2023 KTM SX-E 5 is fitted with lightweight, black anodized, aluminum rims which provide the highest strength and durability for any eventuality. These are wrapped in new MAXXIS MX-ST tires, to provide unmatched traction on any surface.
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.
The high-quality WP XACT shock absorber is linked directly to the new 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 185 mm of rear-wheel travel.
The KTM SX-E 5 is fitted with front and rear hydraulic brakes by FORMULA, combined with lightweight wave discs that are easy to control even for the youngest riders, helping to build thier confidence, and taching them correct brake control.
The KTM SX-E 5 uses high-quality tapered NEKEN handlebars, made of aluminum alloy ensuring top stability and safety. Its diameter tapers from 28 mm in the central area, to 22 mm in the bends, to 18 mm in the handhold area. This allows for a thinner lock-on ODI grip to be mounted on the left side while the right side features a newly developed 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.
The seat height on the KTM SX-E 5 can be adjusted to multiple levels. The standard model comes with a seat height of 665 mm, which can easily be reduced to 615 mm 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. Additionally, by using a Suspension Lowering Kit from the KTM PowerParts catalog, the suspension can be further lowered for a minimum seat height of only 560 mm which accommodates the smallest riders of four years old or even younger.
The 2023 KTM SX-E 5 features the latest in-mold graphics, with a bold orange and blue design that perfectly sets off the factory-look orange frame, orange seat and and race-sharpened bodywork.
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.
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 25 min full-throttle racing, depending on conditions and terrain. The integrated battery management system (BMS) ensures the safety and longevity of the battery pack.
The KTM SX-E 5 is fitted with 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. 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.
