SX-E 3

The ideal entry point for what could be a lifetime of motorcycling. The KTM SX-E 3 is the cutting-edge all-electric mini-crosser aimed at thrill-seeking juniors. A fresh generation of machinery that will entice the next generation of riders. The KTM SX-E 3 slides into the range below the more powerful KTM SX-E 5 but with an ultra user-friendly package, high-quality components and that READY TO RACE styling. A manageable power output, generous battery capacity, and adjustable ergonomics make it the perfect choice for youngsters graduating out of balance bikes and into their first proper meters as a 'biker'. Quiet, easy, enjoyable. Get them moving.

01. DRIVETRAIN

MOTOR

This fully electric, battery-powered air-cooled permanent magnet motor produces a healthy 3.8 kW, featuring an extremely compact and slim design that perfectly matches the KTM SX-E 3'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.

02. CHASSIS

FRAME

The KTM SX-E 3 has a modern frame design that is made of lightweight, high-strength chromium-molybdenum steel profiles and combines maximum longitudinal stiffness with optimum torsional rigidity. The modification on the latest model provides more robustness, handling and a tougher rear shock mounting point. The subframe continues to be made of lightweight, fiber-glass reinforced plastic, which can be mounted in several positions for different seat heights.

WHEELS

The KTM SX-E 3 is again fitted with 10" wheels front and rear, and just like the bigger machines, these lightweight, black anodized, aluminum rims provide the highest strength and durability. These are wrapped in MAXXIS MX-ST tires, to provide unmatched traction on any surface.

FRONT SUSPENSION

The KTM SX-E 3 is fitted with non-adjustable upside-down WP XACT 35mm forks. Class-leading in their own right, the forks provide exceptional damping and comfort characteristics allowing the rider to build confidence and push their limit, while the 144 mm of wheel travel means the limit is a far way off indeed.

REAR SUSPENSION

The WP monoshock absorber is linked directly to the swingarm and is perfectly matched to the front suspension, providing excellent damping performance. The shock absorber also allows for 129 mm of rear wheel travel - preload adjustable - providing advanced comfort on all terrains.

BRAKES

Featuring the same level of technology offered on the full-size motocross range, the KTM SX-E 3 is fitted with hydraulically operated brake calipers and wavy discs front and rear. The hand-operated system ensures advanced brake feeling and stopping performance in all conditions while allowing young riders a more natural way of getting to grips with the brakes.

03. ERGONOMICS & COMFORT

HANDLEBAR

The KTM SX-E 3 uses high-quality tapered NEKEN handlebars, made of aluminum alloy ensuring top stability and safety. With 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 3 can be adjusted to multiple levels. The window of change goes from height of 634 mm to 682 mm which can easily be reduced in two easy steps by lowering the bodywork and seat and mounting the shock absorber in an alternative position. The front fork can also be lowered in the triple clamps.

04. SOFTWARE & ELECTRONICS

BATTERY

The KTM SX-E 3 is fitted with 60 modern lithium-ion cells in a robust die-cast aluminum housing mounted just above the motor, storing 648 Wh of energy. This allows more than two hours of riding for a beginner, with even the fastest young riders only able to deplete the battery in around 30 minutes. And should you want more time between charges, the battery can be upgraded to the SX-E 5 battery with 907 Wh, ensuring up to 25% more riding.

CHARGER

The charger supplying up to 350W can be connected to any 110 or 230 volt socket and plugs directly into the battery back for easy charging.

• Charging time 0 - 80% = 100 minutes

• Charging time 0 - 100% = 140 minutes

RIDE MODES

A multifunctional instrument display is located between the steering head and seat. Here, the user can select between the 6 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 3 is fitted with a roll-over 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.
