SX-E 5 2021
KTM KTM SX-E 5 for Sale at Virginia KTM in Virginia, QLD | Specifications and Review Information
A NEW ERA IN OFFROAD COMPETITION
This is a high-end, adaptable, READY TO RACE electric-powered mini-crosser aimed at both beginner and competitive junior riders. With zero emissions and sound pollution, the updated for 2021 KTM SX-E 5 is at the leading-edge of competitive minicross and a viable alternative to the petrol-powered 50cc engine, bringing with it an entirely new generation of competitive racing. The KTM SX-E 5 is fitted with a compact electric motor, powered by a strong power pack, delivering almost inaudible noise emissions. It also features high-quality components that make it significantly different from the many electric minicycles available on the market. This is a fully-fledged competition motorcycle with low noise emissions, making it more accessible to younger riders for use in areas where noise emissions are restricted.
Producing a peak power of 5 kW, the permanent magnet motor features an extremely compact and slim design well suited to the smaller chassis. It is air-cooled and due to its dust and waterproof layout, the motor is wear- and maintenance-free. The integrated control unit (ECU) guarantees a direct, but very controllable power delivery.
The modern frame 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. It can be mounted in two positions for different seat heights. Together, they guarantee easy handling and precise cornering, as well as outstanding stability.
Like the full-size KTM Factory racers, the KTM SX-E 5 has super lightweight, black, anodized, aluminum rims providing the highest strength and safety. The OEM MAXXIS knobbly tires grip superbly on any surface.
The KTM SX-E 5 has a modern, fully adjustable air fork: the WP XACT, made by WP Suspension. This upside-down front fork with 35 mm tube diameter and 205 mm of travel 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.
Featuring the same level of technology offered on the full-size motocross range, the SX-E 5 is fitted with hydraulically-operated brake callipers and waved front and rear brake discs. The system ensures advanced brake feeling and stopping performance in all conditions.
The KTM SX-E 5 uses tapered NEKEN handlebars, made of a high-quality 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. The thinner diameter provides better grip for young riders while riding increasing control and drastically reducing fatigue. A 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 steps by: 1) lowering the bodywork/seat and: 2) mounting the rear shock in an alternative position, as well as lowering the front fork in the triple clamps. Additionally, by using a Suspension Lowering Kit from the accessories catalog, the suspension units can be further lowered for a minimum seat height of just 560 mm which accommodates the smallest of riders of four years old or even younger.
Modelled on the full-size motocross bikes, the KTM SX-E 5 features striking and modern graphics. Additionally, the graphics are applied using an inmold process to ensure the best durability and quality.
Using the multifunctional instrument located between steering head and seat, 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. The stored energy is 907 Wh, which is enough for more than two hours of riding for a beginner and approximately 25 min of action for the fastest riders, 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. A wrist lanyard key (connection between wrist and kill switch) 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.
