KTM’s electric off-road youth motocross bikes, the SX-E 3 and SX-E 5, continue to dominate the 2024 market without any significant alterations. These bikes, renowned for their air-cooled 48-volt BLDC motor, sturdy double-cradle chromoly steel frame, and 160mm disc brakes on both wheels, have set a high bar in the industry.
Despite having many common features, the SX-E 3 and SX-E 5 differ notably in terms of battery capacities. The SX-E 3 comes equipped with a 648Wh battery, while the larger SX-E 5 boasts a 907Wh battery. In addition to the increased battery capacity, the SX-E 5 also offers enhanced suspension travel and a larger front wheel. Both models use the same Maxxis MX-ST tires, with the SX-E 3 weighing 86 pounds and the SX-E 5 slightly heavier at 90 pounds.
Retailing at $5,099, the SX-E 3 represents KTM’s smallest electric dirt bike, while the SX-E 5 is incorporated into KTM’s Junior Supercross program at select rounds of the AMA Supercross series.
These models incorporate advanced safety features such as a tip-over sensor that instantly halts the motor during a fall, and a wrist lanyard that cuts off power to the motor if it detaches from the handlebar socket. Moreover, the SX-E 3 offers three power modes, allowing a customized performance for young riders honing their off-road motorcycle skills.
Since its launch in 2012, KTM’s Freeride E-XC has carved a niche for itself in the market. Despite receiving only limited updates since 2018, it continues to impress with its performance. The E-XC, weighing in at 245 pounds, handles like a hybrid trials/enduro bike, feeling light and nimble despite its weight. It’s ideally suited for rocky terrains due to its impressive 340 mm ground clearance.
The E-XC’s battery life varies based on rider skill level, speed, and terrain. While one rider might enjoy a full day of battery life, others may find the battery depleting more quickly. Soft dirt proves challenging for electric bikes as it consumes power rapidly. A beginner rider might enjoy approximately three hours of trail riding on a full charge, whereas a professional rider on a racetrack may only get around 35 minutes.
Looking ahead, KTM has ambitious plans to broaden its range of electric bikes. It intends to introduce over 20 electric off-road motorcycles across all brands, catering to all skill levels, from beginners to competition-level models.
