The third model of the Freeride E family is KTM’s first street-legal electric bike.
After the Motocross and Enduro versions, the Supermoto is a battery-powered playbike
that can also double as one of the coolest commuters out there.
Officially unveiled at last year’s Intermot, the E-SM joins the E-SX and E-XC in the electric
branch of the Freeride series. Unlike its siblings it is road-legal and, most
importantly, accessible to holders of the A1 European driving license.
Restricted to 125 cc or 11 kW (15 hp) this license class is the compulsory
gateway to motorcycling for young Europeans.
At the heart of KTM’s new supermoto lives a liquid-cooled brushless, permanent-magnet,
synchronous motor which can produce a continuous output of 15 hp, with short
bursts at its peak power of 22 hp. Maximum torque reaches up to 42 Nm.
Power is conveyed to the rear wheel through a fixed gear transmission, eliminating the
need for a clutch and allowing the allocation of the left hand lever on the
handlebars to the rear brake – a scooter-like configuration. The motor’s
management offers three different ride modes, each with a different power
delivery: economy, standard and advanced. The rider can select the mode of
choice at the touch of a button on a panel located between the saddle and the
The power source for the motor is a 300V li-ion battery developed in cooperation with
Samsung, weighing 28 kg (62 lb) and producing 2.6 kWh. It requires 80 minutes for a
full charge or just 50 to reach 80 percent. At full capacity it can power the
bike for a maximum of one hour, depending on output level and riding style. Designed
to be easily removable, once exhausted it can be swiftly replaced with a
Just like every other member of the Freeride family, the E-SM is built around a composite
frame consisting of two aluminum central braces, connecting a steel tubular structure
that uses the motor as a stressed member with a heavy duty polyamide fiber
subframe. Suspension is supplied by KTM’s long-term partner WP, with a 43-mm
upside-down fork and a PDS shock absorber. The typical supermoto package
includes 17-inch Giant wheels with sticky Pirelli Diablo Rosso tires. Braking
duties are tended by a pair of radially-mounted Formula brake calipers with
four pistons at the front and two at the rear.
Weighing just 108 kg (238 lb) in “Ready to Race” trim, the E-SM can be a short-distance
commuter or an incredible playbike – as the talented French stunt rider Julien
Dupont demonstrates in KTM’s official video presentation below.
With an average price tag north of €11,000 (about £10,000GBP) in European markets, it can
also prove to be a rather exclusive ride.
