Austrian battery specialist VOLTFACTORY® has confirmed it is now manufacturing the MX50 lithium-ion battery for the 2027 KTM FREERIDE E electric motorcycle at its Bad Leonfelden production facility. The 5.5 kWh, 29 kg pack delivers an estimated two to three hours of enduro riding time and represents a 40% capacity increase over the previous generation. For procurement and engineering teams tracking the electric two-wheeler supply chain, the announcement identifies the specific supplier and manufacturing process behind the KTM FREERIDE E battery at the point of market entry.

KTM FREERIDE E battery specification and engineering approach

The MX50 operates at a nominal voltage of approximately 50 V and is rated for more than 1,000 charging cycles. VOLTFACTORY® states the 40% improvement in battery capacity has enabled a range increase of approximately 50% compared to the previous model, a gap that implies energy management gains beyond raw capacity alone. The pack weighs 29 kg, giving a useful reference point for engineers assessing the energy-to-weight positioning of the system.

For cell contacting, VOLTFACTORY® has applied a laser welding process, which the company developed at Bad Leonfelden and has described as the first of its kind for round-cell battery systems. VOLTFACTORY® states this technique maximises both performance and safety in the finished pack.

Charging via the 660 W charger delivers a full charge in eight hours and reaches 80% state of charge in under six hours. KTM’s own product documentation additionally references a 3.3 kW fast charger capable of a full charge in 1.5 hours, though this specification does not appear in VOLTFACTORY®’s production announcement for the MX50.

Supply chain implications of the FREERIDE E battery programme

The MX50 was developed jointly by KTM and VOLTFACTORY® under what both parties describe as a compressed development timeline. Arno Ebner, KTM’s Vice President of Global Procurement, cited local production as a specific sustainability factor alongside technical performance, referencing the ecological footprint reduction that domestic manufacture enables. VOLTFACTORY® produces at Bad Leonfelden in Upper Austria, the same country where KTM AG is headquartered, making this a domestically anchored supply arrangement for the Austrian OEM.

VOLTFACTORY® operates across LFP and NMC cell chemistries depending on application and covers a voltage range from 24 to 800 V at the Bad Leonfelden facility. The company also produces the FLEXCOOLER® thermal management component, though the press release does not confirm whether this is integrated into the MX50 specifically.

Production of the MX50 is already underway, running in parallel with the motorcycle’s commercial launch. The 2027 KTM FREERIDE E is available now through authorised KTM dealers.

What the MX50 specification tells engineers about the FREERIDE E platform

The 2027 FREERIDE E is the first production release of a comprehensively redesigned platform. KTM announced the model in 2024 before a production delay pushed launch to 2027, and the released specification reflects a 5.5 kWh pack supporting two to three hours of riding under endurance conditions on varying terrain.

For fleet and procurement specialists, the 1,000-plus cycle lifespan rating is the primary durability specification currently available for the MX50. VOLTFACTORY® has not published depth-of-discharge parameters or capacity retention figures alongside that cycle rating, so further technical documentation would be required before full battery management system integration assessments can be completed. The arrival of production-intent battery data marks the point at which detailed specification comparison with competing electric off-road platforms becomes possible.
