Ventus RYUGA Motor (52KW & 81KW)

81Kw=110 HP

52Kw= 71Hp

Stark Varg=80Hp

To reach maximum KW requires an upgraded battery and controller for most bikes.

The Ventus Ryuga 52 kW Hairpin Motor serves as a lightweight, drop-in racing upgrade designed to unlock astronomical performance for lightweight e-moto platforms. Swapping out traditional round wires for cutting-edge flat copper bar "Hairpin" winding technology, this engineering marvel dramatically increases copper density to achieve a maximum efficiency of ≥95%. Weighing a compact 10.4 kg, it unleashes up to 52.5 kW of peak power (equivalent to roughly 70 HP) and 91 N·m of instant torque. It handles a blistering 14,000 RPM maximum speed with near-zero energy loss. Built with a reinforced steel-alloy shaft, precise natural air cooling, and an IP67 waterproof rating, it eliminates thermal sag. This system delivers linear, predictable throttle response even under crushing competitive loads

The Ventus Ryuga 81 kW Hairpin Motor is an absolute high-voltage monster engineered as a plug-and-play powerhouse exclusively for heavy-hitting platforms. Utilizing the same highly efficient flat wire hairpin architecture, this 12.5 kg unit handles a staggering 1400 A of maximum phase current and features a massive insulation safety cutoff threshold at 250°C. When driven on a 72V configuration, it unleashes a brutal 60.3 kW of power, but when paired with a 96V battery setup, it screams to life with 81 kW of peak power and 114 N·m of raw torque. This explosive setup pushes a max stable speed of 14,000 RPM, achieving tested track speeds up to 195 km/h. Wrapped in a rugged, precision-machined CNC housing with IP67 waterproofing and an ABZP position encoder, it delivers crisp, bulletproof acceleration built to dominate competition tracks.
