1956 Horex Regina 350 Technical Analysis & Specification Breakdown
Positioned in Horex's allround motorcycle lineup, the 1956 Horex Regina 350 utilizes a 342 cc (20.9 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 19 HP (13.9 kW) at 6,250 rpm. With a specific output of 55.6 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Regina 350 measures 145 kg (320 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.63 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
