About Amerschläger P4
Amerschläger P4 has been developing and manufacturing dynamometers for two-wheelers for over 40 years, made in Germany. The product portfolio includes the P4 SC100 and SC100 EC dynamometers (two-wheelers up to 100 hp, optionally with eddy current brake for complex load simulations), the proven P4 Dynamic for classic full-throttle power curves, and the P4 Simulator with eddy current brake, extended measuring channels and automated resistance simulation. The range is complemented by measuring and data acquisition devices such as the P4 Lambdatool for Lambda/AFR measurements and the Redbox v4 OBD for grid measurements via CAN bus and OBD. The dynamometers are modular in design, plug-and-play capable and can be extended via software updates and the Mission Control app. Customers include motorcycle tuners, workshops, racing teams such as the IDM and EURO MOTO, as well as training institutions such as the Straubing vocational school. In addition, the company offers a mobile trailer-mounted dynamometer as a rental and event service, video training courses and an online shop.
