Collection: Transmitters and sensors for Harley-Davidson, Indian and metric custom motorcycles

The engine "speaks" continuously – but in a language only the sensors understand. RPM, temperature, oxygen content, speed, lean angle: every moment, it's decided how the engine control unit should react, how much fuel to inject, when to ignite, and when the safety system should intervene. If a sensor gives faulty readings or stops working altogether, the engine will eventually feel it – uneven idling, a fault code, or simply that uncertain feeling that something isn't right. Our range includes RPM and position sensors, which are essential for precise ignition timing and fuel injection, as well as temperature sensors that measure engine and air temperature to help set the optimal air-fuel mixture. Oxygen sensors are available, contributing to efficient combustion by monitoring exhaust gas composition; speed sensors for accurate dashboard display; and oil pressure and level sensors that continuously monitor the engine's lubrication system. Our range also includes lean angle sensors – a safety feature that automatically shuts off the engine in case of a rollover – as well as lambda and mass air flow sensors for precise air-fuel ratios, especially in fuel injection systems. Quality sensors provide accurate, stable signals, ensuring that the engine control unit always works with real data – which means smoother running, better fuel economy, and longer engine life. Whether you're looking for a replacement due to a fault code or a complete diagnostic overhaul, you'll find the right sensor for your engine with us.
