speedsignal is original equipment manufacturer for radio preparation 877

As an ISO TS 16949 certified company, we are approved for direct supply to the automotive industry (TIR1). In addition to various projects from the car world, we also serve, among others, BMW motorcycles with the special equipment "877 radio preparation".

The established R@ven BlueLight system, which is used in various cars, trucks and even watercraft, was adapted for BMW to meet the special requirements of use on a motorcycle. The waterproof motorcycle control panel with "glove-friendly" operating keys and a display that is easy to read even in sunlight, blends in perfectly with the operating elements of these high-quality vehicles. Particularly noteworthy is the ergonomically optimised operation via the F1-F4 keys, e.g. as a radio button, as well as the integration of the MMC control element (turn-push button) into the operating concept of the K52.
Motorcycle Handlebar

Extended measurements guarantee OEM quality, especially in terms of reception and interference immunity. The speech quality and listening experience is excellent, both via spiral cord and via the Bluetooth functionality of BMW helmets.
We are proud that we do not only deliver single components to the assembly line, but the complete system including the antenna, all cables and brackets, as well as the on-board computer and the motorcycle control unit.
Since 2016, we have also been a nationwide BMW service partner and are the contact for this system at all branches.
