In our transmission parts category at Hornig, you will find everything you need to maintain, service or renew the transmission of your classic R80 boxer during an overhaul. The transmission is a central element of power transfer and has a decisive influence on both riding feel and reliability – the highest quality is essential here.

Basic equipment: transmission bearings & seals – durable protection for your gearbox

With the transmission bearing set PLUS, incl. cylindrical roller bearing and the classic transmission bearing set, Hornig offers robust bearing solutions for the R2V 5-speed models of the R80 series. These bearings absorb the forces inside the gearbox and ensure long-lasting, smooth operation. Equally important are our seal kits for transmissions, which prevent minor leaks and increase the service life of the gearbox.

Shift levers & shifting components – precise gear changes

For direct and accurate shifting, we provide high-quality components, including the GS foot shift lever with roller, which is particularly appreciated on off-road-oriented models such as the GS or ST. In addition, Hornig supplies various shift lever rubbers and shaft seals that improve the connection between rider and gearbox while also offering protection against dirt and moisture.

Seals, boots & housing gaskets – reliable sealing

A tight gearbox is the basis for permanently clean operation. Hornig offers rubber bellows for the drive, boots for the clutch thrust bearing and various housing gaskets that ensure neither oil escapes nor dirt penetrates. With such seals, the transmission of your classic remains dry and low-maintenance.

Other important parts around the gearbox

In addition to bearings and seals, Hornig complements the range with other practical parts: rubber bellows for the drive, clamps for secure fastening, as well as sealing rings for the neutral switch contribute to functional shifting and an all-around reliable gearbox. These components help remedy typical weak points of classic R80 gearboxes or replace them preventively.

Maintenance & replacement – keeping your gearbox in top condition

Transmission parts are subject to wear even under moderate use. Regular inspection and timely replacement of bearings, seals or shift rubbers ensure that your BMW R80 continues to shift reliably and prevents consequential damage. Hornig offers components tailored precisely to these requirements, which are durable, precisely fitting and technically reliable.
