Plug & Play for more torque and power
The Siebenrock kits

Plug & Play for more torque and power

Nine out of ten people who mention the name “Siebenrock” have our kits for optimizing power and torque in mind. That’s why owners of a 2V boxer always have to answer one typical question at any bikers’ meeting point: "Still original or did you already mount a Siebenrock kit?" Our kits are so popular that it’s usually only a matter of time until Power Kit, Replacement Kit or Big Bore Kit make it to the personal wish list. We offer conversion kits for almost all boxer models from 1975 onwards. All our kits are designed as plug and play solutions because we prefer the pleasure of riding over the labour of conversion. You too?

Brake better
Siebenrock brake disc

Brake better

Original look, modern technology, more safety: The legendary riveted brake disc, which was not available for a long time, is celebrating its comeback. As an original Siebenrock product it works, of course, better than ever. We have reissued all common hole patterns and have them produced in highest quality at Magura. A modern chrome steel alloy, carefully heat-treated to our requirements, as well as circular grinding and partially recessed rivet heads provide more security on the road. The original look goes without saying.

Maximum comfort with original quilting

You want more long-distance comfort for your classic boxer? Invest in a new Siebenrock seat. Nowhere else our philosophy "technically improved, optically unchanged" shows as well as with the seats. Inside, a modern foam core ensures contemporary seating comfort, while the cover is indistinguishable from the original. The striking original-like quilting bears witness to our love of traditional craftsmanship. All seat parts are also available separately. It’s up to you which part of the seat you want to optimize first.

Characteristic boxer sound
Siebenrock exhaust

Characteristic boxer sound

Loud is out but the sound has to be right. That's why a 2V boxer with Siebenrock exhaust sounds exactly as its owner wants it: powerful, robust and boxer typical, but never intrusive or even annoying. The beautiful appearance of a Siebenrock SGS exhaust system pleases, the weight reduction of five kilograms convinces. For the classic boxer models we offer mufflers in the popular Hoske shape or the classical BMW look. And the original exhaust system of the legendary G/S you can also order from us.

Which exhaust do you prefer?
