Engines overhaul and tuning

But it's not just BMW engines that we specialise in. We also work on older Japanese, Italian or English engines to the same extent. Whether cylinder head revision or tuning, drilling and honing or a complete rebuild. You've come to the right place.

Our advice
Safer on the road with the first BMW 2-valve engine with ABS – unique worldwide!We are the first motorcycle manufacturer in the world to equip the classic BMW two-valve model with a modern ABS system – and it has been approved by TÜV! Following intensive test rides and extensive brake tests on special tracks, we have adapted a system that takes the riding safety of these legendary machines to a new level. The ABS, which was developed specifically for our bikes, is available in two versions:
• Dual-circuit system for Twinshock models – front and rear wheels are controlled separately
• Single-circuit system for front drum brakes – ideal for models with single front disc
The ABS significantly minimizes the risk of falling, especially on the front wheel, and ensures maximum control in critical riding situations. The components and software are state-of-the-art and have been specially programmed and adapted for our vehicles. The complete conversion with the single-circuit system is available from $3,869 (plus TÜV registration).

We can also do others.....
At SE, everything revolves around motorcycle conversions. Exclusive cafe racers, scramblers, roadsters and bobbers are created in our workshop. The focus is on BMW 2-valve models, but other makes and models are not neglected either.
We can realize completely individual conversions according to your ideas and based on your desired motorcycle. We are a certified company with our own engineering department and work closely with the TÜV. This means that we can also legally put customized frame and chassis modifications on the road.
