What more cubic capacity brings
Original drives. Tuning drives more freely.
A tuning cylinder gets more out of the engine without making it complicated.
Better response behaviour, more torque, noticeably more pull.
No witchcraft. Just clean technology.
Ingenious cylinders
swiing® ingenious cylinders are not loud, they are built right.
Clean channels, harmonious timing, honest performance - with a high-quality finish.
Made for mechanics who want to ride.
Lay your cards on the table

Before the conversion. After the conversion. Directly comparable.

In good hands
Engines for Sachs, Puch and Piaggio are completely dismantled, checked and neatly rebuilt here. Wheels are spoked, conversions are planned and realised, restorations are carried out with patience. Not according to a scheme, but according to condition and requirements.
Why does this make sense? Because experience makes the difference. A professionally overhauled engine runs more smoothly, lasts longer and doesn't make you wonder. You save yourself detours, reworking and half solutions. Your motorbike won't come back faster, but better. And that's what it's all about.
Remember setups
Ideas come quickly. Parts are forgotten just as quickly.
With the Kultklub wish lists, you can collect setups, memorise conversions and plan your next project. All in one place.
