The ultimate foundation for anyone who wants to give their moped—equipped with a Sachs 50/2 or 50/3 (DE) manual-shift engine—a new lease on life and smooth, clean performance: With the Signature Engine Overhaul, you’re getting an exclusive service from one of the most renowned moped shops in the scene. This isn’t a mass-produced item—it’s precision craftsmanship with character, expertise, and genuine cult appeal.
This offer is for anyone who wants to breathe new life into their moped with a Sachs 50/2 or 50/3 (DE) engine or is looking for a reliable foundation for a custom project. The engine block is intentionally overhauled without the ignition system—ideal for anyone who wants to customize their own setup.
For those who need an original ignition system, we also offer it in our shop.
At Siggnature, every engine block is completely disassembled, thoroughly cleaned, and professionally overhauled. All wear parts—such as bearings, oil seals, and even the crankshaft—are systematically replaced with new parts. All components are precisely measured, neatly assembled, and put back together as befits a professional engine overhaul. The result is a technically optimized engine that runs smoothly, performs reliably, and is ready for many trouble-free kilometers.
Even with the Sachs 50/2 and 50/3 (DE) engines, wear and tolerance issues often only become apparent upon disassembly. With this engine overhaul, you’ll create a solid, long-lasting foundation—whether for a faithful restoration or a setup with a little more punch.
Service Process: You can follow the exact process in Sigg’s video. In addition, your package includes a detailed step-by-step guide straight from the workshop to take home with you.
Note: The engine must, of course, be complete and show no damage to the casing. If defects are found during the inspection that aren’t included in the rebuild, we’ll contact you to work out a simple solution together.
An awesome custom product straight from the Siggnature workshop.
