Classic Mopeds – Parts and Tuning for Ciao, Simson & Co.
You never really forget your very first moped. And anyone who has a Piaggio Ciao, Simson Schwalbe, or Kreidler Florett in their garage today knows that riding often goes hand in hand with tinkering. In our “Classic Moped” section, you’ll find replacement parts, tuning kits, and accessories for the maintenance, repair, and restoration of classic mopeds, mopeds, and mokicks. From small wear-and-tear parts to larger engine projects—the key is that the part fits your specific model.
From the Piaggio Ciao to the Simson S51
Among the best-known Italian classics are the Piaggio Ciao, Si, Bravo, Boxer, and Grillo. From Suhl come the Simson Schwalbe (KR51/1 and KR51/2), the Vogel series with the Star, Sperber, and Habicht, as well as the S50, S51, SR50, and SR80. Also included are West German mopeds from Kreidler, Zündapp, and Hercules —such as the Florett and Prima—the Austrian Puch Maxi, and other European two-stroke models like the Peugeot 103 or MBK 51. The selection varies depending on the brand and model: While there are numerous engine and tuning parts available for popular series, the selection for rarer vehicles may be more limited.
Maintenance, Engine Overhaul, and the Right Setup
Whether your moped is hard to start, is drawing in air, or needs to be brought back to life after years of inactivity: The work often begins with engine and wear parts. These include gaskets, bearings, crankshafts, cylinders and carburetors , including jets. For Piaggio mopeds, you’ll also find parts for belt drives and variators. Brands such as Dell'Orto, Malossi, Polini, Pinasco, and Schmitt offer solutions ranging from stock-like replacements to high-performance engine builds, depending on the vehicle.
The accessories have to be just right, too: In the electrical system section, you’ll find ignition and lighting components for various vehicle electrical systems; under Wheels , you’ll find matching tires, inner tubes, and brake parts. Frame and attachment parts as well as accessories help with rebuilding and equipping your bike for everyday use.
For the workbench and your next ride
At Scooter Center, moped know-how isn’t just in the catalog. In the Ciao tuning and setup guides covers carburetors, pulleys, and the tuning of individual components; our reports on moped tours show what really matters on the road. We also offer selected parts from bgm PRO and Moto Nostra are available for Piaggio mopeds—such as brake components or practical tool bags. The vehicle and product compatibility guide helps you determine which version is truly compatible.
Understanding Classic Mopeds—Models and Parts Selection
Do Ciao parts also fit the Si, Bravo, and Boxer? In some cases. The Piaggio model series share technical fundamentals but differ in year of manufacture, engine, and drivetrain. Be sure to check whether the moped has a Mono or Variomatik transmission, and for cylinders, check the piston pin diameter (for example, 10 or 12 mm). A similar engine doesn’t automatically mean that every part is interchangeable.
Which parts fit my Simson? The S50, S51, Schwalbe KR51/1, and KR51/2 do not all use the same engine generation across the board. The engine type is particularly crucial when it comes to the cylinder, clutch, and ignition. Before converting to a 12-V electronic ignition system, you should also check the compatibility of the existing system, the regulator, the lighting, and the specific conversion kit. For select Simson models, there are, among other things,
Schmitt engine components.
And what about Puch, Kreidler, Zündapp, and Hercules? Wear-and-tear parts and tuning parts are also available for Puch Maxi, Kreidler Florett, Zündapp, and Hercules models, as well as Sachs engines, depending on the specific version. For these vehicles, the engine type, displacement, year of manufacture, and dimensions are often more indicative than the brand name alone. For other classic two-stroke models, such as the Peugeot 103 or MBK 51, it’s also worth checking the specific model details.
What makes for a well-balanced two-stroke setup? Cylinder,
carburetor, air filter, exhaust, and gear ratio must all be compatible. A larger jet or a different V-belt isn’t the right solution for every engine. Changes to power or top speed can affect the vehicle’s operating permit. Always check the approvals and intended use on the specific product page.
How do I find the right replacement part? Start by selecting the vehicle, then compare the nameplate, engine identification number, and the information on the product page. For brakes and wheels, dimensions such as diameter, width, and rim size are also important; for electrical systems, voltage and design type matter. Especially after previous modifications, checking the part actually installed is often more important than the original model designation.
