Simson Schwalbe KR 51/1 Classic Motorbikes: Prices & Market Values
The market value of Simson Schwalbe KR 51/1 motorcycles is primarily determined by technical condition, originality, and mileage, as well as rarity, history, and documentation. A well-maintained, largely original vehicle with low, verifiable mileage and a complete history including expert reports and documentation generally achieves significantly higher prices than a comparable vehicle with deferred maintenance, extensive modifications, or an unclear provenance.
Simson Schwalbe KR 51/1: Market Prices & Value Trends
Based on Classic Trader marketplace sales data from June 2021 to April 2025, the Simson Schwalbe KR 51/1 market shows a clear firming trend, with most advertised values now sitting higher than early-2021 examples. The bulk of recent German and wider European adverts cluster around roughly £1,500 to £2,700, suggesting this is the most realistic price corridor for typical roadworthy bikes from the late 1960s through to 1980. Cheaper entries appear around £1,000–£1,200, but these are less common and should be treated as condition-dependent. At the upper end, occasional higher figures (up to about £4,300) show that top-condition, restored, or particularly desirable year/spec bikes can command a premium, yet these are not representative of the mainstream market. For buyers, this means the KR 51/1 is no longer a “budget classic”: steady demand for iconic East German design, improving parts support, and the appeal of simple, usable 3–4 hp mopeds are helping values stabilise at a higher level rather than falling.
History of the Simson Schwalbe KR 51/1
Manufactured in the former German Democratic Republic, the Simson Schwalbe KR 51/1 established itself as a staple of everyday mobility in East Germany. Simson, with its rich history in two-wheeler construction, designed the Schwalbe KR 51/1 from the late 1960s onwards, focusing on durability and straightforward maintenance. Throughout the years, the model became synonymous with reliable commuting in urban and rural landscapes, often passed down through multiple generations.
Model history
The KR 51/1 followed in the tracks of Simson's successful SR and KR series, building on their technical concepts. Its immediate predecessor, the Schwalbe KR 50, laid the groundwork, while later models like the KR 51/2 introduced refinements in engine and suspension. The KR 51/1 stands out as a snapshot of its era, collecting technical progress up to that time and serving as a bridge to subsequent advances made in later Simson mopeds.
Special features of the Simson Schwalbe KR 51/1
A standout of DDR engineering, the KR 51/1 features a carburettor-fed engine and mechanical simplicity—allowing easy maintenance and repairs even without advanced workshop tools. Unique in design with its prominent leg shield fairing and classic lines, the model often survives with original Pneumant tyres and factory paint. Equipped with basic amenities like a functioning speedometer, fuel tap, and reliable brakes, every journey feels authentic to its roots.
Technical data
Special Editions and Collectible Models
Simson produced various colourways and minor equipment variations for the Schwalbe KR 51/1, often tailored to specific years or export needs. Models featuring original Pneumant tyres or preserved factory finish are especially sought after due to the authenticity they represent. No limited edition variants are noted, clarifying the focus on function over exclusivity.
Weak spots and common issues
The KR 51/1, while robust, requires periodic checks of the carburettor, brake adjustment, and fuel tap operation. Age-related issues can include fuel tank corrosion, oil leaks, and electrical contact wear. Original DDR tyres, while a collector’s delight, may display cracking with age and should be inspected carefully before use. Documentation is valuable—original papers confirm the bike’s provenance and ease registration.
Engine, performance and handling
The heart of the KR 51/1 lies in its two-stroke engine, delivering dependable performance on both urban and country routes. Its straightforward transmission ensures predictable gear changes, and the frame geometry prioritises stability over outright speed. Handling is direct, with the full-length leg shield providing surprising weather protection for a machine of this class. All Schwalbe KR 51/1 variants share similar technical architecture, with popularity influenced mostly by originality of parts such as tyres, paintwork, and period-correct accessories rather than unique performance differences.
Interior, comfort, exterior and design
Design influences for the KR 51/1 draw directly from the utilitarian needs of DDR citizens. The shell frames the rider, with a spacious saddle and well-positioned controls for practicality on daily commutes. Simple materials dominate—sheet metal, vinyl, and DDR-era plastics—while select models boast distinctive colour schemes. Original accessories such as the full tool kit, specific handlebar grips, and working speedometers are prized by collectors for their historical accuracy.
Other unique features
The Schwalbe KR 51/1 is one of the few mopeds legally permitted in several countries to be operated under vintage vehicle regulations. This status sometimes allows owners easier access to low-emission zones. Its straightforward mechanics also make it a classic candidate for restoration projects by both experienced hobbyists and beginners.
Summary
The Simson Schwalbe KR 51/1 is firmly embedded in German moped history, especially noted for its practical design, technical resilience, and strong presence both in the current marketplace and among riding communities. With complete documentation, original features, and ease of restoration, it remains a compelling option for anyone seeking a slice of DDR mobility.
