About Lem R3 1936

Introducing the 1936 Lem R3 motorcycle, a remarkable embodiment of early 20th-century engineering that stands as a testament to the era's innovative spirit. Positioned as an allround motorcycle, the Lem R3 was crafted to cater to a diverse audience of riders seeking both utility and adventure. With its striking aesthetic that showcases vintage charm, this motorcycle captures the hearts of collectors and enthusiasts who appreciate the blend of classic design and reliable performance. The R3 serves as a nostalgic nod to simpler times, while still delivering a ride that resonates with the thrill-seeking nature of motorcycling.

At the heart of the Lem R3 lies a robust 305cc single-cylinder, four-stroke engine that churns out 11.01 horsepower at 4200 RPM. This power, while modest by today's standards, is perfectly sufficient for navigating the open roads of the 1930s. The motorcycle reaches a top speed of 100 km/h (62.1 mph), allowing for spirited rides without compromising on safety. Coupled with a compression ratio of 6.1:1 and an efficient air-cooled design, the R3 boasts impressive fuel economy, consuming just 3.00 litres per 100 km (78.41 mpg). The shaft drive system ensures smooth power delivery, while the cable-operated dry single-plate clutch provides a tactile feel that riders will appreciate, making each ride a connection to the machine.

The Lem R3 also showcases a number of key features and technologies that enhance both performance and rider comfort. Its single cradle frame offers a balance of strength and agility, allowing riders to maneuver confidently. The combination of drum brakes—180 mm in diameter both front and rear—ensures dependable stopping power, while the cartridge front suspension absorbs road imperfections, providing a smoother ride. Not to be overlooked, the motorcycle includes a kick starter, a nostalgic feature that harkens back to the era of hands-on mechanical engagement. With a weight of 149 kg (328.5 lbs) and compact dimensions, the R3 is easily manageable for riders of varying experience levels.

Pros:

  1. Classic Design: The Lem R3's vintage aesthetic appeals to collectors and enthusiasts alike, making it a standout piece in any motorcycle collection.
  2. Impressive Fuel Efficiency: With a consumption rate of 78.41 mpg, the R3 offers outstanding efficiency, making it a cost-effective option for long-distance rides.
  3. Smooth Power Delivery: The shaft drive system provides seamless acceleration and reduces maintenance, allowing riders to focus on the joy of the ride.

Cons:

  1. Limited Power Output: With only 11.01 HP, the R3 may struggle to keep pace with modern traffic or more powerful motorcycles.
  2. Basic Suspension Setup: The rigid rear suspension can lead to a less comfortable ride on bumpy roads compared to more advanced suspension systems available today.
  3. Kickstarter Only: The absence of an electric starter may deter some riders who prefer the convenience of modern starting systems, especially in challenging situations.

In summary, the 1936 Lem R3 motorcycle is a delightful blend of history and mechanical ingenuity, inviting riders to immerse themselves in the nostalgia of early motorcycling while enjoying a ride that is both practical and enjoyable.
