About Velocette Mac 1937

Step back in time to the golden age of motorcycling with the 1937 Velocette Mac, a charming blend of classic design and innovative engineering. Positioned as a versatile all-rounder, the Mac was crafted for those who craved both the thrill of the open road and the practicality of everyday use. Its sleek lines and robust build reflect the artistry of pre-war British motorcycle manufacturing, making it a sought-after model among collectors and vintage enthusiasts alike. With a history steeped in racing pedigree, the Velocette Mac embodies an era when motorcycles were not just machines, but expressions of freedom and style.

At the heart of the Mac lies a spirited 349cc twin, four-stroke engine that produces a respectable 18 horsepower at 5,500 RPM. With a compression ratio of 6.8:1 and a bore and stroke of 68.0 x 96.0 mm, this powerplant delivers a top speed of 120.7 km/h (75.0 mph), making it an exhilarating ride for its time. The machine’s 4-speed gearbox, paired with a wet multiplate clutch and chain final drive, ensures smooth gear transitions and a responsive throttle. Riders will appreciate the Mac’s lively acceleration and spirited handling, thanks to its lightweight frame of just 161 kg (354.9 lbs) and hydraulic telescopic front forks that deliver a comfortable ride even on less-than-ideal roads.

The Velocette Mac is not only a joy to ride but also features a number of advanced technologies for its era. The air-cooled engine is fed by a carburettor and ignited by a reliable magneto, ensuring a seamless performance whether you’re cruising through town or embarking on a longer journey. The single cradle frame provides stability, while the expanding drum brakes—178 mm at the front and 152 mm at the rear—offer adequate stopping power for a bike of this vintage. With a seat height of 700 mm, it accommodates riders of various sizes, making it an accessible choice for those new to motorcycling or seasoned riders looking for a classic experience.

Pros:

  1. Classic Styling: The Velocette Mac's retro design and craftsmanship make it a standout piece for collectors and enthusiasts.
  2. Smooth Handling: The combination of a lightweight frame and hydraulic front suspension provides a nimble and enjoyable riding experience.
  3. Dependable Performance: With its robust engine and straightforward mechanics, the Mac is easy to maintain and reliable for weekend rides.

Cons:

  1. Limited Power: While adequate for leisurely cruising, the 18 HP engine may not satisfy those seeking high-performance thrills.
  2. Drum Brakes: The expanding drum brake system, while effective for its time, may not offer the stopping power that modern riders expect.
  3. Kick Start Only: The absence of an electric starter may be a drawback for some, requiring a bit of effort to get the engine running.

In sum, the 1937 Velocette Mac is more than just a motorcycle; it’s a piece of history that invites riders to experience the golden age of motorcycling. Whether navigating city streets or exploring winding country roads, the Mac promises an engaging ride steeped in tradition and charm.
