With its unmistakable charm and robust build, the Model 31 Swift has remained a favorite among collectors and vintage aficionados, offering a nostalgic glimpse into a time when craftsmanship and character defined the motorcycle market.

At the heart of the AJS Model 31 is a powerful V2, four-stroke engine that displaces 646cc, delivering a respectable 31.4 horsepower at 6000 RPM.

Riders will appreciate the hydraulic telescopic front suspension and the twin shock Girling rear suspension, which together deliver a balanced ride, soaking up bumps and providing stability whether navigating city streets or embarking on longer journeys.

Innovation meets classic design in the AJS Model 31 Swift, with features that reflect its era while still offering practical functionality. The double cradle frame ensures rigidity and durability, while the expanding drum brakes at both the front and rear provide reliable stopping power. The kick starter adds a touch of authenticity, allowing riders to engage with their machine in a way that modern electric starters cannot replicate. With a fuel capacity of 16 liters (approximately 4.23 gallons), the Swift is well-suited for longer rides, offering a good range for exploration without frequent stops at the pump.
