At the heart of the DS 7 lies a robust 247 cc twin-cylinder, two-stroke engine, capable of delivering a spirited 24 horsepower at 7,500 RPM. This powerplant is not only about numbers; it's a lively, responsive engine that allows for a top speed of 140 km/h (87 mph), making it a thrilling ride for both urban commutes and weekend getaways.

What sets the Yamaha DS 7 apart from its contemporaries is its blend of classic features and reliable technology. The expanding brake systems, both front and rear, offer solid stopping power, instilling confidence in riders whether navigating city streets or tackling twisty backroads. The 12-liter fuel tank ensures that riders can enjoy extended journeys without frequent stops at the pump, making it an ideal companion for those spontaneous road trips. With its charming aesthetic and simple yet effective engineering, the DS 7 embodies the spirit of riding in a way that is both nostalgic and exciting.
