With its understated aesthetic and no-frills approach, the ETZ 251 embodies the essence of practical motorcycling, catering to those who prioritize functionality and reliability over modern complexities.

Engine Performance and Riding Characteristics
At the heart of the ETZ 251 lies a robust 243cc single-cylinder, two-stroke engine, delivering a lively 17 horsepower at 5,000 RPM. This power output, while modest in the grand scheme of motorcycles, provides an exhilarating riding experience, especially in urban settings or winding country roads. With a top speed of 113 km/h (70.2 mph), this bike is not just about leisurely cruises; it offers ample performance for zipping around town or escaping to the open road. The 5-speed gearbox complements the engine's character, allowing for smooth shifts and an engaging ride, while the air-cooling system ensures that the engine remains reliable even in warmer conditions.

Key Features and Technology
The engineering behind the ETZ 251 is as straightforward as its design. The motorcycle features a single disc brake at the front and a traditional expanding brake at the rear, providing adequate stopping power for its weight of just 146 kg (321.9 pounds). With a fuel capacity of 17 liters (4.49 gallons), riders can enjoy longer journeys without frequent stops for refueling. The bike’s 10:1 compression ratio and bore and stroke dimensions of 69.0 x 65.0 mm (2.7 x 2.6 inches) contribute to a balance of power and efficiency, making it a reliable workhorse for various riding conditions.
