Key specifications
Overview
Introducing the 2021 Fosti F31, a versatile allround motorcycle poised to capture the hearts of both novice riders and seasoned enthusiasts alike. With its striking green and black color scheme, the F31 stands out in the crowded motorcycle market, offering a blend of stylish design and practical functionality. This Chinese-made motorcycle is crafted for those who seek a reliable companion for daily commuting, weekend adventures, or everything in between. Its lightweight frame and approachable ergonomics make it an ideal choice for urban riding, while also providing the thrill that motorcycle lovers crave. At the heart of the F31 lies a spirited 149cc engine, delivering 12.1 horsepower at 9,000 RPM and 9.0 Nm of torque at 7,500 RPM. This efficient powertrain ensures that the motorcycle is nimble enough to navigate tight city streets while still offering a top speed of 90 km/h (55.9 mph) for those open-road jaunts. The carbureted fuel system contributes to the bike's impressive fuel consumption rate of just 2.20 liters per 100 km (or an astounding 106.92 mpg), making it a smart choice for budget-conscious riders. The combination of a lightweight chassis—tipping the scales at only 110 kg (242.5 pounds)—and responsive handling ensures a confident ride whether you're dodging traffic or cruising along scenic highways. The F31 also boasts a well-thought-out chassis and suspension setup, featuring a telescopic front fork and dual shock absorbers in the rear. This configuration not only provides excellent stability but also enhances comfort for the rider, allowing for smooth handling over various terrains. The single disc front brake and drum brake at the rear deliver reliable stopping power, ensuring safety during every ride. With a generous fuel tank capacity of 15 liters, the F31 empowers riders to explore longer distances without the constant need for refueling. The motorcycle's compact dimensions, with a length of 2025 mm and a ground clearance of 120 mm, further contribute to its agility and ease of maneuvering in tight spaces. **
