The 11F was a good looking efficient and deservedly popular machine . Its 989cc V-twin engine was good enough to produce good power and speed. The bike had no front brake and only a crude expanding band on the rear wheel. Its two speed gear box was operated by hand using a lever to the left of the tank. Its hard trail frame had sprung saddle and “Ful Floteing” Seat posture design gives rider a good comfort.

This bike seems like a classic gem with its unique features and design. The 989cc V-twin engine must have been a powerhouse for its time. The lack of a front brake and the crude rear brake system sound quite adventurous. The hand-operated two-speed gearbox adds to its vintage charm. How did riders manage the balance between speed and safety with such braking mechanisms?
The 11F sounds like a fascinating piece of engineering history. Its 989cc V-twin engine must have been quite impressive for its time, especially with the power and speed it delivered. The lack of a front brake and the crude rear brake system seem risky by today’s standards, but it’s interesting to see how motorcycle design has evolved. The two-speed gearbox operated by hand adds a unique touch, making it feel like a true vintage experience. The Ful Floteing seat design must have provided a surprisingly comfortable ride despite the bike’s simplicity. I wonder how it handled on rough terrains or long rides—was it as reliable as it was stylish? What’s your take on how this design compares to modern motorcycles?
