The search for perfection | Messner Moto

Mirko Mesner, founder and designer, has been in love with the automotive design since the early 2000s. His dream and passion was to design and build high-performance cars and motorcycles. The dream was big and frightening but step-by-step Mirko, having a strong background in computer science, taught himself industrial design, mechanical engineering and any other necessary skill needed to make his dream come true. 

From the beginning of his quest, he started designing cars and motorcycles in 3D software hoping that one day all his effort will pay off and he will be able to start a project for real. Unfortunately, major obstacle for realization of his projects was financial resource. Building this kind of projects, with an obsession for perfection, demand huge amounts of financial support. After 10 years in IT industry, Mirko managed to save enough money in order to started building his first project. 

The moment he saw Honda CB750, he new that this will be his dream project. After choosing the right bike, he focused all of his spear time and resources in building his first motorcycle prototype based on CB750. It took long and stressful 3 years to design and build the bike, but at the end, he made it. The end result is perfection in motion.
