How to build a powerful motor: all the know-how!
My team and I have been working on this engine for a whole year: we've applied all our experience, brought in top specialists, and used unique equipment.
All this has allowed us to build not only a powerful engine, but also a reliable one!
Specifically, the engine helped us win the Lider endurance race and take second place in the 2023 Supermoto.ru Minimotard Championship.
Watch our other videos about building racing pit bikes!
Minimotard is the most accessible and popular class of road racing motorcycles.
