The JETSURF (RCMK Motojet) 100cc Twin inline engine prototype engine first running test

Our company RCMK started to develop the motorized surfboard 2 years ago. We decided to develop the new engine for motorized surf board. So, we made the prototype 100cc twin inline engine for our motorized surf board Motojet at last year. We will release our perfect 100cc twin inline engine within this year 2017.
