Who we are

We are two brothers who are vehicle-, engine- and race-enthusiasts. Our dream over the years has been to be self-employed.  With our previous corporate experience, we realized this dream of offering individual solutions for sport motorcycle riders. We specialize in the management of the complexities of engine management systems.
