Yep... gps gives u current speed and i can tell u, original gauge gives u 180km/h easily, but gps is telling about 145km/h... For full power Cagiva. With 15hp it goes something like +- 120km/h. Which is not very useful if you are looking for big roads. Considering u could have those 33hp/145. :)
But in the end, its very easy to ride and with good care it will not explode in your face. I recommend !
