I knew the Ridder . Its a long time ago . I dont get you wrong . And of course Novarossi is the Engine to Beat . But Novarossi got its price .
I will only say that there are some good engines too on the market . I get the Vegas for a good price and we are not slower . The BP´s are difficult for me after the experience I made with my engines .

For example ...I got 2 SM X21 from Schepis . I payed the engine 185 euro . Its an impressive engine . Very fast and very solid .
