The biggest moped event in denmark, with dragrace. I went on my Yamaha RD50 and got first place, with a bit of luck and a good running engine!
I joined some guys from knallertforum.dk to a ride with tuned mopeds and small motorbikes. I took my Gorilla to the ride, the other guys rode mostly Yamaha FS1 and Kreidler RS models. All heavily modified and registered as motorbikes, to make them road legal and fast.
Some video footage of the ride:
