I've had this bike for a while now and have fallen in love with it! Looks the part and performs like a dream, especially for a 50cc! The engine is amazing, getting 70-80 mph out of a 50!! With Yamaha quality and reliability is a given, so nothing to worry about there. It is the size of a 125 or 250 as it uses the same frame and therefore dwarfing other 50's. The only down side is that it isn't made for the UK market therefore only imports can be bought, unless you plan on going to Spain, which would be nice I suppose. Yamaha should defiantly bring it to the UK market as it would be a instant success as everyone I know asks where to get one! I've ridden plenty of 50's and this is a whole 2 miles better than any other! Everyone who has been on mine as said it is the quickest 50 they've ever seen. So overall it is undoubtedly THE BEST 50CC EVER MADE!
