get a Cagiva Mito
imo thats the nicest bike
and i dont think the engine on a RS125 will break that easily. I have a friend that have the same bike and he has been very rough with the cycle, driving-vise
and it have not broken down once(yet)
and my bestfriend have a Mito and have just rounded 13600 km, got the cycle one year ago(and he drove most of it on the winter) and it still havent broken down
