before i bought an nsr i was deciding between the nsr & the rs125, i´ve never riden a rs125 & now im somewhat wondering if i should have bought one of them insted, my nsr is pretty good, easy to ride but needs derestricting beacuse it only does around 80mph & it takes ages to get there but i´ve heard they do around 110mph when derestricted i think the rs125 does around the same. well i hope this helps.
