Can someone please enlighten me: I know there's the NSR250 race replica, which is/was a street bike sold in Japan, and then there's the RS250 which is a real GP bike. But what about the NSR250 GP motorcycle that was ridden by Luca Cadalora, Biaggi, et al?
Were the GP NSRs predecesors to the RS250, or were they in production at the same time, and what would be the difference(s) between the street version of the NSR and the GP version?
Thanks and apologies if this has been covered before.
