I'd take an NSR over the RGV anyday.
The first NSR I saw was at Mallory Park in 1990. It was an MC21 racing in the proddy 250 class and got it's arse severely kicked by the KR's and the RGV's. It siezed if I recall and was never seen again.
Oh how we laughed at the so called race replica from Japland.
The next NSR I saw was at Bira International Circuit in Thailand, in 1993. I was to be riding an F3 RGV250 against F3 TZR's and a full HRC F3 NSR250. I spent most of the time at the circuit ogling this F3 NSR. Pure WOW! Ridden by multi Thailand Champ, Asian Champ and 5 times Macau winner Christmas Vilairoj.
I broke two RGV engines during practice then tossed the thing into the tyres while in third after about 4 laps. The F3 NSR cruised to victory, most of the time spent on one wheel. After that day I vowed to get an NSR250, take on the world and dominate.
I have never even contemplated racing an RGV since that day, and have only ridden the RGV to test pipes, even though we've had a couple, including a very fast F3.
