That is comparing a full power RGV to a restricted NSR. Tables are reversed when you derestrict the NSR (MC16 / 18 / 21)

Don`t think that`s right 60hp out of a nsr250 mc16 is not easy.Yes you will get 60hp out of a mc18-mc21-mc28 with deristriction fairly easy and same with a rgv.
Ask 2stroke racers her in australia (not many around now)they tend to all say the same, Corners nsr, Straights Rgv`s. There is a few racers on this site from england they could tell a bit more as the 2strokers here are getting rare.
