A well set up NS400 makes just a little more power than a well set up NSR250! The NSR scores on weight and handling though, so would (fairly) easily pull an NS400.
The NS tunes very well however, and a Terry Shepherd 500 kit and kit pipes can really bump power and torque right up, although the 500 feels very "4-strokey" apparently. The NSR will still out-handle and out brake the NS though (depending who's on it of course!) so it's horses for courses.
Best thing to do is have both I say!
