CBR's are easy meat for a sorted 250cc - 350cc stroker.
Also, given the outstanding handling of an NSR, you should be find.
About 6 years back I was chasing Andy down on an FZR600. Straight line speed the FZR was quicker but I don't think I've ever seen a bike go around a corner as well as that MC21 did, I was left for dead.
His MC21 wat pretty much stock then so a sorted NSR should eat up a CBF and fart out the pips
