Interesting read, those NSRs look fantastic! What's it like riding these sort of bikes in a group - presumably rider skill is more apparent on bikes like this than the 4 strokes that I'm used to (which I seem to be able to get away with murder/show up much larger machinery on). Or does the owner's list of spec parts really come into the equation?
I've only seen 1 NSR250 before (from a distance, the owner was mobbed at Box Hill) let alone seeing 4!
