Not going to play "mine's bigger than yours", but mine has made more than 67hp on OEM pistons and stock porting, and will do considerably more than 1000 miles before needing the top-end to be pulled.

Nothing wrong with what you guys are saying, but in my opinion you haven't found the Holy Grail of cheap, long-life, lightweight, single-ring pistons... there is no such thing. Yes, the RM pistons are initially cheaper, but if you have to replace them twice (at least) for every set of OEM pistons, and the ring 3 times (at least) as often as OEM rings, then ultimately they are more expensive... and performance is ALWAYS ultimately MORE expensive.

Bear that in mind when choosing.

I say that if you have 2 NSRs (or more!) then build one that's all singing all dancing, with single-ring pistons, ported to hell, with pipes and a trick ignition, and keep one that will run almost forever, as you'll soon get pissed off pulling the top-end! We all love spannering now and again, but it will soon start to become monotonous when you are spending more hours replacing bits than hours riding.
