I'm getting itch to beat up on litre-bikes in A-group this year. So RS250R with 100-lbs less weight (220-lbs) and triple power of my Ninjette will let me do that with shaving off 10-15sec/lap! 
It also costs less than track-prepped litre-bike, although I'm planning on sending 2-3x that on maintenance and rebuilds. With modern coatings and metallurgy, I hope to extend durability significantly over what was available in '90s. One of my clients who builds artificial hearts with mag-lev motors uses an off-the-shelf diamond-like coating that's +5x more durable than Nikasil. That's very promising for bearing-surfaces and cylinder walls.
Maintenance-schedule for RS250R looks like this from service-manual:

Wow every 500km for piston and rings, i guess i was hoping for at least 1000km How many miles/km do you tend to put on a bike for a track day and race?
