Is there any FAQs or anything where I can learn some more about the bikes? I was looking at a NS250R and a 1987 NSR250R this weekend and they seem to be exactly the type of bike I am looking for... Very light, while still retaining some sporty power and handling characteristics.

I have gone over the model histories and specifications and have think the MC 16 like the 1987 I looked at would be a good choice.
What should I look for when purchasing these bikes, what is the parts availability and what bikes two strokes and four strokes are in the same range for power and weight?
How much should I expect to pay Canadian and is there much of an aftermarket parts industry?

After further review I now believe the bike is the 1987 NSR250 in Fighting Red
