Yeah I'd also heard that CBR600s will run for a million trouble free km, most reliable bikes ever, etc etc... I just happened to get saddled with the one CBR that was an absolute piece of junk.
anyways, thanks for the advice. I know most 2 stroke cranks have a fairly short shelf life, and piston and rings need regular replacing, etc, i've no problem with that kinda maintenance, as long as the bike doesn't regularly have random breakdowns.
As for this one looks like it's been kept inside, the paint as i said is original (the red and white (terra, I think it's called?) colour scheme) doesn't seem to be a respray as it's a litte faded (but not badly so as it would be had it been kept outside). I'm sure it's been derestricted, most grey bikes here in SA are. Forgot how many km are on the clock, wil have to check, and ask about the previous owner and how well he took care of it.
There's also a MC21 I noticed for sale too... will check it out, also original paint and a good price too...
thanks again.
