Actually, I read it 
And I agree with you. 200kmh is quite easy; although on Malaysian
trunk roads, I've never been able to go above 180 for long. The
road either bends too much, or there's traffic ahead.
Personally, I don't think 60kmh in a Kart is scary.
Down the main straight at the Permas track, in a 100cc kart, it
does take quite a bit of guts not to lift the accelerator when
negotiating the downhill lefthander at the end of it. I've had a
lot of fishtails and a couple of spin outs there, but it sure is
FUN!
