Speed vs rpm

Hi Guy's,

I don't know if it has been asked before, can't find it, but what speeds match to what rpm range?
Let say the say 30, 40, 50, 60, 70 mph?
I ask because I was wondering if you can judge the wear of the belt and/or drive line from that?
Out of the top of my head I get about 5500/5700 rpm at about 70 mph, is that about right?

Yep, that sounds about right bud, 5000 shows as 65 mph on my speedo. There is an orange warning light that tells you when to change the belt.

FWIW I am running (4) 24 g and (4) 26 g DRP sliders, 5k rpm = 70 mph (indicated)...

That sounds about right Leroi, but I wouldn't rely on the revs variation as to when to change your belt. In all probability the deterioration will be too gradual for you to notice and the nature of cvt transmission is the you can get different revs due engine loading (up hill or down hill for example).
Either change it at the recommend intervals (safest option) or check for cracks and measure the width as per the manual.
