I have looked at a number of trail ride event videos as well as technical appraising riders of various SxS and many of them linked to by "SKELLEY521 " Kudo's, nice viewing. Crawling and struggling threw mud water bogs and climbing river side shores got to be hard on them. I suspect all this is in low gear. Nothing is mentioned about anyone's belt overheating throughout the events not blowing. Could it be Yamaha has in fact factored this usage into their design.
