I guess time will tell. I’m just going off what I have experienced over the years of running every one of my bikes well north of 300 deg regularly when rock crawling. My air cooled XR 600 topped out over 330 degrees. Ironically it was the only bike that ever left me stranded. Engine locked up from an oil related failure (frame drain plug fell out).Huh? The coolant is cooling the cylinders and cylinder heads, it does not directly cool the clutch, am I missing something? Also, clutch friction (when slipped) can generate temperatures well above coolant temps. I don't think there are any internal combustion engines designed to operate at 300F.
I have run temperature strips on my clutch and a coolant gauge. When going super slow for long periods the numbers end up matching. For short bursts of clutch abuse then yes the clutch pack only gets hotter.
The good news is I got rid of my 300 and no longer doing super long stupid trails anymore. I’ve decided to keep running Evans in my Beta and OEM Yamaha coolant in my Super Tenere.
