There are plenty of guys on here that use our bikes at those kinds of speeds almost every day. for months or even years without issue. I guess it really just depends on what is considered prolonged, but mine survived an over 10 mile run at 60-65mph twice a day getting me to and from work. There are plenty of other guys here that run their bikes at those same kinds of speeds all of the time. There is a reason most of us that do use our bikes like this tend to gear them more like a road bike to try and bring the revs down. My last bike would sit in the low 6000rpm range at 60mph without the throttle having to be wide open, and do so quite happily for long periods of time.
