Hey, it's John here from the San Fernando Valley, Los Angeles and new to the group.
I've got the same bike 2013 model and been wondering about this as well. What about cruising around 75 mph? Tach is just touching the red. Is there a rule of thumb for how long to keep up higher RPMs before serious wear kicks in? Just hit my 4000 mile service/oil changes and engine oil wasn't too dirty.
I ride the LA freeway everyday and routinely hit 80 & sometimes up to 90 to get out ahead of traffic or pass. Even in 80's I've never noticed the Tach higher than 8500. Only keep it there briefly and then back off to my 70-75 cruising speed- Tach just at or under the red.
Commute is pretty short- like 10 min on FWY. Rest of the time just street speeds.
In my mind, this should be ok and I think the bike is made for this kind of speed/rpm, but I've been wrong before as my ex loves to remind me.
Thanks for your feedback.
