Realizing that the manual for the S50 and Intruder VS800 call for 87 Octane gasoline to be used, I believe that many times the octane rating can be wrong and to use lower Octane could, at the very least, cause a loss of power. I have been using 89 Octane. Is there any advantage to using 93 Octane? Any chance of damage to the engine using 93 Octane? Is going from 89 to 93 Octane simply a waste of money? Since I am getting right at 50mph, the additional cost of the higher Octane is not important.
