Unless you have a dedicated track bike with an ECU map and engine modifications that requires race fuel, you don’t need it. 93 octane ethanol-free is just fine. It’s all about what the compression is in your engine; higher compression means that you need higher octane fuel, and higher octane fuel in a lower compression engine isn’t helping at all. (Most modern bikes also have anti-knock sensors that will retard the timing if your fuel is too poor for the engine.)
