Personally i don't put anything less then 91 Octane in my 250. Just put 94 in and it felt different, but that could just be all in my head. ^_^

The way i look at it, gas for a bike is hella cheap, $10-15 a fill, why not put the best in 'er?

Using higher octane fuel that is recommended or needed isn't an advantage, and it costs you money and power. Octane controls detonation, that's it. If you don't need it, more octane is a disadvantage.

Use what is recommended in the manual, nothing more. Stay away from Ethanol. Use Premium only if it's the only grade without Ethanol (if it's not required). At that point it is even - you are gaining something by eliminating Ethanol but losing something by running more octane than needed.

Your cycle may run better on Premium, but chances are it's because it doesn't have Ethanol like the Regular grade - not because of increased octane.

You shouldn't use 87. These are high PERFORMANCE machines. You give it the best quality gas you can. Personally, I use Sunoco 93 and it works great. I wouldn't recommend cheaping out on the gas you buy. Many gas companies have watered down fuel so choose a big name gas station.

It depends on the specific engine. Read the manual, and use what it recommends! There nothing wrong with 87 if that's all you need!

The "quality" of Premium isn't gaining you anything. The only "watering down" is the addition of Ethanol. Use a quality gas, but don't think that using Premium when you don't need it is getting you anything.

Research Octane Number (RON) is the most common type of octane rating worldwide, however in the United States octane rating is displayed in AKI (Anti -Knock Index). The RON Rating for regular gas in gasoline in Australia, New Zealand, Canada and the US is 91-92 which is the equivalent of 87 AKI (octane)

Despite the fact that a higher octane may make and engine feel like it runs better, there is some evidence to the contrary that may be of some use. Higher Octane does not always equal more power. This is a good article from Motorcycle Performance "Home of the World's Fastest Ducati. Bad Gasoline
Some of the same facts that they point out, others point out as well

Interesting link.

I've know the owner (Bill) of that shop for 30 years, and spoke to him about it not long ago when I was there.

His info agree with what I have gathered from other sources over the years.

It seems that 87(AKI in the US) without ethanol is best gas to use, would you concur Jay? ☺

We only get 95 or 97 Ron (super unleaded) here ,I remember reading a bike magazine review where they tested the same bikes with each grade and the biggest power increase was in a Honda sp2 it made 1 bhp more on super than normal but most of the 4 cylinders made no or very very small increase in power ,they did recommend running super unleaded if the outside temp was getting high though!
