Jun 21, 2021 · Wondering what grade gas to put in your motorcycle, or if a high-octane fuel will give your bike more power? This article explains what octane is and how it impacts your motorcycle engine.
If you’re wondering what octane fuel to use in your bike, it will be listed on a sticker on your gas tank, or you can find it spelled out in your owner’s manual. Whatever the manufacturer recommends is what you should stick with because that’s What your bike was designed to burn.

Octane is actually short for “octane rating” or “octane number,” a figure calculated through a few different methods. The number indicates how resistant the fuel is to detonation, which is when the air and fuel mixture begin burning prematurely due to heat and pressure, rather than beginning with a spark introduced at the optimum time by the spark ...
Well, if the burning of air and fuel happens too early, it will occur while the piston is still moving upwards in the cylinder. That’s sometimes too early to make power (and often actually robs it) and in severe cases, can damage the engine. The piston, rings, and ring lands usually take heavy abuse from detonation, and damage can even extend down ...
Traditionally, high octane fuels were used in large engines with high compression ratios, because high CRs foster the conditions that support detonation: high pressure and high temperature. So generally, an engine with higher compression will run with lots of timing advance to give that detonation-resistant fuel time to burn at high revs. Since all...
That’s a good question, and one that requires lots of information to answer even somewhat correctly. First, fuel availability affects what is built for a market. A built race motor may be designed to use 108 octane fuel, which is easy enough to procure before an event, but since that octane number is rarely seen for sale at dispenser pump in Americ...
Jul 5, 2022 · What octane does Harley-Davidson recommend? 91 octane. Every engine manufacturer specifies a minimum octane rating requirement for fuel. The majority of motorcycle engines, including all current Harley-Davidson engines, require 91 octane or higher (Premium) fuel, thanks to high compression ratios.
Mar 13, 2022 · Running higher octane won't hurt, but likely won't help anything, will just cost you more money. Running higher octane than required might prevent some pinging too if you have carbon build up.

What Octane is best for a motorcycle engine?
The octane rating is based on how much compression the fuel can withstand before it spontaneously ignites and causes engine knock, also known as pre-ignition detonation. The higher the octane rating, the greater resistance to ignition and detonation.
