What type of gas should I use?
Short Answer: Not Diesel
Long Answer:
A few people have seen the sticker on the bottom of their Ninja 250R seat that says:
FUEL: RESEARCH OCTANE NO. (RON) 91 MIN.
This is a little confusing since in America most of us have never heard of RON, and can easily assume that it means ‘Octane‘.
RON = “Research Octane Number”
MON = “Motor Octane Number”
If you take the average of the two, you get Octane. Page 32 of the Manual says “Use clean fresh unleaded gasoline with a minimum Antiknock Index (Octane) of 87″ — So, the good ol’ “cheap stuff ” (Use ‘Cheap’ losely there) should be fine.
*Note: If you are experiencing Knock — Refer to Page 33 of the Manual.
