most likely regular but if you race u might want to use a higher octane gas
93-95 octane recommended
Unleaded pump gas. I run 91 octane in my 525 KTM.
50:1 mixture
if you have a 4stroke dirt bike you run straight gas ,if you have a 2stroke dirt bike you run mixed gas
93 octane
Each car should have a recommended fuel octane in the owners manual.
32:1 is a great gas to oil ratio for any two stroke motocross bike. Also, a Ratio Rite is recommended for accuracy and simplicity.
87 octane
87 octane.
there recommended for 92 octane or higher with you should use premium gas witch is 93 octane
87
regular 89 or lower octane gas.
