I feel a little rediculous for even asking this but I have too. I picked up a 660 today and I asked a ton of questions about the bike, but forgot to ask what kind of fuel it runs on. If anyone could help me I would greatly appreciate it. As far as the bike I really love it, the acceleration and handling are all that I read about. For a 1st bike some people say its too much.. But I'm a big guy and I dont intend on going crazy..Thanks alot

 

If it's stock then it just runs on pump gas.....if it had a high comp. piston then you would need a little higher octane.

 

OK thank you very much..

 

11:1 piston u can run pump/race fuel---- 12:1 piston u need to run strait race gas.something like vp's c-12(108 oct)

stock -id run 93 octane!! dont get cheap,atv's dont use that much gas.
