I have a yz450-f and I use racing fuel, its more expensive but it keeps the engine much cleaner over an extended period of time, however this is not nessasary, in my old 250 i use regular unleaded and its been working fine for years now. So basically, since its just an 80cc, regular unleaded will work just fine, but if you want to extend the life of your engine, i reccommend racing fuel
