I do 140km a week on my Aprilia on £5 of unleaded with a tad of octane booster in there for good measure, keep it in good nik by keepin it tmeperate, dry away from sunlight (tyres perish) clean it regualrily also, i have found if u put plumbers insulating tape on area prone to rubbing such as the frame it keeps it in tip top condition and scratch free :D hope this helps
