I'm thinking of buying my friends CG125 2015 that has around 20000kms on odo.Engine was tuned along with oil change about 6 months ago and bike has been sitting withoud fuel for a month. The only problem is that he rarely uses his bike and its been sitting in his garage without shade or cover. Due to this the chrome has faded on parts but bike is not rusty. Is it worth buying and restoring his bike? What should I check before buying?
