Regardless of what you decide to do about the bike you should start establishing credit if you plan on taking loans for big purchases such as vehicles and houses. You must be responsible with it but you should have at least two credit cards, preferably from different banks. Use them occassionally and pay them off in a timely manner. Some will tell you not to worry about credit cards because you shouldn't use them. However having a good established credit rating and a credit history can save you hundreds or even thousands of dollars by getting you a better rate on loans. It doesn't matter how good of a job you have or how secure the loan is because if you don't have a history of responsible payment of debt then your loan rate will be higher.
