By lack of credit, what do you mean? Never had a loan or credit card? Or is there a something in your past credit history?
Dods is correct, a secured credit card is a good start, I have seen them extend full credit in as little as 6 months. You may also try getting some store cards, buy something and pay it off several times. Credit reports show your payment history, Current, 30, 60, 90 days late. Any late payments are noted and often an explanation will be requested.
Secondly when underwriting a loan, several items are weighed, although credit history is the most heavily weighted in a vehicle purchase. Two ratios come into play, Loan to value, most banks will only loan up to 80% of the purchase price (Value) This ratio will sometimes go down with the age of the vehicle (depending on the lending institutions loan policy). Second ratio is "Debt to Income", simple to figure out, take your rent/mortgage and any other monthly loan payments, add them up and divide that by your monthly income, if the answer is greater than .42 (42%), it may be difficult for you to get a loan. I have underwritten car/motorcycle loans for customers with little or no credit history, but had to sell them to my boss's for an exception, I was able to do this as the customers ratios were well below the thresholds. When a loan is approved outside the lending policy, usually requires at least two officers of the lending institution to approve, and it has to be a well documented reason for the exception. This is all due to the fair lending rules, if you make an approval outside of policy you have to have a good reason and demonstrate that you weren't making the exception for any other reason than that it makes good business sense. FDIC auditors and other govt regulators will find it and want documented proof that the loan was made for legitimate reasons.
Most of the manufactures offer financing and often their lending policies are less stringent than a banks making get financed much easier.
Looking at Kawasaki's web site looks like they offer financing, but I dont see an online application. Honda does have an online application, and from where I am sitting the CBR300 is not a bad looking bike. With a $2000 down a ~$4600 motorcycle, you may just get the loan with a limited credit history. You should try to get pre approved through one of the manufacturers finance programs, aside from knowing you can get a loan it also gives you a little more bargaining power when making the purchase! I hope this works out for you!
