Decided to take advantage of the 1.9% on a small balance only until I sold the second interstate and that happened 5 weeks later. Finance at the dealer told me that the credit score level had to be higher than buying a car saying that it is a recreational vehicle. Never heard that one before. Pulled a 830 so the 1.99 was in the bag. Now is what he said right?? What if I drove it to work as my only transportation?

Yes, that is correct. Automobile loans are considered secured loans - they use the (resellable) value of the car itself to secure the fact that the loan will be repaid. If the loan is not repaid, they repossess the car and sell it to regain the value of the loan.
Motorcycle loans are considered unsecured loans, the equivalent of a personal loan. They do not give the asset you are borrowing for (the motorcycle) any value in terms of repossession because they feel / know that motorcycles are more easily damaged or stolen, and can be made to quickly disappear. Unsecured loans are given at the highest interest rates as the bank feels they are a higher risk.
