Personally, I'd say skip both of those. Modern motorcycles break very rarely and payments on a $5000 bike are pretty low so you'd find some way to make them.
If the payment thing concerns you, you'd be better off putting $50 a month in a savings account. If for some unseen reason you need to use it to make payments, it's there. If not, you'll have some extra money to pay for mods, gas, etc., down the road.....
