Motorcycle rental in S. Korea?

I'll be travelling in S. Korea for a couple of weeks and will be going to the Busan area.  I have an international drivers license with a motorcycle endorsement and I was wondering if there is any locations that rent motorcycles anyone knows of?  I'm not looking to rent a scooter - I've found a few of those, I'd really prefer a motorcycle that is 500 CC's or larger.  Any help you could provide would be much appreciated!
