From Tinman:

I have found a battery locally that fits our bikes. It's an Interstate battery CYTX12-BS, runs about $60.

Update:

The Interstate Battery website also lists a second battery, the FAYTX12. The online prices seem to be $10-20 more than what your local dealer is getting for them. My local dealer said the difference is the FAYTX12 is all charged up and ready to go. -FriarJohn
