Yeah-don't go to the dealer (depending on where you are in MI we have Life Cycle and Detroit Triumph).
Oil filter was $13 (I put a K&N on) and oil was ~$30 for me this year. I would do like all before me said. Really your not looking at a lot of money, seeing how you got a killer deal on the bike. But definitly get a manual and read over all these sections and the recommended fluids etc. I got mine here for a little cheaper. Becuase I'm cheap!
