My motorcycle is a 2004 Honda VTX Retro 1300. I’ve added just about every accessory to it. Custom Ultimate seats with backrests, Highway lightbar and highway sidebars with extended foot pegs, air horns, saddle bags, custom cobra exhaust pipes, Garmin Zona 450 GPS, and a lot of chrome trim.
I’ve used synthetic oil from day one. With over 35,000 miles on the bike, it seems to run smoother than the day I purchased it.
