Not that many changes on the Langster over the years other than the appearance. Me - '06. Caned the crap out of mine for 5000 miles and my maintenance beyond cleaning and puncture repair has consisted of repairing a broken spoke and a quick wheel re-truing (oh and BB needs replacing currently).
Admittedly you'll want to change bits as you go but that's personal preference.
