Not sure if this counts as "touring bits" but how about laser eye surgery? I had a light prescription but it's bad enough for me to have to wear glasses while riding/driving. Glasses makes the pinlock on my helmet completely useless as even though the visor didn't fog, my glasses did.
I had no idea how cheap Lasik is these days until a co-worker got it done told me about it. To give you a bit of an idea, my prescription was 1.25 and 1.50. My price was $490 per eye. I opted for a 5 year warranty at an additional $500 for an all in price of $1530 (including the eye drops & no taxes are applicable). I got my eyes done this past weekend and I'm looking forward to my first ride without glasses.
Putting it out there in case there are people still think laser eye surgery is expensive.
edit: oh and ROK straps. Everyone should have these handy.
