So since my last bike had little to no plastic on it, the first thing I noticed was the massive amounts of black plastic on my C14....I bought a cover and wondered if I should start covering it every day to try and keep the sun from killing it 
In addition I bought some black magic plastic and vinyl treatment, suppose to work against UV rays, etc...just wondering what everyone else is using/doing to keep the black from drying out and becoming oxidized?
I understand your concerns. I had an '85 Honda Magna 3 months in the garden with no caver whatsoever, and the paint afterwards was clearly faded
I never left a bike outside for longer than strictly necessary after that experience. My 1400GTR now has three possibilities:
1. she's in the garage at home,
2. she's in the garage at work (big company with special MC garage, ventilated, surveillance cameras, etc.),
3. she's with me, rolling.
If I do some errands and such, I try parking her on the shadow of the buildings if possible. I don't think she has been more than a few hours really static under the sun since I bought it 30 months ago. And it's not just because I became paranoic
. The black painted plastic get's HOT, cracks and whatnot, and I'm planning to keep this bike for looooong while.
