Bike cover

[Gone in 60]

The Nelson Rigg covers (and I'm sure most name brands) have vents in them that are sort of hooded, so that rain and stuff doesn't get into the vents. It really doesn't matter what kind of cover you have, it's not sealed, and you'll get condensation and moisture on the bike. Being under a carport will help you. One bike I bought a long time ago came with a Dowco cover that was made of very heavy material that looked quite substantial.

One thing I do to protect my windscreen from scratches from the cover shifting around on it is to wrap a microfiber towel around the screen before putting the cover on. Not sure if this would be applicable to you.
