Leave the cover off & preserve the paint! :thumbup:
The paint's softer than you might think, and anything covering it that will move or flap
AT ALL for any length of time
WILL damage it!! I've seen a Spyder that'd been covered with a (fairly?!?) tight fitting, specially lined, & advertised as suitable for covering vehicles being towed cover that had many biiig wear blemishes rubbed into the paint after just 1 hour of towing at 'around town' speeds - so not even Freeway or Long Distance Travelling speeds, just 35 mph or so for about 1 hour & the paint work was destroyed!! :gaah:
So just leave the cover off & preserve the paint! It'll be no harder to clean the bugs & road grime off than it would be if you rode it that far :thumbup: . Besides, cleaning it sure beats getting it stripped back & repainted!
