Most motorcycle crashes happen to those with less than 5 months experience with the bike they are riding, regardless of experience.
Get to know your motorcycle, practice lifesaving skills - braking, swerving, turning.
Consider taking an MSF BRC2 or other intermediate "bike bonding" course on your motorcycle.
Consider doing so on a regular basis - spring tuneup for instance.
Most motorcycle crashes are between a motorcycle and another vehicle - 3/4 - vs single rider accidents, 1/4.
Most motorcycle crashes involving other vehicles are at intersections (not just places with stop signs/lights) while single rider accidents happen most often in curves.
2/3 of single rider crashes are rider error while 2/3 Motorcycle vs Motor vehicle are due to drivers violating MC right of way.
Most motorcycle crashes involving other vehicles occur within the rider's field of vision.
Stay conspicuous - add lights to the front and rear of your bike, dress in clothing more likely to get you noticed, position your motorcycle appropriately for conditions - be seen.
Remember that intersections are any place anything intersects with the road - play a constant "what if" and leave yourself escape routes.
Ride within your abilities, keep a margin of safety beyond what you think you need & depending on conditions.
Wear good gear at all times, I recommend full face/modular helmets.
Practice, practice, practice - especially braking from speeds you normally travel.
Motorcyclists will typically have around 2 seconds to make all of the collision avoidance decisions they will make.
Practice is critical, allows you to respond, vs react, whenever possible.
Ride your own ride at all times.
There are some good books out there, Lee Parks "Total Control 2" & Nick Ienatsch's "Sport Riding Techniques" come to mind, read up.

Practice doesn't make perfect, it makes permanent.
