Jacket, helmet, gauges, stereo, starter button, kickstand, shifter, clutch... in that order... now based on how many miles I've ridden, and how the bike feels while riding i will inspect the chain, the brakes, etc... tires usually get checked once a week if riding a lot, chain gets lubed once a week or every 2 weeks depending on miles and weather. I've gotten to know my bike very well over theast 40,000 miles, I can feel or hear pretty much anything going on with the bike before it becomes a MAJOR problem.
