As a new rider, I may be a lucky guy but I have not dropped my bike yet, however, I have followed strictly some guidelines:
1-) I learned to ride in a very small and light bike according to my size and weight (5'5" 140 lbs), the Grom 125cc. I passed the California DMV Motorcycle driving test on this baby. But first, I learned how to ride at very slow speeds of 4 mph not putting any foot down, I practiced doing lots of "8 shape" turns with the bike, how to do emergency breaking, how to push the bike on different surfaces, going up and down, getting it in and out of my driveway and my garage and many other things that are a must to handle properly a bike.
2-) Never attempt to move the bike wearing sandals! You must wear motorcycle boots
3-) Always park the bike on a flat surface with no gravel, water, oil, etc.
4-) If you don't have enough space in between stopped cars, do not enter, go around or wait behind the cars.
5-) When pushing the bike stand on the left side of the bike, make sure 1st gear is engaged, pull the clutch, push the bike slowly and as vertical as possible, never lean it to the right side.
6-) Never move or ride a bike that you are not comfortable or able to handle. It took me months to master the Grom 125cc and then I moved to the CB500F and I had to re learn all over the same related things to the CB500F for its size and weight. The Grom weights 220 lbs the CB500F weights 420 lbs.
7-) Never pull the front brake while turning the handle bars.
Pay full attention while you are pushing your bike, you are moving a 500 lbs or more piece of metal that may hurt you or kill you. Don't get distracted by anything while going at slow speeds.
At the beginning ridding the Grom was the biggest bike that I could handle or ride, after I mastered the Grom, now the CB500F is becoming a Grom, soon I may move to the CB650R in the future but I already test drove the CB650R and it is super intimidating for me for 2 reasons, the clutch is very hard and I'm tippy-toe. I may easily drop it.
