How to back up your motorcycle on an extremely steep hill ( if you have to, can‘t go any forward ).bike is facing downhill and the bike is so heavy that there is no way to back it up normally. once you release the brakes the bike go forward really quick.
You have just realized one of the basic laws, Gravity,its a tough one to defeat. You have now learned a very important lesson, try to leave the bike pointed in the direction you plan on leaving. Next time butt the rear wheel against the curb and leave it in gear.
If you do get stuck in this position, you can walk the bike backward by using the front brake. Pull back on the bike as you release the brake, and reapply the brake when you've moved the bike as far as you can with a single pull. It might only be an inch or two. Repeat. It might take awhile, but you should be able to inch your way back up the hill.
There's no way to do it. You just have to plan ahead and not get into such situations. Or if you're already in that situation, get someone to help you. I have two bikes, and the bigger one is over 600 lbs. When I first got it, I parked it with the front wheel against the curb, and when I went to leave I found I couldn't back it up at all, just against the slight slope of the edge of the street. I noticed that Harley riders always -back- up to the curb, and now I realized why. 8^) So now I do that. I look at every parking space to see if it slopes downward at all, and if so I back into it.
