Which brake do you use the most when riding a motorcycle?
Yes, and inflate them to the proper pressure.
Yes you should buy new tires ment for driving on the road. i have worked as a mechanic for a couple of years and any mechanic would know you never drive mudding tires on flat pavement, it actually puts more stress on your motor and your stubs on the tires get worn down while driving, so i would get new street tires
I try to use them together. But there are exceptions, and that's why most motorcycles have separate back and front brakes. (Ever think about that? Cars don't have separate brakes for each wheel!) My old bike, which I've had since 1983, is a BMW with a single disk in front and a drum in back. That bike, I put the back brake on first, then the front (unless it's a 'panic' situation, then they both go on at the same time). I learned on bicycles years ago to put the back brake on first to increase stability. My new bike is a Honda ST1100 with dual disks in front and a disk in back, all hydraulic. I had to get out of the habit of putting the back brake on first, because it would lock up and the back of the bike would fishtail. And then I'd have to change my pants. 8^ For the first few months I owned this bike I was just AMAZED at how much better motorcycle brakes had gotten in 20 years! I would be thinking about this as I changed my pants. On either bike, of course, the front brake does most of the braking. In fact I know bikers who never use their back brake except in panic situations. Also, if you're going around a curve, you can 'drag' the back brake for stability. If you find yourself in the situation of being in the middle of a curve when you realize you're still going too fast, the back brake is safer than the front brake, but you can still lose traction and slide out if you brake too hard too suddenly.
The two brakes have different primary functions. If you're looking to dump speed (e.g. you're at 50mph and need to stop at a red light) you mainly use the front brake - 75% of stopping comes from the front brake, 25% comes from the rear brake. Normally I put the front brake on just before the rear to shift the weight of the bike on to the forks. If you use too much rear brake you will skid and fishtail. But anything to do with control is the domain of the back brake. So for slow riding, e.g. in traffic or for a U-turn, you dab the back brake. If you try to use the front brake the weight shifts to the forks and you lose stability at slow speeds. Also, hill starts become infinitely easier when you stop using the front brake to hold the bike on the slope and start using the back brake instead. Overall, the front brake is probably used the most, although it would depend a little on the type of riding you do.
Front brake is used about 75% of the time, rear brake about 25%. Thats why they usually wear out faster.
