You need to work on your brakes. The rear should nearly lock-up and the front should just about put you over the handlebars. IF you're going to run 60 on a moped, you have no excuse not to mod it to disc brakes.

Maybe you weigh 300 lbs...…………...after all it is inertia and that is physics. Below,make sure you read the last SIX WORDS.

What we need to look at is:

If you have a 2,000 kg car (which is about 4400 lbs) that is driving at 10 m/s (or about 22 mph), you would have a kinetic energy of 100,000 Joules. If you doubled your speed to 20 m/s (which is about 45 mph), your kinetic energy would be 400,000 J. In this example, it is clearly apparent that higher speeds will result in higher energy crashes. By doubling your speed, you increase the energy in a collision by FOUR TIMES, which makes it significantly more dangerous.
