If you are at the initial stages of acquiring driving skills, you must not ride smaller bikes because your weight can drastically impact the suspension system, and you can lose control and grip.

You must understand the importance of bike selection, and two individuals can not get the same comfort level while driving the exact vehicle. Two persons having different weights can not experience the exact extent of fun while riding the same bike.

If your weight is around 150lbs, you must choose a motorcycle having a capacity of around 250cc. It would be the best choice for you, and it would not put additional strain on suspension. 

You can enjoy the fun of the ride. If the rider’s weight is above this limit, it should be best for him to go with the selection of 450cc.

But it would be best if you had an idea about the power of 450cc, it Is very powerful, and you have to control this. If you are a born rider and acquire the driving skills proficiently, you will have a fun experience selecting this bike.
