110 pocket bikes are miniature motorcycles. CC stands for cubic centimetres which is the measurement of volume in the cylinders of an engine. For instance a 1l engine is 1000cc. To get the volume in each cylinder divide the total volume with the amount of cylinders. If the above 1000cc had 2 cylinders then 1000/2=500, which means 500cc per cylinder.
An average 110cc pocket bike will be somewhere around 50 inches long and 20 tall. It will typically have an gas powered engine. Most of these bikes are built for speed.
The bike will typically have most of the features of a full size racing bike, which makes sense since they are the top of the line of the mini GP bikes.
Most 110cc pocket bikes are designed to be used on a closed course. As such they can be said to be dedicated race bikes. It is advisable to buy a quality racing bike since you don’t want to have a cheap knockoff with parts falling off at high speeds. Maybe not the best bike for absolute beginners and kids without any riding experience, they will last you a long time if maintained properly. Since they are some of the fastest pocket bikes you probably wont need to upgrade any time soon.
