First, you will need to find a set of wheels that are the correct size and width for your bike. The stock wheels on a KX125 are 19 inches front and 16 inches rear, while the stock wheels on a CR125 are 21 inches front and 18 inches rear. You can find smaller wheels in various sizes, so you will need to choose the size that best suits your needs.
Second, you will need to make sure that the smaller wheels do not interfere with any of the other components on your bike. This includes the brakes, suspension, and chain. If the wheels are too small, they may not provide adequate clearance for these components.
Third, you will need to be aware of the handling changes that may occur as a result of fitting smaller wheels. Smaller wheels will make your bike more responsive and easier to turn, but they may also make it less stable at high speeds.
If you are considering fitting smaller wheels to your KX125 or CR125, it is important to weigh the pros and cons carefully. You should also make sure that the modification is done properly by a qualified mechanic.
Here are some additional tips for short riders:
* Choose a bike that is the right size for you. The seat height should be low enough so that you can easily reach the ground with both feet.
* Adjust the handlebars and levers to fit your body. This will help you maintain a comfortable riding position.
* Use a lower-density seat foam to reduce the seat height by 1-2 inches.
* Get proper riding gear, including a helmet, eye protection, gloves, and boots. This will help you stay safe in the event of an accident.
* Take a riding course to learn how to ride safely. This will help you avoid accidents and injuries.
