How to Alter CG 125: A Comprehensive Guide
In the realm of motorcycle customization, altering the center of gravity (CG) of a CG 125 motorcycle can significantly enhance its handling and performance. The CG 125, a popular motorcycle model known for its reliability and affordability, can be transformed into a more agile and responsive machine through strategic modifications. This article will provide a step-by-step guide on how to alter the CG 125, ensuring that riders can enjoy a more dynamic and enjoyable riding experience.
Understanding the Center of Gravity
The center of gravity is the point at which the weight of an object is evenly distributed. In the case of a motorcycle, the CG is the point where the motorcycle’s weight is evenly distributed between the front and rear wheels. Altering the CG can have a profound impact on the motorcycle’s handling, as it affects the bike’s stability, cornering ability, and overall agility.
Step 1: Evaluate the Current CG
Before making any changes to the CG 125, it is essential to evaluate the current CG. This can be done by placing the motorcycle on a scale and measuring the weight distribution between the front and rear wheels. A balanced CG typically has a weight distribution of around 50/50, with some variance depending on the rider’s weight and riding style.
Step 2: Identify Areas for Modification
Once the current CG has been established, identify areas where modifications can be made to alter the weight distribution. Common areas for modification include the swingarm, rear suspension, and exhaust system. Each of these components can be adjusted to either lower the CG or raise it, depending on the desired outcome.
Step 3: Lowering the CG
Lowering the CG is often the goal for riders looking to improve handling. This can be achieved by installing a lower swingarm, which brings the rear wheel closer to the ground and lowers the overall center of gravity. Additionally, swapping out the rear suspension for a set with adjustable preload can help lower the bike further by reducing the amount of weight on the rear tire.
Step 4: Raising the CG
Conversely, raising the CG can be beneficial for riders who prefer a more stable, less agile motorcycle. This can be done by installing a higher swingarm, which increases the distance between the rear wheel and the ground. Raising the CG can also be achieved by increasing the amount of preload on the rear suspension, effectively shifting more weight to the rear tire.
Step 5: Installing an Exhaust System
Another way to alter the CG is by installing a new exhaust system. A lighter exhaust system can lower the overall weight of the motorcycle, thereby reducing the CG. Ensure that the new exhaust system is compatible with the CG 125 and meets all local regulations.
Step 6: Test and Adjust
After making the necessary modifications, it is crucial to test the motorcycle’s handling on various types of roads and terrains. This will help you determine if the changes have achieved the desired outcome. If the CG is still not where you want it, make further adjustments to the suspension or swingarm until the desired weight distribution is achieved.
Conclusion
Altering the CG of a CG 125 motorcycle can be a rewarding and enjoyable process. By following the steps outlined in this guide, riders can achieve a more balanced and agile motorcycle that is tailored to their specific needs and preferences. Remember to always prioritize safety and ensure that any modifications comply with local regulations and standards.
