Why I Believe a 125cc Big Bore Kit is Necessary

As a motorcyclist, I have always been interested in finding ways to improve the performance of my bike. One of the most effective upgrades I have come across is installing a 125cc big bore kit. This kit increases the size of the engine’s cylinders, resulting in a significant increase in power and torque.

Firstly, a big bore kit allows for more air and fuel to be compressed in the engine, resulting in a larger explosion and more power. This upgrade is especially beneficial for smaller engines like 125cc, as it can give them a similar output to that of larger engines without having to switch out the entire engine.

Additionally, a big bore kit can also improve the overall longevity of the engine. With more power being produced, there is less strain on the engine as it doesn’t have to work as hard to achieve the same results. This can lead to reduced wear and tear on internal components, ultimately extending the lifespan of the engine.

Moreover, installing a big bore kit can also enhance fuel efficiency. With increased power and torque, less throttle input is required to maintain speed, resulting in better gas mileage. This not only saves money on fuel costs but also

My Buying Guide on ‘125Cc Big Bore Kit’

As a motorcycle enthusiast, I have always been fascinated by the performance upgrades that can be done on my bike. After doing some research, I came across the 125cc big bore kit and decided to give it a try. In this buying guide, I will share my first-hand experience and provide you with all the necessary information to help you make an informed decision when purchasing a 125cc big bore kit.

What is a 125cc Big Bore Kit?

A 125cc big bore kit is an aftermarket upgrade for small displacement motorcycles that increases the volume of the engine’s combustion chamber. This allows for more air and fuel to enter the engine, resulting in increased power and torque. It typically includes a larger cylinder, piston, rings, gaskets, and sometimes a new camshaft.

Benefits of Installing a 125cc Big Bore Kit

1. Increased horsepower: The most significant advantage of installing a 125cc big bore kit is the increase in horsepower. Depending on your bike’s current engine size, you can expect to gain anywhere from 10-20% more power.

2. Improved torque: With more air and fuel being able to enter the engine, you will also experience an increase in torque. This means your bike will have better acceleration and overall performance.

3. Cost-effective upgrade: Compared to other performance upgrades like changing exhaust systems or adding a turbocharger, installing a 125cc big bore kit is relatively affordable.

4. Easy installation: Most big bore kits come with all the necessary components for installation, making it easy for anyone with basic mechanical knowledge to install themselves or at their local garage.

Things to Consider Before Purchasing a 125cc Big Bore Kit

1. Compatibility: Not all bikes are compatible with a 125cc big bore kit. Before making any purchase, ensure that your motorcycle’s make and model are listed as compatible by the manufacturer.

2. Legalities: Installing a big bore kit may void your bike’s warranty and may not be legal in some states or countries due to emissions regulations. Be sure to check your local laws before making any modifications.

3. Budget: While these kits are relatively affordable compared to other performance upgrades, they still come at a cost. Make sure you have enough budget set aside for both purchasing and installing the kit.

My Recommended Brands

After trying out different brands myself, I highly recommend two brands for their reliability and quality – Athena and Wiseco. Both have been in the market for many years and have proven results in terms of performance gains.

Final Thoughts

Installing a 125cc big bore kit can significantly enhance your motorcycle’s performance without breaking the bank. However, it is essential to do thorough research before making any purchase and ensure that it is legal in your area. With proper installation and maintenance, you can expect improved power and torque from your bike with this upgrade.
