The Yamaha YFZ 450 is a popular choice for off-road motorcycles, and one of its parts that can be upgraded for better performance is the 5th gear wheel. The 21T Yamaha 5tg-17251-00-00 5th gear wheel is a common aftermarket upgrade. In this discussion, I will provide the pros and cons of buying this particular product for your Yamaha YFZ 450.

1. Increased Top Speed: The 21T 5th gear wheel provides a taller final drive ratio, which in turn results in a higher top speed. This can be beneficial for riders who frequently ride on open, flat terrain.

2. Improved Power Delivery: A taller final drive ratio can also help improve power delivery, making the bike feel more responsive and powerful, especially during low-speed maneuvers.

3. Enhanced Off-Road Performance: The 21T gear wheel is a popular choice among off-road riders as it allows for better wheel speed during turns, making the bike more agile and nimble.

1. Reduced Low-End Torque: The downside of a taller final drive ratio is that it can reduce low-end torque. This means that the bike may not accelerate as quickly from a standstill or climb steep hills as efficiently.

2. Higher RPMs at Cruising Speed: At cruising speeds, the engine will be spinning at a higher RPM, which can lead to increased engine wear and noise.

3. Not Suitable for All Riding Conditions: The 21T gear wheel may not be suitable for all riding conditions, especially for riders who frequently ride on hilly or technical terrain where low-end torque is essential.

The Yamaha 5tg-17251-00-00 21T 5th gear wheel for the Yamaha YFZ 450 offers several benefits, including increased top speed, improved power delivery, and enhanced off-road performance. However, it also comes with some drawbacks, such as reduced low-end torque, higher RPMs at cruising speed, and not being suitable for all riding conditions. Ultimately, the decision to buy this product depends on your individual riding style and preferences. If you frequently ride on open, flat terrain and prioritize top speed and power delivery, then this gear wheel may be worth considering. However, if you frequently ride on hilly or technical terrain and prioritize low-end torque, then it may be best to stick with the stock gear ratio.

If you are considering upgrading the 5th gear wheel on your Yamaha YFZ 450, I would recommend carefully considering your riding style and preferences before making a decision. Consider factors such as the terrain you ride on, your riding speed, and your power delivery preferences. If you decide that the benefits of a taller final drive ratio outweigh the drawbacks, then the Yamaha 5tg-17251-00-00 21T 5th gear wheel may be a worthwhile investment. However, if you prioritize low-end torque, then it may be best to stick with the stock gear ratio. Ultimately, the choice is yours, and I hope this information helps you make an informed decision.
