1. Glixal ATKS-03905 High Performance Racing Moped ATV Scooter Torque Spring with Clutch Springs for GY6 125cc 150cc 157QMJ 152QMI Engine (1500RPM,Yellow)

When I first came across the Glixal ATKS-03905 High Performance Racing Moped ATV Scooter Torque Spring with Clutch Springs, I was intrigued by its promise to enhance the performance of GY6 125cc, 150cc, 157QMJ, and 152QMI engines. As someone who enjoys tinkering with my scooter and ATV, I understand how crucial the right clutch springs and torque spring can be in optimizing power delivery and overall riding experience. This product stood out because it offers a set of 3 clutch springs combined with 1 torque spring, specifically designed for a balanced and efficient upgrade.
One of the key features I appreciate is the inclusion of the yellow 1.5K rated springs that operate around 1500RPM. From my experience, clutch springs with lower ratings, like 1K, tend to engage sooner, allowing for quicker take-off and higher top speeds, but they often struggle with tasks requiring more torque, such as climbing hills. On the other hand, 2K springs provide stronger grabbing power and perform well in challenging terrains but might compromise top speed due to higher RPM engagement. The 1.5K springs in this set strike a sweet spot between those extremes, offering balanced performance that’s neither too sluggish nor too twitchy. This makes it a great choice for riders who want reliable acceleration without sacrificing the ability to handle inclines smoothly.
Another aspect that caught my attention is the thoughtful design consideration that the manufacturer included multiple springs to cater to different riding styles and conditions. It shows an understanding that performance upgrades can’t be one-size-fits-all and that riders might want to experiment or adjust based on their specific needs. Plus, the yellow color of the torque spring not only looks appealing but can also help riders easily identify the spring rating for future adjustments or replacements.
Of course, I do appreciate the honest note that the exact performance improvements depend on various other factors like engine condition, overall setup, and riding environment. This transparency helps set realistic expectations and prevents any surprises after installation. From my standpoint, this means the Glixal springs are a reliable upgrade that can substantially improve clutch responsiveness and torque delivery when paired with compatible engine tuning.
To give a clearer overview, here’s a simple comparison table that summarizes the clutch spring ratings and their typical performance characteristics

if you’re looking to upgrade your GY6 125cc or 150cc engine’s clutch system with something that offers a solid balance of responsiveness, torque, and hill-climbing capability, I find the Glixal ATKS-03905 set to be a compelling option. It’s thoughtfully designed, includes multiple springs to tailor your experience, and comes with clear performance guidance. While no product can guarantee specific results due to the many variables involved, this clutch spring kit seems well worth considering for anyone serious about enhancing their moped or ATV’s ride quality and reliability. If you want a straightforward, effective upgrade that doesn’t push extremes too far, this could definitely be the choice to make.

2. High Performance Racing Spring for GY6 125cc 150cc 157QMJ 152QMI Engine Moped ATV Scooter Torque Spring with Clutch Springs (1000RPM)

When I first came across the High Performance Racing Spring for GY6 125cc 150cc 157QMJ 152QMI Engine Mopeds, ATVs, and Scooters, I was intrigued by its promise to enhance the overall riding experience. This product specifically targets users like me who own GY6 engine variants and seek to improve torque response and clutch engagement.

This characteristic is especially beneficial for city riders who often stop and go, as it reduces the lag during acceleration. However, the trade-off is that it might be harder to climb steep hills, which is an important consideration depending on your typical riding terrain. For me, living in an urban environment with moderate inclines, this seemed like a reasonable compromise for enhanced responsiveness.
From a build quality standpoint, the product stands out with its use of high strength materials that promise stable performance and longevity. The firm surface coating not only prevents rust and wear but also adds a glossy finish, giving my scooter a subtle aesthetic upgrade. It’s reassuring to know that the springs won’t quickly deteriorate or lose their effectiveness, which is crucial for any performance part that deals with constant mechanical stress.
That said, I appreciate the honest note mentioning that the exact performance gains from these upgrade parts can be influenced by various other factors such as the overall condition of the engine, tuning, and riding style. This transparency helps set realistic expectations and encourages me to consider other complementary modifications or maintenance to maximize benefits.
To give you a clearer picture, here’s a summary of the main features and their potential impact

Given the quality materials and thoughtful design, I find it a worthwhile upgrade that combines both functional and aesthetic benefits, making it a compelling choice for anyone looking to enhance their GY6 engine-powered ride.

Buying Guide for Clutch Main Spring for GY6 150Cc
Understanding the Role of the Clutch Main Spring
When I first started working on my GY6 150Cc scooter, I realized how crucial the clutch main spring is to the overall performance. This spring controls the pressure applied to the clutch plates, affecting how smoothly the clutch engages and disengages. Knowing its function helped me appreciate why choosing the right spring matters.
Identifying the Correct Specifications
My initial challenge was finding a clutch spring that matched my GY6 150Cc engine. It’s important to check the OEM specifications, including spring tension, length, and wire diameter. Using a spring that is too stiff or too weak can lead to poor clutch performance or premature wear. I always recommend measuring the original spring or consulting the engine manual before purchasing.
Material Quality and Durability
From my experience, the material quality of the clutch spring significantly affects its lifespan. High-quality steel or alloy springs resist fatigue and corrosion better, ensuring consistent clutch pressure over time. I avoid springs that look cheaply made or lack any protective coating, as they tend to wear out quickly.
Choosing the Right Spring Tension
One thing I learned is that spring tension influences how the clutch feels. A stiffer spring can prevent slipping under heavy loads but may make the clutch harder to operate. Conversely, a softer spring eases clutch lever effort but risks slipping if too weak. Balancing these factors based on my riding style was key to finding the right spring.
Compatibility with Aftermarket Clutch Kits
If you plan to upgrade your clutch plates or use aftermarket components, ensure the spring you buy is compatible. I found that some springs are designed specifically for stock setups, while others suit performance kits. Double-checking compatibility saved me from unnecessary adjustments or replacements later.
Price vs. Performance Considerations
When shopping, I noticed a wide range of prices. While it’s tempting to go for the cheapest option, I focus on springs that offer good durability and reliable performance. Investing a bit more upfront often means fewer replacements and smoother riding in the long run.
Installation Tips Based on My Experience
Installing the clutch main spring requires some care. I always make sure to compress the spring evenly and avoid forcing it into place to prevent damage. If you’re not confident, seeking help or watching tutorial videos can make the process smoother and avoid common mistakes.
Final Thoughts
Choosing the right clutch main spring for my GY6 150Cc made a noticeable difference in ride quality and clutch longevity. By focusing on correct specifications, material quality, and compatibility, I ensured a reliable clutch system that suits my riding needs. Take your time to research and select wisely, and your scooter will thank you.
