Aynaxcol CVT Drive Belt 669-18-30 for 49cc–50cc GY6 Scooters — 5-Pack, 18mm Wide 30° Pitch

Aynaxcol 669-18-30 replacement CVT drive belt pack is a set of five aftermarket belts engineered to fit 49cc–50cc GY6 engines for scooters, mopeds, go-karts and small ATVs.

When your scooter or small-engine vehicle needs a dependable belt swap, having an exact-size replacement on hand saves time and gets you back on the road. This five-pack includes five brand-new 669 mm diameter, 18 mm wide, 30° pitch belts designed to match the common GY6 1P39QMB/139QMB CVT configurations used by Roketa, Taotao, Vespa-style models, Jonway and many economy scooters. They are intended as aftermarket replacements—verify belt dimensions against your current part before fitting.

Will these belts fit my 49cc or 50cc GY6 scooter?

These belts are sized specifically for many 49cc–50cc GY6 engines that use the 669-18-30 specification. Fitment depends on the CVT pulley dimensions and belt profile in your vehicle. Check the diameter, width, and pitch of your existing belt to confirm compatibility.

• Diameter: 669 mm — matches many GY6 applications
• Width: 18 mm — standard narrow-profile CVT belt
• Pitch/angle: 30° — fits 30-degree pulley grooves
• Commonly compatible with Roketa, Taotao, Vespa-style, Jonway scooters

How do these belts affect performance and maintenance?

Using the correct belt size helps maintain expected power transfer and CVT operation; worn or incorrect belts cause slipping, reduced acceleration, and premature wear of the variator or clutch. Replacing belts proactively as part of routine maintenance keeps drivetrain efficiency stable and reduces the risk of roadside breakdowns.

• Restores reliable torque transfer to the rear pulley
• Reduces slipping and inconsistent acceleration
• Helps extend variator and clutch component life
• Five-pack format supports multiple vehicles or future replacements

What should I check before installing these replacement belts?

Before installation, inspect the CVT housing and pulley grooves for wear or debris, confirm belt size against the old belt, and check for proper tension and alignment after fitting. If pulleys are heavily scored or bearings are worn, replace those parts to avoid premature belt failure.

• Verify the existing belt reads 669-18-30 or matches those dimensions
• Clean pulley grooves and remove accumulated dirt or grit
• Inspect variator and clutch for wear; replace if necessary
• Follow manufacturer torque and installation steps for safe operation

Why buy a five-pack instead of a single belt?

Purchasing a five-pack offers value and convenience: you have spares on hand, which is useful for fleet owners, workshops, or riders who maintain multiple scooters. Bulk purchases also lower long-term replacement cost and reduce downtime since you won’t need to wait for another order if a second belt is required.

• Cost-effective compared with buying single belts repeatedly
• Ideal for multiple vehicles or routine maintenance stock
• Minimizes downtime with immediate spares available
• Consistent part specification for uniform replacements

Who is this for? The Aynaxcol 5-Pack 669-18-30 belts suit DIY mechanics, small repair shops, and scooter owners who ride 49cc–50cc GY6-based machines and need reliable, correctly sized aftermarket drive belts. If you own a Roketa, Taotao, Jonway, Vespa-style scooter, go-kart, moped or compact ATV that specifies a 669 mm diameter, 18 mm width, 30° pitch belt, this pack gives you multiple replacements for routine maintenance and emergency swaps. Always confirm belt measurements before purchase to ensure compatibility.
