Good cheap replacement. ### ⭐⭐⭐⭐ Great value and exact match *by A***R on April 15, 2026* Exact match for my Wolf Islander 50cc scooter with broken clutch spring - back wheel wouldn't turn by hand and wouldn't hold idle. Having an impact wrench made it easy and made sense to replace all parts. Only draw back is wish it came with cover gasket, ordered separately from different supplier, it looked the same but wasn't . ## Frequently Bought Together - Clutch Set Fit for GY6 50cc 4-Stroke Engine Scooter ATV Taotao Roketa Sunl Include Clutch Assembly Variator Assembly 669 Belt - 50CC Carburetor 4 Stroke GY6 High Performance 139QMB Carburetor for 49cc 50cc Scooter Moped PD18J Carb Engine, 50 cc Carburetor, 50cc Moped Carburetor + Intake Manifold by LOYPP - Weize YTX7A-BS High Performance - Maintenance Free - Sealed AGM Motorcycle Battery Compatible with Gas Gy6 Scooter Moped 50CC 125CC --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/561848960-gy6-50cc-performance-clutch-kit-fit-for-gy6-50cc-4](https://www.desertcart.tn/products/561848960-gy6-50cc-performance-clutch-kit-fit-for-gy6-50cc-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-24*
