I'm pretty mad right now and I'm expecting a full refund on this as I spent nearly $300 ### ⭐⭐⭐⭐⭐ Great motor for a replacement *by L***R on September 3, 2025* This is a great motor ! It fit my 2020 SSR 125cc Pitbike and will probably be buying another motor once its time to replace it but other than that this motor is perfect for a SSR replacement motor. The only down fall is that it did not come with any instructions on how to wire the harness. But an easy search off YouTube can help you figure that out. ## Frequently Bought Together - CUBELLIN Upgrade 125cc Engine ATV Motor 4-Stroke Single Cylinder Motor Engine Manual Clutch Pit Dirt Bike Parts Complete Kit for Honda XR50 XR70 CRF50 CRF70 & Dirt Pit Bike & Go Kart Motorcycle - YOXUFA 7/8'' Left Clutch Lever Handle Cable for SSR 50cc 70cc 90cc 110cc 125cc 150cc Apollo RFZ DBX18 TaoTao DB17 DB27 Coolster M-125 Baja X-pro Thumpstar Kayo Xmotos Chinese Pit Dirt Bike Parts Black - LAXEEM Wire Harness Wiring Loom CDI Ignition Coil Spark Plug Rebuild Kit for 50cc 70cc 90cc 110cc 125cc Stator CDI Coil ATV Quad Bike Buggy Go Kart --- ## 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/623684283-cubellin-upgrade-125cc-engine-pit-dirt-bike-engine-kit-manual](https://www.desertcart.tn/products/623684283-cubellin-upgrade-125cc-engine-pit-dirt-bike-engine-kit-manual) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
