Note that it took an insane amount of modifications to make it work for my CT90 but I think it's worth it. ### ⭐⭐⭐⭐⭐ Quality *by C***E on November 19, 2024* Thanks very much it arrived like days early so delivery was very fast, this was the best engine I could think of to use for my style of build so thanks a lot for having this option as an option that was available. I went with this engine because of the centrifugal clutch being automatic but still having four manual gears as a manual, plus I can add a radiator and stuff, a lot of four strokes have less than 4krpm so that means weak torque and this one has 7.5k which is stronger, it's pricey but it will be greater and more reliable than the common two and four strokes. ## Frequently Bought Together - Lifan 125cc Engine Semi-Auto 4 Stroke Motor for Trail Bike CT70 90 110 125 Dirt Bike Trike Four Wheeler - PZ20 Carburetor for Kazuma Baja 50cc 70cc 90cc 110cc 125cc TaoTao 110B NST SunL 4 Stroke ATV 4 Wheeler Go Kart Dirt Bike Honda XR70R XL75 CRF80F XR80 - Mighty Max Battery YTX4L-BS - 12 Volt 3 AH, 50 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery --- ## 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.is/products/224912973-lifan-125cc-engine-semi-auto-4-stroke-motor-for-trail](https://www.desertcart.is/products/224912973-lifan-125cc-engine-semi-auto-4-stroke-motor-for-trail) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-05-29*
