I got this because I needed it to arrive quicker. It is cool looking, but I don't know what the point of the aluminum is if it's not lighter than the steel. ### ⭐⭐⭐⭐ Good the bad and the ugly... *by M***L on Reviewed in the United States on January 28, 2020* It'll most likely wear faster than most expensive brands but not bad for what it is... ### ⭐⭐⭐⭐⭐ Fits 2020 KTM 500 EXC-F *by J***. on Reviewed in the United States on February 13, 2020* I purchased this for my 2020 KTM 500 EXC-F even though the listing hadn't been updated to reflect it fitting the 2020 model.As shown in the pictures it fits perfect.I cant speak for the longevity of the sprocket as I just installed it but it seems like a quality piece. --- ## 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.vn/products/145159230-42t-teeth-rear-chain-sprocket-for-exc-exc-f-exe](https://www.desertcart.vn/products/145159230-42t-teeth-rear-chain-sprocket-for-exc-exc-f-exe) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-22*
