Fits crf, xr50s, and 97' - current xr70, and most Chinese bikes with stock honda style hub. We offer this swing arm in two colors - silver and black.Note: The stock shock will not work with the swing arm setup and a 10.5" inch eye to eye aftermarket / upgraded shock is recommended. Review: Can’t beat it for the money - Had to file the paint off where the brake mounts to the swing arm, other than that the fitment is better than I thought. Not sure if I just got lucky or if the bad reviews are just people who don’t know what they’re doing. Either way I’m satisfied, I definitely recommend it. Review: As described. - Extended the bike just how it said it would in the description. ## Features - 2.5" Extended Crf50 Swingarm - 6061 Aluminum - Lightweight - Available in Black or Silver Finish - Includes brake rod extender, chain tensioners, chain slide & pivot bearings - Also comes with free 120 link chain! - Fits all Honda XR50 and CRF50 / CRF70 Pit Bikes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A1CXU2C | | Best Sellers Rank | #1,772,170 in Automotive ( See Top 100 in Automotive ) #566 in Swing Arm Spools & Sliders | | Brand | 50 Caliber Racing | | Customer Reviews | 4.0 4.0 out of 5 stars (37) | | Date First Available | May 8, 2012 | | Exterior | Black or Silver | | Is Discontinued By Manufacturer | No | | Item Weight | 8 pounds | | Item model number | Swing Arm | | Manufacturer | 50 Caliber Racing | | Manufacturer Part Number | Varies | | Model | Swing Arm | | Product Dimensions | 18 x 12 x 12 inches | ## Images ![50 Caliber Racing 2.5" Extended Swing Arm Fits CRF50 XR50 XR70 Models (Black) - Image 1](https://m.media-amazon.com/images/I/411itv6I+YL.jpg) ![50 Caliber Racing 2.5" Extended Swing Arm Fits CRF50 XR50 XR70 Models (Black) - Image 2](https://m.media-amazon.com/images/I/41h3iETotnL.jpg) ![50 Caliber Racing 2.5" Extended Swing Arm Fits CRF50 XR50 XR70 Models (Black) - Image 3](https://m.media-amazon.com/images/I/413U57OLTWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Can’t beat it for the money *by S***Y on April 20, 2023* Had to file the paint off where the brake mounts to the swing arm, other than that the fitment is better than I thought.

Product was ... *by A***G on April 10, 2018* Wanted to use on an 2003 XR70. Product was not "plug and play", nor even close to it as described. Stock suspension bolt was not long enough, axel bolt was not long enough, chain guard bolts did not fit, spockets did not line up, and brake line (even with extender) did not line up. It also changed the geometrics of the stock swingarm dimensions, contradictory to the product description. Very disappointing to spend all that time trying to put on. Also broke the brake line trying to force the issue... So on top of returning and wasting my time, I needed to buy replacement parts. And to top it off, the company charged me a restocking fee. --- ## 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.co.th/products/21166479-50-caliber-racing-2-5-extended-swing-arm-fits-crf50](https://www.desertcart.co.th/products/21166479-50-caliber-racing-2-5-extended-swing-arm-fits-crf50) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
