Significant improvement vs my old shocks, these things are legit. ### ⭐⭐⭐⭐⭐ Has transformed my Monkeybike NO INSTRUCTIONS *by M***. on 13 July 2023* Very well packaged, good quality, the yellow springs match my bike perfectly. The difference from the standard Honda units was noticeable when I first sat on it. The bike now rides like it should have done when Honda made it. HOWEVER no setting up instructions, there are 3 adjustments & no guidelines! Just stating they should be inspected by a qualified mechanic is just ludicrous. Any one buying from Amazon is not going to pay a mechanic!! ### ⭐⭐⭐⭐⭐ 2019 Honda Monkey Install & Ride Improvement = Good *by G***. on 23 July 2019* No issues installing the shocks on a 2019 Monkey. After riding the Monkey for 16 miles on paved roads, the difference was significantly better versus the OEM shocks which would typically bottom out on me. Comparing the two shocks, the coiled spring was thicker, along with being adjustable on either end, besides having a hydraulic reservoir system that has a dial to adjust. My Honda Monkey is yellow so the shocks I got matched the bike perfectly, only difference I noticed is that it does not have chrome end parts that the OEM shocks had, but because the hydraulic reservoir is also a yellow like color, it gave a positive look/appearance of the Monkey (IMHO). ## Frequently Bought Together - FXCNC Racing 320mm 12.59’’ Motorcycle Rear Shock Absorber Suspension Sensa-Trac Load for ATV Go Kart Quad Dirt Sport Bikes (Monkey Bike Z125 2018-2020)(320mm-340mm) - Muc-Off All-Weather Motorcycle Chain Lube, 400ml - Motorbike Chain Lubricant, Chain Wax for All Conditions - Motorcycle Chain Oil for On and Off-Road - K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Honda, Kawasaki, Triumph, Yamaha Motorcycles, KN-204-1 --- ## 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.us/products/523376709-racing-320mm-12-59-motorcycle-rear-shock-absorber-suspension-sensa](https://www.desertcart.us/products/523376709-racing-320mm-12-59-motorcycle-rear-shock-absorber-suspension-sensa) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-26*
