Review: Worth the Money - They are tubes and do tube things, no issues! ## Features - UNIVERSAL FIT 2.25/2.50-16” OFF-ROAD MOTORCYCLE INNER TUBES - These inner tubes fit motorcycle tires with an inner diameter (rim diameter) of 16 inches, an outer diameter of 21 inches, and widths that are between 2.25 inches to 2.50 inches. It has the same dimensions and specifications as the 70/90-16, 80/80-16, 80/90-16, and 90/80-16 motorcycle tires, and 2.50-16 dirt bike tubes. - COMPATIBLE REPLACEMENT INNER TUBES FOR DIRT BIKES, PIT BIKES, AND OFF-ROAD MOTORCYCLE - Several brands and models that are compatible with this size of inner tubes include Honda CRF 80F (front tire), Honda XR 80/XR 80R (front tire), and most motorcycles with standard tires. - TR4 STRAIGHT VALVE STEM FOR HIGH TORQUE APPLICATIONS - Centered with a straight and round stem, the TR4 valve fits most rims with a round valve base. Designed specifically for relatively low psi motorcycle and ATV/UTV tires. As they are secured to the rim with nuts and washers, there is a lesser risk of the valve disappearing down to the rim when pumping air. - ENJOY OPTIMUM RIDING COMFORT - Made from natural rubber and butyl blend, these inner tubes have a superior impact and vibration dampening property. And as they are also thicker than average inner tubes in the market, the dampening effect doubles, enabling the inner tubes to work effectively in tandem with the bike’s suspension system to provide you with the most comfortable ride. - IMPORTANT NOTE: This replacement kit is an aftermarket product produced by CalPalmy (TM).

I recently got my hands on a set of 2.50/2.75-17” motorcycle inner tubes, and let me tell you, they've been a fantastic addition to my ride. These inner tubes fit perfectly in my dirt bike and offer a smooth riding experience I've been longing for. One of the things I appreciate most about these tubes is their compatibility. They fit a wide range of bikes, from my trusty Honda dirt bike to my friend's Coolster. We were both pleasantly surprised by how versatile they are. If you’re unsure about the fit, just check your tire's sidewall. It’s a universal fit for most 17-inch rims, and having that flexibility is a huge plus. I’ve even used them as a substitute for some smaller tubes, and they worked like a charm. What really sets these tubes apart is the quality of the ride. Made from premium butyl rubber, they provide excellent impact absorption and puncture resistance. This means fewer worries about unexpected flats when you're out enjoying your ride. I’ve taken my bike on some pretty rough trails, and these inner tubes have held up beautifully. The ride feels noticeably smoother, and I’m not constantly concerned about hitting a rock or bump. Lastly, I have to mention the peace of mind that comes with knowing there’s a helpful customer service team ready to assist if needed. Although I haven’t had to reach out yet, it’s comforting to know they’re there. Overall, these inner tubes have made my rides more enjoyable and stress-free. Whether you're riding for fun or as a commuter, having these reliable inner tubes can make all the difference! ## Frequently Bought Together - (2 Pack) AR-PRO 2.25/2.50-16” Off-road Motorcycle Inner Tubes with TR4 Valve Stem - 70/90-16 Motorcycle Tire Replacement Inner Tubes - Compatible with Dirt Bikes, Pit Bikes, and Off-road Motorcycles - IRC T10334 Mini-Cross Motorcross Front Tire - 2.50-16 - IRC Mini-Cross Motocross Rear Tire 3.60-14 TT 43P --- ## 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.pt/products/166190540-2-pack-ar-pro-2-25-2-50-16-off](https://www.desertcart.pt/products/166190540-2-pack-ar-pro-2-25-2-50-16-off) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
