Vortex Racing & EK Chain Buying Guide
Buying a new chain for your bike can feel daunting. With so many chain models and potential uses, it can be hard to know which one is right for your setup. This guide covers the basics so you can make a more confident choice.
Chain Pitch
Chain pitch refers to the spacing between links and the overall size of the chain. For example, a 530 chain is thicker than a 520. In most cases, sticking with your bike’s OEM pitch is the right move. Riders looking to reduce rotating weight sometimes convert to a smaller pitch, such as going from 525 to 520, which can make the bike feel more responsive. When changing pitch, the chain and both sprockets must all match.
Sealed vs. Unsealed
One of the first decisions is whether you need a sealed or unsealed chain. Sealed chains use O-rings or X-rings to retain lubrication and keep contamination out, which makes them a strong choice for street use and longer service life. Unsealed chains require more maintenance, but they are often preferred in motocross and dirt applications because they are easier to clean and have less rolling resistance.
Seal Types
O-ring chains are common, cost-effective, and offer solid durability. X-ring chains are a step up, with better lubricant retention, lower drag, and longer life. For riders who want better performance and longevity, X-ring chains are usually the better option.
Master Link Style
All chains use a master link for installation. Clip-style links are common in race applications where chains are removed and cleaned often, but they are generally not recommended for street use. Rivet-style links are the standard for everyday riding and road racing because they are more secure. Screw-type links are another option for riders who want a rivet-style installation without specialty tools.
Chain Length
Chain length can change when gearing changes. A larger sprocket may require additional links to maintain proper fitment. Most road bikes use fewer than 120 links, and chains can be shortened if needed, but a chain that is too short cannot be lengthened without adding links, which is generally not ideal for a fresh installation.
3D vs. Stamped Chains
Stamped chains are the standard option and the right fit for most riders. EK’s 3D chains use forged and machined plates to reduce weight and increase strength. These are intended for riders who want the highest level of performance, including race use. Hybrid options are also available for riders looking for a balance of performance, durability, and appearance.
Maintenance
Proper maintenance is critical to chain life. Dirt bikes with unsealed chains should be cleaned after every ride. Street bikes should generally have the chain cleaned and lubricated every 300 to 600 miles. Tension should be checked regularly, and chains with stiff links, rust, or excessive stretch should be replaced.
Common Use Cases
Different riding styles call for different chain choices. Dirt bikes typically benefit from unsealed chains, while street riders usually want a sealed chain for longer life and lower maintenance. Performance street riders, road racers, and stretched-bike applications may benefit from higher-end chain options depending on power level and intended use.
