Best 420 Motorcycle Chain
When selecting a chain for your motorcycle, consider the chain type, size and length.
- Chain pitch – The first digit represents the distance between pin centers. This is commonly 420, 525, or 630 for most motorcycles.
- Roller width – The second and third digits denote the inner width between the side plates where the rollers sit. Wider chains can handle more power.
The chain roller size is a key factor determining chain life. Larger rollers last longer.
All chains have a tensile strength rating you can reference to match the motorcycle’s power output. Check manufacturer guidelines for recommended engine sizes per chain type.

Renthal R1 420 Works Chain
Specs
Make: Renthal
Model: R1 420 Works Chain
Type: non-O-ring
SUMMARY |
The Renthal R1 420 Works Chain is a premium high strength, non-O-ring off-road chain with excellent impact load resistance and was designed specifically to withstand the stress found in off-road applications. The R1 420 is the perfect choice for anyone searching for a combination of high strength, weight savings and maximum power transfer. |
REVIEW: “This chain, undoubtedly, is the toughest chain out there for off-road motorcycle (like a highly customized, seriously powerful Sur Ron – it can outgun 450s in certain situations [like tight trails and corners – but don’t bet on it for those long straights]). This thing cranks out a boatload of low-end torque and stretches chains like it’s going out of style.
Giving this chain a real workout, it takes it like a champ. Hare Scramble, Enduro, and Trials are my main gigs, relying heavily on regenerative braking for the rear, so this chain is feeling the heat from all directions. I’ve gone through my fair share of high-end 420 chains in no time… that is, until I got my hands on this one. And, unbelievably, this chain hardly shows any signs of stretching. It’s honestly baffling! I’ve never seen a 420 chain hold up this well to the kind of punishment it’s taken.
Keep up the good work, Renthal. It’s a solid 5-star performer. I’m seriously stoked with this one.”
DID 420V Steel Professional V Series O-Ring
Specs
Make: D.I.D
Model: 420V Steel Professional V Series
Type: O-ring
| SUMMARY | The DID 420V Steel Professional V Series O-Ring chain is a high-quality motorcycle chain designed for professional use. It features a durable steel construction with various links, making it suitable for a wide range of motorcycle applications. The inclusion of O-ring seals enhances longevity and reduces maintenance needs. This chain is known for its strength, reliability, and resistance to wear and tear. It’s an excellent choice for riders seeking a dependable and long-lasting chain for their motorcycles. |
REVIEW: “This has made riding my Honda Grom so much more enjoyable, I drip 80 weight gear oil on both of the O-rings of every link wipe clean ride for 600 miles then wipe the chain with a clean rag and add more oil.
Now I never have to adjust or clean my chain, I’m at 13k hard stop and go miles and counting…
**Edit** Chain lasted 21,000 miles, it started to get stiff in spots but I started going 8 hundred to 1000 miles between oiling it, the last time I let it go to 1,600 miles and noticed it was really loose so the o rings are probably compromised, it’s ok because the sprockets are worn out now too so it’s best to replace them all at the same time.”
RK Racing Chain GB420MXZ 420 Series Gold Heavy Duty MX/SX Racing Non O-Ring Chain
Specs
Make: RK Chain
Model: Gold Heavy Duty MX/SX Racing
Type: non-O-ring
| SUMMARY | The Gold Heavy Duty MX/SX Racing Non O-Ring Chain is a high-performance option ideal for motocross and supercross racing. Its lightweight yet durable construction delivers exceptional power transfer, while the gold-plated finish enhances longevity. However, it requires regular maintenance and may not be the best fit for everyday riding or budget-conscious riders. Excellent quality and cost performance for motocross racers 125cc to 250cc. |
REVIEW: “This is a must-have for any high HP mini. I noticed the chain and accessory pack are the same as another household MX motorsports vendor branded chain.
I would highly recommend this chain for anyone regardless of setup. The alternative is to keep tightening and replacing noodled stock style chain. That gets old.”

When Should You Replace The Chain On a Motorcycle?
Check the Chain
Check the Chain: Look at your motorcycle’s chain to see if it needs replacing. If it looks stretched, twisted, or if the links are worn, it’s time for a change.
Stretched:
When we say a chain “looks stretched,” we mean that it has become longer over time due to wear and tear. This can affect its performance and needs replacement.
Twisted:
If the chain is “twisted,” it means that it’s not in a straight line as it should be. Don’t Twist the Chain: If you see your chain is twisted, don’t try to fix it by cutting it. This can lead to malfunctions, making your motorcycle unsafe to ride. When a motorcycle chain becomes twisted or kinked, it means that it has not been properly aligned or maintained. This can occur when the chain is not correctly tensioned, lubricated, or when foreign objects get caught in the chain. A twisted or kinked chain can lead to poor performance, increased wear, and potential safety hazards.
Motorcycle Chain Replacement
Sprocket Replacement: While some mechanics suggest replacing both the chain and the sprocket together, you don’t have to do this too often. It’s usually fine to change the entire drive (chain and sprocket) every second time you replace the chain.
Motorcycle Sprockets Explained
To check the condition of the front sprocket, it’s necessary to remove the protective cover. You can also inspect the teeth by gradually rotating the rear wheel. Worn teeth will look like those in the illustration. If the sprocket is missing teeth, has chips, or bent teeth, it requires immediate replacement. Inspecting the rear sprocket is easier, and the signs of wear are the same as on the front.
When to Replace:
If you’re wondering when to change your chain based on miles or kilometers, aim for around 20,000 kilometers. However, if you’re diligent about your bike’s maintenance, you can push it to 30,000 kilometers between replacements.
We recommend watching the video to understand whether it’s necessary to replace the chain or not:
Maintain Your Chain:
To make your chain last longer, keep it clean, and well-lubricated. Regularly tighten a loose chain to ensure it works properly.
FAQs
Q: What types of chains are used in motorcycles?
A: In most motorcycles, a roller chain is used to transmit torque from the gearbox to the rear wheel. The size and specifications depend on the type and power of the motorcycle, and by construction, chains are divided into two main types: non-O-ring and O-ring.
More precisely, motorcycle chains can be divided into five categories:
- Non-O-ring chains.
- Reinforced non-O-ring chains for powerful motorcycles.
- O-ring chains with regular O-ring seals.
- X-ring chains with X-shaped seals.
- Z-ring chains with Z-shaped seals.
In regular chains, there are no seals – they are lightweight and affordable but wear out faster than O-ring chains, where the lubrication is hermetically sealed in the joint. Heavy-duty reinforced models are more durable and designed for powerful motorcycles. The service life of O-ring chains depends on the shape of the seal – for example, the X-ring lasts longer than the O-ring.
Q: What are the components of a chain?
A: A roller chain consists of five parts:
- Pin
- Bushing
- Roller
- Inner plate
- Outer plate
In O-ring chains, various types of seals (O-Ring, X-Ring, Z-Ring) are also used, and special links with locking plates, pins, or rollers are used to connect the chain.
Q: What is the difference between Z-Ring and X-Ring chains?
A: The difference lies in the shape of the seal cross-section. It is considered that Z-Ring is an ‘advanced’ version of X-Ring, which lasts longer and retains lubrication even better.
