525 motorcycle chain comparison points
The Motomaxsfr 525 motorcycle chain significantly surpasses the common standard chain in the market in terms of overall structural strength. We use a special high-carbon alloy steel substrate and combined with multiple precision heat treatment process, so that the whole drive chain in the continuous high-speed operation and violent pull is still not easy to happen deformation derailment, to provide end users with a very high security. In terms of lubrication retention and anti-wear technology, this product is fully upgraded to a low-impedance X-seal ring. Compared with traditional rubber rings, the cross structure can not only seal the internal high-temperature grease more tightly, but also reduce the rotation resistance between metal parts exponentially, greatly reducing the maintenance frequency of long-term use and improving fuel economy.
Farewell to frequent elongated relaxation
Aiming at the pain point that the chain is easy to stretch and derail after heavy-duty riding, the metal structure is completely locked Motomaxsfr the pre-stretching treatment process, so that the chain remains tight under high load, thus avoiding the trouble of frequent adjustment of users.
Overtake internal wear dead corners
In view of the phenomenon that dust and sediment are easy to invade the chain gap to accelerate wear, Motomaxsfr original multi-contact oil seal is used to block external impurities and continuously provide internal lubrication to ensure smooth transmission under bad road conditions.
Eliminate chain breakage at high speed
In view of the chain breakage crisis easily caused by the rapid acceleration of large displacement locomotives, Motomaxsfr thickening the outer chain plate and strengthening the riveting strength of the pin shaft, the tensile strength exceeds 40 kN, providing absolute safety redundancy.

Such users often take long-distance trips across cities, which require extremely high durability and quiet operation of the transmission system. The strong bearing capacity and excellent sealing technology of this chain can ensure the smooth driving of thousands of kilometers, reducing the sudden failure and cumbersome maintenance during the journey.
Hardcore Off-Road & Field Racer
In the face of mud, sand and other extremely harsh non-paved roads, the rider needs the chain to have a strong resistance to pulling performance. The high-strength thick chain plate design can easily withstand the instantaneous powerful torque when the vehicle flies to the ground, effectively avoiding derailment accidents caused by severe bumps.
Urban large displacement heavy machine commuter
Shuttling through the congested city streets every day, frequent low-speed starting and emergency braking are a severe test to the fatigue resistance of the chain. The chain’s excellent wear resistance effectively reduces the cost of daily commuting components and makes the power connection more silky and smooth.
Performance locomotive refit enthusiasts
Refitting players who are keen on squeezing the horsepower limit of their vehicles need high-performance transmission accessories that can perfectly match the high horsepower output. This chain not only has minimal running resistance, but also ensures that the powerful engine power is completely transmitted to the rear wheels with zero lag and low loss.
Instructions for using 525 motorcycle chain
Measuring and Truncating Old Chains
Use a professional chain cutter to accurately push out and cut off the extra metal chain links according to the actual number of links required by the motorcycle sprocket to ensure that the length of the new transmission chain is fully matched with the vehicle chassis space.
Apply special grease evenly
Before assembling the main chain link, the matching special high viscosity grease must be evenly coated on the surface of the four sealing rings and the pin shaft to ensure that the connection part has excellent self-lubricating and waterproof sealing.
Steady press-in and riveting
Use a chain pressing tool to press the outer chain plate firmly into a safe depth, and then use a special riveting tool to evenly punch the end of the pin shaft into a full mushroom head shape to ensure that the joint is absolutely firm under high-speed operation.
Adjust the reserved vertical displacement
After the initial installation of the chain, turn the rear wheel for inspection, strictly adjust the floating spacing of the chain to between 2 and 3cm, and finally confirm and lock the rear wheel bearing nut to complete the replacement.

FAQ et contact
Bienvenue sur notre page Foire aux questions. Nous avons rassemblé les réponses aux questions les plus courantes que vous pouvez vous poser, dans l'espoir de vous fournir des solutions claires et rapides. Si vous ne trouvez pas l'information dont vous avez besoin ici, n'hésitez pas à contacter notre équipe d'assistance à la clientèle.
What is the core difference between the 525 motorcycle chain and the 520 chain?
Answer: The standard pitch of both is 15.875mm, but the rollers of the 525 chain are significantly wider and the chain plates are thicker. This means that it can withstand greater lateral tension and friction loss than 520, and is more suitable for medium and large displacement or heavy duty travel motorcycles.
What is the maximum applicable displacement of this chain?
Answer: Our high-strength sealed oil seal chain can stably withstand the continuous power output of the engine with a displacement of 1,000 ml, which fully meets the high-load use standards of most high-performance road street trucks and heavy off-road vehicles on the market.
What is better than traditional O-type oil seals?
Answer: X-type oil seal has special multiple contact lips, which is more effective in firmly sealing internal grease and blocking external dust. At the same time, its contact area is small, which can effectively reduce the frictional resistance when the metal is running, and significantly improve the transmission efficiency.
How long does this high-strength motorcycle chain need to be maintained?
Answer: It is usually recommended to clean the appearance of dirt and re-oil every 500 to 800 kilometers. If you often ride in rainy or muddy environments, you must significantly shorten the maintenance cycle to prevent metal parts from rusting and sticking.
Can you directly use the high-pressure water gun of the car wash shop to wash the sediment on the chain?
Answer: Absolutely not. The strong water flow of the high-pressure water gun can easily break through the fragile rubber oil seal directly, resulting in the loss of high-quality grease sealed inside and causing rust and damage to the core pin shaft. It is recommended to use a special chain cleaner with a soft brush for gentle cleaning.
How to accurately determine that the drive chain has reached the point where it needs to be completely replaced?
Answer: When you find that the rear wheel adjuster has been pulled to the scale limit of the rocker arm, or the chain can be easily pulled to the outside at the bite of the rear sprocket and half of the gear teeth are exposed, it means that the metal structure has been severely stretched and lengthened. The whole set must be replaced immediately to prevent danger.
