Ланац за мотоцикле — Комплетан асортиман ланаца за погон од серије 25 до 530H

Преглед производа

А ланац за мотоцикл is the primary mechanical link between the engine's transmission output and the rear wheel. Every time the engine fires, torque travels through the gearbox, exits at the countershaft sprocket, passes along the roller drive chain, and rotates the rear sprocket to push the bike forward. As one of the most mechanically loaded components in the drivetrain, the chain's condition directly determines how efficiently engine power reaches the road and how long the sprockets at each end remain serviceable.

Motorcycle chains are the most fundamental mechanical component of a motorcycle's drive system. They transfer power from the engine to the rear wheel, and because of that constant mechanical duty, they must be lubricated regularly. Without consistent maintenance, a ланац за мотоцикл use will stretch and weaken — causing the engine to run below its potential and shortening sprocket life at both ends.

Korea Ever-Power Motorcycle Chain Co., Ltd. supplies the full series from compact 25-pitch chains used on small-displacement engines all the way through the 530H fitted on large touring and cruiser machines. The range includes standard non-sealed chains, O-ring variants, X-ring sealed options, and reinforced H-grade specifications — giving every buyer the exact specification their application needs. All chains are produced from heat-treated alloy steel, batch-tested for tensile strength, and dimensionally verified before dispatch.

The table below covers dimensional and mechanical data for the complete ланац за тешке услове рада мотоцикла range. All measurements are in millimetres unless indicated. Break-load figures represent average ultimate tensile strength under controlled test conditions — apply an appropriate safety factor for actual working loads based on engine output and riding conditions.

Keeping the chain clean matters for more than appearance. The dirtier a chain gets, the faster both the chain and the sprocket wear down — grit acts as an abrasive paste between the pin and bushing faces at every joint. Left unchecked, a contaminated chain will elongate far sooner than its design life and transfer that accelerated wear directly to both sprockets.

When a chain wears too long and loosens excessively, it can get trapped between the front sprocket's cover and the sprocket itself, or drop off the rear sprocket entirely and catch on the swingarm. These scenarios are preventable. The front sprocket always wears out first because it is smaller and each tooth engages the chain more frequently per revolution. Once the front sprocket shows wear, it rapidly accelerates wear on the chain and rear sprocket. A worn front sprocket is extremely hard on the chain — and chains are the most costly and critical part of the drivetrain system, so they deserve the most attention.

Choosing the right type of chain used in motorcycles depends on engine displacement, riding environment, and maintenance frequency. Over-specifying adds unnecessary rotating mass; under-specifying shortens service life and increases the risk of failure. The four scenarios below cover the most common applications in the regional market.

Scooters and commuters in the 50–250cc range typically use 420 or 428 standard chains on paved roads under continuous low-load duty. A 428 at 1,900 kgf break load handles this application easily. Fleet operators benefit from consistent batch quality — every machine in a fleet behaves the same way, simplifying maintenance scheduling and parts stocking. On paved urban roads, a standard non-sealed chain cleaned and lubricated every 500 km delivers reliable service at the lowest cost per kilometre.

The 520 series is the most common OEM fit on 250–400cc sport bikes, with 520H or 525H used on higher-output machines in the 400–600cc bracket. At 3,100–3,300 kgf tensile strength, these chains handle the acceleration forces of inline-four and parallel-twin engines without issue. Riders who extend their service intervals or experience mixed road conditions benefit from the sealed O-ring variant in this pitch.

Dirt and trail applications impose shock loads from jumps and fast acceleration on variable surfaces, combined with immersion in mud and water. O-ring sealed 428H or 520H chains are the practical choice — the rubber ring at each pin-bushing joint retains internal grease regardless of what the chain passes through. Standard non-sealed chains in off-road conditions require lubrication after nearly every ride, making sealed variants the more practical long-term choice despite the higher initial cost.

Bikes above 750cc — adventure tourers, large cruisers, and naked bikes — typically leave the factory with 530-series chains as OEM specification. The wider 9.53 mm inner dimension and heavier plate construction handle large parallel-twin and inline-four torque outputs without stress. Our 530H at 3,300 kgf and 1.12 kg/m sits at the top of the standard range; for long-distance touring with minimal stop-for-maintenance, an O-ring 530H is the most practical option.

Selecting a motorcycle drive chain based on price alone is a false economy — a chain that stretches early accelerates sprocket wear at both ends, and sprockets are more expensive to replace than the chain itself. The advantages below reflect what our manufacturing process controls at every stage.

Korea Ever-Power Motorcycle Chain Co., Ltd. sources from the Ever-Power Transmission manufacturing network — a producer operating multiple facilities with over 110,000 square metres of combined plant area, more than 180 registered patents in chain engineering, and a catalogue covering over 2,000 chain varieties across 8,000+ product specifications exported to more than 80 countries. The motorcycle chain range is a focused discipline within this broader manufacturing capability, with dedicated quality controls aligned to the specific dimensional and mechanical standards that define a reliable chain sprocket for motorcycle drivetrain systems.

Sprockets fit our entire ланац за мотоцикл range. The drive chain and the rear wheel are connected through the sprocket system — the uniform distribution of power depends on precise engagement between the sprocket teeth and the chain rollers. Because sprockets significantly impact the chain's service life, replacing the chain and both sprockets together at the end of the drivetrain's service life is the standard industry recommendation.

What type of chain is used in motorcycles, and how do I read the chain number?
Most motorcycles use roller-type drive chains. The number stamped on the outer plate — for example "428" — encodes pitch and width. The first digit represents pitch in eighths of an inch (4 = 1/2 inch = 12.7 mm); the last two digits indicate the roller width family. Confirm this number on your existing chain before ordering a replacement.

What is the difference between standard and H-grade chain?
The H suffix indicates heavier-gauge side plates and a higher rated tensile strength. A 428 breaks at 1,900 kgf; a 428H breaks at 2,300 kgf. Choose H-grade when the engine output is higher, the bike carries regular loads, or you prefer to extend replacement intervals beyond a standard chain's typical service life.

How often should a motorcycle chain be cleaned and lubricated?
Every 400–600 km under normal paved-road conditions. In wet weather, off-road riding, or after washing the bike, lubricate as soon as the chain has dried. Apply lubricant sparingly to the inner roller faces while rotating the rear wheel — excess on the outer plates attracts grit without providing additional protection.

How do I know when a motorcycle chain needs replacing?
Measure 20 full links under slight tension. If the measured length exceeds the nominal 20-link distance by more than 3%, replace the chain. Additional indicators include visible ability to pull the chain away from the rear sprocket to expose more than half a tooth root, or noticeable skipping under hard acceleration.

Can I order without meeting a minimum quantity?
Individual retail orders are accepted with no minimum. Workshop and distributor accounts can access tiered pricing from defined quantities. Contact us with the chain series and quantity required to receive a price.

Do sealed O-ring chains need different maintenance than standard chains?
Sealed chains still need periodic cleaning and external lubrication, but at longer intervals than non-sealed equivalents. Use only O-ring-safe chain cleaners — standard petroleum solvents degrade the NBR rubber seals over time. Apply a wax-based or O-ring-compatible lubricant to the outer roller surfaces; the O-rings handle internal grease retention independently.

Should chain and sprockets be replaced at the same time?
Yes. Worn sprockets have hook-shaped tooth profiles that accelerate wear on a new chain within a few hundred kilometres of use. Replacing chain and both sprockets together at the same service interval is more cost-effective than replacing them individually at different times.

Park Sung-min, Motorcycle Workshop Owner, Daejeon (March 2025)
"We switched our chain supply to Korea Ever-Power about six months ago. The 428H and 520H move fastest in our shop. Dimensional consistency is noticeably better than what we had before — no dead links on arrival, pitch checks out correct every time. Reorder turnaround is fast enough that we can keep stock lean without running out."

Lee Hyun-ji, Daily Commuter, Seoul (January 2025)
"Running a 428 standard on my Honda CB125F for about 10 months now. Fitted it myself — went on without trouble. Still quiet at 8,000 km. I lube it every 500 km and check tension monthly. Good value for a commuting chain."

Choi Dong-hyun, Enduro Rider, Gangwon Province (November 2024)
"Ordered a 520H sealed for my off-road bike. Multiple stream crossings and mud sections over three weekends — no rust on the plates, O-rings still intact on inspection. Standard chains I used before would rust visibly within a week of wet trail use. The sealed variant makes a real difference out here."

Kang Ji-soo, Long-Distance Tourer, Busan (December 2024)
"Fitted a 530H on my CB650R before a nine-day coast route — roughly 2,400 km including two rainy days. Only adjusted the chain once at the midpoint. The service team confirmed link count for my sprocket setup before I ordered, which I appreciated."

Yoon Tae-yang, Courier Fleet Manager, Incheon (February 2025)
"We run 12 delivery bikes on 428 standard chains with a monthly rotation schedule. The volume pricing works out substantially cheaper than buying retail, and quality has been consistent across four consecutive batch orders. Zero returns so far."

Seo Eun-hye, Weekend Rider, Gyeonggi-do (October 2024)
"Not a mechanic, just someone who does her own maintenance on a 125cc scooter. The chain arrived with a clip link included and tension spec markings on the packaging. Managed the install without outside help. Happy with it."

Oh Jae-won, Track Day Rider, Ulsan (January 2025)
"The 525H I ordered for my track bike was properly pre-lubricated and sized accurately. I checked 20 links with callipers before fitting — right on spec. Three track days in and chain stretch is minimal. Price per km is looking favourable compared to premium domestic brands."
