DID Motorcycle Chains and Transmission Kits – Road, Racing, Enduro & Motocross

DID (D.I.D.) is one of the world's leading manufacturers of motorcycle drive chains, offering high-performance solutions for road bikes, supersport motorcycles, racing, adventure, enduro, motocross and off-road applications.

At Omnia Racing, you can find a wide selection of DID motorcycle chains and DID chain kits in the most popular sizes, including 415, 420, 428, 520, 525 and 530, with solutions designed both as OEM-quality replacements and for riders looking for increased durability, reduced weight and racing performance.

The DID range includes different technologies and performance levels, from chains designed for everyday road use to the DID ER Series racing chains, developed for the demanding requirements of motorcycle competition.

Why Choose a DID Motorcycle Chain?

The drive chain is one of the most important components of a motorcycle's final drive system. It transfers power from the front sprocket to the rear sprocket and is continuously subjected to acceleration, deceleration, high loads, temperature changes, water, dirt and other external contaminants.

For this reason, DID develops motorcycle chains engineered to deliver strength, smooth operation, durability and efficient power transfer.

Choosing a DID motorcycle chain means benefiting from:

• High mechanical strength
• Reduced friction on sealed chain models
• Excellent durability
• Efficient power transmission
• X-Ring technology on selected models
• Specific solutions for road, track and off-road use
• A wide selection of chain sizes and applications
• Chains designed for high-performance and high-powered motorcycles

DID also develops products used in international motorsport, transferring experience gained in racing into its high-performance motorcycle chains.

DID Motorcycle Chain Range: Which One Should You Choose?

The DID Motorcycle Chains catalog includes several product families, each designed for specific motorcycles and riding conditions.

DID VX and VX3 – X-Ring Chains for Road and Adventure Motorcycles

The DID VX / VX3 family is one of the most versatile choices for road motorcycles and a wide range of on-road and off-road applications.

DID X-Ring technology is designed to retain lubrication inside the chain joints while reducing friction, helping to improve both durability and smooth operation.

DID VX3 chains are particularly suitable for riders looking to upgrade their original motorcycle chain with a high-quality solution for naked bikes, sport bikes, touring motorcycles and adventure bikes.

Depending on the specific motorcycle application, the DID range includes 428, 520, 525 and 530 versions.

DID ZVM-X and ZVM-X2 – Chains for High-Performance Motorcycles

DID ZVM-X and ZVM-X2 chains are designed for motorcycles with high torque and power output.

This family uses DID X-Ring technology and is engineered to provide high resistance to chain elongation under load while delivering efficient power transfer.

They are particularly suitable for:

• Superbikes and supersport motorcycles
• Hyper Naked bikes
• Sport Touring motorcycles
• Maxi Adventure bikes
• High-displacement and high-torque motorcycles

Depending on the application, the range includes versions such as DID 520 ZVM-X, 525 ZVM-X2 and 530 ZVM-X2.

DID ER Series – High-Performance Racing Chains

For riders looking for maximum performance, DID offers the ER – Exclusive Racing Series, developed for racing and competition applications.

DID racing chains are engineered to combine high strength, low weight, reduced friction and responsive power transmission.

DID 520 ERV7 – Racing Chain for Road and Track Performance

The DID 520 ERV7 is one of the flagship racing chains in the current DID range.

It is a high-performance 520 X-Ring chain developed for demanding racing applications and designed for riders who require an advanced final drive solution.

The DID 520 ERV7 is ideal for riders looking for:

• Racing performance
• Low weight
• High strength
• Smooth power transmission
• X-Ring technology
• Sport and competition use

It is an excellent solution for track-focused motorcycles and riders looking for a final drive system designed around performance.

DID ERVT, ERT3 and ERS3

The DID racing family also includes models such as ERVT, ERT3 and ERS3, developed for different motorcycles and competitive applications.

The correct racing chain should always be selected according to the motorcycle model, engine performance, intended use, chain pitch and manufacturer's specifications.

DID Motocross, Enduro and Off-Road Chains

DID also offers dedicated chains for motocross, enduro, cross-country and off-road motorcycles.

Depending on the application, the range includes product families such as:

• DID MX
• DID NZ / NZ3
• DID DZ2
• DID ER Series
• DID ATV2

These chains are designed for the demanding conditions typical of off-road riding, where mud, dust, jumps, impacts and constant load variations require reliable and resistant components.

The DID 520 MX, for example, is designed for motocross applications, while other DID chain families provide solutions for enduro, off-road riding and competition.

DID 520, 525 and 530 Chains: What's the Difference?

Among the most commonly used motorcycle chain sizes are DID 520, DID 525 and DID 530.

The correct chain size depends on the final drive specifications of the motorcycle.

DID 520 – Widely used on sport, racing, enduro and motocross motorcycles, with many configurations also focused on reducing final drive weight.

DID 525 – Commonly fitted to road bikes, naked motorcycles, sport bikes, touring and adventure motorcycles, providing an excellent balance between weight, strength and durability.

DID 530 – Typically used on larger and more powerful motorcycles where high strength and the ability to withstand substantial loads are required.

Always select a chain pitch, length and specification compatible with your motorcycle.

DID Chain Kits with Chain, Front Sprocket and Rear Sprocket

In addition to individual chains, Omnia Racing offers DID motorcycle chain kits for a wide variety of motorcycle models.

A complete motorcycle final drive kit typically allows you to replace:

• DID chain
• Front sprocket
• Rear sprocket

Replacing worn final drive components together helps ensure the correct interaction between the new chain and sprockets while maximizing the performance and service life of the transmission.

Solutions are available both for replacing the original motorcycle final drive and for riders looking for a more performance-oriented setup.

DID 520 Racing Chain Kits

For sport motorcycles and racing applications, DID 520 chain kit configurations are available for riders looking to optimize the final drive system.

A 520 conversion is frequently used in performance applications to reduce final drive weight compared with larger chain configurations. However, compatibility, motorcycle power and intended use must always be carefully considered before changing the original chain pitch.

Combining a DID Racing chain with dedicated front and rear sprockets makes it possible to create a final drive setup focused on sporty riding and track performance.

DID X-Ring Technology: How Does It Work?

One of the key technologies used in many DID chains is the X-Ring sealing system.

The special shape of the seal creates multiple contact points and helps retain lubricant inside the chain joints while reducing friction.

The result is a motorcycle chain designed to provide:

• Long service life
• Reduced friction
• Smooth operation
• Protection of internal lubrication
• Consistent performance over time

DID X-Ring technology is used across several road and racing chain families, including VX3, ZVM-X, ZVM-X2 and ERV7.

DID Chains for Honda, Yamaha, Kawasaki, Suzuki, Ducati, BMW, KTM and More

DID motorcycle chains and chain kits are available for a huge range of motorcycles from the world's leading manufacturers, including:

Honda, Yamaha, Kawasaki, Suzuki, Ducati, BMW Motorrad, KTM, Husqvarna, Aprilia, Triumph, MV Agusta, Harley-Davidson, GasGas and many more.

To find the correct DID chain for your motorcycle, always check the exact model, year, engine size, original chain pitch and required number of links.

DID Road or Racing Chain: Which One Should You Buy?

Choosing the right DID chain depends primarily on your motorcycle and riding style.

For road and touring use, a DID VX/VX3 chain can provide an excellent balance between durability and performance.

For high-powered and high-torque motorcycles, the DID ZVM-X/ZVM-X2 family provides characteristics specifically designed for demanding loads and powerful engines.

For track and racing applications, the DID ER range, including products such as the 520 ERV7, provides a performance-focused solution.

For motocross and enduro, choose a DID chain specifically developed for the demanding conditions of off-road riding.
