Over 50 years of motorcycle chains.

Grand specialist and leader in the industrial sector, Regina is also by tradition, passion, and applied technology a producer of famous and highly renowned motorcycle chains. From the mid 1940s to today, considerable resources and commitment have gone into the creation of increasingly advanced and innovative chains, as part of an enduring quest for two fundamental requisites: maximum functionality and complete, tested safety. And today, every Regina chain, type by type, category by category, provides a commanding response.

Standard
Chains for motorcycles up to 250 cc.
Reinforced

With increased diameter pins, in alloy steel, and thicker sideplates to withstand extreme demands such as those experienced in motocross and enduro racing. Rated for road and off-road bikes up to 350 cc.

Professional
Designed and developed to achieve the highest strength and lowest weight, yet with outstanding wear resistance for demanding applications. Rated for road and off-road bikes up to 500 cc.
OR
O-ring style chains of the latest generation having new and better performing O-ring seals. These chains have sealed in lubrication that offers long life and high strength. O-ring chains are for road and off-road motorcycles up to 900 cc.
ZR
The most innovative, highly advanced, and recent Regina development.
Grand Prix
Designed for racing use in both motocross and road racing. Like their brethren, but to a greater degree, these chains represent the result of the great experience of Regina winning over 230 victories in World Championships in motorcycle competition. Available in 7 different versions, non sealed types and with new Z-44, depending on use, they are perfect for road competitions, enduro and motocross racing.
Professional Rear Drive Kits
The Regina Professional Rear Drive kits consist of a front sprocket, a rear sprocket and the specific Regina chain for various motorcycle applications.

Z44 the future already has its chains.

From round-section O-rings to
X-rings, from Z-rings to Z44:
ceaseless technical evolution offers enormous improvements in performance
and life of elastic lubricant seal rings.

Installing a Regina chain with the patented Z44 system means gaining the following extraordinary advantages:

• The Z-ring flexes when assembled to create a spring effect guaranteeing a lubricant seal that does not reduce (or change) over time.
• The lubricant located between the plates and the lobes of the Z-ring keeps the ring lubricated and increase its life.
• The special Z-ring section guarantees enhanced chain flexibility.
• The conical section of the Z-ring provides accurate positioning on the bushing.

The Z44 chains also offer the following features:
• high carbon steel pins
• solid bushings
• solid rollers
• shot-peened plates and rollers for increased fatigue resistance
• pre-stretching
• gold outer plates

The Z44 are the ideal chains for high performance supersport and off-road motorcycles; for this reason, ZR44 chains are used as original equipment by:
- KTM
- Aprilia (Tuono 1000 and RSV 1000)
- Moto Morini
- Benelli
- Betamotor
- Suzuki (Spanish production motorcycles)

Moreover, ZR44 are the ATV chains of Bombardier.


520 ZRA: the winner chain

520 ZRA chtain is the evolution of 520 ZRH chains: it has a reduced weight to run at highest speed, and lower plates to fit today’s rubbed sprockets, that guarantee a lower
transmission noise.

Using the FEM calculation, it has been possible to optimise the inner plates geometry, obtaining a lower profile to reduce weight and bulk, with the same mechanical performances.

Here following an explaining drawing.

520 ZRA chain uses high alloy steel plates and pins, reinforced rollers and patented Z-ring.

With these features, 520 ZRA is a top performances chain, for the best bikes of the latest generation, like Aprilia Pegaso 650, Yamaha MT-03 and Derbi Mulhancén 659.
520 ZRA chains will be available since 2007, May.
