Why Öhlins?

 


Quality

From innovative product design to the exacting tolerances of their precision engineering, Öhlins achieve the highest possible quality. Whether it’s the frictional efficiency of bearing surfaces and seals or the flow precision required in pressurised damping systems, Öhlins have become the industry benchmark for premium suspension solutions.

 

Racing

Racing provides the best research and development platform on which manufacturers can perfect their product. It is a discipline that constantly demands the best performance from all component manufacturers. Öhlins have been involved in World Championship level competition for over 40 years and the results of their championship-winning technology is now applied to across-the-counter products for everyone.

 

Öhlins Technology

From STX to TTX, CES and DFV, Öhlins advanced suspension technology constantly sets new industry benchmarks. Used by World Championship-winning teams and manufacturers of premium and prestige motorcycles and cars, the brand is synonymous with state-of-the-art solutions.

 
 

 

Front Suspension

 

What is front suspension?

The front suspension on a motorcycle serves two main purposes: 

  1. Contribute to the vehicle's handling and braking.
  2. Provide safety and comfort by keeping the vehicle's rider and passenger comfortably isolated from bumps and vibrations.

 

 

How does it work?

The telescopic fork works by a tube sliding inside another tube (like a telescope). One tube is fixed to the motorcycle’s chassis via the steering assembly, while the other is attached to the front wheel. In this way they allow the front wheel to react to imperfections in the road by sliding the tubes into each other (when riding over a bump) or out of each other (when riding over a hole) therefore isolating the rest of the motorcycle from that motion.

 

 

Inside the tubes are coil springs that offer a controlled resistance to the tubes sliding (compressing) into each other. The speed at which the tubes slide into each other or extend out of each other is further controlled by simultaneously squeezing oil through tiny holes during compression and extension. This is called damping and can be likened to a damper on the rear hatch-back door of an SUV to stop it falling shut as you load the car. The oil flow through the damping system can sometimes be adjusted.

 

Why upgrade your front suspension?

When manufacturers choose a suspension for their new motorcycle they must make a compromise between cost and quality. Normally, the higher the cost of the motorcycle, the higher the quality of the components.

Regardless of cost, most standard suspension systems can be improved upon with finer tolerances of engineering, better quality materials and more options for adjustability that enable you to alter the suspension to suit your weight or the way and places you ride.

Upgrading suspension is the single most effective way to improve the comfort, stability, safety and performance of your motorcycle or scooter.

Rear Suspension

 

What is rear suspension?

The rear suspension on a motorcycle serves two main purposes: 

  1. Contribute to the vehicle's handling and braking.
  2. Provide safety and comfort by keeping the vehicle's rider and passenger comfortably isolated from bumps and vibrations.

The most common form of rear suspension for a motorcycle or scooter is a swinging arm with single or twin suspension units. On a scooter, the engine itself is sometimes the “swinging arm”.

 

How does it work?

The rear suspension works by having one end of the swinging arm fixed to a pivot on the rear of the motorcycle frame, enabling the other end, which is attached to the rear wheel spindle, to move up or down as the tyre rolls over road imperfections. 

 

 

In order for the rear wheel to move upwards over a bump in the road, the swinging arm must compress the rear suspension unit or shock absorber. In this way it allows the rear wheel to react to imperfections in the road by moving upwards (when riding over a bump) or downwards (when riding over a hole) therefore isolating the rest of the motorcycle from that motion.

Like the front suspension, the rear shock absorber consists of a coil spring that offers a controlled resistance to the swinging arm moving upwards. The speed at which the coil spring compresses or extends is further controlled by simultaneously squeezing oil through tiny holes during these movements. This is called damping and can be likened to a damper on the rear hatch-back door of an SUV to stop it falling shut as you load the car. The oil flow through the damping system can sometimes be adjusted.

 

Why upgrade your rear suspension?

When manufacturers choose a suspension for their new motorcycle they must make a compromise between cost and quality. Normally, the higher the cost of the motorcycle, the higher the quality of the components.

Regardless of cost, most standard suspension systems can be improved upon with finer tolerances of engineering, better quality materials and more options for adjustability that enable you to alter the suspension to suit your weight or the way and places you ride.

Steering Dampers

 

What are they?

A steering damper is a damping device designed to prevent undesirable and uncontrolled movements or oscillations of a motorcycle’s steering system, sometimes referred to as a “wobble” or “tank-slapper”. 

 

How do they work?

On an Öhlins telescopic type steering damper, a piston (A) is fixed on shaft (B) and pushes damping fluid (blue arrows) through a separate parallel passage (C) into the cylinder.

The intention is to “damp” the movement of the steering as you turn the handlebars from lock-to-lock. As Öhlins steering dampers have adjustable levels of damping by turning a simple knob through a number of very defined clicks, the steering feeling can be changed from “light” to “heavy”.

 

Why do I need one?

Steering “wobbles” on motorcycles can be caused by a number of factors. Sport bikes with steep steering head angles can easily become unstable on bumpy roads while street and touring bikes can even be effected by carrying a passenger or from the weight or detrimental aerodynamics of luggage. Even if your motorcycle has a steering damper fitted as standard equipment the chances are you can improve it even further by fitting a high quality Öhlins damper.

Öhlins Care

 

 

Care 

Regular inspection and preventive maintenance will ensure that your Öhlins products continue to deliver high performance with excellent reliability. For optimal road-user care, Öhlins recommend you have your Öhlins suspension serviced at an authorised Öhlins Service Centre every 30,000 kms or 3 years (whichever comes first). Race users should have their suspension serviced every 20 hours of use.

 

 

Authorised Öhlins Service Centres

Only authorised Öhlins Service Centres have the correct tools and equipment and their personnel the appropriate Öhlins Factory training to execute a professional and effective service on your suspension. Find you nearest authorised Öhlins Service Centre below.
