Motorcycle Suspension – Maximum Two-wheel Performance
With the extreme performance of today’s motorcycles, both on-road and off, proper suspension setup is essential. Front and rear springs must be matched and tuned for rider weight, ability, riding style and road/track conditions. Which is why Eibach has applied its legendary talents to making your motorcycle perform-and feel-better than you´d ever dreamed possible.
The first step in dialing in your motorcycle suspension is selecting the proper Eibach Moto Spring (EMS) combination. Whether you are a serious racer or weekend warrior, no other modification can affect the performance of your motorcycle as significantly as a properly tuned suspension. Over the history of Eibach Springs, we have set the industry standards for quality control, consistent performance and advanced suspension engineering-and we apply every bit of that expertise to perfecting our springs for high-performance motorcycles.
For the motocross, off-road or dual-sport rider, Eibach EMS springs can help you carve through turns and fly by your competition by reducing bottoming, providing better feel & feedback, delivering a smoother, more compliant ride and helping your bike hook up better on the throttle.
For the road racer, Eibach EMS springs can help you brake later, get on the gas sooner and increase your lean angle by maintaining cornering clearance and preventing excessive dive under braking. At the same time it can help maintain proper chassis geometry under acceleration, increasing your confidence level at the limit of traction.
And for the street rider, Eibach EMS springs are vital to tailor your machine to your exact weight, riding style and preferred riding conditions, delivering a stable, compliant ride, improving cornering clearance, and reducing dive, squat and bottoming. In many cases, using the proper, stiffer springs, front and rear, actually improves ride quality while it takes handling to the next level of performance.
ERS | Eibach Race Springs
It was in Germany in the 1980’s when Wilfried Eibach engineered the first designs of today’s legendary Eibach Race Springs.We still have saved a “Typenliste”, just one sheet of paper, from the year 1986, which pictures the first 50 ERS part-numbers, all metric, 60 mm ID – inner diameter.Obviously this basic approach was spot-on, as even today these historical part-numbers are part of our complete Eibach Race Spring System though a few differences have to be recognized. The quantity of part-numbers/single components have grown from 50 to over 1,300 while early designs are consistently being improved in line with superior materials and manufacturing technology.
The ERS line has evolved over the years to be the world’s most prominent, comprehensive and superior Race Spring System. Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.
In an instance when an application cannot be covered by the Eibach Race Spring System, then Eibach offers a bespoke design and manufacture service.
Based on decades of experience, Eibach has optimized their products to realize the lowest weight and smallest solid height – therefore increasing the maximum travel, block stability, linearity of the load/deflection graph, sag stability and dynamic durability.
Suspension Tuning with ERS
Every suspension tuning is a compromise! Early in a racer’s career, they are confronted with the challenges of Over- or Understeer.
On one hand, the spring system should be compliant and soft enough to compensate for bumpy roads or tracks. This compliance assures permanent road-contact of wheel and tire and therefore guarantees grip and traction.
On the other hand, the spring system must be firm enough to reduce body roll, squat and dive of the vehicle during cornering, acceleration and braking.
Thus, we offer an endless variety of spring combinations utilizing our ERS System:
- 2 (or even 3) ERS Springs with different rates are stacked, resulting in a progressive spring-system various options are possible in serial hook-up
- 2 or 3 different main springs – one after another
- 1 main spring with a tender spring (a linear or progressive one)
- 2 different main springs plus a tender spring (a linear or progressive one) similar options are available in parallel hook-up
Our ERS System offers the Race Engineer multiple set-up options. This has made Eibach the leading brand in Motorsport springs everywhere around the world.
- Over 1,300 single components – main and tender springs – metric and standard, various auxiliary race suspension accessories, ready and in stock on 5 continents
- Comprehensive Program of single components
- Single Main Springs with highest rate-linearity and lowest rate tolerance
- Progressive Characteristics via set-up of different springs serially – double or even triple spring combinations
- Extreme Low Weights achieved through Super Hi-Ten materials and manufacturing technology
- Smallest Solid heights, maximized spring travels and higher maximum loads
- Spring Surface Stabilization through specialized shot peening
- Every ERS Spring preset to block Block and Sag Resistant Smallest Tolerances and precise plane parallelism of spring ends High Dynamic Durability – under Motorsport conditions High quality corrosion protection by phosphating and epoxy coating
- Springs Printed with part-number (which translates = Length, Inner Diameter, Rate)
