Extra Volume / The EV Series
is designed for general road riders, featuring adjustable spring preload and an air preload assist system, as well as adjustable extension damping (rebound). By increasing the gas volume
within a limited space, the EV system effectively reduces heat generation during operation, stabilizing oil temperature and damping force to maintain optimal performance.
The EV shock absorber is an entry-level option for general road riders looking to take their vehicle’s stability to the next level.

.Monotube Oil-Gas Separation
: The shock absorber features a monotube oil-gas separation design. The monotube’s excellent heat dissipation effectively lowers the operating temperature of the damping oil, while the large-diameter piston serves as the foundation for a wide-range damping force setting. The
oil-gas separation also protects the damping oil from foaming, ensuring stable damping performance.
.High-Sensitivity, Wide-Range Piston: The high-sensitivity, wide-range piston, combined with a
smooth oil channel design and the diverse torque variations provided by the large piston, ensures the shock absorber delivers the appropriate damping force required to effectively dampen harmonic motion
during operation at low, medium, and high speeds (across a wide range).
.Adjustable Spring Preload + Built-in Gas Preload
: Spring preload can be fine-tuned to meet the rider’s specific needs, while the built-in, precisely calculated high-pressure inert gas assists in maintaining spring preload, offering a wide range of settings and a simplified setup process that saves time.
.Adjustable
extension damping (rebound) with 15 effective extension settings, allowing riders to customize the setup to suit their own riding style.
.Enlarged
Cylinder Chamber: Based on the principles of Boyle’s Law and the ideal gas equation, the original internal chamber volume has been increased within the limited space, preventing the compressed chamber volume from becoming too small and generating excessive heat.
.Length Adjustment: For
certain models, the maximum length adjustment is 5 mm, allowing riders to adjust the vehicle’s height, rake angle, and center of gravity settings.
.12-Month Warranty
: A 12-month warranty is provided for the shock absorber (limited to Taiwan proper).
