Point
To achieve upgrade the ride comfort of GRMN, we have been designing, doing actual test driving and redesigning again many times.
Only the wide diameter of the single tube could bring a fine balance with the calm driving comfort for city or highway driving without too much softer feeling.
We worked hard for improving the drive feeling to make it milder than stock specifications. You can also enjoy more connected feeling and precisely control a vehicle. In addition, only FR could enjoy the corner speed feeling controlling by acceleration and load movement to the limit.
As a result, this balanced softness keeps high stability even on the bad road surface.
You will find satisfaction in comfortable daily driving fast speed, winding roads and circuit driving.
The standard position of the damping force adjustment dial is set to the 15th click position.
We recommend the spring rate setting F-2K/R-1K for the customer who prefers the ride comfort to sport drive feeling. Although handling becomes a little milder, vehicle suspension stability and feedback are unchanged and enjoyable to drive.
● Required modification
Requires the hole drilling in the trunk for damping force adjustment cable.
If the spring or other parts touch the rear inner fender, cut it to adjust.
