Heavy duty YSS Shock (FJR's Only).
This Club tested Shock Absorber developed by us and the manufacturer (to get the correct spring rate), is suitable for heavy duty two up touring and/or fast road use.
This opition comes with ride height adjuster. 
Standard spring YSS shock.
A lighter rate spring than the heavy duty spring that's approximately 5% stronger than original. This is suitable for mainly one up use and occasional touring jaunts and is sprung more like the o/e shock absorber but with much better preload and damping and benefits from a progressive spring. It does NOT come with a ride height adjustment facility.
