Point

・Front spring rates were revised to reduce roll in cornering and improve ride comfort.
・By using L=250 for the front springs, we have taken into consideration not to increase the vibration transmitted through floor that occurs even during daily use.
・Damper adjustment dials for testing: Front 20 click/ Rear 13 click
