I am considering an ´03 ST4s. This bike has 8k miles on the clock. up graded tires and a Ducati touring seat. How will this bike work riding 2up? Neither of us is what you would call a large person. After 26 years of not riding, I picked up an s4 monster, not knowing my wife would enjoy going along. While powerful the s4 isn´t quite what you would call a comfy 2up ride. I am a Ducati fan and would appreciate any tips on the ST$s. thanks kw
