Well I finally step over to the darkside today. Mounted a Kumho ECSTA SPT (KU31)RF on a 2008 GL1800. Went for a quick ride to get a feel for the new ct. A very nice soft ride. It seems to just fall into the turns and very quiet. I look forward to doing a few twisties this coming weekend. I think I'm going to do MT. Hamilton up to the Lick Observatory. I'll post how the ride went when I get back. Where can I get my DS#?
