Hi Nuthin,
There have been some great suggestions here. The BMWs & Venture are a bit pricey new, but are my first choice in all day/week/month touring. The Honda ST1300 is another option along with Yamaha's STJ(?)1300 - both of which grew up from 1100ccs recently, and would make looking for a used one a great buy. The Yamaha has an electrically adjustable windscreen like the R1150/1200RT. The Royal Star would probably be a good buy also. BMWs hold their value, but around 3 years old, have a big drop in resale price. Then they hold that value forever.
NOW, one that was not mentioned: Trimph ST Executive. They apparently aren't in the lineup now, but they are just like the ST but have an upright seating position. That is the tourer I want, but my bride will not be able to see over my head like she would on a Yamaha VStar 1100. That is important to her. She loves to ride with me, but can't do long trips because the blocked vision bothers her. Rick Mayer told me he should be able to built my saddle to give her enough lift to "look down" at the top of my head.
All these bikes are great and buying them is like purchasing handguns and cameras - "if they feel good in your hand, buy it". Of course in this case, "if it feels good under your bu++, buy it".
Ride 'Em Safe,
Dennis
