Feel free to pass this on to your wife, from another wife...
Dear, making your husband sell his 800GS and buy a road oriented 800 must be one of the silliest things you have done in your life, for a number of reasons:
1. He would be safer on the 800GS than the road oriented 800 on any road surface, and also in traffic, since the higher and upright seating position allows him to see further ahead.
2. He would be safer on these out of the way back roads than on any type of road in traffic any day, even if he rides solo in desolated places.
3. Making a husband (or wife for that matter) do something he or she does not want to do will lead to much sadness later in life, and this is the most dangerous of my three comments to you, since this is the one which ends marriages.
Lastly, we all ride, my husband, our daughter and I, and believe me, we are all concerned about the other's safety when we are riding, it sort of makes sense since we care for each other. BUT, also since we care for each other, we allow each other room to live our lives, and some people "live" in different ways than others. So please get over this, and go and tell your husband to sell the road oriented piece of crap and get himself a DS bike again - you can thank me later.
