I am looking to lower my 2005 1200GS by 2 inches so my wife will ride and be happy while I ride my brand new 2018 1200 GS Rallye. The 2005 is almost worn out so I want a cheap solution - I heard old RT shocks might do the trick but can not find more about that. Any help is greatly appreciated.
In the immortal words of Rocket J. Squirrel, "but that trick never
works!" Wives do not take well to being given second-hand motorcycles. Or perhaps more accurately, the universe does not take well to giving your wife a hand-me-down bike.
Little story from 30-some years ago: a couple weeks before I got married, I bought one of the very first of the new aluminum Evolution Harley Sportsters. The plan for the honeymoon was that I would ride this new bike, and my bride would ride my two-year-old iron-head Sporty on a big tour up through Michigan, Ontario, New York, Pennsylvania, West Virginia, Ohio and Indiana. After hitting light rain on the first day, she suggested it was a bit unfair that she was hauling all our gear (the Evo was so new it didn't yet have a luggage rack), and I agreed to alternate. Over the next eight days, we had beautiful sunshine every other day, and rain every other day. Naturally, the sunshine was on the days when she was riding the new bike. On the very last day of the trip (my turn to ride the new bike), about 100 miles from home, I saw the clouds stacking up. At the last gas stop, I suggested we switch. Clouds moved out of our path and rained on downtown Chicago instead. When we got home, I handed her the keys and said, "powers greater than mine want this to be your bike."
So be careful... lower that '05, and watch--some fluke of fate will have her riding the new GS...
BTW, lowering an '05 may be harder than it looks--used parts listings at Beemer Boneyard indicate the lowering kit (shocks, side stand, center stand) for '05-early '06 is different from later models and might be very hard to obtain.
