Okay, I love DIY mods, so this gets my attention.
The F800GS is listed as 26 degrees on rake, replacing the 21" with 17" will change the rake to like, maybe 24 degrees are there abouts. Pretty good for a track bike wanne be. The Buell is like 21, Tiger 1050 23.
I hate spending money on a one time deal, so I would most likely just take it to the track stock, keeping in mind we are not going to set any speed records.
Actually the soft suspension if stable makes for more forgiveness on the track up to a point. The front dive helps to plant the front to give maximum braking and stays compressed when turning in.
P.S. Oh, and when I went to the track (actually ridesmart) one of our gals on an F800ST ran like the wind, I had to get close in a turn then outlast her down the next straight till brakes to get by, and my Tiger is FAST! :-)
P.S.S. As for the ABS, not sure what will happen with the wheel change, but I can tell you what will happen on the F650GS (twin) and new 150/60/17 rear tire replacing the stock 140/80/17, ABS will shut off. This tire size is 1.8" smaller Dia.
