Well I tried it and it is better then I expected. I put a General G Max 195/60/16on the rear of my R3T today and I am I'm impressed. It is replacing an Avon Cobra with a slight flat spot in the center, still had a good amount of rubber left. The General handles better then the slightly worn Avon. The rear brakes work better and overall a softer ride. It take a little more effort in turns but not much, it did not get in trouble when pavement was uneven. I have not experienced it trying to stand up when coming out of a turn. I guess I am sold on the Darkside idea.
As far as the r+r of the rear tire it is one of the easiest to r+r. I used one of my of Harley floor jacks and grabbed the rear frame with the outside part of the jack, then put two straps from the jack to the handlebars. Solid as a rock and no wood or adapters needed as bike sat level. no worrying about the front wheel moving because the straps keep the wheel straight. I will post photos of jack setup when I can.
Now that the tire job is complete I will be mounting Whelen TIR3 lights on the rear to make the bike more visible. This will be much brighter then standard LED's and Signal Dynamics Back Off setup. will have the option of steady burn or flashing with brake. I think I will do the flashing as it will really get the attention of vehicles behind you.
