i recently purchased a 2011 rt with 30,000 on the clock, i wanted a bigger bike for more comfortable touring, i previously rode a f700gs, my question is, when accelerating 1st, 2nd, 3rd, 4th the rear end 'kicks out' a bit, is this normal also under braking and down the gears the bikes rear end kicks again, is this normal, im asking as i remember having a vespa where theswingarm bushing was failing and the results were similar, or is it just me going from chain driven to shaft driven? ive put the bike on center stand and there is virtually no movement in rear wheel.
