Back in the 70's ,I rode lots of bikes with right side shift. Mostly brits( Triumphs.BSAs,a Norton 850 ). I took my one and only riding test in 72' on a buddy's HD 350 Sprint. Also rode a few old sporties with right side shift. I haven't in quite a while........have to agree.....its hard to go back and forth between the two.....If you start daydreaming, you will get mixed up!!
