I have a 2009 Venture GT and looking at a new 2016 Venture TF or a 2015 Venture GT . GT 144" track vs TF 151". What difference will I notice in the track length? I know it might sound strange but I'm a pretty aggressive rider and keep up with most everyone with the big tank. I never bottom out so I wouldn't think the 12.4 vs the 13.8 rear travel would do anything for me.
