..... Their mounting points would seem to avoid the need to cut slots in the inner guard, as is required by the Classic towbars. They probably flex up and down slightly more, due to all the curves and bends, but look OK.
I already have a Classic Towbar, but the instructions on where to cut the slots for the hanger brackets are a bit rough. The instruction sheet has some poor images showing excessively long slots, so I am hoping to get a better idea of just where the slots need to be cut, before I hack into the plastic.
The OzSTOC member (JWM) from whom I purchased my Uni-Go tow hitch, put me on to the guy (in Mudgee) he from he purchased the ST1300 (with tow hitch). The Mudgee guy said that he'd had a Classic tow hitch but because of flex and sway he ditched the Classic in preference for the Uni-Go.
I had a Classic hitch on the CB1300, it had flex and sway. The Uni-Go on the ST1300 is much firmer.
Re. the Classic hitch, it was delivered to me faulty (the nut on the left-side upper mounting bracket was welded on to the wrong sdie of the bracket, tightening it may have resulted in it breaking away, rather than tightening against the bracket). Calls and emails (with pics attached) to Steve K. at Classic went for a long time unanswered. When I finally spoke to him, his attitude was dismissive and a request for a replacement ignored.
