I have a gxv120 on a Supa Swift big bob, does quite well. Went through thick wet 1-2ft high weeds on the council side block really easily in august.
Best thing is all it has cost me is a throttle lever, set of blades, air filter, plug, 3 starter screws and 1.2l of oil (2 changes so far)
That being said I intend to add a 2 stroke ute to the collection shortly
