If that is the only bike you'll be riding it won't take long to get used to it.
Comments- If that uses the kick starter for the gear lever like my 250 did, I found that thriugh the rough stuff at
Moorebank the weight of the lever bouncing up and down caused clutch slip, plus if you had your heel pushed up against the shaft it would disengage the gearshift mechanism. If it is that set up I'd modify.
Also I would make a retainer plate to ensure the crankcase seals can't blow out. Mine did and went full song into orbit at 'sorbent hill'
From the look of it it's a factory scrambler model and probably has those mods.
