4-strokes are quieter and smokeless compared to 2 strokes.
But are there any technological improvements/new models on the horizon that will make eg a Robin 35 even quieter, as it's still quite noisy and attracts attention, and to raise its power from 1.6 to 2.0/2.2hp?
Or is it not technically feasible at this time?
