Myself, having a short inseam, I have no choice but to one foot it on a LOT of bikes I've owned and or ridden. This means for my Kymco Super 8 150 too.
If I could get both feet down, I would use both. More especially for uneven surfaces. Therefore, at times, I need to plan my stop(s). I would want to plant my foot on which ever is on the high side of a slope or plain. Although, that doesn't always happen, as I seem to instinctively always plant my left foot first. I still struggle planting my right as it does not feel natural, or in other words, second nature.
