If straight-line speed is your priority, the Vitpilen 401 takes the lead. With 35 HP more than the Grom, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Riders with a shorter inseam should lean towards the Grom. Its seat height is 59mm lower than the Vitpilen 401, making it much easier to flat-foot at stoplights and increasing confidence during stops.
