I bought a 2018 NC750X bran new last month. It's still in the break-in period, so this may be normal, but during acceleration at around 4500rpms it has jumped out of gear 4 or 5 times over the course of 3 separate rides; usually 5th gear I think. Took it for another couple of short rides since then, and it hasn't happened again. Not sure if the gears are still acclimating or if this is something to get it in to the shop for warrant work. Anybody hear of this kind of thing happening?
