I also have had the exact same problem during the first 1000km I probably got a false neutral about 3 times in 4-5 gear, Mention it to the dealer and just got a blank look, Its had it first service fresh oil and see how it goes from now on shrug could just be tight gears not locating during break in.That is strange , mine have jumped out of gear 3 times in 2500 miles , i initially thought that it was me not pushing the gear in fully but then it did it again , after roughly 1000 miles the problem dissapeared so i was thinking the gearbox is fully broken in , but then last saturday it did it again in 4 gear , it was pulling then it jumped out of gear so the revs vent right up and then it poped back in the gear on its own , never seen this on any of my previous bikes . Dealer does not believe me of course .
I too had this exact same issue recently, and now on 3000 miles but doesn't seem to have caused a problem!I have a new manual with 380 miles and noticed while going down the freeway shifted from fifth to sixth the gear indicator showed a strange horizontal bar. I shifted back to fifth and up to sixth and the display looked fine. Other than that shifting has been super smooth. I did raise my shifter a little bit to better fit my boots.
