Hello, had the bike a couple of weeks, ex demo & the dealer couldn´t shift it. hardly riden though, the tyres as new after a few rides the transmission stuck in 3rd gear, wouldn´t change. had to ride about 20km in 3rd. later was able to get it change gear by flicking the gear lever for about a minute. any ideas about what might have happened and if its likely to stick again. also what about that speedo how reliable is it? this one playing up all the time
