Riding my KTM 690 Duke 2016 towards Brecon from Swansea, after about 25 miles I felt a momentary hesitation form the engine but rode on until riding up hill towards the Crai Resevoir, it stopped altogether and I had to stop. It would not start. With no phone signal I was helped by a passing motorcyclist and police to get the bike across the road and roll it back down to a local pub with a land line and thus a recovery service. Battery ok, fuel and oil ok, no warning lights showing on the display. So it just stopped working with no warning which is not safe- I'm thinking about what could happen in a multi-lane round about for example. Any ideas? As it is, it is un-ridable. Thanks
