I just bought my 2015 KTM RC390 last month and it has suddenly developed a strange issue. It will run perfectly fine until I reach the 52-55 mph range then all of the acceleration and engine power drops out until it falls back into the 40 mph range and you can then re-accelerate back up to the 52-55 mph range where it will do it again. I got it past that point then it would accelerate fine. The bike has about 260 miles on it so it shouldn't be having this type of problem this soon. So any information or help on what it might be would be greatly appreciated. I love the bike otherwise.
Called the dealership where I bought it to ask the maintenance department there and hopefully they call me back tomorrow.
Thanks,
Ian
