I started on a kawa er6n, 650cc parallel twin.Will do a quick research on KTM 390...thank you.
The power was very linear so it was very controllable and was great for city driving.
Just unfortunate I had an accident on it 2 months back, came off at 70km/h but my foot got trapped by the gear lever and scrapped my foot and toes to the near bone. And my knee had a hole the size of a R5 coin, obviously landed on a stone of some sort.
My advice to you, get the bike. Just don't skimp on good gear. I had decent gear that saved my elbows and shoulders but my shoes were crap and I paid the price.
