I'm kinda trying to stay away from adventure bikes. Doesn't appeal to me, and I'd like to pass it later as well.Well, considering your height an ADV bike will definitely "fit" you!
I'd prefer to get something minimalistic.
I wouldn’t overthink a 4cyl vs. a twin, they both will go far too fast far too easily if you’re not careful.
Thing is, the 650 is docile until you rev it past say 7k, it’s about what you think is comfortable and what you like.
I’d personally suggest a 400 or so, especially if you plan to pass it down.
Yeah, I figured out that 400-500 would be a good starting point. I can learn faster and pass it to my wife.
Now considering KTM390 and Husquarna Vitpilen401. Basically same bike, husquarna got a newer design.
