In the motorcycle world, European bikes from KTM, BMW, or Ducati are typically considered to be the most fun. While they cost a shit ton and require very frequent maintenance, if you ride a KTM or a BMW it shows that you are willing to throw a stupid amount of money to have the most horsepower and the best handling even though you may break down on the side of the road and need to change your oil every 500 miles.
I don't intend to shit on Japanese motorcycles because they (Honda, Yamaha, Kawasaki, Suzuki) do a great job of providing a reliable (and still very fun) motorcycle experience but hop on a BMW or a KTM and you'll understand how it's just better as long as you can stomach the cost and maintenance.

I will never judge someone's choice of motorcycle (unless it's too fucking loud) but the most fun you can have on two wheels is when the bike comes from Europe.
