To me, the best sounds go that way: 6 cylinders > V4 > Inline-four. But as I can't afford the first two, inline-four are the best. :D No bike at the moment, I've sold my K3 1000 some months ago so it was great to hear that sound.
I wanted to get into riding but I bought a ninja400 for two years and never fell in love with it do you think moving to a 750 would make a difference in actually enjoying riding
Good question. There is more to riding than just the engine size,how it sounds of course and current trend of course. If you love riding then you love riding. I had a 1000cc and went down to a 750cc right now and even loved it just as much if not even more. To answer your question, you will definitely fall in love with the 750 no doubt BUT it all comes to what your goals are. I picked this bike to build it for the track, occasionally on the streets. I still lack a few parts before it’ll be ready for the track.
