I can feel your pain. For better term "exciting" the bike has to "feel special". If not, then I will hate it after few months. Yes, Italians feel special, but are expensive gamble.
Japanese lack attention to fine detail, just compare looks of swingarm of S1000RR with ZX10R, one is beautiful and other is ugly in my opinion.
How 95% people buy cars: outside look.
If I had to buy street sportbike today then it would be 2015 S1000RR or 2013 HP4, I'm not crazy about looks, but it feels somewhat "special" (unlike japanse bikes).
Comparing to other manufacturers BMW made substantional changes for S1000RR every 2-3 years and 2015 is certanly up to date and is amazing on both street and track.
For me: Busa yesterday, BMW today, Gen6 tomorrow (hopefully).
P.S. For track my practical choice is Gen5 if my Gen4 blows up next season.
Gen4 race: high spec.
Suzuki GSX1300R Hayabusa 2013: stock.
Kawasaki KX450F 2016: love it.
