Unless you have tried many different bikes you wouldn't understand. Every bike is different and there is no one perfect bike. Trying different bikes is fun.
I have and I do.
In the last 12 months I have ridden the K1600GT, R1200GS, new FJR1300, ZZR1400 (1441), a '99 ZZR1100 and a Triumph Tiger Explorer.
On my list for the next 12 months are the new Trophy, new R1200GS, and the Versys 1000.
I am limited to bigger bikes due to my size.
However, I don't have to own the bikes to ride them.
Some are swapped with friends, others were test rides from Dealers.
The only one from that entire list that got me fizzing was the ZZR1400 but after half an hour my wrists were starting to scream "Uncle".
Can I justify $16000 for a toy I can only ride for (admittedly an awe inspiring and exhilarating) 45 mins to 1 hour.
No.
