hey guys,
need a lil help in choosing a bike!!!please bear with me!!

ok so am 6'1,and kinda heavily built.....and this is gonna be my first bike after my good ol honda activa.....

i like to cruise on a bike,but once in a while i like to rip the engines,ride fast,take risky turns,risky overtakes,zipping through traffic.....

hence ive finalised quite a lot of bikes....

thunderbird(everyone says looks the best on me,i like it as a touring bike but then i cant zip through traffic which i really like,and am getting it cheap as well through CSD)

p220(in my opinion this bike is last in my priorty,didn like its handling much)

zmr(not yet ridden hence no comments)

fazer(love its handling,accelration is OK)

r15(now this is the baby i love,i havnt ridden it for more than a couple of kms,but the way it slides in between traffic,its accleration,handling is wayy awesome,mileage is allrite as well)

but then people say tall people get back pains while riding r15 for long,it doesn even look good on tall people)

hence im really confused between thunderbird,r15...and if not these then zmr,fazer and p220......

i also loves SBKs,but since i cant afford one right one,i think to myself that a r15 can get me as to a SBK(not in term of performance,but by feel )

but then i also like to cruise,take long rides,comfortably.....

its alll soo damn confusing!!!

please help me!!

thx
VJ
