it always amuses me that people are so quick to dismiss what a vfr is capable of. especialy in the right hands. now look, an RC51 is definitely a more capable track bike. to say that a vfr is 90% as capable as an RC51 is probably a fair assesment. If you have doubts about this go to one Reg Pridmores schools and see if you can out run him. after all he does teach his classes from the seat of a 94 to 97 style vfr. there must be a reason for that right?

so now to the subject at hand it is my opinion that of the bikes listed the vtr is the best choice of the 3. it's like a vfr, but with a little more thumpity thump. a great all around bike that is probably 90% as capale as an RC51 with a little suspension work just like a vfr. it is also an all day comfortable touring machine with the high build quality and dead nuts reliability inherent in any honda. when a clean example crosses my path I will most definitely snatch it up, and park it right next to my vfr.
to me a Suzi or Kwac are like disposable razors the do their job and do them well. they just have a much more limited lifespan. this is usualy evident in the materials and so forth that they build their bikes with. you can ride around town and see any number of ten or fifteen year old Hondas running around. tell me though when was the last time you went out on your local back roads and saw an early to mid nineties gsxr running around.
