Go with the color you like or the best deal you can get, I'VE GOT 3 BIKES 650 V STROM , ROCKET thats been tickled and is FAAAST , and a 2015 low rider , ALL THREE have enough power the r3 0-140 is the quickest then the harley then the v strom , ,, 80 -140 same result , but your not talking minuites only seconds behind each other ,, and the 1600 t bird that i used to own would off only just been in front of the harley and not by much , with the r3 always being in front .
But thats based on straight line,look at me, look at me, riding , where it does'nt matter , When i get in the real tight twisty stuff , and want to start giving it **** , guess what , the v strom is the fastest , sure in between bends the r3 , the t bird and the harley have more oomph , but you can hit them bends a lot faster on the v strom .
Don't even think about a measly 100cc both bikes are comparable and its only a twist of the wrist seperating them , An average rider will not be able to take any of these bikes to there limits , i push them bikes to the limit of MY OWN riding talent and its each bike to its own merits ,, Believe me unless your name is Mick Doohan you probably will not be able to push any of them to there limits , so go with the best deal or the color you prefer .
