I bought my fazer thou with 758s already on it, they were black but I wanted blue so I bought new 758 bars.
I put the new bars on and instantly felt a difference, the new bars lightened up the steering.
I measured both bars and found that the new bars were longer.
Do I like the new twitchiness, for want of a better word, no, I preferred the shorter bars.
That 20 mil or so really shows up if you have ridden the bike with both lengths of bar.
Trouble is, I can’t be bothered to cut the new bars down, I just ride the beast as is.
