Dint'nt see any for Arrow so I thought I'd post..
Model of bike: 2007 S4R
Make/Model of damper: Arrow Competition
Why you chose this damper: Quality, reputation and price. Mostly for track use, noticed a little high acceleration/speed head vibration. Plus helps settle the chassis from down shifting and turn-in setup. Lowered triple a little to improve turn-in, hopefully helps settle that out too.
Ease/difficulty of mounting: Easy, Easy, Easy 20 min. Only problem is you got to dissconnect it to lift the tank, did'nt see that coming
Plus had to tweak the steering stops to prevent hitting the tank. No biggie..
Other mods you have that could affect mounting (e.g. handlebars, triple clamp, etc.): lowered triple ~10mm.
Type of riding you do (street / track): both
Comments on performance: WOW! a huge difference. Smooths things out tremendously even at minimum setting. Hav'nt taken it to the track yet.
