Some what like Mojo said, Ohlins make a good setup. But on alot of bikes, the shock style steering dampners can sometimes stick out the side of the bike and can be damaged in a crash.
$450...that's about normal for any desent dampner/stabalizer!
It just seems everytime I turn around Mojo thinks off the wall thoughts from the norm. Of coarse, I'm just harrasin ya Mojo.
However, you must understand that Scotts sets up their street sportbikes stabalizer on a R1. Don't know why a R1 vs a GSXR but that's what they use. Now your RC-51 definately is going to behave differently than a R1. So I'm sure that had something to do with it. Also, Scotts suggests a maintance routine about every 3 years, depening on milage and abuse. It only costs about $40. Not bad!!!
