I understand Busa's come with a steering stabilizer. I have a 2012 ZX-14R and they don't come from the factory with one. Don't know why. When I get on it really hard in 3rd gear at about 110 mph, I get some headshake because the front tire is just skimming the pavement. I ordered a Hyperpro from Motomummy June 2nd and they said it will take about 4-6 weeks. Got an e-mail from them a couple days ago and now they say it will be at least another 4 weeks because they're waiting on installation kits. The Hyperpro is $396 which I thought was a good price and I've seen good reviews on them. Does anyone know of any other good ones that aren't priced crazy (like Brock-Ohlin for over $700 for my bike) and work real good?
