I upgraded the rear shocks on my 2009 G5 to Hagons, and they make a tremendous difference in terms of ride comfort and handling. I actually contacted Hagon directly, having gone through their USA distributor's web page at which I learned that they are no longer a domestic distributor. I went through several rounds of emails and even a couple of phone calls to make sure that I could make the best combination of what I wanted and what would work. Touch base with them about your weight, bike model, riding style and characteristics, and what you want in a shock, and they will customize them for you within their parameters and get them to you in a hurry. This is the best comfort/handling mod that I have made to my bike so far. Their customer service and communications are superb. The quality is top-notch, and obvious as soon as you handle one.
