I went with GP 2 years ago, and liked the improved handling over stock. Although, last season I seemed to be dragging and scrapping a lot. The reason is I was pushing the bike harder and harder, and getting to be a much better rider in the corners with the improved suspension, but it wasn't stiff enough to handle the corner speeds I NOW can go. And yes I'm hanging off the bike. bottom line is it wasn't working for me. Don't get me wrong. I'm not saying anything bad about GP,they do great work and the bike was great handling and plush. The problem is I've change. I'm riding much harder and faster than I did 2 years ago, so I had to go with stiffer front and rear springs.
This time I went with Traxxion. I just got my forks and Ohlins back from Traxxion, but haven't tried yet. The reason I went with them is because they said right away they thought I needed more spring, which I believe I do. Also they say the factory cartridges are only good for about 100,000 miles, and there AK-20's are good for much more. I already have 60,000 miles and should see 100,000 in 2-3 years. I plan on keeping the bike so for me it's worth it. I could have had GP put stiffer springs in, but I don't think they have the cartridges.
If I was still riding the way I was 2 years ago the first set-up would be fine, but now I almost never ride 2 up and almost always push it hard in the corners. Now I'm willing to give up the plush ride for better handling when pushing hard.
The front spring are now 1.1, and the rear is now 900lbs. They were .95, and 850.
Opinions are like aholes....... you know the rest, so take this with a grain of salt. It's just my opinions. Time will tell.
