Had a chance to evaluate the air shock conversion yesterday at a buddy's house, he has an MX track and a creek etc... Awesome. Even the guys that I ride with that are/were skeptical about the P5 were there to see first hand were amazed and how much improvement it made. The track had a series of "Whoops" that would typically hurt in a P5, they were big enough to cause the front shocks to spring bind at speed, but with these shocks I went fast enough to blow my hat off. I am not going to call it "Supple", but it was a huge improvement. FYI I still have the stock rear shocks and no sway bar. As far as articulation its a monster improvement. I can now shove one wheel all the way up until the shock runs out of stroke and keep the other 3 wheels on the ground (with the hoke open). I found a large rock and with two riders we would put one front tire up on the rock with the hoke closed and drive up it till the one rear wheel lifted and we could feel the buggy rock back n forth, but then I opened the HOKE and it settled right down and dropped the lifted tire, so I tried it again with the valve open and had no lift off at all! Passengers were impressed. These are the same guys that would freak out when I would climb hills and have "Aggressive 3 wheel action" so to speak. It looked scary I guess, I never got to see it from the drivers seat.
On the berms and fast corners the thing feels like a rock crawler with a solid axle front end with a pivot point in the middle, the lean was really pronounced but the tires stayed planted. With the HOKE closed the cornering was much tighter and perfect for my riding style since I never go fast anyway. I went faster trying to break things yesterday than I typically ride. The only time I go fast-ish is on gravel roads etc..
My recommendation is to DO IT! a BIG THANKS TO JWB! YOU DA MAN!
