I replaced my airbags on my 2006 GW 1800 Motor Trike. I changed out the under sized plastic top and bottom airbags with a more robust metal top and bottom airbags. I also swapped out the plastic fittings and small plastic line for 1/4 pneumatic air line and NPT brass fittings. The difference is enormous especially when Kathy and I are both on it. I currently have 25 pounds in the air system which is too much for just a single rider but is great for the two of us. If you are currently fighting a leaking airbag system it is worth the time, money and effort to correct it as it has made my ride totally different for the best.
