Just replaced the air bags on my Motortrike, What a difference. Wife is extremely happy and you know what they say about Happy Wife. I ordered the ones from http://www.airbagit.com/product-p/baga-800-long.htm, Got them in three days but when I got them installed they would not air up. The threaded nipple on one bag was cracked, Called airbagit and explained the situation and they sent me another bag, no questions asked. Very happy with customer service. Im running 30# with two up with the shocks set on lowest setting, Rode 200 mi. Sun. and felt great, Lot more cushion in the ride. Still experimenting with setting for one up but very pleased with the upgrade.
