Recently I took on a group project with 3 greats; Charlie Watts, Doug Hoboult, and TC Hoboult. The plan is to straighten an old sporster hardtail frame. If the aligning goes well we will add a few design enhancements. Then Doug and TC will finish the build out and TC will pilot this classic to Sturgis and back! (next year)
Here’s the frame, engine, rearwheel, and forks mounted on the aligning frame.
In the garage ‘frame airbag deflated’ sitting on frame feet. There are 2 separate air bags frame and seat. Each bag has an independent pressure control circuit located right behind the gas tank. The piston tail light points up at an angle when the frame air bag is deflated. The rear fender rotates inward toward the seat when deflating the bag and then rotates outward during inflation, and the tail light beam goes to the horizontal position. The other air bag is multi-purpose it supports the seat. The seat has a compound hinge in the front and the second bag is used to adjust seat ride height, spring constant, and is used to lift the seat away from the rear fender when deflating the frame airbag (that’s the position you see in the photo below). The seat returns to the predetermined ride height and pressure when the frame air bag is re-inflated at ride time!
