The sidecar on the Henderson is a FLXI Arrow Speedster. I have one fitted to my 1921 Ace, that I bought from Dave Shirk many years ago. It came as a generic sidecar probably to fit an Indian twin. As I found out during the assembly, four cylinder motorcycles have wider sidecar frames due to the width of the Four's chassis. So I cut the rear frame (1.125" solid bar stock) where it mounts to the back of the bike, and extended it 2 inches. Up front, I cut off the leading connection and made a special one to fit only the Ace which has a special bend in it to clear the foot brake pedal (thank you Richard Morris for making me a template). At the rear, it didn't quite mate up right, so I made an offset knuckle to secure the rear sidecar frame to the axle plate of the Ace. The Johnson bar on the FLXI is a laminated spring which bolts to the sidecar main frame with U-bolt clamps.

I did a similar conversion to the former Lou Lichva Ace while Mike James owned it. Lou used to swap his FLXI Observer sidecar between his 1924 Henderson DeLuxe and his 1922 Ace. It made sense later as he had a goofy bent bolt about 10-12 inches long to secure the front of the sidecar frame to the Ace's single downtube (the Henderson had twin downtubes). I rode this Ace several times on the road and it was a perfect handling outfit. Lou knew his sidecars. The Observer was originally sold only to Ace. It was their best sidecar according to Red Wolverton. When Ace went belly up, FLXI was left with their premier sidecar and no motorcycle. So they altered it to fit the Henderson, both long frame and short frame models. Lou's sidecar was one of these as it had two castings on the main frame to place the Johnson bar in one of two places depending on which model Henderson was going to carry the rig.

Pulled over for a photo shoot, riding Henderson's with sidecars does not suck.
