Stabilizer
John
My 96 FLHTCI is my first big bike, and in reality my first bike. I had a Honda Magna, but only had it for half a season and logged less than 3k miles on her. I've had my wonderful Evo for a year and a half with almost 10k happy miles.
Can someone describe what the stabilizer does? Due to my lack of experience I'm not sure what some of the comments about cornering and wobble are, I might be experiencing them but just don't know any better. I would also love to see a picture of where they go if anyone can do that easily.
All touring Harleys since the 1980s have a rubber-mounted engine. The swingarm and rear wheel are mounted off the back wall of the transmission casing and the trans is bolted to the engine. That large assembly, roughly half the weight of the bike, is held in the frame by rubber mounts - one at the front of the crankcase and two at the rear. There is a third mounting point between the cylinder heads. The system is triangulated, which is good, but there is a missing vital link.
There is one stabilizer link providing lateral support to the front rubber, in full view when you look at your bike. It allows the engine to wobble up and down, but not move sideways. A second stabilizer in between the heads allows similar movement and provides lateral support up there.
The rear rubber mounts are at each end of the swingarm axle, hidden from view by the passenger footrest mounts. That axle holds the swingarm on the back of the trans and is isolated from the frame by the rubber mounts.
Unfortunately there is no third lateral support for those mounts, which is where the infamous bagger wobble originates. Sideways input from the rear wheel, such as while cornering, puts loads into those rear rubbers and creates slight lateral movement. Not good!
There are around a dozen brands of handling stabilizer, of which the True-Track is original and, IMHO, best. It provides that critical lateral support for the rear mounts and transforms the way the bike steers and corners.
Hope that helps! If not ask questions!
