Polyurethane Motor Mounts for Dyna
#41
I don't work for them but I have them. Just getting the word out that there are other options and solutions to inferior stock mounts.

Here's my mount soaking up a lot of vibrations.

Are they? IMO the original glide pro is not much better than new stock bushing in a bagger.. They don't control lateral forces.. Put an indicator on the swingarm pivot shaft and use a pry bar between the swingarm and the frame.. The force to deflect the swingarm is less with glide-pro.. Anyway the issues to fix the bagger frames is more complex than the dyna..
In the case of the dyna, making a mount that uses solid urethane seems like it would produce excessive vibrations while minimally controlling side forces.. I know that Ore likes to experiment with casting different durometer urethanes to try and come up with something that works but IMO using elastics to control side forces doesn't work. Better to use an incompressible, low coefficient of friction, high tensile strength plastic to control side forces then use a urethane to control forces in the vertical plane..

Well.. Not sure the "damping" characteristics of the polyurethane would be all that good for bagger swagger since the frequency of the swagger is so low compared to something like engine vibrations.. Since it seems to work reasonable for motor mountings, I suspect it depends on the formulation. Both glide-pro and compcams make front mounts from polyurethane. I you look in the web, you'll find it used as a vibration isolator.. What would be better.. A spring? Might make the bike handle like a pogo stick... :-)

Poly is used in aftermarket systems only. No OEM uses it as an engine mount. Thats because of its inherent drawbacks.
