Front Motor mount Collapse
Bought a new front isolator for the FatBab and 3 months later it has completely collapsed. DO NOT buy Harley OEM isolators. Took my old isolator and cut the crown off before re-installing and it is collapsing too. My research yields that the Predator and Sputhe aren't much better and certainly not worth $400.

Your research would be wrong... jus' sayin'... 
Remember, acceleration and braking forces try to push and pull the engine/primary/transmission/rear fork and wheel assembly in the frame through the mounts and engine torque tries to pitch it up and down at the front. The rear shocks exert a constant rearward pull on the engine mounts due to their angle. The HD isolators are poorly engineered but if it did fail this quickly I'd question your vehicle/engine alignment...

I will directly refute the statement against predator. For 1, it is not 400 bux. With today's exchange rate, it is 236 and change delivered to your door. I absolutely love the predator mount. It was night and day difference in stability and vibration reduction on my 2011 Street Bob. I went through 2 OEM mounts, second one collapsed almost immediately after install. Predator is a GREAT improvement.

Order the predator direct from the UK, it is 236 and change. I just looked it up for you.

Sputhe is not an engine mount.....just a stabilizing system...and...keep the oil off your front mount at changes and it will last much much longer

If your engine is not vertical compared to the frame (Jigged off front wheel)
You are going to get transition.
If your wheel is not centered in swing arm you will get that, plus belt wear, plus transition.
If your swing arm is not centered, you have a shet load of problems ...
and most any of these rubber swing arms with over 5 years on them, sitting or not, are just plain shot.
