Would you mind posting some thoughts on comparing the FX to the 500 EXC? I've wondered how they compare.
The 500 EXC was my all-around commute bike and dirt bike from 2013-16. It was awesome with 180 mile range, mini luggage rack for multi-day dual sport rides, heated grips, etc. It was definitely not for highway use and I eventually blew a valve and warped the head on a trip in Death Valley. Amazingly, I had that repaired for less than $800. But it seems to run loud and eventually will blow up again. 11,500 miles on it now.
Since the Zero came along, the EXC has been reserved for dirt and long dual sport rides. I stopped swapping the dirt/street wheels on it, and just leave it in dirt mode. It runs pretty loud so I fear the engine could blow again and strand me. It does yield much better torque in 1st and 2nd than the FX, so it wheelies way better.
I have no worry taking the Zero on the freeway for a few miles at a time. Its primarily for urban street duty so I don't want to hassle with dirt chain/wheel conversion, and I don't want to get it banged up. The short range makes it useless on the dirt, but it's awesome and utilitarian around town with the top case.
Now whenever I get on the EXC, the noise and vibration seem really unrefined and irritating at first. Barring any major component failure with the FX, its total cost of ownership is far less. But I still gotta have both!
