[TEV]

New'ish bike with less than 500 miles.  Accelerating up a slight hill to maybe 50Mph in a custom mode that is somewhere between ECO and Sport (71% torque setting).  90 degrees hot day in Ohio. No rain, no rocks, no slippage. Snapped right off.  I pushed it a mile to somewhere safe.

I called a friend to get it towed to my house.  Does anyone know if this is a warranty part when less than a year old?

Had you checked your belt tension?  My 2016 FXS was delivered with the belt so tight it was off the scale on my gauge.  Not being experienced with belts, I thought I was using the gauge wrong.  The belt literally did not budge no matter how hard I pressed it.  I imagine my belt may have snapped of I hadn't loosened it significantly to get it in spec.  Like others said it's worth a shot to ask for a replacement.  Sometimes Zero stonewalls, sometimes they're above and beyond amazing.

I believe that in a case of low mileage  broken belt that was replaced for free by the dealer,  was the dealer who went above and beyond taking the loss to make it right to the customer. Otherwise I don't see why Zero wouldn't replace all of them.

Hi, new member here.  I bought a new 2020 FXS earlier this year and its belt had snapped on a test ride before I visited the dealer, they replaced it before I rode it.  There must have been a batch of bad belts.  Gave me pause but I bought the bike anyway.  A few hundred miles now and the belt is OK, I hope the one they put on was from a different batch.

If you get a chance, see if the dealer will say anything about that.  Is it systemic of the 2020 models?

Oh, and welcome!

  There must have been a batch of bad belts.

Perhaps, but I have assumed they were either put on too tight or not aligned correctly when they snap while still fairly new.

Just replacing the belt means it has to be aligned and tension set again, which means the replaced belt could last a lot longer if put on correctly the 2nd time.

I heard somewhere that the new belts can get tighter after a few miles, won't always go looser. Perhaps they put something in the belt that helps them not get loose as miles are added, but perhaps is overdone a bit.   So if it's on too tight when installed, it's likely to break.

I keep my Zero belts just a bit on the loose side of spec and I have more than 10,000 miles  (16.1 KM)  on each with no belt problems, so far.

My dealer just called and said they fixed my FXS so I'll pick it up later. 

I asked them to test the belt tension and set it in the middle.

I got it back.  The tension seems high on my iPhone app but fairly close on the mechanical one.  We'll see what happens!
