Way more torque, yes.

I suspect that early snapping not caused by actual debris is due to alignment of the belt changing, or tension changing, shortly after installation. We may never know...

Electric bike may have a lot of torque at the motor but I'm pretty sure there are belt drive gas bikes out there that put more torque to the wheel in 1st gear without snapping them.

You mean like my thousand pound  Harley (listed below)? But that belt is VERY thick compared tp a Zero belt.

Oggi ho chiesto al concessionario, se fosse arrivata, la cinghia ordinata a luglio, mi ha risposto  che non le consegnano e che 4 moto sono ferme per la cinghia rotta, assurdo!! Io devo centellinare la mia visto che ha percorso 45000km .  Ma non è possibile acquistarla direttamente in fabbrica. ?

Ciao italia,

puoi acquistare la nuova belt e altri pezzi qui' in USA, tramite questo concessionario; la Zero non vende direttamente al pubblico!
Controlla il modello

Grazie Giacomo, sito molto interessante, domani da computer  eseguo l ordine, ho visto che av magazzini ne hanno 8 pezzi, e già che ci sono acquistò, anche il calibro per tarare la tensione della cinghia. . Domani mi danno risposta sulla situazione della moto.

ok cinghia ordinata   ed anche   il misuratore  tensione cinghia.  grazie ,  ancora , Giacomo , per  l'indirizzo  dello store , quando passo da te ti pago una  birra,

cinghia  e kit taraturaarrivati,  prezzo   tra  trasporto e tasse come  in  italia ,dal concessionario, ma  almeno  ce lo qui in casa .  per ammortizzare la  spesa  del trasporto 47€ occorrerebbe  mettersi d'accordo  in  2 o 3 persone .

Ovviamente IPA, qui' a San Diego si trovano solo quelle ... .

Io avevo una SR '15 ... sigh ... modificata tutta LED, parabrezza e bauletto, costruito un caricatore da 6,6KW ... poi due bimbi ... niente piu' moto elettrica ... per un po'!

Per la cinghia, qua' ad un certo punto si trovava una cinghia di gomma che poteva essere usata in situazioni di emergenza, nel caso si rompesse quella vera! La facevi passare dalla ruota di dietro, ovviamente smontata, e la potevi legare in modo che prendesse pochissimo spazio.

Ho visto che ci sono anche cinghie che sono aperte e possono essere riattaccate, sempre per emergenza, ma non sono piu' nel giro e non so' dove le potresti trovare.

Io comunque una extra cinghia la terrei sempre anche solo in casa, non si sa' mai .....

Se non lo conosci gia', questo e' un bel sito per varie informazioni sulle zero: https://zeromanual.com/wiki/Main_Page

Tu  pensa che chi ha acquistato la Gates, è un mio cliente qui di Varèse, ma dal loro sito non è possibile acquistare questa cinghia perché non è a catalogo.  È Incredibile.

To me, this sounds like a manufacturer defect.  My 2020 SR/F belt broke at 54 miles.  Yes, the day I bought it!  Luckily, I was less than a mile from home.  I got it replaced under warranty, and have over 8k on the replacement belt now with no further trouble.  I bought a spare replacement belt, just in case.

I would recommend to try a new belt before going to chain drive.  When it doesn't fail, it's sure far more pleasant than a chain!

My guess would be the shop that put the bike together didn't know how to correctly align and adjust  the belt.  Perhaps they installed it too tight.


I have ~14,000 miles / 22,500KM  on each of my Zero belts.

Belt Anecdote #234:

The other day I took my bike to Davant Bikes in Torquay to have a pair of Michelins fitted. The reason I rode it 70 miles to Torquay instead of 10 miles to my usual tyre guy was I figured I wanted someone who's seen Zeros before fiddle with the belt, largely due to stuff in this thread.

When I went to get back on the bike on its nice new tyres I noticed the belt was literally hanging off of the side of the sprocket by 2mm! Rotating the wheel showed it moving in and out on the sprocket.

So I duly summoned the mechanic and made him fix it. Eventually he got it so that when the wheel was rotated the belt remained perfectly in place with a 1mm gap from the sprocket edge, as it should be. It turned out that their mechanic hadn't ever actually changed a tyre on a Zero before. If I'd facepalmed any harder I would have a brain injury.

Rode it home and all seems well, though I've not checked the belt tension yet (I run mine at 55kg).

Surely changing a tyre wouldn't require any adjustment of the belt? You can leave the adjusters where they are, pop out the spindle, change the tyre, and put the spindle back. (At least you can on most bikes with chains - I'll have to go double-check my SR/F now.) It might be a little snug getting the spindle back in, but not too tricky.

I have no idea what he actually did in the workshop coz I wasn't watching

You would think by now that belt drives would be all figured out.   I recall I had a belt drive on a 2000 Buell X1 Lightning I owned.   Never any discussion about it. 

The 2017 FXS that I bought about 6 months ago from a woman in Sarasota has over 12,000 miles on its original belt.  And she stored the bike outside all the time.   When I got it and bought a belt tension gauge, I found the belt to be on the high side of the tension range too.   I loosened it up a bit and the bike seems a bit more quiet now.   Although yesterday I was reviewing an owners manual and it says a loose belt gives less range.   I do wonder though if the belt is very tight, isn't it also putting more stress on the motor shaft bearings?   

As for changing a tire with a belt drive, I think I would reduce the belt tension prior to removing the axle.  You might be able to get by without doing it but it would probably be a big struggle getting the axle back in place.   Of course if you don't own a belt tension gauge then you are probably not going to have the proper tension when you put the wheel back on the bike.
