Hi Olly, I strongly agree with the above zero gurus, the belt should be replaced even if there is one tooth missing or any crack or rock in the belt. When I studied engineering, belts wear evenly due to the amount rotations per minute so if one tooth is damaged/missing, the others are soon to follow.

With my original post though, clay.leihy posted the below:

Order your own parts? (Maybe this'll help Aussies?)

The purchase cost of the belt with shipping comes to $150 AUD which is already $100 cheaper than what I paid but if you purchase other items, it is a lot cheaper as shipping is half the cost.

I'll let you know how the order goes with af1racing but if their purchase experience is anything to go by, it should be very smooth.

🤞

Wonder how long in takes AF1 to order and get the parts before shipping.

You definitely need a new belt.

You might ask the dealer that you order from to see about drop shipping directly to you.
I have ordered parts through Hollywood Electrics and they arrived directly from Zero within a few days.
Makes more sense. Why ship from Manufacturer to dealer then to end user? Waste of time and resources.

Hi odedmaz, I definitely need a new belt soon and if I don't ride a motorbike soon, I'm going to go crazy!

KrazyEd, I will ask AF1 to ship directly from Zero to me. Great idea mate!

I've just had a new belt fitted here in the UK. It cost a total of £220! 65 plus vat for the belt and the rest was for two hours of labour.

My last belt only lasted 11,000 miles. I think I lost a few teeth coming off a kerb under full throttle. The wheel span up and there was a horrible crunching noise when it hit the tarmac. After that, the belt started slipping more and more. I ended up riding Miss Daisy just to get me to work and back before the new belt arrived.

I put the short belt life down to riding off road a few times. I also need to avoid going over potholes and suchlike with the throttle open.  There were a lot of teeth missing by the time it got replaced.

I was shocked at the two hours of labour just to change a belt. Learning on the job, I think.  I didn't quibble though as the dealer lent me a courtesy bike for two months recently...

As far as replacing the sprockets with the 2017 ones, I was told that you could have one of the splined sprockets
machined out by a qualified machine shop, put a key way in it and it should work. I am guessing that the wheel sprocket
should just be a straight swap. As with everything else Zero, keep an eye on Hollywood Electrics for when to purchase.

That is intriguing, and I suppose without a Sevcon 4.5 controller, the torque wouldn't break the design limits of the keyed shaft.

Finally made some time for an update.

I emailed AF1 a few questions about delivery times, if they can have Zero deliver directly and some other questions and the blokes at AF1 were fantastic to deal with. They kept me up to date when parts were received by them and when the parts were shipped to me.

All up it took 33 days from ordering to the package being delivered:
- 19 days from ordering,AF1 receiving parts from Zero and then shipping to Australia)
- 14 days shipping from US to Australia.

I have also installed all the parts on my bike and attached photos below.

In terms of price, it is slightly cheaper to buy from AF1 racing but their service is worth more than the savings from buying locally (from this one purchasing experience anyway).

The total list of parts installed since the bike has been off the road:

- New motor under warranty as the previous one showed signs of internal bearing failure.
- New onboard 1.3kW charger as the last was not charging the battery to 100% (usually 91% SoC)
- Tail tidy
- Givi factory top box (also noticed that the rack has the usual seat bolt mounts, under seat bolts AND a metal frame with rubber boot that sits on the tail plastic! I can send photos if anyone is curious)
- a double fast charger (6.8 kW) from EVtricity which I havn't used as my go to electrician is soaking up the sun in the northern state of Queensland. Lucky bugger
Also will not mount the charger to the bike as this will void the warranty so it will stay at home except when I'm touring in summer and it will live in the top box.

Last thing is a good cleaning and I'll have to plan the next upgrades!

And finally getting back to the reason for my post:

I have installed the belt! And have a spare for the next 40,000km (85,000km on the odometer or odomile for the americans

My first belt failed at 5000km, but I think a mate might have smashed it over speed bumps etc. replacement lasted 35000 kms and just lost a tooth. That's acceptable imho. New one is on, will be interesting to see how long it lasts - I have the smaller front sprocket so I know it's working real hard. Took 46m from start to finish to replace it

There is one name to remember (and phone number) if you are an aussie.

Hollywood Electricts!

I phoned them up, ordered 2 belts paid $346 AUD (I think I posted $334 on another post but that was wrong) and had them on my doorstep in 8 days (was delayed because while I was on the phone a guy walked in and purchased one of the 2 belts in stock, so I had to wait an extra 2 days).

I opted for the $80 USD fast shipping (slower option was $60 USD). My belt had 16 teeth missing (5 in one spot) and I was riding it each day in custom mode set to 0 torque. It was painfully slow to accelerate but that was the whole point, less power. It made it through the 6 days (didn't ride on weekend). 

I was also thinking if I could get a new bigger belt pulley machined to fit the 2015 keyed shaft. Anyway that is 60,000 km away seeing I have 2 new belts now.

The manual says to change the belt at 30,000 km, I had done 30,500 km when I stripped the teeth under full acceleration.

   

[oregonrider89]

I just replaced my belt (2015 SR). I noticed teeth missing at 25,000 miles but it lasted almost another 1,000 miles before 90% of the teeth came off under full acceleration. I still made the 20 miles to home with a very gentle throttle hand.

A replacement belt was in stock at Monarch Powersports in Orem, UT. Total cost, with shipping, was $98 and it arrived in 3 days. I replaced the belt myself and it took about 15 minutes.

I love that motorcycle!

I think that's the trick to liveforphysics' wheelie-capable Zero SR.  He has extra lights mounted at 45 degrees down so he can see when he wheelies down the street in the dark.
