Belt fail after 36 thousand miles
« on: May 06, 2018, 03:15:47 AM »

My 2015 DS belt failed after 36 thousand miles. Luckily I noticed the issue before it snapped. Lot's of missing teeth. It was a bit loose so probably my fault for not checking tension in a while.

Luckily I had a spare belt from my old 2012 DS which works on the 2015.

Sounds about right, I've gone through a belt on my 2016 DSR and carry a spare.

I mean with 57k kilometres you're way beyond the recommended replacement interval, almost double.

I bought a new belt at 20k miles and told the shop to put it on when it came in.
They called me back and said no need, the belts look just alike, shows basically no wear.
Oh and we want $300 to replace it.
So I have a belt in a bag.

A few years ago I bought a replacement belt for my 2014 S.  The price was something like $90.  A couple of days ago I brought a (much wider) replacement belt for my 2018 S and the price was $125.  That is still cheaper than most O-ring chains and much cheaper than the even wider belt for the BMW F800GT, which goes for $450 and can not be brought from any other source other than BMW - not even from the belt manufacturer. 

I might add that O-ring chains typically last anywhere between 15K and 30K miles, depending upon the motorcycle (the fewer cylinders the tougher they are on chains), the riding environment and the maintenance care lavished upon the chain by the rider.

Folks: What about asking Zero to firstly use camshifts instead of belts: lasts much longer as well as safer - less exposed to road (asfalt/dirt) debris and secondly, when solid state batteries are made available drop all need by using two built in wheel engines: one up front and one in the rear. A guy can dream can't he.

I think you mean drivesaft and hub motor? Yes?
A driveshaft has too much parasitic load and I don't think hub motors get us in the vicinity of 60hp. Would be nice if either was a possibility.

My 2017 DSR belt just failed at 18,000 didn’t quite make it to the magic 20K mark.. The replacement was $130 and also $130 for the install.. Seems very fair given the lack of other typical maintenance expenses.

My belt lasted exactly 18,000 miles and started skipping because it has lost enough teeth. However my riding style is opening throttle wide every time opportunity arises and I made a few small jumps over the hills which I'm sure contributed to this. All in all, 18K is what I expected to get from belt anyway.

I just installed this "emergency belt" which is shown here:


Just to be sure on my trip in Iceland.
A new normal belt I'll have with me as well and now I know the steps to install it.

Uwe

Great work Uwe. Glad you installed it, and hope you won't need it.
Best of luck in your trip, Oded.

Is there a write-up for this somewhere? What I surmise from the photo sequence is:
1. Remove entire backend of bike in a way you never imagined it would disassemble.
2. Put it back together with two belts in place at the same time, but old belt no longer engaged on rear axle sprocket.
3. Pull the slack of the old belt to the side and wrap around your frame and zip tie.
4. Ride and enjoy?

Actually, in order to install the emergency belt, you just have to follow the regular belt installation steps.

All it takes is a small gap between the swingarm and frame, in order to push it in between. After that, just fold it neatly in front of the moror, and tie it once to the frame. No need to take apart the swingarm.

This emergency belt Saved us a couple of times already.

Really?  I'm disappointed in that belt, I figured it would be about 50% more durable.
Did you really peg the throttle on full torque a lot or go off road more often?
