Snapped chain

Hi,

On the way back from the Le Mans motogp last month, about 30 miles from the ferry port, the chain on my '07 Tuono Factory snapped. Luckily only doing about 70, heard a bang, pulled the clutch in and coasted to a stop. Called the breakdown insurance (RAC, great service) and was taken to the ferry and the following morning home. Thought it was just bad luck, a one off, until another (ex) Tuono owner, same bike, same year, told me has the same problem. He had his 'bike from new and had not ridden far; mine was second hand but had only done 12K miles at the time. Has anyone else had the same problem? Plus, the chain scrubbed off some of the blue paint on the rear wheel. Anyone know what the colour is?
 
Just buy a Tsubaki heavy duty chain as a replacement mate....They will last and give you peace of mind.
 
A chain will only last as long as it's looked after,it could have been run dry a couple of times by a previous owner or poorly adjusted etc,like any mechanical components they need a bit of TLC,it is 8 years old too :thumbup
 
always pays to keep a good check on the chain and sprocket condition and TBH 12,000 miles is what most chains are guaranteed for
was checking mine on the SMT the other day and found this

needless to say it will not be fitted with a cheap RS fekin chain
 
Iris aren't a bad make,that could have took a road chipping or something through it
 
Bloody hell Brooksy, that was a good find! Doesn't look like it would have gone far
 
looks like its caused a mis aligment as well, i had one snap @90 nearly took my leg off ripped my leathers, smashed the cover, all this happend in fast lane!

looks dry as well!
 
good spot then, dont think many ppl even pay attention to chains as they should!

Very fortunate find Brooksy:thumbup

At least with a Scottoiler my chains clean enough to check anytime (even if the back wheel ain't so clean... at least it's painted black ;) ). But must remember to do so soon!

Mite be worth checking which did chain that is. ...
I've just bought the 525 VX GB one and Tbh the jury is out on it.
1st ride was 20m home from the shop and it had stretched more than a whores knicker elastic.
2nd ride was 100m and it had to be adjusted again.
3rd ride was 260m and it's not far off needing adjusting again.
Hopefully it's settled down now but doesn't inspire confidence.
Normally you buy a chain, adj it once then doesn't need anything other than a clean n lube for miles n miles.

Kicking myself really... wish I'd bought the ultra HD DID ZVMX instead - if only for piece of mind.

Not trying to put anyone off it BTW. .. just "not sure" about it myself !

Most chains stretch a bit over the first few thousand miles.
What you've described there is perfectly normal.

You'll need to adjust a for the first few rides, then it should settle in with the required adjustments getting smaller and smaller.
 
Hope so T... hopefully off to jockland next week n if the weather plays ball twill be around 1,400m trip.... best take me torque wrench !

When you look at the two side plates that are visible in the picture, it appears that one is upside down. This in itself is not an issue, but I would assume that the plate on the damaged link was the joint in the chain, and I suspect that it was too tight from the minute it was fitted.
This chain was always going to fail, you have been a very lucky lad in my opinion.
MOT'd, I seriously suspect no more than a tyre kicking MOT.I hope you're going to kick some *** over this, you could have been seriously injured, if the chain had suffered a catastrophic failure.
