Watch out for the stock chain.

That appears to have been a catastrophic failure. Derailed it huh. Any idea what caused it? I've only ever seen this happen on dirt bikes and stunt bikes. That's gnarly and terrible just a whole ton of damage there that sucks. Wonder if a rock or debris hopped up there somehow?

Welcome to the forum.
There is a quality chain already fitted to the FTR. The chain stretch the first 350 miles was phenomenal and it needed adjusting twice, I had never witnessed such rapid stretch before on any of my bikes. Since then I have not had to adjust it since for several thousand miles and believe yours has been the only solitary FTR case of chain derailment.

The stock chain is a good DID 525 o-ring chain that almost all modern chain drive bikes use, for it to come off the sprocket like that, it couldnt have been properly adjusted.

Made me go check my chain tension, it was super loose. I had said something when I bought it, they said it was specifications. Measured at only 18mm, so I adjusted it to spec. Hasn't even been 500 miles since I bought it

Yep I actually had it planned since I had my ECU out and it was up in the air. This just gave me a kick in the pants to go do it

Identical scenario to myself. Was really surprised though the amount of stretch on the FTR. On reflection I reckon if I'd backed the bike up with my boot on the chain it would have come off very easily at first adjustment after about a paltry 150 miles, obviously during break in too when it wasn't even being 'gunned' too much.
Really? As stated the chain was of good and proven quality. Wonder what the OP's reasoning behind the derailment may be especially if the chain remained intact? A few more details would have been nice? What sort of road was he on, speed and characteristics of the ride, harsh or just pootling along? 1000 miles? Was this the original chain and sprockets or had they been swapped out already? Something obviously either 'let go' or was amiss? Quite heartbreaking seeing such devastation on a relatively new bike with only 1000 miles on these chain and sprockets. Guess Indian may stump up the repair bill if the OP's statement can be proven?
**Late Edit** I notice the bike has a set of Bridgestones fitted to it. This may have nothing to do with 'new chain stretch' unless of course the chain and sprockets were swapped out 1000 miles ago rather than the bike being new? So thoughts move to what chain was fitted at what mileage and by whom perhaps? There's more to this story that the OP should add to. Welcome to the forum by the way and very interesting first post!

Thank You
this reminds me of the guy on FB the other year saying the steel sprockets and DID chain were trash because his wore out at 5k.. only to learn his chain adjustments and wheel alignments were off the entire time.

That’s not very “ambassador” like. Maybe his chain was defective? Whatever happened, he could’ve been injured. At the very least there are some lessons learned which we may might never hear due to the vitriol.
