I killed my first 19 tooth front sprocket, chain and rear sprocket, young and silly brought my 850 Commando new when I was 17 years old, all my mates put sh it on me for doing so, so every Friday night and Saturday night burn outs galore at our local hang out, did it for about 3 years until one night I was smoking the rear wheel up then my motor just started revving flat out with no go, looked under my arm to see my rear chain shooting off down the road at high speed, there was about 6 links completely gone.
The front sprocket was fu cked and the rear one wasn't far from it and the chain well it was well stretched and broken badly, well after that night and money replacing the flogged out bits was the last time I ever done a burnout on the Norton then 12 months later I started the conversion to the Featherbed, but mine you I pulled some amazing wheel stand on the Featherbed with the hot 850 and a well balanced bike it stood right up near 90degrees from 1st, 2nd and into 3rd powering on without flipping, (love that race change shift) but only did that a few times as it just takes too much out of sprockets and chains, I am more wiser, well most of the time lol, the wife learned real quick to hang on at certain places.
I just learned not to over stress things and you will have a very reliable bike, hate breaking things from being stupid, but in my youth I had a lot to prove to my mates who said I was crazy buying a new Norton and not a new Honda 750 4.
Well I proved all of them wrong.
By the way when I broke that chain doing that big burn out I waited till midnight when everyone went home to get towed home by my mate on his 500 Honda 4, we still have a laugh about that after all these years lol.
