Since the introduction of the new chassis in late 2014 I have yet to have a report of a single chassis failing for any reason whatsoever. You'll have to try very hard to break it. Please don't.
If you wear the chassis out, and I'm still selling counters, I'll give you a new one. You will be asked how many miles it took to wear it out.
If the counter breaks, and I'm still in business, I'll work with you on getting your wheels under you again. How hard I'll work will depend if it was the result of abuse, age, speeding etc. I'll wing it, it doesn't happen very often.
