Klr 650 doohickey

Is it possible for a 2009 klr650 to reach 56k+ miles and not have the doohickey redone/replaced and it still runs good?

As Savage replied, Yes. Runs 'good' is not the issue here.

The question now is, "how much has the vibration increased"?
It 'creeps in' ever so gradually, that we hardly even notice.
Then, one day, "Bang", it locks-up!
Oh Lordy! Now it could be 10 times more expensive to Repair than it was to Maintain!

I replaced my 1987 doo-hickey at 57,000 miles and change, if I remember correctly. GLAD that I DID!

The Doohicky is part of the mechanism that adjusts the balancer shaft drive chain slack, which should be adjusted each oil change. Or at least once a year.
The balancer shaft has nothing to do with the running of the engine. It just cancels out the vibration created by the engine running. Many single cylinder engines have balancer shafts. Some such as on Hondas are gear driven. Others like the KLR are chain driven and need periodic adjustment.

Periodic balancer chain slack/tension adjustment (merely loosening and then tightening an externally-accessible bolt head) remains sound maintenance.

The doohickey (idler shaft lever) was upgraded with the release of the 2008 model KLR650s. While previous models of this component sometimes failed with catastrophic collateral damage, I'm unaware of any subsequent doohickey component failure, although spring tension issues have surfaced.

All this said: It's not a lead-pipe cinch certainty any KLR650 of any vintage will turn into a pumpkin at midnight if the doohickey is not upgraded. With worldwide production over more than 25 years, how many KLR650s now in operation, percentage-wise, have aftermarket doohickeys? (Rhetorical question.)

An aftermarket doohickey, and particularly a "torsion spring," enhance probabilistic reliability and durability. Whether these upgrades exist as mandatory, essential modifications for all model years remains uncertain, IMHO. I think somewhere (Perhaps "west of Laramie" as in the classic Jordan Playboy automobile advertisement), at least one KLR650 rider exists who never heard of the doohickey, or the Internet, riding along peacefully to the end of his motorcycle's service life; YMMV!

You wouldn't, IMHO!

Generation 2 (2008 and later) KLR650s feature upgraded factory doohickeys, much more robust and durable than previous versions. Know of no latter-day doohickey component failures, although spring tension issues have surfaced.

So, you're at low risk, IMHO. If the doohickey has been replaced, good-o. If not, you're probably not at urgent critical risk status. Regardless, I think you'll have to peek into the innards to determine for sure your doohickey situation.
