700 miles on bad front bearings

My ninja 500r fork seals have been leaking forever and I finally got them repaired? but they said my front bearings are badass well and I kinda been planning on going on a trip to los angeles from las Vegas? I even used my PTO to get off work but the earliest the bearings Can be replaced is on Tuesday do you think i can make it and then still ride a lot more I already rode the bike it still felt smoother from the fork seal replacement

Plain and simple...
Do you know for a fact the bearings are going bad because you're experiencing noise, wobble, other issues?
Or are you taking the word of a local shop telling you they're going bad?

Not saying shops are dishonest... but I'd want to verify it myself.
Since they had the wheel off to do the fork seals... why didn't they mention the bearings WHILE THEY HAD IT APART instead of telling you after the forks seal job was complete? A simple phone call to you to say hey, "we see your wheel bearings are going bad and need replacing."
If they really are going bad then they should've been replaced while it was apart.

I'd verify they do, in fact, need to be replaced.
If they act or look even the least bit suspicious then YES, replace them... and NO, do not ride 700+ miles on them.

You REALLY don't want to be 150 miles from home in the middle of the desert and one of them lock up on you... you don't want them locking up period but being on a road trip and have it happen is just that much worse.

Honestly, a set of All Balls bearings are cheap... if you even THINK they might be going out... just replace them.
It's a safety thing and worth it.
But it's your a** and your machine... do what you want.

does the front wheel spin freely? I wouldn't ride on it if the front wheel doesn't spin smoothly. if it spins smoothly spray grease on the bearings. I'm still on the stock front bearings at 55k. but I grease them with spray on grease.

OP:

1:Put your bike on its centre stand.

2:With bike on centre stand, loft front wheel a few inches off the ground. Use a piece of wood to bottom of fork tube to keep it there, or if you have somebody to help you have them push down on the passenger grab rail at the back to keep front wheel in air.

3: Spin the wheel. Does it spin straight and true? Does it wobble? Is the motion smooth "like sliding on ball bearings", or rough like a pepper grinder?

4: Holding fork leg with one hand and grabbing the airborne front wheel with the other check for axial or radial play in the bearings (basically, does it move side to side, or up and down?).

Any wobble, or any play, tells you your bearings are done. A set of wheel bearings costs around $20, max, and takes around 30m for the front wheel of you have never done this before. I wouldn't let it stop me from going to vegas.

is it conceivable "they" were referring to the steering head bearings, and not the wheel bearings?

Seems a bit more plausible of bearing failure.
As those usually seem to go out quite a bit sooner than wheel bearings.

So I decided to go anyway? and the bearings were? working? fine but my chain was the part that failed at mile 500 of the trip miles not the bearings so unfortunately due to my stubbornness and faith In this bike I still have to get it towed but when I get it home I WILL BE GETTING IT REPAIRED and OEM they did call me I was just too impatient and sad that I used my PTO to not get to go on my trip because? the parts were not coming in until Tuesday which was my last day of PTO but either way I still had fun
