Replace...
...and get one for the rear with a 90' bend valve stem, installed brakeside. (easy air checks)...

Once a tube has been inflated for a period of time,.. it loses elasticity...
It doesn't deflate back to it's original size...
This makes it much more likely to seat badly in a new tire...

I reused them as a kid, in dirt bikes,... but, in a street bike, that may take you 100's of miles in a day,... I wouldn't trust an old stretched out tube in a new tire...

Ludicrous Speed !... ... Huh

Probably still rubber instead of PVC. Save it. It might be okay, put a new tube in, toss the old one in a No direct sunlight Spot. Check it out, have it around. As noted, may not be able to reinstall, but if it's real rubber, DTM..

I would recommend you buy a new tube.
