It can definitely be fixed. It would be best to have it welded by someone who welds aluminum all the time. Aluminum is more difficult to get right than steel, or so I've been told.
That said, the weld is defective and Honda should pay for it.
If they won't, I'll bet you can find a good welder to repair it for $150 max, probably less.

Hey all I just picked up this used 2015 crf450r, from the original owner, and notice while cleaning the bike it has the exact same crack, thought I would post it up here, seeing as though there is clearly a defect in a line of frames on the 15s i will be contacting my dealer to see if there is any honda support for this issue
That's a duff weld all day.
Honda obviously agreed and fair play to them sorting the situation out for the guy.
Yes, there repairable fix it up with a good tig weld, and back in business, Generally it will crack on either side of a welded repair with aluminum, we use to fix industrial doe mixer spoons for a bakery that's some tough stuff there were $500. a pop lasted only 6 months before it snapped again. never on the repair tho. Depending on how they welded from the factory looks like it was on the stop-start of running into the other weld, seems to be a bit off in an angle, or could be from the heat of the exhaust system as well with stress. Silicone will harden over the years, same as concrete give it 30 years it will turn harder than steel, taking a jackhammer to a milling bed taking concrete off and I hit this old stuff on there never even scratched it lol 😂. Might want to add a small heat shield to the exhaust, just to keep it cooler there, some heat wrap, etc. something to consider in the repair process.
Aluminum is not the same as steel. An aluminum weld should not crack along the side as the weld metal is softer than the parent metal. The weld should crack down the center. With steel if the weld cracks down the center that's a shitty weld.If steel cracks along the side it's usually one of three things...design flaw. wasn't welded right and the heat affected zone is not right from incorrect weld/preheat temps or fatigue.
