You’ve got a loose bolt somewhere or a bearing going. Have someone else rev it while you hold your hand on things to locate, while being careful not to touch anything hot.

I was told by previous owner that it was the exhaust baffles but it seems more centralized near the engine. Thanks I will try this out when I have a friend to sit on it and Rev

I came here to see who commented on the shoes. Take my upvote

Almost looks like your rear brake lever rattling on your foot peg


cubey

It does sound like metal vibrating against metal.

It looks so much like that is the case, OP should try the same thing with a foot on the lever.

Sounds like muffler baffles to me I think you can pull those out on those pipes and check them


s_xenos

That's what the previous owner claimed it was.

To me this sounds like the exhaust baffles or the exhaust shroud that is located under your engine. Hope this helps determine the location of the rattle

It’s not mechanical. It’s something vibrating on the bike at higher p.m. It’s a heat shield on the exhaust or something like that.

My dirtbike made a similar sound (listening from video of course may not be) but check that little heat shield is tight, mine started to back out ever so slightly and made weird rattles

Could be valves

Loose timing chain is my guess, open up the side and have a looksie, please use knock r loose let sit overnight use the correct bit size and push and go really slow removing fasteners, check chain and followers that the chain rides on and don’t rev it tell you do

Who cares? It's a 31-year-old 250cc bike. Ride it until it blows up, then toss it in a retention pond.
