Frame cracked!

Hello everyone!
On my Ducati Monster M900 (1997) cracked frame. You can see it on the photos. Crack was discovered after buying the motorcycle. What do you think, how long i can ride on this frame, if I ride on good roads?

Yes, get that welded up, do not ride it that way.

Confirm that both motor mount bolts are not broken, and are tight.

Also inspect the mounting areas on the crankcase for cracks.

ouch, that's pretty bizarre

Been known to happen before... this was mine,

I re-inforced it (plus the lower X section and braced the headstem) with some gussets for the fix...

How long you ride with crack? When found her...

I would not go any further than nursing it home if I didn't have to go far. Once it cracks through you will be on the ground. Also, do follow Speeddog's advice to check the motor mount bolts and case. Looseness there can cause that crack.

Mine has been cracked at the same site on both sides for years. Probably pretty reckless on my part but I still ride the piss out of it. I'll have to pull the engine to gusset weld it.
