would a 6061 aluminium frame be suitable for dirt jumping?
Throw everything in your house out into the streetsThere goes your new pit house.
If you are considering using the bike for REAL dirt jumping then no, I'm afraid that the frame won't be strong enough unless the tubing has a wall of at least 2mm and it is annealed and aged to T4 or T6So, what you are looking at is a frame that will be heavier than a well-engineered 4130 frame and cost twice as much with a shorter life expectancy even if you use thick walled tubesWelding up an aluminum frame is just the tip of the iceberg- the after treatment is what is really important.
