2024-T3 is easy to work with, but you'd probably need a piece 1/8" thick or more; it bends fairly easy. 6061-T6 is the tough stuff used a lot in aircraft, and half the thickness would probably be better than 2024. Don't expect to bend it at home, though - for one thing, you'd probably just break it. Can't tell dimensions from the pic, but if that piece is around a foot long, and supported on the sides, I'd think an 1/8" thick piece would actually be overkill, .090 would probably work, maybe even .060. When you get the aluminum, the place you get it might have better recommendations. T6 is surprisingly hard, cuts slow with a bandsaw, and edge cleanup will take a while to get smooth. Smooth those edges for sure, hard AL can cut you easy.

I use 6061 because you can drill it an tap it, stands up to the vibration troubles. I never used 2024 so I can't comment on it...

Your right. That looks like a pain to install. The only thing I dont like about skid plates is the mud that gets trapped behind them.

It's a lot softer, easier to work, and I think it may weigh less. Used a lot in aircraft where it doesn't bear heavy loads; it's fairly easy to bend for odd shaped brackets. 6061 is a far better choice for motorcycle use I think, even if only for the vibration. 6061 tends to crack if you bend it with the grain, though.
