No, the motorcycle is separate test. On A CDL, they show the "endorsements" on the back and with a motorcycle endorsement, it becomes a Class AM rather than just a Class A. Class A is for anything in excess of 24,999lbs GVW. Class "B" is for anything less than 24,999lbs GVW, and Class "C" is what most folks have than don't drive for hire. I don't drive for hire anymore but am required to maintain my CDL. I drive 12yd dump trucks rigged with sanders when we have our infrequent ice and snow storms here. I love throwing dirt at idiots on icy roads. Once or twice a year I get roped into dragging something heavy with the company's 6 axle haul truck. I try not to get caught but it happens. The reason I try not get caught is simply that where I work now doesn't pay for experience with that type of stuff. I ran rigs with up to 13 axles "back in the day" and now I would just rather not fuck with it.
ALL airplanes land. One way or another but ONLY if they take off first.

The SEL represents land operation only. No sea-planes or amphibious stuff. I do have a "conventional (tail-dragger)" endorsement for that license which allows me to legally fly old shit with tail wheels rather than just the "tricycle" geared general aviation planes like most are nowadays. The P-38 and P-39 are tricycle geared. P-51's and the like are conventional geared.
As for forklifts? I hate em. Ours are all terrain versions and not fun like the little wheel versions you see in ware houses. I can run the wheels off 'em and have yet to turn one over. I ran one beast occasionally at former employer's and it was rated at 25 tons. It was a fucking monster. We used it to move loaded semi trailers and whatever else got in our way. I wanted so much to take it out the freeway during rush hour and clear a path. LOL
