Now, what I would say is practice makes perfect. Your parents should keep practicing on that speed. Now, if you want to change the speed in multiplayer, after you choose "Versus," you go up 1 to Settings. You do not choose Single or Team, you go up 1. After choosing it, you will see what I am talking about. You can change the speed from 50cc all the way to Mirror Mode, which means that it is still 150cc, but the track is backwards. I'm sure that if your parents have not beaten 150cc on Single player Grand Prix, Mirror Mode will not be unlocked. You will also be able to choose the difficulty of the CPU, choose how Aggressive your items are, and also how many races you can do. After you are done, go to "OK." You are now ready to play at either a faster or slower speed!

You can restrict its performance but no you cannot change from 100cc to 50cc unless you have a 50cc engine for the same model bike, but requires more work than worth as you would need to downgrade other parts.
