To sign 'motorcycle', hold both hands in 'S' shapes (fists) in front of you, with your palms facing down. Imagine you are gripping the handlebars of a motorcycle. Twist both wrists downward and back up a couple of times, just like you are revving the engine.
Sign 'I', 'want', 'buy', and then sign 'motorcycle' by revving your imaginary handlebars twice.
Point to the person to sign 'he', then sign 'motorcycle' using the revving motion, followed by 'ride' and 'work'.
Point to the vehicle, sign 'motorcycle' with your fists, and then sign 'loud' while using an intense facial expression to show the volume.

Even though a real motorcycle throttle is only on the right side, the standard ASL sign uses both hands twisting together to clearly emphasize the action.
Usually, two quick twists are perfect for the noun 'motorcycle'. If you are describing the continuous action of riding, you might modify the movement to match your story.
They are similar because both involve holding imaginary handlebars! However, 'bicycle' uses a pedaling motion with the fists moving in alternating forward circles, while 'motorcycle' uses a revving motion with the wrists.
