Technically, Yes.
The course of CBT will include a session on gears regardless of whether you are riding an automatic scooter, although obviously you will not have the opportunity to practice changing gear unless you ride a geared bike.
We would advise you to take your CBT on the type of machine you intend to ride. If you change your mind at a later time, we can offer a simple 1-hour session specifically aimed at giving you the skills and practice of riding a geared motorcycle.
