Yes peter, the project states "Student will research, design, and implement a circuit that will sense the pitch and yaw of a motorcycle and display the readings. The circuit will also automatically turn off the turn signals after a turn is completed. Student will create a PCB layout and will be soldered into a hard case. Then student will develop a mini presentation"
Nowhere does that mention measuring lean angles. Yaw and pitch could each be measured using a compass or an gyro. A compass would be subject to distortion from ferrous objects and electric fields, a gyro would be subject to gradual drift. I suspect you could make either work and the choice will probably be driven by which is easier to obtain and get working.
