Casio Auto Race / Le Bol D'or Moto (1983, LCD, Watch Batteries, Model# CG-105)
Odd that it's called Auto Race when it's obviously motorcycles... Neat controls, left-right slider for steering and the large vertical slider controls your speed.
French version called Le Bol D'or Moto released by Lansay
(still says Auto Race on the game itself though):
