After the success of the Model A Ferdinando Innocenti needed a refined bike so the Model B was very similar to its predecessor. The main aim was to improve ride quality and comfort while keeping the scooter a low cost form of transport. It was just as simple as the Model A, but the improvements mean it cost more. The Model B was more successful than the Model A selling 35,014 units compared to the 9,669 units of the A.


The Model B is a more refined version of its predecessor the Model A. Its main improvement is in the suspension, the front and rear now has spring suspension, and there is a horizontally mounted coil spring damper on the engine to allow the rear of the engine to pivot.[1] The handle bars have been moved forward and the saddle has been raised,allowing for a larger fuel tank for a more comfortable riding position.[1] The gear changes had been made easier with a handlebar gear changer, which will become standard on all future models.[2] It also had a legshield-mounted speedometer. The tyres were made bigger for greater ride quality, from 3.50*7 to 3.50*8.[1]

Sales and Production

Production of the Model B lasted 15 months, and was over three times greater and three months longer than the Model A.
