Bonetti became the first Italian to win a race in the 90-year history of the North West 200 when he took the chequered flag on the Thursday night of racing over the Triangle circuit.
The fastest Italian ever around the Isle of Man Mountain Course, the Irish rider finished sixth in the 2019 Lightweight TT.
Hind, a rising star of the sport, built on his second place in the 2018 Newcomers Manx Grand Prix by taking a brilliant brace of wins in both Manx Grand Prix Lightweight races in August.
The 19-year-old also secured an impressive third place in the Lightweight Classic TT behind Bruce Anstey and Davey Todd.
He was also leading the Junior Manx GP race until his Yamaha R6 developed an oil leak, but not before he had set a new lap record with a speed of 121.77mph from a standing start.
Hind led the Senior Manx GP on the opening lap until the R6 developed a throttle problem at Ballaugh Bridge and he will now make his TT debut in 2020.
Masayuki will have a Supersport ZX6 Kawasaki at his disposal, in addition to his Kawasaki Supertwin.
