He joins fellow road racer Conor Cummins, pro golfer Tom Gandy and cyclist Tom Mazonne in benefiting from help from the company.
’Since I was a child I’ve always had a passion for motorsport but understand that it is a big commitment both physically and financially to pursue this dream,’ he said.
’To have this support from the Steam Packet Company will be a massive help and allow me to concentrate on the competitive side of the racing.’
Among Nathan’s plans for 2020 are to ride in the NorthWest 200 in Northern Ireland, the TT and Classic TT, the Ulster Grand Prix and the Southern 100.
