Martin Jessopp will make his debut at T.T. 2014.
After years of speculation about him racing around the Mountain Course, he will compete for his regular Riders Motorcycles team which is owned and run by his father Phil.
The 28 year-old from Yeovil will ride a BMW 1000cc bike in the Superbike, Superstock and Senior races.
Jessopp has been a regular in the British Championship paddock since 2004 but in 2012 contested the World Supersport series.
He has plenty of road racing experience too having raced at the North West 200 since 2006 and at Macau since 2007.
He finished second to Michael Rutter at the Macau Grand Prix in both 2011 and 2012.
