American Jeremy Toye will be back for this year's TT races.
His only appearance so far at the event came in 2006 when the 35-year-old from San Diego was the fastest newcomer.
He will line-up on Kawasaki machinery for British Superbike team Sondel Sport Racing and will be joined in a two-man squad by Steve Mercer.
Toye rode a Suzuki for Martin Bullock on his previous experience of the mountain course, picking up three bronze replicas from his three rides and finishing 20th in the Senior TT.
He has gained further road race experience by being a regular at Macua, where he finished third last year.
Mercer was the second fastest newcomer at TT 2009 and last year he finished 17th in the Senior and recorded a fastest lap of 124.658mph.
Sondol Sport Racing is headed up by father John and son Yonny Weedon.
John enjoyed a TT career that spanned 18 years between 1973 and 1991, during which he achieved eleven top ten finishes including being runner-up twice in the Formula Two races of 1985 and 1986.
In all he won twelve silver and 13 bronze replicas.
