KTM Racing has added former factory Kawasaki and Suzuki rider Randy de Puniet and Moto2 rider Thomas Luthi to its testing roster ahead of its MotoGP return in 2017.
After focusing on the 250 and Moto3 classes in recent years, KTM will make the step up to the premier class next year with the RC16.
De Puniet joins KTM after a stint testing for Suzuki, while Luthi has been a mainstay of the 250/Moto2 class since 2007.
The pair join Mika Kallio and Alex Hoffman, who have both already tested the prototype KTM, which began its test programme late last year.
