The engines, ignitions and carburetors will be approved for a period of nine years from 1st January 2016, after 50 OK and 50 OK-Junior engines have been submitted by each manufacturer during the inspection visit.

Six brands have applied for engine homologation in OK and OK-Junior: REXON Motors (Karlheinz Hahn), Vortex (OTK Kart Group), Parilla (IAME), TE (Tenciengines), TM Racing (TM Racing) and LKE (Lenzokart).

The start of public sale and delivery of the new engines will be at the end of the homologation process after mid-December 2015.
