The 2012 North West 200 will be held from Tuesday 15 to Saturday 19 May, the Coleraine Club has confirmed.
The club plan to hold daytime practice on Tuesday for the first time, with a Superstock race and a Supertwins event being staged on Thursday evening.
These arrangements are subject to a consultation with interested parties.
The Saturday schedule will remain the same, with five races being held, and the races will not clash with any key international dates this year.
Last year the official Honda team missed the North West because of a clash with a World Endurance round at Albacete in Spain.
The Superstock finishing order and prize money will be awarded on the basis of an aggregate points scoring system over two races for the first time next year.
The first Superstock race will be run on Thursday, subject to a successful consultation, with the second on Saturday.
It is anticipated that the prize money for the class will be increased.
"We are still meeting with the residents and traders around the circuit so nothing has been approved yet," explained Technical Director Mervyn Whyte.
"We believe the new revitalised programme will attract additional spectators and add a little more live action to our Race Week schedule.
"The addition of the Supertwins race is a first for the North West 200 and we will be following the same regulations as the Isle of Man TT who are also set to introduce a Supertwins class for the first time in 2012."
