THE regulations for the Manx Grand Prix will remain substantially unchanged for at least the next three years, the organisers have announced.

The Manx Motor Cycle Club has made the decision following the success of this year's event.

This means the regulations for 2012 will stay in place for the 2013 and 2014 events, with a review of them in time for 2015.

The club said: "It is hoped that this will give existing and potential new competitors the confidence to invest in machinery they know they will be able to use at the Grand Prix for the next three years at least."

One proposed change in 2012 will be that a third class will be re-introduced to the newcomers race.

A total of 55 competitors supported this year's newcomers race and more than 20 per cent of them ran 400/125 machines.

The proposed three classes will mirror the main MGP events as follows:

Class A: 550cc-750cc 4 stroke/4 cylinder, 651cc-1000cc 4 stroke/2 cylinder, 601cc-675cc 4 stroke 3- cylinder, 601cc-1000cc Rotary equivalent

Class B: 201cc-450cc 2 stroke 2 cylinder, up to 650cc 4 stroke/2 cylinder

Class C: up to 125cc single cylinder 2 stroke, 251-400cc 4 stroke 4 cylinder, up to 450cc single cylinder 4 stroke

As with all other races, if, in the opinion of the Manx Motor Cycle Club committee, sufficient entries are not received for a class the club may at its discretion amalgamate that class with any other.
