Vintage Motocross Classes
At Heaven VMX, for the most part, Vintage Motocross is raced in classes separated by the age of the bike. The idea is to have bikes of a similar era, therefore similar level of power and handling, racing together in the same races. We also have a 4 Stroke (All Vintage Eras), Women’s Class (All Vintage Eras) and Juniors class for 12-16 Yr Old for Vintage Bikes up to 125cc and Modern Bikes, 2 strokes up to 85cc and 4 strokes up to 150cc.
The Classes followed in Heaven Events are as follows:
Pre 65: Bikes and modifications produced or specific to the period leading up to Dec 31, 1964
Pre 70: Bikes and modifications produced or specific to the period leading up to Dec 31, 1969
Pre 75: Bikes and modifications produced or specific to the period leading up to Dec 31, 1974
Pre 78: Bikes and modifications produced or specific to the period leading up to Dec 31, 1977
Pre 82: Heaven VMX no longer runs an EVO class. As of 2016, in place of the EVO class, Heaven VMX will be running Pre 82. The rules of the Heaven VMX Pre 82 class are as follows:

Heaven has a one bike/2 classes rule, to avoid racers riding their bikes in classes not really suited to that class. On a typical race day, if you have one bike, you can usually race 4 races. Using a Honda 1979 CR250 Red Devil as an example, and a fine example of a pure bred race bike it is, your race day would look something like this.
You would generally enter your engine capacity class and the ‘All In’ or ‘Open’ Class. The whole race program is run through twice in a day so you would have two races in the morning and two races in the afternoon. The races are usually 4 laps long.
Race 1: Pre-82 250cc
Race 2: Pre-82 All In
Race 3: Pre-82 250
Race 4: Pre-82 All in
If you had 2 bikes, each from a different era, you could duplicate the above and ride a total of 8 races in a race day. There are some that have 3 bikes and ride 12 races.
