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 up to Pre 95), Women’s Class (All Vintage Eras) and two Juniors class for 7-11 & 12-16 Yr Olds for Vintage Bikes up to 125cc and Modern Bikes, 2 strokes up to 85cc and 4 strokes up to 150cc. *Note 7-11 year old Juniors can only participate in rec riding ie, no racing.

Minibike 4 x Rider Relay:
Ocassionally as a novelty event the club runs a minibike relay. Although this is a fun event not to be taken too seriously, we still want to promote healthy competition and have a set of guidelines to follow that gives all machines and teams a chance to be competitive. For this event the following guidelines are in place. Open to Pre-95 small wheel (14″ & 17″) minis, maximum 80cc 2 strokes or 100cc 4 strokes. 

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, the single bike entrants race, the Classic age race and either the clubman or charger race dependant on your ability. The races are usually 4 laps long.

Race 1: EVO 250cc
Race 2: EVO All In
Race 3: Classic Age Race
Race 4: Classic Clubman/Charger Race

If you had 2 bikes, each from a different era, you could duplicate the above (minus the single bike race) and ride a total of 6 races in a race day. There are some that have 3 bikes and ride 9 races.
