holiday period, with Formula Shell Boxing Day Classic featured as the main course.

The dirt will be flying, engines revving and noise in abundance as riders challenge for honours in the sport's biggest single day event of the season.

Expected to return for the defence of his 125 B class title is Robbie Smith, however, he has been slowed in recent weeks by an injured shoulder and could find it difficult against hungry opponents.

Chief among those is Aaron Pace, who surrendered the title to Smith a year ago and would dearly love to regain possession of such. Nothing would please the 18-year-old more than a victory on Tuesday, before he flies abroad to attend college in January.

Other potential winners include Stephan Lightbourne and Kyle Constable. For Constable the race will mark his first Boxing Day outing in this class.

A sore point exists as current Pepsi National Series points leader Kemo Simons will not be involved due to injury.

Meanwhile, the 125 C class appears a toss-up between Jason DeSilva and Neal DeGrath.

Among the 80cc class Jamel Hassell is expected to further assert his domination, but fast improving Craig Panchaud would sincerely like to dent his hopes.

The day's race format will feature two motos per class. Each moto for the 250 and 125 classes will be of 25 minute duration. Admission for the event is adults $3 and children under 12, $2.

ON THE MOVE -- Young Kyle Constable will be hoping for great success at the Formula Shell Boxing Day Classic among the 125 B class.
