Different bikes suit different riders, and there’s a variety of classes for different age groups.
Racing classes & ages
There’s quite a lot of overlap in the classes, which means you don’t have to buy a new bike every time they have a birthday, but physical growth is a big determining factor in what bike suits which rider – our project bike pilot, Damien, has only recently turned 12 but his tall physique suits the CRF150RB big wheel, and he should get a couple of years out of the bike before he grows out of it.
Under sevens can get involved in fun riding in non-competitive events, riding 50cc machines. Kids 7-12 can race 50-65cc machines.
85cc two-strokes and four-strokes to 150cc are usually sold in standard and big-wheel versions – standard wheel bikes are for racers 9-13 years, big wheel machines for kids aged 12-15.
125-200cc two-strokes and 200-250cc four-strokes are for kids over 13.
Check with your club about what classes of racing they offer, because if they don’t have the numbers for a particular class you might be mixed with other classes, or possibly miss out altogether.
