Kids Motocross

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.



WITH two models for the kids, Husqvarna’s CR50 and CR65 are genuine race bikes, with trick suspension and powerful two-stroke engines.
