Dirt Bike Size Chart according to age

If you want to get a dirt bike for you or your kid (under 15), you must consider the age-size factor before buying one.

  • As their first bike, you can give a dirt bike a 50cc engine with twist and throttle, for 3-6 years old kids. This will be helpful for them to learn balance and control over speed. This type of bike can be considered to be the best and safe as their first ride.
  • The next level bike will be a 50cc semi-automatic dirt bike for 5-9 years old kids who’ve learned to balance twist and ride. These bikes have more appropriate seat height for the age group.
  • Kids from 8-11 years age group and who’ve ridden before will easily adopt using a standard gearbox, and for that, a 65cc mini dirt bike is the best option as it comes with the same controls as a full-sized dirt bike. If they are riding for the first time, start with the 50cc twist and go model before trying anything else.
  • Choosing a dirt bike for 11-14 years old kids can be a bit complicated as their height, and weight will differ. 110-150cc, 4 strokes, or 80-100cc 2 strokes bikes will be a perfect match for them. Kids with experience can advance to bigger and stronger engines.
  • Experienced 15-17 years old kids will be mostly riding an adult-sized bike, but less experienced ones will need smaller ones. 125-150cc 4 strokes or 100-125cc 2 strokes are perfect for them.
  • Experienced adults should not jump straight to 450cc race bikes. Start with a 250cc 4 strokes race bike and then gradually proceed to ride powerful dirt racing ones.
