Start With Fit

How to Choose the Right Dirt Bike Size

Age can provide a starting point, but seat height, inseam, strength and experience are more useful. A rider should be able to balance the bike, reach the controls and operate the brake confidently. Do not choose a larger dirt bike only so a child can grow into it.

SK110E 25 inches Automatic Electric Smaller or newer riders
TM10-110 26 inches Automatic Electric Beginner and youth riders
TM23 29 inches Semi-automatic Electric Growing youth riders

Buying Guide

What to Compare When Shopping for a Dirt Bike

Seat Height and Rider Fit

The rider should be able to balance the bike and confidently reach the handlebars, foot controls and brake. Compare the listed seat height with a bike the rider already fits whenever possible.

Automatic or Manual

Automatic and semi-automatic dirt bikes let newer riders focus on balance, braking and steering. Manual models add clutch and shifting skills for experienced riders.

Electric or Kick Start

Electric start provides convenience, while models with both electric and kick start provide a useful backup starting method.

Common Questions

Dirt Bike FAQs

What size dirt bike should I buy for a child?

Start with seat height, inseam and experience instead of age alone. The SK110E and TM10-110 are the smallest current TrailMaster options, while the TM23, MK110ES and MK125E provide taller youth-sized platforms.

Are automatic dirt bikes better for beginners?

Automatic and semi-automatic models reduce the number of controls a new rider must learn at once. This allows the rider to concentrate on balance, braking, throttle control and steering.

Do you sell adult dirt bikes?

Yes. The TrailMaster MX250 Pro is a full-size manual dirt bike with a 35.5-inch seat height for experienced teen and adult riders.

Can a dirt bike be shipped to my home?
