A suitable dirt bike for a 13-year-old must match the rider’s size, strength, judgment and training. Age alone cannot establish that a motorcycle is a good fit. Start with an in-person fit check and a supervised lesson, then compare the controls and riding conditions below.
For a smaller rider who fits it, the Honda CRF110F offers an automatic clutch. The standard-wheel Honda CRF125F adds a manual clutch and a taller chassis. The Razor MX350 is a compact electric option for much more restricted surfaces. These selections compare manufacturer specifications and safety guidance; none is a universal recommendation for every 13-year-old.
Three options to compare
| Model | Why consider it | Fit and controls | Key restriction |
|---|---|---|---|
| Honda CRF110F | Learning gears without a hand clutch | 25.9-inch seat; four-speed automatic-clutch transmission | Parent must assess readiness and fit; off-road only |
| Honda CRF125F, standard wheel | A rider ready to learn a manual clutch | 29.1-inch seat; four-speed manual transmission | Taller and heavier than the CRF110F; off-road only |
| Razor MX350, high/low-speed version | Supervised electric riding on suitable level ground | Twist-grip throttle; hand-operated rear brake; 140-pound rider limit | 13+ in High, 8+ in Low; flat, dry, debris-free surfaces |
Honda’s U.S. manuals emphasize physical ability, coordination, maturity, instruction and supervision rather than granting automatic approval at a particular birthday. Check the manual and labels supplied with the exact bike. For every model, an age minimum or weight limit is only one part of the decision.
1. Honda CRF110F: an automatic-clutch trail option
The CRF110F combines a 109cc four-stroke engine, fuel injection and electric starting with four gears and an automatic clutch. The rider still shifts gears, but does not operate a hand clutch. Honda also lists an adjustable throttle limiter, which a responsible adult should set and check according to the manual.
Its published seat height is 25.9 inches and curb weight is 169 pounds. That lower seat can make it worth trying for a smaller teen, but the motorcycle’s weight still matters when balancing and maneuvering it. Honda’s CRF110F manual specifies a 132-pound maximum load including the rider and accessories; check the exact model-year manual before purchase.
Choose it if: the rider fits comfortably, stays within the load limit and is ready to learn throttle, braking and gear selection with adult instruction. Pass if: it feels cramped, the rider cannot manage its weight or you are buying it solely because “110cc” sounds appropriate for an age.
Check Honda’s CRF110F details and locate the matching Honda owner’s manual.
2. Honda CRF125F: a manual-clutch option with more room
The standard CRF125F uses a 125cc four-stroke engine, fuel injection, electric start and a four-speed manual-clutch transmission. Its 29.1-inch seat and 17-inch front/14-inch rear wheels distinguish it from the separate Big Wheel version.
Honda lists a 194-pound curb weight for the standard model. Its CRF125F manual gives a 176-pound maximum load including the rider and accessories. That load limit describes what the motorcycle carries; it is not the motorcycle’s own weight.
Choose it if: a fit assessment supports the larger chassis and the rider is ready for clutch training. Coordinating the clutch, throttle and gears adds a skill to learn. Pass if: the teen cannot reach and work the controls easily or hold the bike up with confidence.
Check the trim: CRF125F Big Wheel has a 30.9-inch seat and 19-inch front/16-inch rear wheels. Do not order it assuming it is the same size as the standard model.

3. Razor MX350: a limited-surface electric alternative
The high/low-speed MX350 has a twist throttle, a hand-operated rear brake and a 24V sealed lead-acid battery system. Razor specifies a 140-pound maximum rider weight. Check that the actual bike has the high/low switch; do not assume older units have identical controls.
Age and settings: the current manual recommends 13+ in High and 8+ in Low. High is the factory default, and Razor recommends Low while learning. Meeting an age recommendation does not prove a child fits or is ready. An adult should check the setting before use.
Important terrain limit: although it looks like a motocross bike, Razor’s manual calls for flat, dry surfaces without loose debris and warns against rough, uneven or slippery ground. Do not select it for rocky trails, jumps or racing. Use it only where permitted, away from traffic.
See the exact MX350 product and read its high/low-version manual.
Check readiness and fit before buying
The Motorcycle Safety Foundation’s parent guide provides a useful readiness checklist. With the engine or power switched off and riding gear on, confirm that the teen can:
- Sit comfortably with both feet touching the ground and support the bike’s weight.
- Turn the bars fully and reach the throttle, brake controls, gear lever and clutch where fitted.
- Understand instructions, follow rules and respond sensibly when something goes wrong.
A seat-height number cannot capture seat width, suspension movement, boot fit or a rider’s reach. Have a qualified instructor or dealer help with the actual bike. Do not buy an oversized motorcycle for a child to grow into. If readiness or fit is doubtful, postpone the purchase.
Plan for training, gear and supervision
MSF DirtBike School provides hands-on instruction and advises supervising riders under 16. A 13-year-old needs active adult supervision even after learning the basics. Ask the course provider about bike fit, equipment and the training suitable for a first-time rider.
For off-highway motorcycling, MSF recommends a properly fitted DOT-compliant motorcycle helmet, eye protection, gloves, long sleeves, long pants and over-the-ankle boots. Choose motorcycle riding gloves and boots that let the rider operate the controls. Casual fashion jackets, sandals and fingerless cycling gloves should not be treated as a complete motorcycle protective kit.
Follow the exact vehicle manual as well. Razor calls for a securely fastened safety helmet, elbow and knee protection, suitable clothing and footwear; charging is an adult responsibility using the recommended charger. Protective equipment reduces some risks but cannot make unsuitable riding conditions acceptable.
Budget beyond the bike
Include training, correctly fitted gear, transport to a permitted riding area, routine maintenance and replacement wear parts. For a used bike, have a competent mechanic check its condition, controls and any modifications. Obtain the matching manual and ask about service support before committing to a purchase.
Honda identifies these CRF-F models as off-road only. Nothing in this list is a recommendation for street riding, carrying a passenger or unrestricted use on public land. Check the rules and access conditions of the actual riding area; an electric motor does not automatically create permission to ride.
Questions parents often ask
Is 125cc the right size for a 13-year-old?
Engine displacement is not a fit standard. Even the two CRF125F trims have different seat heights and wheel sizes. Assess the exact machine, the child’s ability and the manufacturer’s instructions instead of choosing by age and engine size alone.
Is an automatic clutch fully automatic?
On the CRF110F, the clutch operates automatically but the rider still selects gears. The CRF125F has a hand-operated clutch. Neither removes the need to learn braking, throttle control and safe stopping.
Is an electric dirt bike automatically safer?
No. Fit, controls, speed setting, supervision and the permitted surface still matter. The MX350’s dirt-bike styling does not override the restrictions in its manual.
Which option makes sense?
Try the CRF110F first if its smaller chassis, load limit and automatic clutch match the rider. Compare the standard CRF125F when the rider needs more room and is ready for a manual clutch. Consider the MX350 only for its specified surfaces and limits. A supervised lesson and a successful fit check should come before the final purchase decision.
