Is the TM23 the Right Size?
The TM23 is designed for kids who have outgrown small 110cc models but aren't ready for a full-size frame. Most riders between 4'4" and 5'0" find a comfortable fit, giving them enough height to stay balanced while still enjoying a more powerful bike.
Parents love the TM23 because it bridges the gap between beginner and advanced riding, allowing young riders to build skills without jumping up to a bike that’s too big or too aggressive.
Where the TM23 Performs Best
This model is perfect for:
- Backyard trails and riding loops
- Small jumps and beginner motocross practice
- Dirt roads, gravel areas, and open land
- Youth off-road training and skill building
The TM23 is not street legal and is designed exclusively for off-road use. Always ensure young riders wear proper safety gear including helmet, gloves, goggles, and boots.

The TM23 is built with ease of ownership in mind. Routine items like oil changes, chain adjustments, air filter cleaning, and brake checks can be handled at home with basic tools. Families appreciate how affordable and accessible TrailMaster parts are, making long-term ownership simple.
