TTR50 Specs – Complete Review of Yamaha Kids Dirt Bike [2023]

The Yamaha TTR 50E, also known as TTR50, is the bigger brother of the PeeWee50. As a result, TTR50 specs are quite different even though both are 49cc dirt bikes. It’s one of Yamaha’s stable of great mini dirt bikes.

TTR50 is perfect for kids ages 4 to 7. It first came out in 2006 to help young PW50 riders adjust better to the PW80. Fast forward to today, the 49cc air-cooled, 4-stroke is a popular learner bike. It competes for the top spot with its tiny brother and the Honda CRF50. 2023 model retails for $1,749 USD.

There’s no difference between the 2023 Yamaha TTR50 compared to the 2022 model in price, features, and style. Riding this bike teaches them how to shift gears compared to PW50 that is fully-automatic.

Now let’s take a look at what makes this dirt bike a good buy…

Top features of the Yamaha TTR50

The top features of this mini dirt bike are its:

  • Electric start
  • Smooth 4-stroke engine
  • 3-speed automatic-clutch transmission, and
  • Manageable seat height

The electric start makes kickstarting struggles out of the equation. Having the push button means that your kid can refine their skill on the bike and avoid frustration.

The tuning on this 4-stroke is smooth and predictable. If your kid loses control and gives too much throttle, they won’t get bucked off the bike by sudden speed.

Shifting is a necessary part of riding dirt bikes, and the 3-speed automatic clutch makes learning it easy. Lastly, the TTR50 seat height is still manageable for a wide range of young riders at 21.9 inches. Taller or older kids can opt of bigger brother TTR110.

The Yamaha TTR50 Review

Raw numbers and figures don’t always give a complete picture. Here’s what you should know if you’re planning to buy this bike.

Team Yamaha Styling

This kid’s dirt bike shares the same design and bodywork as the YZ series. This gives it a race-ready look. The number plate attached to the front fender drives the message home.

TTR50 Performance

The engine on the TTR 50 excels at smooth power. It puts it out at a measured and predictable rate that builds rider confidence. 

These two features make it great for trail riding. It comes with spoked wheels that grip the dirt with sticky, knobby tires. And it has an exhaust with a spark arrestor. This means you can go trail riding without making too much noise.

The TTR50 has several safety features going for it. There’s a throttle adjustment screw that keeps the top speed where you want it. The bike won’t start unless the key (which you keep) is in the ignition. And you can fit training wheels on it to help your kid balance.

The comfortable seat is also low. Compared to racing dirt bikes, the difference in height is around 4 to 5 inches.


This Yamaha is a convenient package. It comes with a push-button electric start — no kick start. It has a folding side stand — no need to lug around a bike stand. And it has a digital ignition for a reliable startup.

The TTR50’s battery is a great source of this convenience, and it needs proper care. Hook it up to a trickle or smart charger, so it can last for several years.

Handling of the TTR50

At 128 pounds, the TTR50 is the heaviest trail bike out of the four. (The other three are the PW50, Honda CRF50, and Suzuki DRZ50.) But it’s a solid ride. The 3-speed constant mesh transmission slowly immerses your kid into shifting. Cleated folding foot pegs guarantee a non-slip grip.

The front and rear drum brakes also match the engine’s output with good stopping power. It’s an easy bike to handle and doesn’t spring surprises. However, the factory shifter pedal tends to bend after too many left-side drops. Replace it with an aftermarket shift lever to make it tougher.

“When I was 6 years old, my family and I were riding dirt bikes and four-wheelers at the family farm….[My dad] asked me if I wanted to ride the dirt bike, which was a Yamaha TTR-50, and I said yes. Once he showed me how to ride it, I knew I was meant to be on a bike.”

Mikayla Moore, up-and-coming road racer, via 2020 interview

The quality and predictability of its SOHC engine makes the TTR 50 pit bike conversion-friendly. Plus, its compact size makes it easy to grip the bike and control it (regardless of the rider’s age).

The high-quality Mikuni carburetor provides good throttle response and hassle-free starting, too. (Mini dirt bikes are known for being “cold-blooded,” or hard to start.)

Rival Brands of TTR50

Not all parents are willing to start their kids on a TTR50, which makes the PW50 a rival Yamaha model. The Peewee is the lighter and shorter of the two.

It stands 18.7 inches tall and weighs 90 pounds. Despite being heavier and taller, the bigger Yamaha has better suspension. It has about an inch more of travel, which means a more comfortable ride. When you’re concerned with the noise, Yamaha TTR50 is less noisy than PW50.

When it comes to the battle of TTR50 vs CRF50F, it’s neck-to-neck and boils down to preference. Check out the table below for a quick comparison.

Yamaha TTR50 vs Honda CRF50

One thing the CRF50 has to its clear advantage is the availability of aftermarket parts and resale value. It has simply been around for much longer.

Resale Value

The secondhand market is decent for the TTR50. It has a Kelley Blue Book trade-in value of around $910 (for 5-year-old or newer models). Listing prices at dealerships are around $1,425 for the same model range.

Final Thoughts on Yamaha TTR50 Specs

Even though it’s not as popular as the PW50 shown above, TTR50 parts are also widely available and easy to find. PW50 and CRF50 do take the top spots for Best 50cc Dirt Bike.

The Yamaha TTR50 is the bike for tall or skilled young riders around the ages of 4 to 7, depending on their height. It can build a great foundation and will make switching to bigger bikes easier.

Its main advantage is its electric start. Take care of the battery, and your kids will definitely get a few years of riding done on this bike.
