Yamaha TT-R50E specifications
Yamaha · Youth trail
Ultimate Motorcycling says its experienced test rider had no problem handling the 2022 bike. The article describes the TT-R50E as a bike for spending time on easy terrain and learning the ropes of dirt bike riding, using the throttle, the auto-clutch three-speed gearbox and the brakes to start, and growing into sliding the rear tire and getting some air.
The same source says there is enough engine compression braking that the drum brakes will likely see only emergency use, and that they are effective.

Total Motorcycle describes a 49cc air-cooled SOHC four-stroke that is smooth, reliable and perfect for kids and smaller beginners, through a three-speed automatic-clutch transmission, in a curved steel backbone frame with three engine-mounting points.
The write-up adds that the conventional fork with 22 mm sliders gives 3.8 inches of travel. Dirt Rider noted an older test where electric start, YZ styling, a low seat and a three-speed semi-automatic transmission came at a lower price than the Honda.
Fit and how a child outgrows it
A 21.9 in seat is the lowest of Yamaha's trail bikes here, and with 5.3 in of ground clearance it is meant for flat, easy ground. The gearbox has three speeds and no clutch lever, so a child's job is throttle and brakes. The parent can limit the throttle stop.
The TT-R50E’s listed wet weight is 128 lb. Assess the rider’s reach to the controls and ability to handle the machine with qualified supervision. A used example’s condition and service history must be checked directly; a youth model is not evidence of light use.
Against the TT-R110E
The TT-R50E suits a small child at the very start of riding, with a parent nearby on flat ground. Ultimate Motorcycling's point about drum brakes and engine braking means the bike is forgiving. But a child will outgrow it quickly.
TT-R50E against the CRF50F and TT-R110E
Honda's CRF50F is the direct rival, and Yamaha's TT-R110E is the next step up.

2027 Yamaha TT-R50E questions
Does the Yamaha TT-R50E have a clutch?
It has an automatic clutch with a three-speed gearbox, as listed by Total Motorcycle. So the child needs only manage throttle and brakes.
How tall is the Yamaha TT-R50E?
Yamaha lists a 21.9 in seat and 5.3 in of ground clearance, low enough for a small child to put their feet down.
Are the TT-R50E brakes good?
Ultimate Motorcycling says the drum brakes are effective and that compression braking means they will likely see only emergency use.
A 21.9 in seat is the lowest of Yamaha's trail bikes here, and with 5.3 in of ground clearance it is meant for flat, easy ground. The gearbox has three speeds and no clutch lever, so a child's job is throttle and brakes. The parent can limit the throttle stop.
At 128 lb wet it is still heavy for a very small rider to pick up, so the first sessions should be on soft grass. Most children move on to a 110 within a season or two, which is why a used TT-R50E often has very light use.
The TT-R110E costs $550 more ($2,449 against $1,899), has a 4.5 in seat rise (26.4 in against 21.9 in), a four-speed with a manual-style clutch, 7.1 in of clearance and 31 lb more weight. The 50 is for a child who has never ridden. The 110 is the step after a season or two.
