The TTR 125 is a 4-stroke beginner dirt bike. The setup is tailored to be easier to ride than its YZ 125 motocross counterpart. It offers riders a lower seat height, softer suspension settings along with a lower-end performance engine. All these factors make the TTR 125 an ideal beginner 4-stroke dirt bike.<\/p>\n\n\n\n

Seat Height<\/h3>\n\n\n\n
When choosing which dirt bike to buy, pay careful attention to the seat height. Particularly when buying a bike for a new rider. A bike that sits too tall will be difficult to reach the ground with a safe flat foot when stopping or manoeuvring.<\/p>\n\n\n\n
Buying a bike that\u2019s too small will result in an uncomfortable ride. Although smaller bikes are easier to handle, they\u2019re not set up for optimal riding pleasure or performance. If you\u2019re looking at buying the bike for a youngster that is still expected to grow, it\u2019s worth buying a bike that\u2019s slightly too big, allowing the rider to grow in comfort as their size grows into the bike. The Yamaha TTR 125 has a seat height of 30.5 inches<\/strong>.<\/p>\n\n\n\n
Engine Power<\/h3>\n\n\n\n
It\u2019s a terrible idea for beginners to start on a dirt bike with too much horsepower. It\u2019s hard to control and difficult to practice. A bike with too much power will scare a new rider from riding and possibly even scare a new rider away from dirt bikes completely. The Yamaha TTR 125 is a perfect bike to learn on. I know many riders that still ride the TTR 125. It\u2019s amazing how much skill plays a role in speed vs actual engine performance. Give a pro a TTR 125 and he\u2019ll probably still beat me on KTM 300.<\/p>\n\n\n\n
The Yamaha TTR 125 is a single-cylinder, four-stroke enduro dirt bike with maximum torque of 6.64 ft\/lbs (9.0 Nm) @ 6500 RPM. Yamaha claims the max horsepower is 9.39 HP (7.0 KW) @ 9800 RPM<\/strong>.<\/p>\n\n\n\n
Handling<\/h3>\n\n\n

<\/figure><\/div>\n\n\nWhile the TTR 125 may not be the best in its class at handling, speed, or performance, it certainly doesn\u2019t leave anything on the table. As a new rider, the TTR 125 is a great option. It offers a low down center of gravity which helps in the tight twisty corners. To add to the agility, the wheelbase is short which helps to create a tight turning circle.<\/p>\n\n\n\n
You can make some big handling improvements by fine-tuning your suspension over the stock setup. You might also consider making some small changes to get the bike feeling just right for the rider. For example, the handlebars could be rotated forward or back depending on the rider’s height, or completely swapped for a better set of bars. You could also change the position of the clutch and front brake making it feel more comfortable for the rider.<\/p>\n\n\n\n
Top Speed<\/h3>\n\n\n\n
So how fast does a TTR 125 go? A Yamaha TTR 125 has a top speed of around 50 mph. This can me altered slightly by adjusting the gearing of the bike which can make it go faster or slower. The top speed of 50mph is assuming the bike has the stock gearing setup.<\/p>\n\n\n\n
Suspension<\/h3>\n\n\n\n
As with most beginner dirt bikes, the TTR 125 is lacking in the suspension department. Although, if you\u2019re a beginner rider, you\u2019re not going to be able to notice the difference between entry-level and pro-level suspension. The same can be said for ultra-lightweight riders.<\/p>\n\n\n\n
New riders that are not too aggressive on the bike will find that the softer spring rate and valving works perfectly fine on the TTR 125 and 125LE. Although more serious riders should consider upgrading the forks and shocks.<\/p>\n\n\n\n
Brakes<\/h3>\n\n\n\n
One of the key differences between the TTR 125 and 125LE models is the brakes. The TTR 125 has old-school drum brakes on both the front and rear. The drum brakes are more than enough stopping power for beginner riders. Make sure to check the brakes are not worn, have not been sprayed with any kind of lubricant, and that has been set up correctly. The 125LE models come standard with front disc brakes. Disc brakes offer a substantial advantage over drum brakes. The same logic applies – make sure the setup is correct and that the brakes have no oil, dirt, or lubricant on them.<\/p>\n\n\n\n
Jetting<\/h3>\n\n\n\n
Ensuring that the jetting has been fine-tuned will make a massive difference to the performance of the Yamaha TTR125. The stock carburetor is not the strongest selling point of the TTR125. You will need to do some fine-tuning to make sure the bike is not running too rich or too lean<\/a>.<\/p>\n\n\n\n
Gear Transmission<\/h3>\n\n\n\n
What makes this bike so good for beginner riders is the extremely short first gear. For advanced riders, first gear is almost useless on this bike. But, for beginners, having a very short gear helps with practicing gear changes which is arguably one of the most important foundational skills to learn on a dirt bike. A short first gear also means that you don\u2019t need to allow the clutch to ride too far before getting the bike rolling.<\/p>\n\n\n\n
After enough practice with the short first gear, you could swap out the small front sprocket for a slightly larger one which will help to extend the range of the first couple of gears.<\/p>\n\n\n\n
