Having starting or running problems with your TTR125? There’s a good chance that the stock carburetor is your problem. Instead of spending hours trying to fiddle with it, a carb swap can save you a lot of headaches and make your bike start easier and run much cleaner. Here’s a step-by-step video tutorial on how to convert to the Mikuni VM24 carburetor. If you’re unsure about this conversion or have questions on why you should do it, read all the details on swapping out the stock carb HERE.
Buying a dirt bike for your kid can be one of the best feelings for both your kid, as well as yourself. Choosing the right one can be a hard decision, but either bike can fit the bill. There’s a few major differences between the Honda CRF50F/XR50R (Same bike, just different body style), and the Yamaha PW50, so lets see what each of them have to offer.
For both being 50cc, the engine’s are quite a bit different. The Honda has an air-cooled four-stroke with a three speed semi-automatic transmission, while the Yamaha has a two-stroke, oil-injected engine with a centrifugal-clutch. They are both pretty much bullet-proof as long as you regularly change the oil and keep the air filter clean.
Neither have electric-start, but the Honda engine is a more versatile. In stock form it’s already more powerful and has three gears, making it easier for your kid to get past certain obstacles. The aftermarket has a lot more to offer as well for the CRF/XR 50. It is one of the most popular pit bikes for adults, so there’s plenty of engine, suspension, handelbars, and other hop-up parts available to fit the riders needs.
However, if you want a light and mellow power-band without having to change gears, the Yamaha is a great starting point. It also has a throttle-lock feature that you can set to lock the throttle at a certain position so that your kid doesn’t hold it wide open and get into trouble as easily.
Neither have that good of suspension from the factory. The CRF50 is going to be a little better, but still isn’t good enough for racing on. Of course, these are just kids dirt bikes for beginning riders, so they are plenty good for trail and play riding. The Honda once again has plenty of aftermarket options for forks, shocks, and swing-arms if you are willing to shell out the dough though.
Size may be the most important factor, depending on how small your little boy or girl is. If you’re looking for the lowest seat height and lightest bike, the PW50 has the CRF beat. Its seat height is only 19 inches, and weighs a shocking 86 pounds when wet with fluids. This is substantially lower than the 110 lbs of the Honda.
In The End…
It depends on the nature of your kid. If your boy or girl is small and barely knows how to ride a bike, the PW50 is probably the better choice, due to it being smaller, lighter, and smooth on power. However, almost all kids grow out of the PW’s within the first year, so there’s a good chance you’ll be needing another bike soon after. Whereas the Honda will last a little longer since it’s a little more powerful, has a 3-speed transmission, and plenty of aftermarket parts for upgrading. You can usually get a couple years out of the ol’ Honda 50 before needing a bigger dirt bike, depending on how fast your kid grows and learns.
