Are you thinking about buying a dirt bike for your kid but don’t know which bike to choose or look for? I will give you some background on name brand bikes for kids to help you make a decision. Choosing the right bike for your young rider is very important, especially if they’ve never ridden before. Kids start riding as young as three years old, so once they are able to ride a bicycle without training wheels they should be capable of riding a dirt bike. And please don’t put training wheels on a little dirt bike, that just defeats the purpose.
There are a few factors that come in to play when finding the right dirt bike for a kid. Age, experience, size, and where you are going to ride all come in to play when looking for a bike. There are 50, 70, 80, 90, 100, 110, 125, and 150cc four-stroke dirt bikes that are mostly meant for off-road and trail riding. For the smaller two-stroke dirt bikes, there are a couple different 50s, 65s, and 85cc bikes. These are used for motocross racing.
There are a few different 50cc dirt bikes, but the most common is the Honda CRF50F/XR50R. This is where dirt biking starts for every little kid that has never ridden before. These things are almost bullet proof if you maintain it properly. If you are looking for a first bike for a kid that is under 7 then this is probably the best choice, unless they are bigger/taller than the norm. There is also the Suzuki JR50, Kawasaki KDX50 and Yamaha PW50; all of which are oil-injected 2-strokes that are very light and perfect for the smallest of riders, and the Yamaha TTR-50 which is about the same as the CRF, so it just depends what color you like best.
Honda made the CRF/XR70 and 80cc bikes for kids that are just starting, but a little too big for a 50cc. The 70 has a taller seat height with a little more power than the 50, but the 80 has a clutch which is perfect for training the little ones without letting them ride on a fast bike.
Honda has been known for their XR/CRF100 which reaches to a variety of riders. It has a clutch and is just right for the older kids to learn on if they are too big for the CRF80F. The 100 is a great trail bike because it has just enough power, and it’s also big enough for an adult, so this bike should be easy to find used, and cheap I might add. Kawasaki and Suzuki decided to make the ultimate pit bike for kids and adults. The KLX110/DRZ110 (Parts are interchangeable) has become popular because of how much power it has, or is able to put out, for its size. The 110 is an automatic, so it’s great for smaller riders that want more power than a 70 without going to a clutch yet. Yamaha also has a bigger off-road bike for kids, the TTR-125. The TTR-125 is a popular model for bigger kids just starting out. It has a clutch with enough power to haul riders around, young or old. Honda also has the CRF150F for riders that want more power and a taller ride height than the 100. Although the set-back for the 150 is that it weighs about as much as a full-size motocross bike. These mid-sized off-road bikes are popular for a reason, and this means that they have usually been ridden a lot and probably abused. So if you’re looking at buying a used one then make sure it is clean, it has somewhat low hours, and has been well maintained.
There are a couple different name-brand 50cc motocross bikes for kids, and they are both KTM two-strokes. KTM has the 50 SX Mini, which is for the smallest beginning racers. There is also the 50 SX which is bigger and suits a little taller beginning racer. These bikes both have a one-speed automatic transmission and are liquid-cooled. KTM 50s are expensive, but they are perfect race bikes for your little kids that are ready to tear up the tracks. There are also Chinese companies with 50cc motocross bikes, which aren’t made with as much quality.
KTM and Kawasaki are the only name brand companies that still make a 65cc two-stroke motocross bike. KTM has the 65 SX which is more expensive and usually the racers that are serious buy them. Right from the factory KTM puts aftermarket parts on their bikes, such as VForce reeds on the two-strokes, handlebars, and Brembo brakes. The Kawasaki KX65 is what riders that just want to race buy because they are so cheap. That does not mean that they aren’t fast, they just aren’t always as reliable and don’t have a very high re-sale value. Both are great race bikes for intermediate younger riders in around the age 7-10 that have been riding for some time. These bikes are usually not used for trail riding because they are not as easy to ride and lug around as a four-stroke is.
85cc motocross bikes are the start for a young teen aged racer. They have more power than most any kid could use, which makes these bikes a blast for adults or adrenaline-junkies as well. KTM, Suzuki, Kawasaki, and Yamaha all make an 85cc two-stroke mx bike. Honda put a stop to their two-stroke inventory after 2007, but people still buy their late model bikes. Instead, Honda wanted to start a revolution for mini-bikes with their all new 150cc four-stroke motocross bike. It was well talked about, but once it came out it died slowly. They are powerful bikes and are easier to ride than an 85, but the weight and cost lost it for them. Usually these CRF150R’s (Big and small wheel) were bought by racers with money because they also needed quite a bit of maintenance. If you have money and your kid loves the easy ride-ability of a four-stroke then this would be a good race bike to buy.
If you don’t have a deep pocket, then an 85 or 100/105cc two-stroke stroke is a great choice. Your kid will love you for getting them one of these bikes; before they flip it at least once, that is. If you find someone selling a used 85 that hasn’t been flipped, then you’re either lucky or they’re lying. 85s are pretty much race-only bikes. I’ve trail-ridden with one, and it was not very fun because of the lack of power down low. The Honda CR85R and Yamaha YZ85 hit harder and are more snappy than the others because they don’t have a power valve. KTM’s 85 SX comes with aftermarket goodies from the factory like all of their other bikes, so it’s probably the fastest out of the lot. Kawasaki’s KX85 and Suzuki’s RM85 are very similar and are used by many riders that are on a budget because of how cheap they can be. Honda and Suzuki both have a larger wheel 85, which helps those taller kids that quite aren’t ready for a 125 or 250f.
Kawasaki and KTM have a big-bore 85 to compete in the supermini class (86-112cc). Kawasaki’s KX100 is a big wheel and has plenty of power for any young racer. KTM has a 105 SX which is one of the best power-to-weight ratio bikes you can buy, and also has larger wheels. When it comes down to choosing an 85,100/105, or a 150cc four-stroke motocross bike for your kid, it depends how big your pocketbook is, what fits your kid, and what color you like best.
