The top speed of a 100cc dirt bike is 50-60 miles per hour. Even at 80 mph, which is quicker than most cars travelling on residential streets, the top speed depends on the engine’s tuning and the presence of an extra carburetor.
Factors That You Must Know When Buying a Dirt Bike:
1. Seat Height
Before tackling any other aspect of the bike, make sure the seat is at a comfortable height for you. The numerous 100cc bikes can be used to help your child better appreciate the difference in height. Always wear high heel riding boots rather than regular sneakers when purchasing a bike from a shop, and always bring the same footwear with you when you do so. It’s possible to test out the identical pair of boots that you purchased.
The suspension will have to work harder and you’ll hear and feel more bumps if your feet aren’t on the ground. In order to ensure that your child has a pleasurable experience while riding his or her bike, keep seating in mind at all times. You may be able to lower the suspension and lower the handlebars on some dirt bikes to make it easier for your child to reach.
You can also ask the store if he or she can cut the seat so that your youngsters can rest their feet on it. Alternatively, If you teach your children to ride a dirt bike at a young age, they will have a greater sense of control over the machine.
2. Size of the Engine
For children ages 5 to 9, a 100cc engine is appropriate. Because the engine isn’t too powerful, they have an easier time manoeuvring the bike. For kids who have never ridden a dirt bike before, the smallest engine size is 50cc, which is ideal for beginners. Having a 100cc engine gives your child more power and room to practise throttle control.
Adult motorcyclists can choose from a 50cc to a 250cc engine. Kids enjoy the same amount of speed as adults do when riding a 100cc at 50 mph. Depending on how well your child does on his current dirt bike and his level of confidence, you may want to upgrade to a more advanced model.
You’d also know when to upgrade to a more powerful engine if you knew these things.
- When riding a bike, the leg of a youngster rises to the level of his ear.
- Motorcycle racing can be a good option for them.
- Instead of using an automatic bike, they prefer to use a manual one.
- Better suspension, brakes, and larger wheels would be on your kid’s shopping list. More powerful bikes have all of these qualities.
Inexperienced riders can benefit from even the tiniest of changes in engine size. Better clutches, gearboxes, and other components are made possible by larger engines.
3. Size of Wheels
Bikes with 125cc or fewer engines have either large or small wheel options. Bikes with 19-inch front wheels and 16-inch rear wheels are known as “big wheel” dirt bikes. Small wheel dirt motorcycles, on the other hand, have a 17-inch front wheel and 14-inch back wheels. The swingarm, gears, and suspension of a bike with two identical wheels might vary greatly depending on the wheel size.
There are pros and disadvantages to both wheel styles. Stability is increased by using a larger wheel. Small wheels, on the other hand, are lightweight and better suited to tight turns. Big wheel bikes are heavier than small wheel cycles, but they have more tyres.
Due to the size of the frame, wheel size also has an effect on the vehicle’s height. If you allow your children to ride bikes with different sized wheels, it will be easier for them to learn.
4. Type of Engine – Two-stroke vs. Four-stroke
Two-stroke and four-stroke engines are available on dirt bikes with less than 100cc of displacement. Four-stroke creates power for every two crankshaft rotations, hence this has a direct effect on the bike’s speed. It makes riding a bike more comfortable and less prone to jolts because to its suspension design. Two-stroke engines, on the other hand, have a higher power-to-weight ratio since each crankshaft movement results in more power.
In other words, a 65cc two-stroke engine may match the speed of an 80cc to 100cc four-stroke engine, in terms of horsepower. There is a big difference between a two- and four-stroke engine depending on the type of track it can run on. When it comes to trail riding and pleasure riding, two-stroke engines are always preferred. However, if the tracks are bumpy, four strokes would be more stable and controllable.
5. Electric vs. Kick Start
In most entry-level bikes, there is usually a push-button option for starting the engine. Determine which of the two requires the least amount of work to get the engine going for the youngsters. Electric starters require little more than a little TLC, and you must utilise them with care.
To get an engine going, kids have a hard time operating a kick starter. However, this only occurs if you are a newbie to kick starter and get used to the kick action afterwards. In current models of dirt bikes, even adult bikes have the electric starter option, which was previously only available on older kinds of dirt bikes.
A dirt bike with a 100cc or smaller engine is likely to have an automated clutch. An automatic clutch makes it easier for kids to learn how to steer and balance because they don’t have to worry about shifting gears. The Suzuki JR80 is a dirt bike model that has a manual clutch, making it a good choice for those who want to start before upgrading to a more advanced model.
Additionally, the Braaap MX-110F features a four-stroke engine with an adjustable suspension and a wider power range than the competition. It’s a good starting point for someone new to the world of motorcycle customization. Once your child has mastered the fundamentals of driving, switching to a clutch pedal is always a smart move.
The manual clutch provides more gears, and your child will love shifting gears manually as the vehicle speeds up or slows down. When your child gets the chance to ride a 250cc or larger bike in the future, this skill will come in handy.
How efficient is a 100cc dirt bike?
It’s a great time-saver. Despite their rarity in competition, 100ccs are an excellent training tool for individuals. The typical speed of a 100cc motorcycle is between 40 and 55 miles per hour. Over 100 mph has been admitted to by the professionals. At 55 mph, you’re travelling at about 88 kilometres per hour.
Having the ability to ride the bike at speeds of up to 60mph while yet being comfortable makes it a viable option. A more powerful model, such as the kx100, is an option if you have the extra cash lying about. A nice 100cc bike is significantly more pleasant for many customers than a 150cc cycle, according to those who have tried it out.
Because a 100cc motorcycle isn’t the smallest on the market, you may be confident in its performance. It’s easy to find a bike with an 80 or 50cc engine, and they’re all efficient. As a result, there’s no need to change your mind about buying a 100cc bike.
What’s The Difference Between 100CC and 50cc Bikes?
There are many differences between a 50cc and 100cc bike and some are listed below:
- The maximum speed limit:A 100cc motorcycle has a top speed of around 40-55mph. This is roughly 80 kilometres per hour (kph) when converted to kilometres per hour (kph). A 50cc dirt bike, on the other hand, has a top speed of 25-40 mph. In total, this works out to around 64-65 kph.
- Ease of control:A dirt bike’s rideability is directly related to the bike’s top speed. It’s completely safe to ride your bike at speeds between 25 and 40 mph without any worries or concerns whatsoever. As a result, riding a 50cc bike is more manageable than one powered by a 100cc, and vice versa. When compared to a more powerful bike, a 50cc bike is much easier to outpace.
- The Weight of the bike:Because of their smaller size, many 50cc motorcycles weigh less than a 100cc motorcycle. Because the two are so near together, it may be difficult to tell the difference.
Which One Is The Best 100cc Dirt Bike?
