For 2020 we have TONS of quality options to choose from when it comes to picking an adult dirt bike. But when it comes to choosing the best adult dirt bike for you we need to break it down a bit more.
What defines an adult dirt bike?
Is it the size of the motor? Nope.
Is it a 2 stroke or a 4 stroke. Nope.
Really what comes down to is the seat height. Having a proper seat height for how tall you are is actually more important then most people realize.
Yes, can an adult ride a dirt bike that is too small for them? Yes, but it actually isn’t very safe as it ruins the balance of the dirt bike.
Why you ask?
Dirt bikes are designed for the rider to be in the stand-up attack position. When you are too big for the bike you run this balance.
Now, let’s get to talking about the best dirt bikes for adults in 2020.
You can ride a dirt bike in many different situations, this means the dirt bike manufactures have built specific adult dirt bikes for specific riding times. You have adult motocross dirt bikes, Enduro dirt bikes, trail riding dirt bikes, and cross country dirt bikes.

What's a good size dirt bike for adults?
If you have some experience in riding dirt bikes and you are of average height and weight then a good sized dirt bike would be something like 2021 KTM 250 XC TPI, 2021 Beta 250 RR Race Edition or Yamaha YZ 250 FX. Choose 250cc dirt bike as they are fun to drive for any average sized person.
Should I buy a 250 or 450 dirt bike?
A beginner to advanced dirt bike rider should choose 250cc engine for their dirt bike. 250cc dirt bikes are fun to drive and can ride through all trails. In contrast, 450cc dirt bikes are more for professional riders who can use the power of the engine for quick start, race or to pass obstacles easily.
What do I need to know before buying a dirt bike?
If you are buying a new dirt bike, a 250cc dirt bike from any major dirt bike brand has enough power for all trails but it is not too powerful. Test one at dealership for your size. If you are buying a used dirt bike you need to check engine & oil, tires, wheels, suspensions and linkage.
