both because with a horse it would depend that if it has been trained like for a race but on a average horse then a dirt bike if faster but see with a dirt bike it depends on the type of engine it has because if the engine is beat up the yes 100% would the horse beat it but if it was a good engine the yes the dirt bike would win but on average it would probably turn out to be the dirt bike would win.
a racing 2stroke dirt bike
The 80 is faster and better no questions asked!
motor cross is faster
Two strokes can accelerate faster but it depends on engine size
According to my calculations a go cart is not faster than a dirt bike. Ive had my experiences.

a bike downhill horse uphill
dirtbikes are faster, atvs have a lot more weight that the engine has to pull. Dirt bikes are way faster.

A 70 cc Baja dirt bike can be made faster by installing bolt-on engine options. The intake and exhaust systems are the most basic upgrades and can quickly raise power making the bike faster.
