yes
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.
a racing 2stroke dirt bike
The 80 is faster and better no questions asked!
metal - duhhh.....
A slip on exhaust will give a dirt bike more power. A full exhaust setup will give you even more power than a slip on.
motor cross is faster
According to my calculations a go cart is not faster than a dirt bike. Ive had my experiences.
Two strokes can accelerate faster but it depends on engine size
yes. you mean is a race bike faster then a trail bike. ya all racebikes are faster
an exaust pipe causes compression to form more in the cylender which makes the bike go faster. if you didnt have a pipe on your bike, don't count on going anywhere. but it is possible to ride a dirt bike without a pipe, it just wont pressurize enough so your bike would break shortly
It could be condensation from hot exhaust gases on the cool exhaust pipe.
