There are always different classes and age groups.
MX nationals run 250cc men and women. There is also a 450 or "open" class.
The two main types of dirt bikes are motocross and trail bikes. Yamaha, Kawasaki, and Honda all make these types of dirt bikes.
depends on your age and height
no those bikes are not made for those kind of roads
just 2-stroke oil can get it at fix up stores, many places have it
All piston engines have a RPM range where they perform best, regardless of what kind of vehicle they're in.
That is kind of a tricky question. Dirt bikes encompass any bike that is ridden off road plus what are known as dual sport bikes. Most of the manufacturers categorize their dirt bikes as motocross or off road. Basically "dirt bikes" break down like this; 1) Motocross race bikes and woods race bikes. These are both liquid-cooled bikes with aluminum frames and racing suspension (compression and rebound settings, long travel, etc.), the woods race bikes just have some minor changes such as a wider gear ratio, a heavier fly wheel, bigger tank, lights, softer spring rate, etc. 2) Trail/play bikes. These bikes have air-cooled engines, steel frames and much less suspension than the race bikes. 3) Dual Sport bikes. This category is everything from Woods race bikes with a dual sport kit installed to make them street legal to production dual sport bikes such as the Honda XR650L and BMW 650GS.
it depends on what kind of bike...if your talking about a dirt bike you can get a silencer pipe from fmf that is much cheaper than a whole exhaust that will make it much quieter.
There is no such combination. Trials bikes are mountain bikes that one could construed as being "trick bikes" as trials require riders to "hop" around a complex obstacle course more than actually propelling the bicycle in a forward motion. I think he is refering "trick bike" to bmx? If so, the combination is a Dirt/street Mountain bike Check out some brands such as Dartmoor, NS, DMR, Black Market, Revell, Norco, Specialized 24seven, Identiti for info on there Dirt jump/street bikes (Dj)
well it matters wat kind of bike it is if it is one of those really nice motocross racing bikes then change the oil every time you go riding me i change it once every week so it does not hurt my valves or siez my engine.
Depending on your age I would start on a cr125 Honda. Honda is known for having very high quality bikes and can take a beating.
there were running races and boxing and many more .
