The army had motorcycles in the 30's and off the clock the men would race in the fields so i'd call that dirt biking.

Bob haro invented the first freestyle BMX bike.

No, the magneto provides the voltage for the spark.

The Yamaha EF 600 generator has a four stroke engine and uses gasoline with no oil added to the fuel. It will run for about six hours on one fill of the gas tank, about 0.5 gallon (US).

Depends on maintenance, Kawi will go faster longer without maintenance.

Also depends on which bikes you are comparing, but follow the link below for the MXA 2010 450 shootout.

a Honda takes premix and can take 4 strike motor oil for tranny oil

60-65 tops with stock gearing, a motocross bike is not about top speed but how quick and how well it handles.

Loosen off the back wheel or adjuster if it has one then you put the master through the two ends of the chain and put the outer link piece on the pin sticking out and then put the slide clip on.

alot of motocross racers (like me) can get hurt from not wearing the back of their chest protecters and get landed on or stabed in the back with a footpeg. Believe me it HURTS!!!!!!!!!!!!!!!!!!!!!! Equipment is extremely important, there would be alot less injuries if people who ride, (not just motocross) wear the right equipment. You have to make a decision how important you/your body is and how much you enjoy riding, its hard to enjoy riding if you have a broken leg, arm, ankle, wrist, etc., having the right equipment can save you from many injuries even death. Start with the best Helmet money can buy, good goggles, get the new Hahns device for the neck, (they're like the Nascar drivers wear, only for motorcycle racers) and yes a chest protector, front and back, a good jersey, motocross pants with shin & knee guards, good gloves, and the best motocross boots you can get. As far as how many get hurt riding motocross, the number keeps rising, to many to count. I was in a race where a fellow racer bought a cheap 3/4 face helmet from a department store, he fell after a jump and the bike behind him couldn't miss him, that was my first experience with a tragedy at a motocross race. "Wear all the proper/best equipment you can get"In a nut shell to many. Come on get smart ware gear I have a broken arm and leg because of it. I

between 60 - 75%. Depends on how much weight is biased toward the front wheel and how much brake pressure is applied.

You can put a Baja Designs headlight kit on it but it will require a stator to power the light first.

The correct mixture is 50:1, or one pint 2 cycle oil to six gallons fuel.

monster energy, rockstar energy, fmf , and many local motorsport shops sponsor people to

Depends on how it is geared.

Stock gearing out of crate approx 72 mph

This will be known to those people who are interested in motorsports: Fédération Internationale de Motocyclisme.

Two-stroke engines usually do not have an internal lubrication system; the moving parts are lubricated by a small flow of lubricating oil which enters the combustion chamber pre-mixed with the fuel. This oil is usually not completely burned during the power stroke, and therefore a portion of it clings to the cylinder walls, passes into the crankcase, and eventually reaches all moving parts of the engine.

Not too sure, but if it has a fill screw just take it out and start filling it up until it starts to run out of the hole and then replace the screw. i think not 100% sure

Not likely, ttr 125s are 4 stroke and it is a trail bike. a yz 125 is a 2 stroke race bike. yz 125s are worth more unless you trade for a older model then the ttr. its posable but highly unlikely
