Supercross

No. Different mounts, and usually a manufacturer will only make an engine that fits only bikes in a certain range of years, like 2001-2004.

No. According to the FMF website, the 99 and 04 YZ125 have different part numbers.

Obviously yz125 is more faster than yz85.

In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc

Evel made his first jump in 1965. Evel was 27, and had became co-owner of a motorcycle shop in Moses Lake, Wash. To attract customers, he announced he would jump his motorcycle 40 feet over parked cars and a box of rattlesnakes and continue on past a mountain lion tethered at the other end. Before 1,000 people, he did the stunt as promised but failed to fly far enough; his bike came down on the rattlesnakes. The audience was in awe. “Right then,” he said, “I knew I could draw a big crowd by jumping over weird stuff.”

Supercross= usually races inside stadiums, unless it takes place at a speedway, like at the Daytona supercross. Supercross utilizes a single race format, meaning one final moto. To get to this final moto, the riders must qualify through a series of heat races. Supercross is fast, tight and technical. They have big jumps and rythem sections. Supercross usually races on Saturday nights...

Motocross= Motocross races are held on tracks that are permanent, meaning, it isn't torn down after every race, like a supercross track is. The track is longer, wider, and most of them have natural terrain. A lot of outdoor tracks have hills and tricky sections, like sand or off camber corners. They have some big jumps. Motocross uses a 2 moto format. Like supercross, a rider must qualify through a series of heat races.

Like I said before the motocross series uses a 2 moto format. The winner is determined with the best overall score.

Motocross races are usually held on Sunday afternoons....

I believe this was Cary Hart, however he did not successfully land both wheels. Still, at this point, everyone knew that it was now possible to land one. A major step forward for freestyle motocross.

Many people think it's showy, vulgar, 'brash and brassy' to flash their money around.

Arenacross tracks are smaller than Supercross tracks. Supercross events are usually held on baseball fields, and Arenacross tracks are usually held on basketball courts.

Scientists and engineers have puzzled over this phenomenon for many years, but only recently did a group of scientists (Stephen W. Morris of the University of Toronto and Nicolas Taberlet and Jim N. McElwaine of the University of Cambridge) actually perform controlled studies on how washboarding forms. The result of their studies showed that even with the most regular of dirt/sand surfaces, there are irregularities in the road that cause the wheel to bump. As the wheel rises, it pushes some of the road grains ahead of itself, creating a small ridge. After the bump, the wheel strikes the road surface just a little harder than normal, causing the dirt/gravel to shift forward, creating a little dip and pushing some of the grit into new ridges, which the wheel then has to rise over--which causes the next bump, etc. etc. It doesn't take many passes by vehicles to get a long row of ridges, and your washboard is born. It isn't just hills, but curves, straight sections or any part of any kind of dirt road. There's nothing that can be done about this, except call the graders and smooth the road out again. And keep your shocks in good repair!
