 Starting in 1997, Honda started the first gen aluminum frames. The first gen frames were thick, rigid and were a big change from the previous steel frames. Then in 2000, Honda came out with the second gen aluminum frame, which was less rigid. It also had a smaller and thinner twin-spar aluminum frame. Which provided the rigidity decrease. That made for better handling. Then in 2002, they came out with the third gen aluminum frame. Which was thinner, and lighter. The prototype was built in 1971, but it was not until late 1972 that production of out of the box racers began. It was made available for sale to the general public in 1973. The CR250 was produced for nearly 37 years, 2007 being the final year of production.

The name pit bike originated from the use of a Honda Z50. The ride around the pit areas of dirt bike races and race events across the United States. The fairly cheap price and the mobility of these bikes made them easy to use. When at racing events. Popular dirt bike movies like the 2001 Crusty Demons of Dirt 3 show. How these small motorcycles can be used to do things other than just riding back and forth in the pits. A part of this movie shows people taking huge bicycle jumps on a Z50 in someone’s back yard.

Motocross was first evolved in the U.K. from motorcycle trials competitions. Such as the Auto-Cycle Clubs's first quarterly trial in 1909 and the Scottish Six Days Trial that began in 1912. When delicate balancing and strict scoring of trials were dispensed with in favour of a race to be the fastest rider to the finish. It was called scrambles, said to have originated in the phrase, "a rare old scramble" describing one such early race.Originally known as scrambles racing in the United Kingdom, as the sport grew in popularity, the competitions became known internationally as motocross racing, by combining the French word for motorcycle,motocyclette, or moto for short.

Following the dissolution of Czechoslovakia and the dismantling of the communist bloc. the Jawa consumer motorcycles and the Speedway competition bikes were divided into separate companies. In the nineties.  JAWA Speedway bikes were successful. while the Jawa company has struggled. As of 2006 the JAWA mostly produce bikes similar to Honda 250 cc. 125 cc and 50 cc motorcycles and large bike with a 650 cc rotax engine.the iconic  two-stroke twin motor.

They kept the same frame with minor suspension changes until they stopped production of any 2-stroke in 2007.

Lots of people have different taste in dirt bikes but my favorite dirt bike would have to be a KTM 300 2 stroke. To this day. the KTM 300 is considered the best bike for racing. And riding on tight trials.  Two-stroke or four-stroke. It got a significant update in 2004. But even the ones made between 2000 and 2003 were pretty good. The two versions were the EXC and the MXC. The latter of which had more desert-oriented gearing. I have always wanted to own a ktm. Those bikes are awesome if i could pick out one bike i would take a 250 2 stroke ktm.

The Yamaha YZ250F is a  motorcycle first released in 2001 by yamaha It has a five-valve. 4 stroke motor instead of a 2 stroke and initially had a steel frame and an aluminum subframe. which was replaced in the 2005 model with an all-aluminum frame. From 1974 through 1982 the engine sported a 70 mm bore and a 64 mm stroke. That will produce a displacement of 250 cc. In 1983, the bore was reduced to 68 mm and the stroke was increased to 68 mm producing a displacement of 247 cc. This is one of my favorite bikes of all time. They are super fast but still really good for trail riding and things like that. This bike might be older but it will keep up with the newer bikes that are in the same cc class. I would love to buy one of these i would probably get rid of my cr for it.
