CR125[edit]

Honda CR125M Elsinore

Honda started to build the CR125M in 1973. Honda called it the “20 Horsepower Feather”. It sold for a stunning $749 [1]. It was equipped with a 2 stroke 123cc air cooled motor that had a top speed of 60mph.[2] It was really a sub-par attempt at building a dirt bike. Just like the CR250R in 1981 the CR125 also took a step back. It was really heavy and slow, and had a horrible single shock. In 1985 was when the CR125 got the Showa suspension and had more problems because it was the new technology. They had not perfected the technology they put into the bike and had many problems with parts and operation. Honda was somewhat ahead of themselves when it came to technology and that really hurt Honda for a couple years. Honda was struggling with the new technology which hurt them at the time because the other companies had perfected the old school technology. 1988 and 1989 were the two years that the technology came together and everything really clicked for the CR125.


CR250[edit]

Honda CR250M Elsinore

1973 was the year the CR250M Elsinore had been launched. This 2-stroke was one of the first of its class, and set the bar high for 2-stroke motorcycle development. In 1974 and 75 the CR250M didn’t change much. Which gave the upper hand to Suzuki and Yamaha which let them design and develop better dirt bikes than Honda. In 1978 Honda released its newer version of the CR250M. They renamed the bike the CR205R. The “R” in the name stood for Race [3] . The fire engine red bike was a real eye opener. This was what everybody remembered about the CR250R this year. When 1981 came around Honda was trying to put better technology into their bike, They wanted to put new suspension on the bike but didn’t know much about the new technology. They went with the new suspension and had numerous problems. The suspension didn’t work correctly at all and the bike had reliability issues. They tried to put too much technology into the bike and it turned out to haunt them. This year was a huge let down for Honda. They let their other competitors catch up to them. 1984 was really the next big year for Honda and the CR250R. This was when the bike caught up to the technology that had been put in in 1981. They did add new features such as a hydraulic front disc brake, and a new exhaust valve [4]. All the way up to 1990 the CR250R had virtually stayed the same except for a couple little changes such as hydraulic rear brake, Showa front suspension, and a bigger carburetor. 1992 was when the CR250R took on a newer more aggressive look but had some downfalls. One of the biggest downfalls was the amount of power the new engines were producing and the weak steel frame. This was bad news for Honda. Many riders told Honda to change the frame to something stronger. But successful riders who were sponsored by Honda such as Jeremy Mcgrath had preferred the old stiff weak frame. 1997 was when the aluminum frame was introduced. Many racers liked this frame but casual desert riders weren’t buying the bike. So Honda had to go back to the development department and rethink the CR250R. The year 2000 was the year that Honda perfected the aluminum frame. It was it. It only got better from here. In 2003 the only real change that was made was the electronic power valve. The Honda CR250 has a carbuerated 249cc liquid cooled single cylinder engine that makes about 45 HP.[5] It has a five speed transmission with Showa suspension and a 2 gallon fuel tank.[6] In 2007 Honda said they will produce no more 2-strokes after that year.


CR500[edit]

1984 was the first year the CR500 was produced. It was nicknamed the “Ping King”. The CR500 had a 491cc liquid cooled 2 stroke engine that could make 55 HP, the most powerful motorcycle that Honda had ever produced [7]. It was a 2-stroke design. Since the CR500 was such a big bore bike it was hard to kick start it. The manufacturers started to jet the bike really rich in order to make it easier for people to start. The CR500 was an absolute monster. The only problem with it was it was terribly hard to ride because of the uncontrollable power it produced. The CR500 was also used for long desert races like the Baja 500 and the Baja 1000. The CR500 was discontinued in 2001. Many people believe that the CR500 was discontinued because of the CRF450 four stroke. Honda sold the CRF450 four stroke very well. It could have very well been the bike that put the CR500 out of production. The CRF450 was much lighter than the CR500 and the power band on the four stroke motorcycles was much better. The CR500 is still a highly sought after motorcycle because it is a piece of history as well as an incredible piece of technology.
