Honda released a motocross bike that resembled a weapon in 1972, setting up a frenzy as everyone scrambled to get one. There was nothing else like the CR250 Elsinore. The market leader was Honda…

What dirt bike model did Honda make first?
Honda unveiled the CR250M Elsinore, a motocross bike unlike any other, in 1973.
Everyone coveted this two-stroke motocross weapon. It had a polished metal tank, lots of midrange power, a narrow midsection, and amazing design. It was a sleek, light beauty. Its 214-pound weight and 7.1-inch fork travel were both state-of-the-art at the time.
When did Honda start making dirt bikes?
You probably spent the last 20 years or so working in a cave sorting mushrooms if the name Honda doesn’t immediately come to mind. Here in the US, in 1959, the real Honda story—the one that matters to us dirt bike freaks—began.
What is the oldest brand of dirt bikes?
One of the most established manufacturers of dirt bikes is Maico. Since the company’s first dirt bike rolled off the production line in Germany in 1926, business has been brisk. Midway through the 1950s, Maico started producing two-stroke scooters. In both the United States and Europe, the Maico Motocross and Maico Endura brands are regarded as some of the most well-known dirt bikes ever produced. The popularity of Maico dirt bikes is still strong today, and they are known for their excellent fuel efficiency, high-quality construction, and affordable prices. Maico has also constantly produced dirt bikes with great acceleration and speed, which never goes out of vogue. Today’s dirt bike enthusiasts value a quick ride just as much as their predecessors did.
When was the original four-stroke dirt bike released?
However, Yamaha made sure that motocross fans would only have to wait a short while. The YZ400F 4-stroke production motocrosser was debuted in June 1997, just three months after the factory bike had its racing debut.
Honda stopped producing XL when?
Honda’s four-stroke 250 cc (15 cu in) XL250 motorbike was first produced in 1972 and continued to be produced through the majority of the 1980s. It was the first mass-produced four-valve motorcycle and the first contemporary four-stroke enduro motorcycle when it initially appeared. (The Ricardo Triumph four-valve of the 1920s was the first four-valve single, while the Indian 8-valve V2 racer of 1911 was the first four-valve engine.)
The innovative large modern four-stroke-enduro wave was made possible by the XL250 and, later, the XL350.
The XL250 is a “enduro” or dual-sport bike, which means that while it physically resembles a dirt bike and exhibits many of its traits, it is street-legal and designed for both on- and off-road use. Since the bike has no hydraulics, it is entirely mechanically operated. At the wheel, the 250cc 4-stroke engine generates 24 horsepower. With oil, grease, and gasoline, the motorcycle weighs 288 lbs. The fuel tank holds 2.4 liters (9.5 litres). Collectors and hobbyists have continued to have a strong demand for this model. The XL250s models’ slim streamlining, which measured only 12 inches at its widest point, omitting the handlebars, was an intriguing finding.
There were not many changes made to the 1980 Xl250 throughout manufacture, however the rear chain tensioner was.
The distinctive 23-inch front wheel, rear dual shock, and 6-volt electrical system were only available on the 1981 XL250S model year. Additionally, it had attractive twin speedo and tacho gauges in the Australian and continental versions, as well as improved rear brakes in a larger hub and a reworked five plate clutch. In order to make the engine quieter, the balance shaft was changed from being chain-driven to gear-driven in 1982. A six-speed gearbox was also added, along with an automatic cam chain tensioner. Honda switched back to the 21-inch front wheel in 1982 and also debuted the 12-volt electrical system and Pro-Link rear single shock suspension. The short stroke version of the RFVC type engine and dual, progressively controlled carburetors (the left one opened 1/4 to 1/2 way before the right one opened and both achieved full throttle together) were features of the 1984–1987 vehicles.
For the USA, the XL250R and XL600R were discontinued in 1987. The short-lived NX250 series took the place of the XL series in 1988–1990. The XR250L and XR650L, which are street legal and closely resemble the XL series’ origins, were introduced by Honda in 1992.
The first KTM dirt bike was created when?
Hans Trunkenpolz founded the Austrian business in 1934 as a small repair shop in Mattighofen. Although the name Kraftfahrzeug Trunkenpolz Mattighofen was not registered, it was the name of his business. They were designated as the DKW motorcycles’ official supplier in 1937.
Due to its work repairing diesel engines for the military, the firm made it through the Second World War. When Hans received a call to active duty, his wife Elizabeth ran the company until 1943.
Few people could afford cars after the war, so Trunkenpolz began building his own motorcycles. The R100 was the first prototype, which was created in 1951.
With the exception of the engine, which was a 98cc Rotax made by Fichtel & Sachs, the most of the components were produced in-house.
Beginning with just three bikes per day and twenty staff, serial production began in 1953.
The company was renamed and registered as Kronreif & Trunkenpolz Mattighofen in 1953 after businessman and racing enthusiast Ernst Kronreif acquired a large stake. KTM is the initials of the two owners and the location of its origin.
In 1954, the Austrian 125cc was the first national championship won by a KTM motorcycle. KTM made its debut at the International Six Days Trials (or ISDT as it was known then) in 1956, where Egon Dornauer rode it to victory and a gold medal.
John Penton, an importer, initially imported the bikes to America in 1968 under the Penton brand.
What 2-stroke Honda model did Honda make last?
A Hondaracing dirt bike was the Honda CR250R. The prototype was constructed in 1971, but sales of the 1973 model “out of the box racers” to the general public did not start until late in 1972. The CR250’s final year of manufacturing was 2007, after almost 37 years of existence. [2]
Honda built an aluminum motocross motorcycle chassis in 1997, a first for the industry. These “first generation” steel frames were thick and robust, which marked a significant improvement over the earlier steel frames, whose early years had experienced flexibility as an issue. In an effort to prevent lean mixture preignition, the 1997-8 engines came with a redesigned stator that provided DC voltage for the new Keihin carburetor with an electronic “Power Jet” system. A rectifier/regulator and a capacitor were part of the new electrics. Although the Power Jet was no longer present, the 1999 model was nearly comparable.
The “second generation” aluminum frame for 2000 included smaller twin-spars, which reduced stiffness and improved handling. Older PJ versions were replaced by the Keihin PWK carburetor. The CDI box has an 8000 RPM cap. With the exception of a redesigned CDI box that increased the redline by 500 RPM and added two more horsepower, the 2001 model was essentially unchanged. Weather variations caused the new Mikuni TMX carburetor to behave temperamentally.
Honda ended the exceptional interchangeability that had existed from 1992 to 2001 for 2002.
A brand-new engine was introduced, replacing the centrifugally operated exhaust valve system in use since 1992 with an electronically controlled, cable-operated RC valve and switching from cylinder to engine case reed induction. The carburetor now has a TPS (Throttle Position Sensor), which is powered by a new stator. There was no ping sensor anywhere, but the ECM would now be able to delay the ignition timing to prevent preignition.
A third and final generation of the CR250 aluminum chassis, which was thinner and had superior flex characteristics, also debuted. Up until the end of this 2-stroke’s manufacture in 2007, the engine and chassis remained the same with just minor suspension and plastics modifications. The case reed engine may have the best design, but Honda never fully exploited it since four stroke engine development quickly captured the industry’s focus. The aftermarket was a necessity for many owners of the final generation of the CR250 in order to maximize that engine’s performance. The 2001 variants of the CR250, which are regarded as the greatest of the best ever made, are still enjoyed by fans.

What is the world’s rarest dirt bike?
In the US, dirt motorcycles are utilized for a variety of activities. People adore dirt motorcycles because they are light, simple to use, and can be used for a variety of activities, from racing to having fun in the dunes. Dirt motorcycles are highly adaptable as a toy for having fun with because anyone can ride them, from very little toddlers to enormous adults.
The 1968 Suzuki TM250 is the most uncommon dirt bike in existence. If you’re a fan of vintage dirt bikes, you’re in luck because just 65 of these bikes were shipped to the US in the first shipment. Due to the relatively low production numbers for the initial sales, obtaining this bike can be exceedingly challenging.

What exactly does KTM mean?
The company’s preference for using initials for model names is not surprising given that its name, KTM—Kronreif & Trunkenpolz Mattighofen—stands for Kronreif & Trunkenpolz Mattighofen. It would be simple to claim that street bikes have traditional names, whereas dirt bikes have letter model names. You’ll soon realize that it’s not quite that easy. The Enduro portfolio doesn’t even include the Enduro R variant. Additionally, special editions may deviate from the naming scheme, but let’s save that discussion for another time. Even if we are unable to simplify the KTM alphabet soup, we will try our best to explain it.
Why did two-stroke racing end?
Because they were unable to adhere to the increasingly stringent EPA rules for automobile exhaust emissions, two-stroke engines were forced off the market. The simplicity of having only three moving parts—the crankshaft, con-rod, and piston—which made two-stroke engines appealing, was also its downfall.
