KTM Sportmotorcycle AG is an Austrian motorcycle manufacturer. The company was founded in 1934 by engineer Hans Trunkenpolz in Mattighofen. It started out as a metalworking shop and was named Kraftfahrzeuge Trunkenpolz Mattighofen. In 1954 KTM began producing motorcycles.
KTM is most commonly known for its off road motorcycles though in recent years it has expanded into street motorcycle production.
The company was founded in 1934 by engineer Hans Trunkenpolz in Mattighofen. It started out as a metalworking shop and was named Kraftfahrzeug Trunkenpolz Mattighofen. It wasn't until 1953 that KTM began production of motorcycles. With just 20 employees, motorcycles were built at the rate of three per day. In 1955, a businessman Ernst Kronreif became shareholder of the company, on acquiring a sizable portion of the company. It was then renamed Kronreif & Trunkenpolz Mattighofen. Trunkenpolz died unexpectedly in 1989. During these early years of motocycle production at KTM, almost all components for the motorcycles were built in-house by KTM.
Throughout KTM's history, they have been on the leading edge of motorcycle technology. They were the first manufacturer to produce a liquid-cooled four-stroke motorcycle engine for an off road motorcycle, a design which has since been replicated by all other manufacturers (KTM even supplied radiators to Suzuki in their early water-cooling days. In 1986, KTM became the first motorcycle manufacturer to include both front and rear disc brakes on an off road motorcycle. In 1998, they offered a linkless rear suspension, dramatically reducing the un-sprung weight of the bike (KTM was the first major manufacturer to do so, although ATK, a small market, niche brand did so as early as 1987). They were also the first to offer hydraulic clutch mechanisms on all models of motorcycles, and were the first to offer a competition-ready supermoto bike.
The term off-road refers to a driving surface that is not conventionally paved. This is a rough surface, often created naturally, such as sand, gravel, a river, mud or snow. This type of terrain can sometimes only be travelled on with vehicles designed for off-road driving (such as SUVs, ATVs, snowmobiles or mountain bikes) or vehicles that have off-road equipment. The KTM is well equipped for these environments and is popular among many off-road riders. The design of this motorcycle is well suited to this sport and the weight of the motorcycle is another advantage. KTMs come stock ready to race, with a hydraulic clutch, full adjustable WP front and rear suspension and powerful engines requiring no modifications prior to racing. The KTM has won every Dakar Rally since 2001.
Motocross - The 2008 SX line includes 65, 85, 105, 125, 144 and 250 cc two-stroke models, and 250, 450 and 505 four-stroke models. In 2005 KTM released the new 250SX-F to the general public. For the 2007 model-year, all of KTM's four-stroke SX motors were re-designed similarly to the 250 SX-F, in a dual-overhead cam 4-valve line dubbed the "RC4". The SX-F's are KTM's new racing motocross range introduced in 2007.
KTM now produce a 150SX (144 cc), which was developed to take advantage of AMA (American Motorcyclist Association) rule changes in the amateur classes. KTM and TM are the only manufacturers to develop a 144cc motorcycle.
Cross-Country The XC line includes 65, 85, 105, 200, 250 and 300 two-strokes, and 250, 450 and 505 four-stroke models. The XC line updates and replaces their old MXC bikes. They feature a close-ratio gearbox, stiffer suspensions, and the four-strokes have a shorter-stroke design, mimicking their SX line. In 2007, they introduced the 250XC-F which is based on the 2006 SX model.
KTM's XC-W offroad bikes are 200, 250 and 300 two-strokes, and 250, 400, 450 and 530 (actually 510cc) four-strokes. They feature plusher suspension and a wider-ratio transmission than their XC line counterparts. The XC-W replaced their old EXC two-strokes, a move the company made in order to comply with EPA restrictions in the United States. Two-strokes are still designated as EXCs in Europe markets.
Enduro The 2009 EXC line consists of 250, 450, 530 (actually 510 cc) four-strokes, and 125, 200, 250 and 300 cc two strokes. The EXC line has been a long-time favourite for Enduro market, and outsell other larger-volume brands to Enduro racers. The RFS motor (2000-2007) was replaced with the XC4 motor for the 2008 model year.
Super Enduro consist of 690 cc and 950 cc machines, mix between an enduro and a trail bike.
Supermoto KTM produces several supermoto race bikes with displacements ranging from 450 (a supermoto version of the 450sx-f) to 565 cc. They also make four non race-oriented models in 625, 654, 950 and 990 cc displacements. KTM was the first manufacturer to offer a competition-ready Supermoto bike to the public, and their sponsored racers currently sit atop the US Supermoto racing circuit. The new LC8 SuperMoto 950 has received rave reviews from all the bike magazines and newspapers in the United Kingdom.
Dual-sport Adventure bikes offered with both the LC4 Engine (Adventure 640, 640R) and the LC8 Engine (Adventure 950, 950S, 990), the 640R is the base of the Rally 660 which has won many Dakar Rallies.
