ATK is an off-road motorcycle manufacturer in Utah, USA,
founded by an Austrian engineer, Horst Leitner, in 1980. The name "ATK" is
the abbreviation of the device which Leitner patented in order to eliminate
chain torque for a better handling. The device was called Anti Tension
Kettenantreib, from the German "chain drive". Horst Leitner, the former
500GP racer, is well known as he designed the ATK 560, ATK 640, ATK 407 in
the 80's and the Horst link design, considered an important suspension
system, at the beginning of the 90's. The Horst Link is a set of rear pivots
located on the chain stay just below and in front of the rear drop-out. {ad}
Horst sold ATK in the 90's and started AMP Research, which was the official
supplier of car, truck and accessory products to original equipment
manufacturers as Ford, Nissan, Mazda, Mitsubishi or Subaruso. This
suspension design element was found on Horst's line of AMP bikes. In the
late 90’s, the engineer sold the Horst link to Specialized Bicycles.
450 XC, one of the ATK bikes, has a 446cc engine which develops 46 HP at
11500 rpm. Released in 2006, it has fuel injection and electric start,
Öhlins suspensions and off-road tires. The bike is not heavy at all, with
only 242 lbs with only 2.6 gallons of fuel in the tank.
Just like its close relative, the 450XC, the MX version has a 446cc, liquid
cooled, single cylinder engine which unleashes 46HP at 11500 rpm. ATK
company dressed it up with Öhlins suspension, electric start and aluminium
twin spare frame.
After the ATK 700 appeared a lot of trial addicted bikers considered that
the XR650R from Honda is no longer the baddest dirt bike in the world. The
XR650R has won every Baja 1000, 500 and San Felipe 250 it has ever entered.
In 2003, ATK purchased the remaining inventory of Cannondale Motorsports,
which made it possible to add ATVs to their product line. A year later, ATK
took first place in the Grand National Cross Country Championship and two
Canadian National championships.
Currently, ATK is the only remaining off-road motorcycle manufacturer in the
United States.
Throughout its history ATK has enjoyed a tremendous
winning tradition. From desert racing to the dirt track ATK finishes first
at the finish line. A reputation of winning follows ATK not only in racing
but also in ground breaking product innovation. Technology firsts, such as
ATK's namesake - the anti-tension kutentraub,
side mounted shocks, linkless suspension, the first fuel-injected offroad
motorcycle, and the first production motard have all moved the industry
forward.
ATK's pace setting quality standards in engineering and manufacturing build
reliability into every vehicle. In 2003 ATK purchased the remaining
inventory of Cannondale Motorsports. This purchase added ATV's to the ATK
product line. For over two years ATK has refined and evolved the Cannondale
platform. In 2004 ATK took first place in the Grand National Cross Country
Championship and two Canadian National championships. The winning tradition
continues.
As the only remaining off-road motorcycle manufacturer in the United States,
ATK is still proud to put
"Made in the U.S.A." on our vehicles.
