The '''[[ATK]] 250''' was a liquid-cooled, two-stroke, Rotax single cylinder Enduro [[motorcycle]] produced by [[ATK]] in 2003. | |||
==Engine== | |||
A 68.6mm [[bore]] x 68.6mm [[stroke]] result in a [[displacement]] of just 249.0 cubic centimeters. | |||
==Drive== | |||
The bike has a 6-speed, manual transmission. Power was moderated via the wet multi-disc, manual. | |||
==Chassis== | |||
It came with a 80/100-21 front [[tire]] and a 100/100-18 rear tire. Stopping was achieved via single 260mm disc, 2-piston caliper in the front and a single 220mm disc, 1-piston caliper in the rear. The front suspension was a 46mm Paioli telescopic fork while the rear was equipped with a [[Ohlins]] adjustable monoshock. The wheelbase was 58.5 inches (1486 mm) long. | |||
==Overview | |||
The introduction of [[ATK]]'s [[liquid cooled]] models in 1995 generated considerable interest for the US's only dirt bike manufacturer. Initial reports said the water pumper motor was a rocket ship, a worthy compromise to ATK's long term commitment to building simple, reliable, easy-to-maintain (yet slow) [[motorcycles]]. We soon discovered that the motor performance, as well as the entire bike, are quite the dichotomy, coupling innovative features that foster excellent performance with other traits that leave you wondering why. | The introduction of [[ATK]]'s [[liquid cooled]] models in 1995 generated considerable interest for the US's only dirt bike manufacturer.

Not surprisingly, this has led to vastly divergent impressions of the overall package, as the ATK has generally not faired well in the press. This dichotomy, coupled with the inherent peculiarities of the no-linkage chassis, served to increase time and effort needed to get things dialed in. It took longer than usual to properly set up the 260LQ. That's perhaps why, at least in part, all of the other tests or reviews panned it unmercifully. Truth is, our first couple of rides on the 260 weren't much different. Stiff suspension action and questionable power had us wondering what we had got ourselves into. However, rather than whining and shoving the LQ into a dusty corner, we gave it a chance, taking the time to figure things out and dial it in proper, the end result being a competitive, raceable mount with a distinctly different performance envelope. In the case of this ATK260, patience truly is a virtue. | Not surprisingly, this has led to vastly divergent impressions of the overall package, as the ATK has generally not faired well in the press.
