LOTS OF POWER WITH LOW MILES!! A Mono-Shocking New Development. The first shot fired in the four-stroke revolution is back and badder than ever, 30 pounds lighter and with a new, plush ride courtesy of its all-new, industry-exclusive Mono-Shock RA (remote adjust) rear suspension. It sure feels like rocket science from the saddle. And it rides almost weightlessly, too, thanks to a new 20-position clicker shock out back that has a setting for any situation. The result of years of testing by Yamaha engineers, the RX-1 has no equal on the trail, thanks to a 145-horsepower class four-stroke four-cylinder engine. All that power surges through a chassis filled with lightweight components a new titanium exhaust system, new magnesium engine covers, aluminum A-arms while you enjoy the kind of acceleration that can only come from a four-stroke powerband acceleration thatll make your heart skip a beat, speed thatll curl your toes. Harnessing all of this power wouldnt be possible without the superior handling of the RX-1. This sled is so well balanced that you hardly know youre rounding a corner, whether its flat and smooth or full of pesky stutter bumps. Enhanced comfort is provided this year via a taller, thicker seat and higher handlebars. Estimated dealer arrival from July 2004
