2008 X4R 160cc w/ Marzocchi Forks
We set a standard in 2007 with the introduction of X4R that came equipped with the Italian build
Marzocchi Shiver forks but that was not enough for us. After a year of riding and racing these
bikes we’ve made a great bike even better with a new GPX Moto powerplant, high volume oil
cooler and race tuned suspension. The 2008 X4R now comes with a GPX Moto 160cc four
stroke, equipped with a close ratio, four speed transmission, Manuel clutch and 26 mm carburetor.
With the added power, we knew people would need more traction and better handling, so we
choose new aggressive front tire and fine tuned the rear shock for even more adjustment to
maximize control under the toughest of conditions.
