Suzuki’s New QuadSport Z90
- Updated: March 9, 2007
Suzuki made junior’s new QuadSport Z90 looks just like dad’s LT-R450 QuadRacer. Suzuki’s all-new entry-level 2007 QuadSport LT-Z90 wears aggressive LT-R inspired graphics on all new LT-R inspired flared fenders in two stunning color choices, white or Suzuki yellow. The QuadSport Z90 also comes standard with an electric start and a recoil start back up plus full floorboards and a T-shaped seat. The QuadSport Z90 is sized for smaller riders and it’s appropriate for adult-supervised children 12 and older. A four-stroke, forced-air-cooled single-cylinder engine powers the QuadSport Z90 and features an easy-to-use CVT automatic transmission that requires no clutching or shifting. Suspension is of the single A-arm front and single-shock rear variety, and can tough it out over a variety of terrain. Large 19-inch tires give the ATV an aggressive look, yet a built-in throttle-limiter system keeps every ride under control. Additionally, the high-mount snorkel-type air intake keeps things dry if a water crossing is in its path. The QuadSport Z90 is the perfect machine for entry-level riders to experience the exciting world of Suzuki ATVs for the very first time
