The Suzuki LT250R was a sport ATV manufactured between 1985 and 1992. It combined a lightweight frame and good handling, with a 249cc liquid cooled two stroke engine. Commonly known as the Quadracer, it revolutionized the (ATV industry). Before this model was released, the ATV world was dominated by three-wheelers. Although the four-stroke LT250E Quadrunner was released a year earlier, it was not well accepted by racing enthusiasts that were hesitant to adopt the heavier four-wheelers over their three-wheelers. Then came the LT250R. Most of the advances made by Suzuki with this quad have been overshadowed by the Honda TRX250R, which was released in 1986. During these early years though, they were treated as equals, with the Honda being preferred by most because of its apparent handling characteristics. Even though both model names ended with "250R", the Honda walked away with the nickname. The LT250R setup is what is commonly used in today's sport quads, such as: 2-wheel rear drive with a solid axle "A-Arm" front suspension Powerful lightweight engine Manual transmission and clutch Hydraulic disc brakes, two in front, one for the rear Chain drive 1985 In an apparent attention to weight by engineers, it came with many aluminum parts: swing arm, rear axle carrier, engine cases, front spindles, rear shock link. But the overall advantage in weight (compared to most other quads) is the simplicity of design. The '85 and '86 Quadracers are known as the lightest production full size race quads ever built, tipping the scales at only 293 lbs dry making them similar to the 250cc two stroke race three wheelers of that era. (They were actually lighter than the Yamaha Tri-Z, slightly heavier than the Kawasaki Tecate 3, and identical in weight to the Honda ATC250R.) In 85 the Suzuki LT250R QuadRacer became the first high-performance four-wheeler 1986 Mostly the same as 1985 but with a Mikuni VM34SS carburetor. It also had a very slight modification to the decals, and had white letters on the seat spelling "Suzuki" instead of yellow letters used in '85. 1987 "The beaner year", many different changes occurred within this production year, sometimes making parts hard to match up. The major changes were in the frame, engine, swingarm, and a-arms. The most visible change is in the frame right in front of the cylinder the 85-86 frame has a single down bar, but the '87+ has a single wishbone down-tube.
