Quadzilla???

For verification, the one known as "Quadzilla" is the Suzuki LT500, right? What is the main differences between this and the LT 250 (other than cc's)? I found a 500 for sale for a reasonable price (i think), but what im worried about is finding parts and the price of these parts. If anyone has any info whatsoever please fill me in. Also any sites, sources, etc. on these machines would be great too.

Ok folks, ive been researching this, and i feel stupid.Mainly what im wondering now is, how easy is it to find parts (and where?) and how expensive are they to hop-up/ maintain? Also what is the easiest way to tell the year on the Suzuki's, if this guy is not sure what year it is?

[TrengaBlaster3]

the "quadzilla" is the 500 and the "quad racer" is the 250.

[Juggalo]

actually their both quad racers. parts can be found for them but not as easy as say a 250r

[Leo]

The LT500 is physically much larger..

If memory serves they were pretty good machines, but they had occasional headgasket problems..

Oh yea, they are quite fast

Here are some specs on the lt500 and lt250






Quadzilla Details & Specifications



The Suzuki LT500R "QuadRacer" is more commonly known as "Quadzilla" in the ATV community. It is the big brother to the smaller LT250R "QuadRacer". Both QuadRacer models share similar design features adapted to high-performance racing conditions and they each sport the same yellow and blue color scheme, but share very few components which are not interchangeable. The easiest way to differentiate these two models from a far is by identifying each QuadRacer's blue, radiator grille. The LT500R's grille features a single vertical vane through the center, while the LT250R's grille features two vanes that are oriented horizontally.

The Quadzilla was offered only during the 1987 through 1990 model years. This fact makes it difficult to acquire a Quadzilla from the used market, and very difficult to find one in new condition. The 1987 Quadzilla product was known as the "H" model, 1988 was "J", 1989 was "K", and in 1990 it was "L". For example, sometimes you will see a 1989 Quadzilla identified as an LT500RK. The 1987 "H" model appears
to have been sold in greater quantities than each following model year. This observation is ironic due to the fact that the 1987 model had a different powerplant than all of the following years. The 1988 "J" model featured the second-generation Quadzilla powerplant. This new engine appears to follow the same general specifications as its predecessor, however proof that it is different lies in the fact that components are not
interchangeable and transmission gear ratios are different. In 1989, the "K" model received some chassis refinements. These refinements' presence can be easily identified by white-colored A-arm front suspension, replacing the former silver-colored A-arms of previous years. In 1990, the "L" model received even fewer changes. I suspect the changes in 1990 were in response to manufacturing cost considerations.

The rear shock (damper) is manufactured to Suzuki specifications by Showa. This Showa damper used in the Quadzilla was found on Suzuki's RM line of MX bikes in as early as 1984. While the rear damper is rebuildable, the front dampers are not. Although the front dampers are not rebuildable, it is still possible to modify them to perform differently.

The Quadzilla remains, to this day, Suzuki's largest-displacement and greatest-powered ATV. A new Suzuki ATV model, not to be confused with the Quadzilla, was introduced in 1997. It is identified as the "LT-F500". This new ATV is not a member of the QuadRacer family, has a smaller engine displacement figure, and far less horsepower than the Quadzilla does.

High-performance, liquid-cooled, reed-valve, two-stroke engine

Suzuki LT250R Details & Specifications

In the middle 1980s, Suzuki had different ideas of what an ATV should be. Other motorcycle manufacturers had already produced ATVs in the form of three wheelers for a number of years and now had progressed to a point where high-performance two-stroke ATVs were popular. In defiance to the ATV trend of that time, Suzuki's first high-performance ATV was produced having four wheels, instead of only three. The Suzuki QuadRacer marked the beginning of the high-performance Quad era.

The Suzuki LT250R "QuadRacer" is the little brother to the larger LT500R "QuadRacer". Both QuadRacer models share similar design features adapted to high-performance racing conditions and they each sport the same yellow and blue color scheme, but share very few components which are not interchangeable. The easiest way to differentiate these two models from a far is by identifying each QuadRacer's blue, radiator grille. The LT250R's grille features two vanes that are oriented horizontally, while the LT500R's grille features a single vertical vane through the center.

The LT250R was offered only during the 1985 through 1992 model years. The earliest generation of LT250Rs (1985-86) can be identified by their dark-looking aluminum engines. Starting with 1987, LT250Rs were manufactured with their engines painted blue and were equipped, for the first time, with gear-driven counter balance shafts and SAEC power valve designs. The last few model years of the LT250R can be identified by their new rear suspension linkage. While earlier LT250Rs has the "push rod and see-saw"-styled Full Floater suspension, the latest ones had a compact linkage nestled in the swingarm, similar to all modern Suzuki Full Floater designs.

Standard features for the 1988 LT250R include:

High-performance, liquid-cooled, reed-valve, two-stroke engine
Suzuki Automatic Exhaust Control (SAEC) power valve for more power at all RPMs
Rugged manual clutch and 6-speed, close-ratio, transmission
Responsive flat-slide Mikuni carburetor
Gear-driven counterbalancer for smooth engine operation
Strong, lightweight aluminum rims
"T-type" seat for added support when cornering
Large, bright 60/55-watt halogen headlight with high and low beams
Front shocks feature progressive-rate springs with adjustable 5-way preload and 4-way rebound damping adjustment
"Full Floater" rear suspension with box-type aluminum swing arm, remote gas-charged damper, and adjustable preload, 4-way compression, and 4-way rebound adjustments
