Description
1974 Kawasaki G3SS-D 90 – 1,892 Original Miles – Original Paint Survivor – Fully Serviced – Rotary Valve Two-Stroke
A true time capsule from Kawasaki's golden era of two-strokes.
Offered here is an exceptionally original 1974 Kawasaki G3SS-D 90, built in December of 1973, showing just 1,892 original miles. Finding one of these lightweight Kawasaki two-strokes in this condition is becoming extraordinarily difficult. Most G3SS models were purchased by young riders and ridden hard until they disappeared. This example escaped that fate, spending its life in a collector's ownership and being stored indoors, preserving its originality for more than five decades.
This is an original paint survivor that retains the vast majority of its factory components, making it an outstanding candidate for any serious Kawasaki collection.
Legendary Rotary Valve Performance
The G3SS may be Kawasaki's smallest full-size street motorcycle of the era, but don't let its displacement fool you. Equipped with Kawasaki's legendary rotary valve induction system and a Mikuni carburetor, this 90cc two-stroke delivers performance that far exceeds what most riders expect.
The rotary valve induction gives the engine exceptional throttle response and surprisingly strong acceleration, allowing this little Kawasaki to punch well above its weight class. It offers far more excitement than virtually any 90cc four-stroke of its day while maintaining excellent fuel economy and remarkable reliability.
Sharing styling cues with Kawasaki's larger performance machines—including the S1 250/350, H1 500, and H2 750—the G3SS provided riders an affordable entry into the Kawasaki two-stroke family.

Original Paint Survivor
One of this motorcycle's greatest strengths is its originality.
The tank retains its factory original paint, which naturally shows honest signs of age after more than five decades.
Imperfections include:
-
Small ding on each side of the fuel tank
-
Minor touched-up area
-
Interior of the tank was previously sealed by a former owner and is cosmetically bumpy & unattractive but functions properly with no leaks
These imperfections are documented honestly and simply reflect the motorcycle's originality.
Our service department invested:
-
26 hours of professional shop labor
-
15 hours of cosmetic detailing
-
$508 in new parts
Total restoration and preservation investment exceeded $4,400, not including the purchase price or transportation to our museum.
Every motorcycle we sell receives the same careful attention because we stand behind what we offer.
