2026-10-28 12:50:00 2026-10-28 13:00:00 America/Los_Angeles 1973 Suzuki GT380 Tempe, Arizona - A clean, bone stock example of Suzuki's surprisingly advanced and high-performance mid-sized two-stroke tourer. https://iconicmotorbikeauctions.com/auction/1973-suzuki-gt380/ Iconic Motorbike Auctions concierge@iconicmotorbikes.com

Please note: This bike doesn’t currently run therefore there’s no cold start video.

Nicknamed “Sanpachi” (Japanese for “Three-Eight), the GT380 was released by Suzuki in 1972 alongside its big sibling—the GT550. At the heart of the bike was a 380cc two-stroke triple putting down 37.4 horsepower and 27.5ft-lbs of torque—at 7,500rpm and 6,500rpm respectively. 

Tipping the scales at just over 400lbs wet, the GT380 was smooth, comfortable, and large enough to easily accommodate a passenger. Later is the model’s first year of production, its front drum brake was upgraded to a single disc setup. 

Like its larger 550 stablemate, the GT380 had a one-piece cylinder head cooled using the ram-air cooling system that the Hamamatsu marque had originally developed for its road race bikes.  It also featured a unique 3-into-4 quad-muffler setup. 

In the October 1976 issue of Cycle World, the magazine did an extensive road test of the GT380—which can be read HERE.
