Two icons of Japan’s performance motorcycling era are crossing the virtual auction block as part of the Frank Sega Collection — a 1975 Kawasaki H2 Mach IV and a 1979 Honda CBX 1050. Both will be offered through Premier Assets LLC via Proxibid on November 5, with bidding starting at 11:05 a.m.
The 1975 Kawasaki H2 represents one of the most notorious motorcycles ever built. Known as the “Widowmaker,” its 750cc two-stroke triple delivered unmatched acceleration in its day. This example, a model H2-750 Mach IV, carries a matching motor number H2E43673 and VIN H2F43392. The title shows 4,950 miles, though the odometer and speedometer are missing. The bike’s engine cranks, but it currently has no key. It’s located in Chardon, Ohio, and features a chain drive and the classic H2 layout that made it a legend among thrill-seekers.
Joining it is the 1979 Honda CBX 1050 Super Sport, one of the most ambitious production motorcycles of its time. Powered by a 1,047cc inline-six, this CBX combines racing-derived technology with road manners that helped redefine superbike performance. Showing 10,183 miles, it features double overhead cams with 24 valves, a 5-speed transmission, and telescopic front fork with dual rear shocks. The CBX’s engine cranks, and unlike the Kawasaki, it includes a key. Also located in Chardon, it carries VIN CB12014778 and remains a landmark in Honda’s engineering legacy.
Would you pick the raw, two-stroke fury of the Kawasaki or the refined six-cylinder power of the Honda?
