How Kawasaki Fixed The H2's 'Widowmaker' Reputation
Key Points:
- In 1972, Kawasaki released the Mach IV H2 750, a powerful and notoriously difficult two-stroke motorcycle known as "The Widowmaker" for its abrupt power surge and challenging handling.
- The H2's aggressive power delivery, combined with a light front end and flexible chassis, often caused dangerous high-speed wobbles and loss of traction, leading to its fearsome reputation.
- In 1974, Kawasaki improved the H2's safety by lengthening the wheelbase, adjusting steering geometry, and smoothing the engine's torque curve, which reduced peak horsepower but enhanced rideability.
- Despite these improvements, environmental regulations, the oil crisis, and tightening safety standards led to the decline of two-stroke motorcycles, prompting Kawasaki to shift focus to four-stroke engines by 1975.
- The H2 was succeeded by the Kawasaki Z1 900, a more refined superbike, while early H2 models remain highly prized by collectors for their raw, unfiltered performance and historical significance.
