2012 Bimota HB4

2012 Bimota HB4 sits apart from the marque's usual Ducati-based and Japanese-engine specials as a Honda-powered prototype, built to explore what a 600cc supersport platform looks like through Bimota's chassis philosophy rather than a production catalog entry. This is a hand-built exercise in frame and suspension geometry wrapped around a proven inline-four, the kind of bike that exists to test ideas about handling precision more than to sell in volume. In practice, that means a machine built for tight, technical roads or track days where chassis feedback matters more than outright horsepower, and where the riding experience rewards someone who already understands what a well-sorted mid-displacement sportbike should feel like beneath them. The 2012 model carried over without significant mechanical changes from the prior year, and since production status remains unclear, documentation and provenance matter as much as condition. Buyers here are typically Bimota collectors already familiar with the brand's small-batch, boutique approach, not first-time sportbike owners. Given the prototype nature and moderate collector interest, this is a bike for someone building a focused collection around Bimota's engineering experiments rather than chasing everyday usability.
