Honda’s 1987 homologation sport bike based on its racing V-four technology was the Honda VFR750R, commonly called the RC30.
Honda built the RC30 to satisfy production requirements for international superbike racing. It used a 748 cc liquid-cooled V-four engine with gear-driven camshafts, a single-sided swingarm and a lightweight aluminum frame. The motorcycle was produced in limited numbers compared with ordinary road models.
The RC30 became strongly associated with Honda’s racing success, especially through the factory-supported RVF750 race machines derived from the same engineering family. Its high specification and limited availability made it highly desirable among collectors.
The model is often confused with the later RC45, which was Honda’s subsequent V-four homologation superbike. The RC30 is the VFR750R designation, while RC45 refers to the later RVF750R introduced in the 1990s.
