Honda's V-Force

Book excerpt: During the decade prior to the advent of the World Superbike Championship in 1988, Honda's RVF four-stroke motorcycles dominated the World Endurance Championship and the World F1 Championship. Initially, however, Honda's V-4 powerplant was a total disaster. But with major financial reinvestment, the engine's fortunes turned and it went on to enjoy significant competition success. This is the story behind the development of Honda's four-stroke RVF and RS racers, as well as the VFR streetbike, which has remained a highly sought-after motorcycle for more than a decade. Author Julian Ryder follows Honda's four-stroke engine, from the early disappontments, to the competition successes of Joey Dunlop, to the introduction of the fuel-injected RC45, which is still the basis for today's Superbike races. Also included are detailed competition results and motorcycle specifications.
