The Cagiva C593 was a competition motorcycle developed by Cagiva for participation in the 500cc division of Grand Prix motorcycle racing throughout the 1993 Grand Prix motorcycle racing season. Its designation derives from a combination of elements: "C" representing the manufacturer (Cagiva), "5" indicating both the class and engine displacement (500cc), and "93" denoting the year of competition (1993). This model succeeded the C592 from the 1992 Grand Prix motorcycle racing season and was later succeeded by Cagiva’s final iteration, the C594.
Description
This model featured notable attributes such as titanium expansion chambers with reduced wall thickness and carbon fiber silencers, contributing to weight savings. Continuing the use of the "Big Bang" firing order introduced with its predecessor, this bike delivered increased peak power compared to the prior year's version. However, it exhibited a slightly less linear power delivery due to irregularities during throttle opening caused by electronically managed CTS valves, necessitating operation at elevated engine speeds.
Cagiva experimented with two distinct configurations concerning air intakes and swingarm design. The first setup, employed by John Kocinski, incorporated a centrally positioned front fairing intake coupled with a carbon fiber swingarm. The alternative layout, utilized by riders Doug Chandler and Mat Mladin, featured side-mounted air intakes reminiscent of the C592 and retained an aluminum swingarm reinforced with an upper truss structure from the earlier model.
Season progress
Throughout the season, Cagiva’s riders maintained a competitive presence despite facing formidable opposition from manufacturers such as Yamaha Motor Company, Honda, and Suzuki MotoGP. Doug Chandler consistently scored points and achieved a podium finish with third place, notably challenging Wayne Rainey’s Yamaha for second position at the opening round in 1993 Australian motorcycle Grand Prix.
The pinnacle moment arrived when John Kocinski joined the squad late in the campaign after his departure from Suzuki’s 250cc factory team. Kocinski secured Cagiva’s sole victory of the year at the 1993 United States motorcycle Grand Prix, capitalizing on incidents that eliminated competitors on ostensibly superior machinery. Additionally, riders Mat Mladin, substitute Juan Garriga, and wildcard entrant Carl Fogarty contributed valuable points. The team concluded the season with a total of 199 points and attained two podium finishes, including one race win.
