Following Daijiro Kato's tragic death from his injuries at the 2003 MotoGP season opener at Suzuka, Fausto Gresini, Telefonica and HRC announced on the Thursday before the Spanish GP (round three) that they would continue as a two-rider team and had signed a relative unknown, 20-year-old Japanese Supersport champion Ryuichi Kiyonari, to replace the #74.
With Kato's full factory 2003 spec RCV being given to Sete Gibernau, Kiyonari rode the Spaniard's 2002 'customer' machine from round four, the French Grand Prix at Le Mans, onwards and - although appearing slightly overwhelmed at times - took a best finish of 11th from his 13 race starts.
Realising that MotoGP may have been too much too soon, HRC then placed Kiyonari with its official British Superbike team for 2004, where he soon began to look much more comfortable - and fast.
Kiyonari clinched the BSB crown in both 2006 and 2007 before being promoted to Honda's factory backed Hannspree Ten Kate team in the World Superbike championship, where he will ride alongside former MotoGP star Carlos Checa and reigning WSS champion Kenan Sofuoglu.
