World Championship Motorsports

World Championship Motorsports (WCM) was a Grand Prix motorcycle racing team formed in 1992 by American Bob MacLean and British Peter Clifford (MotoGP).

The frames were built by ROC, Serge Rosset's company (the motorcycles the team entered were listed as ROC-Yamaha for this reason), and Peter Goddard was the first rider that WCM signed.

In the next five seasons riders like Niall Mackenzie, Andrew Stroud, Neil Hodgson and James Haydon rode the ROC-Yamaha bikes for WCM.

[2] The team experienced its greatest success in 2000 when rider Garry McCoy won three Grand Prix races; however inconsistent results relegated him to fifth place in the final standings.

Peter Clifford would seek a customer version of Honda's potent RC211V V5 engines, and proposed that the team pair them with a Moriwaki chassis.

[5] After initially talking with Regis Laconi, Steve Hislop, Jose Luis Cardano and Jay Vincent,[6] the team eventually announced Chris Burns and Ralf Waldmann as their riders for the upcoming 2003 season.

After being forced to sit out the Japanese GP due to engine-related issues, the FIM found that the motorcycle was not in conformity with the championship technical regulations the following race and the team was disqualified.

In a 2009 interview, Peter Clifford revealed that Blata only managed to produce "a lump which represented 90% of one motorcycle, but the engine never ran even on a dyno."

At the end of 2005, WCM director Peter Clifford announced his intention to run KTM engines in 2006, with Jeremy McWilliams and Alex Hofmann being named as potential riders.

[19] Clifford presented conflicting statements on whether the team would be receiving official support from KTM, or simply using leftover engines from the failed 2005 Proton KR-KTM collaboration project.
