Supermono

April 2008

 

We are continuing to develop a range of transmission parts for the 4 stroke motorcross engines being converted for use in supermono racing.  Close ratio road race style 5 speed gear clusters have been produced for the CRF450 and YZF450 engines.  Higher ratio primary gears for the CRF engine are now available. 

A 6 speed gearbox for the CRF450 has successfully completed its first meeting, being placed 6th and 4th in the British Supermono Championship rounds at the Snetterton race track on 11th and 12th April. 

A direct replacement for the standard gears.  All gears incorporate 3 undercut engagement dogs for rapid changes and positive retention when engaged. The transmission set is assembled using the standard input and output shafts, bearings, bushes, thrust washers etc.

We have versions for the 1999 -2005 model, and the 2006-and onwards model
