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.

Full five speed close ratio gear set with three undercut engagement dogs for fast positive gear changes. Supplied assembled and ready to fit using existing selector mechanism.

The ratio's have been chosen with a view to the type of racing for which these machines are being used and are therefore not the same as used in the period Honda racers, which were intended for use at the very highest level, ridden by professional riders against similarly prepared machines from other manufacturers.

Our ratio's are as follows:

1st 2.055 : 1
                      )      27% 
2nd     1.5 : 1
                      )      17.3%
3rd   1.24 : 1
                      )      14%  
4th 1.065 : 1
                      )      9%  
5th 0.969 : 1
 
Overall 1st -5th  52.8%
