This is a very high quality, close-ratio gearbox to fit the TR/GT 750
Beautifully machined and of far better quality than a standard GT box.
Very limited production run - when these are gone it will be a minimum of 16 weeks lead time for a fresh gearbox.

The ratios are much more progressive and tighter than on Nova close ratio conversions which for the sake of economy only change the first and top ratios - see chart in pictures.
