The previous version Nova Ducati Single gearbox was an ongoing evolution based around the standard Ducati design.  As such its performance and durability was limited.

In 2016 we fully re-designed this gearbox with specific designs for both wide case and narrow case engines to maximize strength and performance.  Two sets of ratios were designed one the same as a standard wide case (B) and the other a close ratio (C) set for circuit racing. 

The standard ratio B set retains the use of the kickstart whereas the close ratio C set is not compatible. 

The kickstart option could be provided for the C set on request.
