Note
The self-learning procedure of the final drive ratio is used when changing the final drive ratio according
to the ranges in the table below.
Attention
Changing the final drive ratio is only allowed for circuit (racetrack) use of the motorcycle, not on public
roads.
Attention
Changing the final drive ratio immediately makes the warranty null and void and the motorcycle can
not be used on public roads as it no longer corresponds to the type-approved version.
