The 06-1059/06-1464 kickstart lever assembly was fitted to 750s
and 850 Mk1 and Mk2.
850 Mk1
A and Mk2
A had the same pattern kickstart lever as the Mk3 ('A' models having the black cap/bean can silencers) but
without the Mk3 lever's spring-loaded pedal ball detent so the 'A' (06-4249) and Mk3 (12-1018) assemblies have different part numbers.
Edit:
The Mk3 12-1018 assembly supersedes 06-4249 and can be fitted to non-'A' models.
