Yamaha YZF250 Ignition Unit (2001 ONWARDS) - Modification: Ref 030416P1
 

Advantages are a peak power increase, the ability to over rev the machine and hold the gear longer before up-shifting, which particularly benefits short circuit courses.


However, this modification does lose a small amount of power at low to midrange.
