42 tooth rear is awesome
Got about 750 miles on the new chain and sprockets, couldn't be happier with this very-little-additional-cost upgrade. It should be the OEM setup, puts the bike right in the sweet rpms at the bottom and top ends, significantly more grunt down low and much less need to downshift passing at highway speeds, and a quick check at the top was gratifying - still accelerating when I backed off at 145mph (indicated). Also no loss in gas mileage detected though I know lots of factors here, but seems even easier to average 40+mpg per tank without scrimping on grins.
This set is from sprocketcenter, $409.95 to my door, and $130 to my tech for the install.
