16 front 45 rear sprockets

[pekingduck]

Own a 2017 EX
Want to try a 16/42 set up which should give me close to 12% ~ 15% ratio change.
Plus I want to keep the original 530 chain.
Note: I barely use the 6th gear during my rides (now 13,000 Kms).

Just ordered a 42 Tooth rear sprocket (JTR #302.42).
Anyone has the front sprocket number for a 16T or 17T? (2017 EX)
Much obliged.

2002-2013 VFR800 uses a 16-tooth that will fit - P/N 23801-MCW-D00.
All CBR1000XX Blackbirds use a 17-tooth that will fit - P/N 23801-MAT-760.
Factory sprockets have rubber dampeners on the sides for quietening.
.
Or you can order a JT sprocket, JTF339RB-16 or JTB339RB-17 with rubber dampeners, JTF339-16 and JTF339-17 without the dampeners.

Good luck!
