Hi ,
What sprocket size front and rear are best for the vf1000r?
Is anyone running different size to standard, and are there any performance gains
Cheers Mick
Parts diagram shows 17/44 for RE.
I dropped revs by 600 in top on my CBX by swapping sprockets. Acceleration down (but good enough for me).Upside is great fuel consumption and less engine wear cruising along.
U.K. spec is 17/43 but it will pull an 18t front no problem,a few of the guys including myself use an 18 on the FE,drops rpm by 500 in top.
My R runs 17/41 due to using 520 pitch chain and an 18 not being available
Ok cheers 
, I may try an 18T front then as bike feels like it needs another gear when in top gear…
I have 16/45 on my VF1000R and it eats up the gears and makes it a LOT of fun on all roads bar motorways - tops out at 130mph now but pulls like a train to it. It also makes 5th pretty much usable from 40mph, the torque from these motors is great.
If im being honest ill probably try a 17t front with the 45 rear sprocket, but a 6th gear would certainly help! Im just not prepared to spread the gearing to make 5th an ‘overdrive’ / cruising gear as its extremely usable and fun right now.
Theres always a compromise!
