What is thr best sprocket size for gen2 haybusa from the performance side

[Dark Sky]

I have a 2013 hayabusa and i want to change the sprocket for more performance and more torque what is the best size? and do i have to change the front and back sprocket or only the back sprocket? please note that i dont want the bike to do wheelie just i need more acceleration

I need your help and what could happen if I change the sprocket?

How much do you weigh ~ and is your Hayabusa stock ?

 

[Dark Sky]

Yes my haybusa stock and my weight is around
230lb

 

[Dark Sky]

Just voodoo slip-on and BMC rising air filter

 

[RedBull]

Yes my Hayabusa is stock
and my weight is around
230 pounds suited up .

If your chain & sprockets are still in good shape ~ try a 17 tooth front or just loose 40 pounds *

-1 front, and/or +3 rear
Either or both fit the stock length chain.
stock is 18/43
Keep in mind that shorter gearing does make the bike a little quicker, but it also makes wheelies even easier.
An ecu flash will give more lower rpm timing, and noticeably wake the bike up under 6k rpm.

I would go +2 On the back. +3 or -1 was too muck for my stock busa even lowered.

He did mention that he does not want to wheelie . . .

Which is why I recommend -1 up front *

Little more wheelbase .

I'm at 18/47 at the moment,but that's with a 200/55 rear tire(which eats about 1.5 teeth of gear)and my lard ass 258 lbs.Have a brand new Vortex 45T waiting to go on when I switch back to a 190/50 rear tire.I'm good with an extra 2 teeth on the rear,gives you a little extra punch and only raises your highway cruising rpms by maybe 300 or so.

Isn't there a Gen 2 gearing calculator out there somewhere?

The -1 gear is more like 3.3 on the rear though. I had more wheelie issues with that than +2. Splitting hairs here.

Full exhaust and a Dyno tune is your fix

I geared my stock motor Gen 2 for track performance. 18-44 (+1 rear) will cover the 150mph range at the top of 4th gear.

i put a 46 tooth on the rear of mine and love it. i think its a perfect balance between acceleration and top speed for me.

I went up 3 teeth on my gen2 on the rear combined with an r1 throttle tube and rode like that for 6 years or so. I started doing more highway and the higher RPMs at 80MPH were getting annoying, so I went back to the stock 43tooth, stock throttle tube and eventually went 1 up on the front also. The +3 rear was super fun and I loved it, but the current setup feels better on the highway. I’ll probably switch back and forth every couple of years to keep from getting bored with the same.

I am curious as to why nobody runs 18\40.

Got a stock 17 on the front of my Gen 1 ~ with a 38 on the rear wheel for cruising *

I always drop one tooth on the front on stock bikes, Not much affect on chain adjustment and makes a big difference. And I am similar weight
