Gearing 2008 R6

[Daytona624]

Hello all, I have a 2008 R6, basically stock, it has a custom pipe and a PC. I am racing and doing the track day in two weeks. I was wondering if some would be able to tell me the type of gearing I would need. I have it set up right now for the SMRI track. Thank you for any input.

Same bike, I'm at -2f +1r, heard others go +2 or 3 rear. Gives ya a starting point.

Is this Eric? I was gonna ask Ben and Mickey, (thunderdawg), to answer that question far ya. They both have similar bikes.

[Daytona624]

Thank you. Yes this is Eric

[Roger@Arroyo]

Ben's needs another tooth or two on the rear from when I rode it, so I'd say -2 front +2 rear

[fwrider94]

Roger, I agree. I'm -2 front and +2 rear on mine.

[Thunderdawg]

I am running -2 +4

[sweetr6]

Yeah, you should probably listen to Mickey, he pulls me down the straights every time, or maybe that's just motor, hmmmmmmm........

[Thunderdawg]

Combo of the two

[Roger@Arroyo]

Or the fact that you're 60lbs heavier than Mickey

[blendedfamily]

And gay.

[Roger@Arroyo]

True, I forgot about that part. Who's kid does Rene have then? Ortiz?

[Daytona624]

Thank you everyone. tomorrow I will pull out the sprockets I have and see if any are close to that

[Thunderdawg]

60lbs? But as bobblehead goes, isn't that unsprung weight?

[blendedfamily]

Maybe MO. the kid is pretty brown....

[Daytona624]

So I have two rear sprockets a 46 and a 48. Two front a 14 and a 15. I think stock is 45/16. what would be the best ratio ? -2 +2 would be 14 47 rear.

[Roger@Arroyo]

Go with the 48 and see how it goes would be my opinion.

What about the gsxr 1000?

[blendedfamily]

For you, 56 tooth.

What about the gsxr 1000?

Roger runs really short gears. I go for 15/46 and have been pretty-much good at every track. Shorter than that, the wheelbase is too short and I fight the bike.
