Well, i run 16/40 now and think it´s a bit slow...and revs like ´ell
70 front wich makes the speedo somewhat unreliable, 180/55 rear...
9000rpm in 2nd & 3rd gear is 120 & 160km/h on the speedo, guess it´s a bit higher due to the front...

Anyone with same setup that has checked this out?

Running the 16/40 gearing with std 60 profile and front and rear and 160 rear as such so can give you an idea over the next couple of days when I sneak out for a fang...

I run 16/41 which I though was going to give better acceleration, but in fact it turned out to be,( according to the calculators) only about 2kmh different at, if I remember rightly, 4000 revs

I run 16/41 and find it good, but it is street riding more than motorway. I want all my fun in the 0-120. You will have to re-calculate for the 180/55. I'm sure someone here will have a formula for that so you can compare.

Damm didn't quite get the result you wanted in secong gear ..mmmmm got 6mths and $850... Just as well I didn't pick third gear it would have been worse But yes from memory pretty sure 160k's is 9000rpm in 3rd...

yes can confirm 120kph 9000rpm 2nd gear 160kph 3rd 9000rpm with std 60 profile tyres and 15/40 gearing.... who me no officer i wasn't riding

So one can say that a 70 profile front is one tooth on the front sprocket

I wouldn't worry about that to much. I checked the speedo with GPS and it appeared to be quite accurate! I have a 70 front too.

Somehow that sounds a little bit too short!

my mistake lookin over my shoulder incase I was followed.. I mean 16 tooth front

ok I admit my typing skills arn't the best so you won't find me in high heels and a skirt sitting behind a desk or auditioning for the next production of rocky horror for that matter
