    Gearing

    Hi all

    I have the Falco geared at 15F and 43R, giving approx 140kmh @ 6000rpm.
    Having fitted the Rene air box and had PC111 mapped, it feels a bit short.
    Im thinking of changing to either:

    1) 15F and 41R

    or

    2) 16F and 43R

    Any thoughts or experiences? Not after outright speed (need my license!) and ride mainly in the hills...


    cheers

    Pete

    Both will work, but a 16 front will give your chain a little longer lifespan. I'm running a 16/44 now.

    BTW: Both those setups are better for cuty traffic.

    How about 3) 15-42 ?

    I used 16/44 on the Falco.

    But if you really want to know about gearing look HERE

    Thanks Ross...
    will also be cheaper (front sproket less $$ than rear) and will affect chain length less...

    Think I will go this way... 15/42 too small a difference I think...

    16/43 is a great improvement over the stock 16/42. i worry about going to 16/44 as i feel it may reduce the all around riding capabilities. the 16/43 is very well mannered over the stock in the city and great in the twisties. the front end is definitly lighter and want to go skyward. i'm very happy with the 16/43. i am tempted to try the 16/44 but i dont think its what i'm looking for.

    15/43 would be equivelent to 16/45

    I think 15/42 is magic. The gears feel perfectly spaced like you're running a close-ratio gearbox in the twisties as seems to keep the revs in the sweet spot of the engine's powerband. 1st is not at all too low, and 6th is very usable.

    Ok,,, a little maths gives me:

    15/43 = 2.86
    16/45 = 2.81
    16/43 = 2.68
    15/41 = 2.73
    15/42 = 2.80
    16/44 = 2.75

    Hmmmm.... due to cost and ease, I think I will go 16/43. Very close to the gearing I was initially running, which was a bit of a pain in slow traffic, but bike running much stronger and crisper now. Wondering if fitting the Oz wheels will affect how the different gearing set-ups feel? Less gyroscopic effect?

    I was running 16/42 and never got into 6th. went to 16/43 and useable all through the rev range. My OZ wheels only made the turning in easier and also less unsprung weight which is a benefit for quick changes of direction, not sure if that effects the ease of spinning up the rear wheel.

    It sure will as there is less weight in the wheel.

    I have both 16/43 and 16/44. Both are good. Run currently 16/44 on the CF wheels. If I was touring I'd probably go for the 16/43, but it isn't that big of a difference.
