Gearing

So what you running now? Can I ask what your getting out of each gear and what you got before?
Think i`m running a 17/42 at the mo, and was going to change to a 16/42 as suggested by that byranthegoat bloke

I currently get about 50 in 1st and 70 in 2nd. Which seems unbelievably short as is compared to 90 in 1st and 115 in 2nd on the R1!

Steve the 16 front is a must, the rear you can play about with but to give you an idea on track if youve watched the bsb this year at knockhill its a wee twisty track wi only two straights where your up through the gears so the 2 up at the rear helps your losing about 15 mph off the top ,the first gears are quite short on the apes,Dalmation glad to help go gixer hunting duff them power rangers up...

pre 04 models -1 front and +2 up back seems the best combo for me, keep the std length chain and its a nice short wheelbase
ck

+2 on the back giving you....?
Theres a 42 on the back at the mo.
Oh and yeah I`m not fussed about max top speed. These probably top out at about 155-160 max anyway dont they?
I just dont want to spend too much time faffing through the box between bends.
Thats why I was wondering what the 16/42 gearing equates to in each gear. Anyone know???

Like with the R1 at Brands indy, I could do most of the track in second as it topped out at about 115 which saved alot of up and downshifting.
Cheers byran/ CK :thumbup

been running 15/44 for a while and its huge fun accelerating everywhere like a nutter, made riding around town an awful lot easier to, but one thing to be aware of.. for slogging along at 60 or 70 on the big fast boring roads you will be sitting at much higher revs than you would on stock gearing, meaning you burn more petrol... not to mention losing top speed (probably only matters on track, not like you can ride that fast on the road anywhere safely)

about to change to 15/42 since my chain is at the end of its life and petrol prices are stupid.. i remember when it was 80p/l ... lol

almost forgot, found the link searching around on the forum before settling on 15/42:

really neat little site that works out all sorts of stuff, half of which was beyond my patience (contact of teeth per revolution to calculate chain wear?? really...)

Haha, classic actually LOL`d
Will check that out cheers :thumbup

Right according to that even if I`m running a 17 in the front (stock), I should be getting
60mph in 1st and 86mph in 2nd!
When I`m getting 50 in 1st and 70 in 2nd!
So somethings not right.
According to this I have 14/42 gearing to get those numbers....
That sprocket cover is coming off tomorrow to confirm whats under there!

Some people have changed the gearing to that extreme(****** weirdo's) to save fuel and to take it easy(buy a bloody scooter),Had a look at that site maybe im thick but couldnt make head nor tail of it......doh

But that would make it worse of fuel because its so high reving!

Hope that aint what I`m running though, as was hoping to liven things up abit with going down a tooth on the front! Its not quite got the wheelie power acceleration of the R1. There is no way it would come up in second with just the power. It will come up in 1st fine, but the gear is so short its through before you hit the balance point. Maybe it needs some other attention :/ Thinking of getting that griff fella to do an assessment. Just got no spare cash at the mo! arrgh

yeah 16/44 is the best and good for 168 mph top end and MUCH better acceleration, puts max torque at 7.5k
ck

I`ll let you know whats under there if I get round to whipping off the sprocket cover tonight

i expect it wil be a 17 matey
ck

I hope so. But then why am i getting 50 in 1st and 70 in second?? :dunno

I`ll let ya know

bizarro mate

16/43 work for me nice all round.:thumbup

yeah the low top speed in 1st is a strange one, especially since that site reckoned i would only get about 45 in 1st and i can easily see 60 as im changing

you are measuring it by accelerating full whack and glancing at the speedo just as you go to change up right? cus it only reads that high if you accelerate madly, probably wouldnt sit at 50mph for long in 1st even at redline...

SteveR when was the last time you checked the clutch plates? i had horrific clutch slip for a while and it really made the power dissapear.. you can scuff up the steels if they arent too bad but that only lasted a week for me, went with a barnett performance clutch and it drives a beaut.. just a bit harsh on the left hand lol

you def wanna get to the bottom of the lack of speed/power, unless you are on the stock 17/40 gearing power wheelies should come quite easily and naturally if you encourage them,

Yours is the newer shape though aint it wolf? 04 onwards? Id expect that to have slightly taller gearing as it has the power to use it.

i`m getting 50 by slowly reving out the gear to the limiter.
I`m mean internally all 02 ratios should be the same, so if it has been geared up a tooth on the front that mean with the 16 it`l have even shorter gears! lol

Like I said all will be revealed when I get that front sprocket cover off!! (WHEN)
I`m hoping it is a 17, probably being a tooth up on the front would explain the lack of second gear power wheelies!! Any bike that sounds like this should power up in second

CK- tell me about it!

Ken - cheers I`ll clarify whats on the front and maybe dabble with the back over winter

yeah thats a fair point, the newer models have a different ratio INSIDE the gear box aswell but even so i would be surprised if it is THAT vast a difference

from the sounds of it you are not accelerating properly (as in.. full throttle ) when you are trying to measure its top speed in 1st

mine would probably top out at 45-50mph if i just slowly increased the revs til it was at about redline.. but if you accelerate fast from a stop by the time its at that peak and im shifting to 2nd its easily closing in on 60, infact im sure i saw a 70 when i had stock gearing

if you havent already find a nice quiet place (closed roads n all that legal stuff.. ) and have a test of its full acceleration power, just be careful of wheelies & wheelspins as you pull off

i guess the bottom line is gonne be this: people measure their "top speed in 1st" in different ways, so there is always gonna be odd numbers quoted

p.s another example, measuring top speed of the bike in the same different ways would produce different results also:
1, accelerate like a lunatic through most of the gears until you are in top gear and about the maximum you want to push the engine to: this will give you around 160mph depending on gearing etc etc
2, accelerate to a fair speed and then when you are in top gear suddenly decide you want to test it and crack the throttle open: revs will slowly rise and speeds will rise slowly also.. probably give you a 'top speed' of 20mph less than above method by redline..

i guess its all about the science of riding, forward momentum and all that good stuff

I would say your example probably comes down to the fact that by the time you`ve rolled on in top, you run out of road before hit max rpm. And also like you say less run up to push through the massive areodynamic drag at that speed I guess. Where as first the power is so that maxing it out is a sure thing. Everything is mechanically set so theoretically I shouldnt make much difference if you`v pinned it to the redline in first or wound it on. IE the gear ratios internally and externally should always equate to the same speed at a given rpm....

At least thats what I reckon! lol
I know where your coming from though. Its probably down to the limiter taking awhile to slow momentum when you`v banged into it perhaps if you get abit more on the clock that way?

Oh dont worry my friend, i`v tested it properly I`m not the sort to ***** foot around with these things. I`m in no way scared to open it up, been wheeling it around from day 1 lol. Thats what made me notice the short gears!
I used to see 175 plus on the R1 back in the day, everytime we went out (saw 186 on the clock once) riding on the closed private roads By comparison the Mille is abit slow accelerating hard through the gears, which is why I`m definitely gonna down gear it what ever I find under there. Just hoping it doesnt make the gears too much shorter! lol
