Sprockets

....using a quick change carrier (which looks cool & protects your single swing arm).

Please explain...

Standard gearing is way to high, and in the city you will be after a new clutch very quickly, I dont understand how you are either too high or too low when you enter a corner, that usually is race track talk. On corners try going in a bit quicker or slower, quicker sounds good though doesnt it.

14/41 would be about perfect for highway use, and yes replace both sprockets and chain at the same time, it actually works out cheaper in the long run

Ive only had my S4R for close to 2 weeks now. Ive been trying to go for a few ries around down but have been helf up horrifically in trafic in a few occasions (last night included). Im not sure if my clutch is going or im just get paranoid (not only does the constant in out of the clutch lever kill my hand) im noticing i have to rev it to about 2.5-3k at lights and slip the clutch when ive been stuck in terrible traffic for more then 30min or so.

I m guessing as its an italian, this is normal??

Melvin, I still run standard gearing on my S2R800 (whatever that is ). I rarely ride in town ... and have been known to do the odd trip on the old road . I don't mind the ratios ... but I don't know any different as it is all I have run.

Past talk on the forum has had me contemplating a change next time (maybe up one or two on the rear) ... but from your comments I don't really see the need.

Of course we are all different and ride differently ... so who bloody knows.

Please explain...

I'd say he is talking about a rear sprocket/carrier which prevents the cush drives from backing out and messing up the eccentric hub.

That's exactly opposite to me, Betty. I spend 95% of my time in the city with the occasional short rides "to let my hair down" 
And in the city shorter ratio is great as it gives bike a bit of a zip as well as when riding say 60k/hr 3rd feels ok while with the original set-up 2nd was a bit too high an 3rd a bit too low. Same goes for 80k/hr zones. But ...... that's exactly the same thing which is annoying out of the city with 3rd and 4th gears in the corners

Finding a miracle solution is not going to happen but considering other riders views and opinions is always interesting and educational

Hi Melvin
I used to run a 14T front on my 695 and loved it for city riding
mostly because it reduced the lugging in first gear , from what I read this increased the revs by some 600 ish rpm if my memory is correct.
The only reason I went back to 15T is when I installed a ride height adjuster to get the rear up the chain was too close to the DSS .
I was due for a new chain so did the complete drive chain but put on a 46T
on the rear , this now feels just like what I removed .
I may have lost 5-10ks from my top end unfortunately we don't get to ride at 200 ks that often on the street  so I dont care,  and 5Th and 6 feel a bit close
but down low its very nice no lugging and likes to pop the front wheel a bit more
in 1st .

MonsterDorf ... is the quick change carrier an indulgence rather than a necessity when i don't intend to change a rear sprocket for city/track/highway?

I've heard that the main advantage for _most_ people of the quick change carriers is that it allows you to run a much wider range of aftermarket rear sprockets, instead of having to buy OEM Ducati ones. If you're planning on riding the bike far enough, I think it's only 2 or 3 sprocket changes before the carrier pays for itself.

(Check the numbers though, I don't pay enough attention to SSA bike details, just sorta half remember them in passing...)

This can happen??    How does an AFAM type carrier prevent such.. um..... unpleasantness?

[goldFiSh]

Mine was 15/42 which I changed to 14/42. I've just changed to 15/44. Seems each model has different stock ratios.

the afam carrier has little "shelves" for a better word that stop the outer steel ring of the cush drive backing out against your chain adjuster and swingarm.
it can and does happen, _usually_ on the 4 valvers which tend to be ridden a bit harder but the 2 valve bikes are more than capable of tearing the cush drives as well. very, very expensive fix which can be easily avoided with the QC carrier. It does work out a little more expensive up front but i've just changed my 42T alloy afam sprocket after 25,000 klms and the replacement was $75, at a bike shop here in oz, literally a 5 min job instead of over an hour.

Damn you for giving a sensible response - so unusual. You having a snag (sensitive new age guy) kind of a day? But I have to agree, we should all be encouraging sensible responsible riding. That therefore leads me to suggest that maybe we should organise a blat at Morgan Park. I have a friend with a Cagiva Elefant and one with a ST3 who may also be keen.

Have you seen the post on Brisbane Riders about inline 4 vs V configuration?

yes to all of the above. Bevan from EuroTwins thought the risk on my 800 was low but I couldn't get the range of sprockets I wanted without the Quick change so an easy decision for me. The current ration is between the 14 & 15 tooth and is the Goldie Locks solution for me.

[melvin]

thanks for the tip, MonsterDorf 
shipping to Oz is very reasonable US$48 but since i'm going to US next month than the local shipping was even more reasonable US$8 (!)

Melvin, a link to that page?
