hello, have you found a 16t front sprocket in europe by now? looking for one too!I
Are you using a Driven Racing?
I am yet to find one available in europe, from driven, or any other supplier for that matter.
no it's not nescessary to ride that low in revs but it makes it smoother over the whole range.Lookin at the DYNOs I wouldnt get my hopes up for anything more than marginal performance losses at <4000 rpm
My question: is it necessary to rev that low?
mine's got about 6600km right now.
but i am convinced that all stock bikes run lean because of emissions and therefor could use a litlle more fuel.
first valve check is around 15000km you say? sweet, got another year to go then![]()
Where did you get it from??? The cost to get one from the US is crazy for europe....so ,i got my 16t sprocket.
i REALLY like it.
it sort of changes the bike from constant 'RACE' mode to everyday driver mode.
longer pulls between gear shifts.
and 6th is a REAL overdrive,meaning, no 6th gear below 80km/h (= 4000rpm)
but i plan on richening up the fuel to have a smoother engine below 4000rpm aswell.
so 16/45 is a good thing for me, altough 15/43 would have been (maybe) even better choice (stock, without a richer mixture).
How can this be? I have never heard of taller gearing improving acceleration before. Defies logic. If a 16 tooth improves acceleration, why stop there?I have heard that the 16t makes the bike faster 0-60mph, and from everyone who has it a very positive reviews.
I’m not saying one person is right and one is wrong here but I have changed gearing on my last two bikes.How can this be? I have never heard of taller gearing improving acceleration before. Defies logic. If a 16 tooth improves acceleration, why stop there?
I can see how switching to a taller gear (16 tooth)would make for lower rpm more relaxed highway cruising.
I can see that switching to a shorter (14 tooth ) would make for snappier off the line response and closer overall gear ratios.
You can have a choice, but you cannot have your cake and eat it too.
If I was big guy riding mostly in a low speed environment it might pay to shorten the gearing.
A light weight person doing a lot of highway might benefit from taller gearing.
As a slightly lighter than average weight rider who does mixed riding, the factory gearing works ideally for me, and that makes sense as I am sure they were aiming at Joe/Jane average. JMO.
I’m not saying one person is right and one is wrong here but I have changed gearing on my last two bikes.
On the first one I went down one tooth in the front. Didn’t notice much difference when it came to acceleration but easier to ride at low speeds in the city. Max speed didn’t change.
On the next bike I did the opposite, I went down 3 teeth in the rear. Did notice lower revs at higher speeds but no difference in acceleration.
Both bikes performed better for their intended use. On the second bike I was riding at speeds between two gears on twisty roads before I changed the gearing. The best benefit after the swap was that I now had a natural gear for the twisty roads.
The 401 is very shortly geared. At 35km/h I’m already in 3rd gear. My guess is that up one tooth in the front won’t make the bike feel slow at all but will result in lower revs at 100km/h.
I have only used the bike for commuting so far so I have no idea what gear I’ll end up riding in on twisty roads.
