Changing the gearing? - xlewisbdx - 07-10-12
Can I ask what your thoughts are on changing the gearing, I am thinking of going down to 14t on the front and up to 52 rear.
What are your opinions on that and how far will the bike come up if I accelerated hard?
Re: Changing the gearing? - xlewisbdx - 07-10-12
Also on a quick note, would my speedo still read the correct MPH if I change the gearing?
Re: Changing the gearing? - darrsi - 07-10-12
The speedo sensor spins inside the front wheel, and your speed is determined by rotations of the wheel, it's nothing to do with gearing!
As for the gearing, those nice people at Yamaha have spent a lot of time and trouble getting things right so unless you are using it as a stunt bike then personally i wouldn't bother touching it!
Re: Changing the gearing? - trudd - 08-10-12
As Darrsi has said the speedo runs from the front wheel on the FZS so no worries with that. Some (newer I believe) bikes run the speedo from the front sprocket so that would mess up the readings if you changed the sprockets.
In my opinion, the gearing is fine on the FZS as standard unless you intend to use it for something other than "normal" use. I'm lowering the gearing on mine to hopefully help with my Motogymkhana. It isn't really needed but I think it will help me with low speed manoeuvring as the engine revs will be higher and the on/off throttle snatch won't be such as issue - but I might be completely wrong.

I am just using it for cheeky wheelies every now and then :lol
Re: Changing the gearing? - Tiberius Onklevaart - 08-10-12

Remember, these bikes are ALL made to a compromise, for joe average, for many reasons as well as emissions regs and performance. There is no good reason to tailor a bike to suit YOUR requirements, if average is okay then avarage is good for you. I have changed my gearing to make it rev less at motorway speeds and above as the standard gearing feels as if you are in 5th or 4th all the time. 8k at 100mph now. Reaps 60mpg ridden hardish. Acceleration is still very good. I have also gone up 10mm on the front tyre to give a bigger footprint and NOT ot run off the edge of the tyre at the front. I also went to the 2002 type fairing as the lights were better. Did My Mitsui spend all that time making awful headlamps on the Mk1 that were fit for use? COmpromised suspension very budget, and so on. Many things can be improved on but on the other side there are many ways to screw it up. If you don't know what you are doing, LEAVE IT ALONE.

Does anyone know what my top speed would be reduced to if I went 14-50/14-52?
Re: Changing the gearing? - trudd - 15-10-12
I now have a shiny set of 14/50 sprockets to fit so I'll let you know the differences better this and stock soon.
Have you seen a 52? I think you might have to get this as a special.
Re: Changing the gearing? - xlewisbdx - 15-10-12
I have seen a renthal 52 on eBay.
Can't seem to find it, I was looking this morning I'm sure I found one.
Re: Changing the gearing? - xlewisbdx - 16-10-12
Any news on the 14-50? what do they feel like?
Re: Changing the gearing? - Tiberius Onklevaart - 16-10-12
I pointed out on your other gearing thread what 14/50's are like matey
Re: Changing the gearing? - trudd - 16-10-12
I haven't had a chance to change them yet. Hopefully be able to get it sorted soon.
Re: Changing the gearing? - trudd - 14-01-13
It's been a long time coming but I finally got round to fitting the sprockets and have done a couple of hundred miles on them now. For around town and commuting on dual carriageways its great. They have taken the revs in top gear at 60mph to 5700rpm from 5000 so it does make the bike a bit more buzzy but has given it a bit more punch without having to rev it too hard.
For my commute and low speed work it has definitely made it nicer for me.

Thought you learned your lesson after the bike crash? :rolleyes
Re: Changing the gearing? - Lumpy - 14-01-13
bloody thing is revvy enough without lowering the gearing
. I found the standard set up to be wheelie happy just on the throttles. With my higher gearing it take a bit more effort to get it up but the video I saw of my wheelie 2 septembers ago shows that 400 yard 3 gear wheelies at balance point are nicely doable. Shame the Police weren't quite so impressed.

Excuse me mister! I am restricted and can't do them. When I wanted to do them it was before the crash
Re: Changing the gearing? - JZS 600 - 14-01-13
I think the gearing on mines spot on, wouldn't imagine changing it

Re: Changing the gearing? - JZS 600 - 15-01-13
Yeah, I know,,,,, but:
When I'm commuting it's sitting around 6.5-7.5K, it accelerates well, not got an issue with the top speed........
What's not to like
