    Am going to -1 tooth (16 to 15) for the front sprocket - I'll post up the difference when it's fitted up, I have a +2 tooth (42 to 44) hard anodised Renthal rear waiting in the wings if I'm not happy with the front sprocket mod...
    Still running 530 pitch chain, for what I'm doing I have no desire/need to go lightweight...

    Made a big difference on my 600 . I was told that going -1 on the front has the same affect as +2 or 3 on the rear. Both together is supposed to be to much thou.

    Keep us updated fella as iv been thinking of doing it to mine

    I went for just +2 on the rear with a lightweight chain and it feels pretty much perfect. More than this i think will be hard to get the power down and stop the wheelies.. but i'm not that quick.

    It can power wheelie in 3rd now.. :)

    Nice stuff Zee, I've got used to having my weight well forward / covering the rear brake during hard acceleration and have got myself in tune with the bike now and am looking for some more urge - not bothered about high speed. I'll be fitting the front sprocket tomorrow night and will try and get a run with it during Friday afternoon. If it's not quite what I want then I will definitely also fit the 44t rear - big power wheelies sound fun to me !!!

    If I'm still unhappy I can always go 15/46 lmao

    The stunt riders performing at the bike show i attended on the weekend had rear sprockets nearly as big as the rear wheel lol

    On standard gearing and quite aggressive throttle mine lifts in 2nd-3rd, not very high though, too be honest I'm utter crap at wheelies, I'd love to do them properly

    Masher are you fitting a speedo healer? Your speedo will be a bit out. Also your chain will be alot further back in the swingarm. His would slow the steering a little bit.

    Saying that a 55 rear tyre would probably even it out a bit as they turn better and have a bigger rollin radius so could even speedo reading out a bit

    I would tend to go up on the back rather than down on the front to make wheelbase shorter.

    My thoughts match yours Fs, I've ordered a 55 section Bt015 - saying that - if I drop the 44t rear on it'll even things up some.
    I'll think about speedo healer if there's a big difference 'act vs ind'.
    Go too far up on the back and I'll need a new chain +2 links, with the -1f and potential +2r route I can get away with keeping original chain for now - thats my thinking anyway !!

    I bought a 44t renthal but haven't fitted it yet. Should make a good difference in acceleration though andthe standard chain will fit (hopefully!) but it will be quite far forward in the swing arm.

    I'm not going to bother with a speedo healer as I don't think it will be that far out and they're about £90 which is stupid for what it does.


    If you go -1 +2 you will have some serious acceleration!

    you'll be ok with the std chain, and yes the wheel will be forward in the swingarm so the steering will be a little quicker, my equation for this is as follows:
    quicker steering + hyper fatspanner acceleration = good fun aplenty

    ^ I'm going to take a sat nav out with a speed display and just remember the important numbers such as 30, 50, 70 and 96.

    should be fine.

    Zee, I don't understand the 30, 50 and 70 numbers but recognise the 96 as the key point to shift up from 1st...

    Hehe, well with your gearing mate i think 30, 50, 70 and 96 are all shift markers for you! ;)

    If you can be bothered can you weigh the standard sprockets agains the renthal. Would be interested to see what the difference is.

    Usually the rears are much lighter but doesn't feel much different at the front.

    Cheers

    Yeah, I am +2 at the back with the standard chain and all is well.
    P.S. 20+ years riding experience and I still have to concentrate hard if I want to open the throttle fully in 2nd gear on this bike :)

    Well I managed to check out the -1 at the front, before the rain hit wtf, it's ok but not as much extra drive as i hoped for sooo the +2 on the rear will be fitted during Friday...and will be duly tested if the weather is ok..
    Fs there felt to be a bit of difference between the front sprockets, but I didn't weigh them - I'll weigh the front i removed and will def weigh both rears. I'll have a look at the renthal website and see if they list a weight for the front sprocket so we get a comparison, btw I didn't go for the ultralight drilled one...

    Oh yeah the front was lifting gently under hard 2nd gear acceleration, no rear brake needed, just moved my weight forward a little and it stopped it coming up - easily manageable is the message at the mo !!

    thanks

    does your front sprocket have extra holes drilled through the centre part or is it solid?


    i was thinking of changing to a renthal front if i can get the unltra light version in the standard size. i dont want to alter the gearing on the front sprocket as i think +2r is all im after

    ive got a feeling the only renthal front in 16t 530 is solid though, not the drilled lighter version.

    the normal renthal one may be a little lighter than the OE one but i doubt there will be much in it.
