largest front sprocket that will fir 2001 fazer 600

[jackinacabin]

The title says it ... I want to put the  maximum I can to make this very rapid bike a bit less of a screamer and less gear changing , I have a Kliktronic gear shifter as I am disabled  but even so minimising changes is good ...   I have a 17 waiting ti be fitted here but wonder if i can go higher without getting a longer chaib ... cheers  folks

Not sure to the answer of your question, but this may interest you anyway.

Thanks for the link ... I hope my 17t will fit despite the warning there that the chain needs extending - the chain is about half worn ... if not I will get a 16t and leave it at that until the current chain is needing changed .. I imagine when the chain  needs replaced I can simply count links and add another couple and order a chain that long with the apropriate sprockets ...  Looking at a video of the space around the sprocket I think an 18 would be too close to the clutch rod ...

Thanks for the power commander link as well

You are limited by the space between the chain and the clutch pushrod,  I know a 16 tooth fits, but would have doubts as to a 17tooth one fitting safely as it would be extremley close to the pushrod with the chain on. The bigest available rear is 49, but you could probably have a 51 tooth made.16/51 would be almost the same as 17/48 ratio wise. Smallest available rear from JT spockets (I use these mostly) is 38 but it would probably be too small and raise the gearing to much. A 16/45 would be almost the same as 17/48 ratio wise but JT sprockets do not do 45 only 44 or 46. A16/44 would be as low as I would go. Any smaller would be like trying to take off in 2nd gear and would not do the clutch any good. I would not be inclined to recommend the 17 as it could interfere with the clutch operation and that is something you do not want.

Klilktronic is a nice bit of kit, good to see you are still able to ride

Hi , Unfazed , yeah it looks close alright ---  I will have a look and make very sure it misses if i use the 17t. I may be muddlesd  but I think I would need to go  down in teeth on the rear sprocket to increase the gear ratio? The Kliktronic is ace , makes a huge difference , I have only limited gear changes in my leg/foot so it means i can ride  longer and change when i want to , not chug around ... Not so well today but hopefully tomorrow I can take a peep at the sprocket clearence .

Yes, my apologies, you are correct I put down the down the wrong size should have been 16/45, going up three at the rear is equivalent to dropping one at the front.
I was replying to a trail bike forum query in relation to the Serow at the same time. Note to self answer one query at the time 
I will change the original to read correctly.
It is motorcycling which keeps our heads clear, but difficult to explain to those who have never ridden a bike.
Post how you get on with the 17 tooth, as it may help others

Did you fit the Kliktronic kit yourself?

[jackinacabin]

Hi , yup fitted the kliktronic ... simply threaded two holes and attached a bracket to the front sprocket cover and it works ... a bit heath robinson to look at but it functions well .... The 17 is fairly close  but not so bad when looking straight on . It fits with the origional chain with slack to spare , i now wonder if an 18 would fit . the chain looks like it will accomodate and although it would be even closer to the clutch rod it would still miss by a couple of mm which is enough ... looks safe enough to me  , not a hint of any fouling with the 17 anyway .... havent tried it yet . Knackered from all the messing about . Also raised the bars and put braided hoses on the front today ... so a success ful afternoons  messing about ... In summary 17t seems cool , I think 18 would also work but that would be as tight as i would wish to go ... any more and as you say the gearing would be too compromised as well as a potential for damage of the clutch rod ...

unfortunately  I have the  older thinner  sprocket nut on mine so looking for a replacement if anyone knows where to get the thicker safer ones ....

Thanks for the link , I wish I had been more patient- I went and bought the same on flea bay for 3 times that price ...
   Had a short blatt and turns out the 17tooth runs like a beut but still want to try the 18 ... much more chilled ride with nutter on tap at the higher revs .. best of both
