Sprocket change for an old foccer
« on: 23 June 2012, 12:44:41 PM »
Hi - Time to change the chain and sprockets on my '98 FZS600 - Now before I get flamed too much  :)  when the bike was new I would have happily lowered the gearing for a bit more hooning but to be honest I am now in my mid 40's, planning on doing some euro tours later this year and find the current standard gearing a little too low for my riding style.


So I would appreciate any advice from people who have highered the gearing a little, what sprocket combo worked best? Did it dramatically affect the bikes riding characteristics etc


Any advice and feedback gratefully received

(BTW - Have already arranged to have the modified nut / washer fitted just in cases)

I did this and it appeared fine for a while until I rode with a passenger it also posed a problem when driving at very low speed such as when I "did" Wooton Basset when it caused me to stall a couple of times and needed to slip the clutch  quite a lot changed back much better. Hope that helps.

Thanks - What sprocket set up did you change to? one up on front?, not planning on having a pillion but will be putting some luggage on so may keep as std

if you not going to carry a pillion ,then you should be ok?.....up to a 16 on front will drop your rpm apprx 500..using std rear!!very good for motorways etc !.....it will cut your acceleration down ,but if you did start to carry a pillion and luggage etc ,like dx says you will struggle at low speed!!,and will therefore be using your gearbox more than normal!...and you dont want to be slipping your clutch alot?..for obvious reasons!!!!!!!!!!!!! :rolleyes

Take a look: www.gearingcommander.com.

I did the contrary and put a 14t front, to enjoy acceleration.

I am with CRH. The difference is about 500 rpm, but I did not notice a lower mileage with pillion and full luggage. Maybe it is just me, but I think it is because there is no need to open the throttle so much when overtaking or high slopes.

don`t want to be a damp sqiub about this, but i`ve always been a bit wary of changing sprockets (especially a smaller front sprocket ) as i have seen some very badly chewed up swing arms over time. happens pretty quickly too. just be careful and check regularly for any abnormally fast wear. Mr Yamaha put those sprockets on for a reason as does all other manufacturers. just my ramblings. ...feel free to tell me to rotate if you wish. cheers Ade
