Thread: Rear sprocket

Took Honda Phantom, done 27k, for a service. They told me it needed a new rear sprocket and quoted me 3420 Baht. I'm not a bikey person but I thought that a little expensive. I've tried googling the price of one but can't find it. Can anyone tell me if that is a fair price?

BTW - I'm wearing a corset to stop my sides splitting from the 'buy a real bike' gags that will also follow.

Maybe its for a chain and two sprockets but even then I cant see them using a expesive chain on a Phantom

The chain is less than 6 months old.

Yeah, I'm going to take it to a few other dealers and see what they say. Before I buy anything here, I like to have researched the price of the products first. I used to be able to get onto the Honda Thailand Motorcycle online catalogue but now I can't find it anymore.

I had the front and rear done on my VFR, can't remember the cost now sorry but it was most certainly cheaper than what you've been quoted.







Ps. Get a real bike! Not a corset-strainer sorry, best I can do on short notice

If you're running a new chain on worn sprockets you will wear out the chain prematurely and vice-versa.

I've always been of the school where you replace both sprockets and the chain as a unit.

What would be the expected life span of sprockets?

I would guess a couple of years on a Phantom but it real depends on how you ride it and how well you keep it lubed.
I lube my sports bike chain nearly every time I use it and change my chain every 12 to 18 months mined you I am hard on my bikes and do burn outs and wheelstands every now and then

On a Phantom you should get in the 15000 km range out of your sprockets.

If you need a new rear sprocket it time to change all three front sprocket and chain as well. The chain will the stretched to mate with the old sprockets.
If you use that chain with the new sprockets it will shorten the life of the new sprockets.
Also getting the highest grade(quality) chain you can get is money well spent. A quality chain will prolong the life of the sprockets, need less adjustments and generally less hassle.

Thanks guys. I'll go for a full chain and sprocket replacement

Buy a can of chain lube while you are at it, might be called kettenspray, something like that, it is German. and put in on every so often, Thai do not believe in grease in bearings or lube on a chain, and if they do happen to do it, it will be used motor oil that will just fly off and make a mess on the bike.

I never lubricate a chain, I use "o" ring or "x" ring chains they don't need it, their lube is built in, but they need cleaning. The best thing for cleaning is a good soaking when the chain is hot, in motor oil, if you do it when you come back from a ride there is little to fling off the next time you use the bike. Look at the manufactures manual, I bet it recommends motor oil. The fancy spray on lubes do bugger all except maybe inhibit corrosion.
On my touring bikes I used Scott oilers, a chain will last for 30K of hard riding but its the constant cleaning action that keeps it going.

How long does your rear-tire last ??

the last set of BT 014 lasted 2k but now I have BT 020 so I hope to get a few more out of these

Motor oil is fine if it is an oil bath chain, in a case without dirt it will last forever, like the one Harley had on the cruisers from 80 FLT til they ran the new frame in 84, then quit that and went to rubber drive in 85.
"O" ring chains do need no oil, you are right, but the chain lube does stick to the chain and sprockets and will run down into the rollers before the lube sets up if it is just a regular roller chain and not "O" ring..

Facts you should no about Motorcycle Chains!

I run a RK X ring and still lube mine

Even a X-Ring chain seals have to be lubed occasionally to keep them from drying out & help flush grit off the chain!!!!

Anyone know who sells PJ1 Blue Label chain lube

its just another rip-off price, as you are a farang
tell them to go fuck them selves --
a rear sprocket isn,t the soution btw
you need a front sprocket and a new chain
circa--1000 bht would be ok

tip--put lots of oil on said chain , that way you will get lots more miles out of the rear drive

If you talk nicely to the dealer, he can fit a locally-made set of parts for around THB 800 - front, rear & chain.

I had to go that way when the local parts for my Honda CBR150R were not available anywhere in Thailand at that time.

They work just fine.

What a load of crap
Just shop around until you find a decent dealer and use him

^ Wishfull thinking........mine last about 3500km, and I thourght that was bad...

My bad, is was a respond to your rear-tire..

^ Just wait until it comes back. It will be as tight as a banjo string.


I was alway told that it's best to have two chains.

Once you need to regrease/oil clean it in petrol then let it evaporate off then put it into a can of grease and heat the can gently for an hour athen hang the chain up to drip over night.

use your spare chain whilst you wait.
