Sprockets, sprockets, sprockets. - Pterodactyl_imp - 06-11-2015
Today, in full post-rally depression, I went and looked longingly at Last Blast. I won't ride it until I do some work. Have to do a major service, change the chain and sprockets, and replace the rear tyre. Sprockets are proving to be a problem. OEM from the local dealer were quoted at, in total, AUD205. So the answer to that is an aftermarket. I have been looking at JT sprockets. They (JT) don't have 2010 CB in their catalogue, but do have sprockets for '13 onwards. I surmise that '13 sprockets will suit the '10 model. A set of JT sprockets will cost AUD 90. So my plan is to rip the old sprockets off and measure them up against the diagrams provided by JT. If it looks good I will buy.
The JT part numbers I have are:
JTF 339-18
JTR 302-39
Any advice would be welcome. Both as to the sprocket choice and the work to be done. The work should be straightforward but I'm always willing to learn. I will probably change the chain slider while I'm at it. I did the brake pads recently so all OK there.
Cheers.

Let me see if I can figure this out for you. Do you have access to an online parts fiche? Get the stock part number for the sprockets.
This is for the 2013.
41201-MEJ-000 SPROCKET, FINAL DRIVEN (39T)
SPROCKET, DRIVE (18T)
23801-MAZ-000

Thanks Randy. I will attempt to get the Honda part numbers. The parts counter that I spoke with seemed even more confused than I was. The CB wasn't a big seller here in OZ and was discontinued with the '10 model so it has seemed to drop off the dealers radar.
Cheers.

Any thought to changing the gearing Ptero?

While I usually use OEM parts, these sprockets really look interesting: https://www.supersproxusa.com/our_products_stealth.php
You can have almost anything made: https://www.supersproxusa.com/Products/made-to-measure-special-sprockets.php
I had one on my KTM 300 XC-W and it showed no wear at all.

Took me a while to find the drive sprocket. In their infinite wisdom they have the drive sprocket, chain and rear sprocket all on different fiches.
Front sprocket is #16

Rear sprocket is #2

Chain is#2

Front sprocket is #16

Rear sprocket is #2

Chain is #1....OUCH!!

I'd be willing to bet that the front sprocket part number change is most likely just due to different suppliers and they should cross over with no issues. The rear sprockets are the same part number and therefore they are the same chain type. I have no clue as to why they are charging yopu guys so much for a factory chain....WOW.

No 'Birds, I'm happy with the standard set up.
I've done some research on part numbers and the '10 numbers are:
Final driven:
41201-MEJ-000. This is identical to the '13 model.
Drive sprocket:
23801-MEJ-000. The '13 differs slightly, 23801-MAZ-000.
I feel reasonably confident that if I order '13 sprockets they will suit my '10 model. I will measure up first though.
Xyzzy, I also normally prefer OEM but at 100% markup from the Sydney dealer 'No thank you'.
Thanks Randy and all.
Cheers
Randy, not only is the chain price painful but the sprockets, as compared with, for example, JT, are also expensive. Why? Well I guess because they can.

P,
I would go OEM in front:

Rear sprocket is a toss up, my stock was out of round.
The 13 is going to fit your 2010. The front is rubber damped and less vibration. If you have a problem getting it in the US let me know and I'll send it to you.
DID make great chains just get the pitch and links correct.
RE: Sprockets, sprockets, sprockets. - Pterodactyl_imp - 06-11-2015
Thanks CIP, if I go that way I will PM you.
RE: Sprockets, sprockets, sprockets. - ChipBeck_imp - 06-12-2015
The factory rear sprocket is steel and quite durable. Most aftermarket rear sprockets are aluminum and wear out much faster. Aftermarket front sprockets are usually steel but they will not have the thick rubber armor that your stock front has. If you are not changing gearing, stay with stock parts. I have 3 front and 3 rear sprockets. To get a quality steel aftermarket rear sprocket that will last like the stock unit it will be about the same price as the stock unit. There is no aftermarket front sprocket that is built like the stock unit. Cheers.
