Larger rear sprocket

[Retsel_imp]

If he can figure out the factory part number from a non U.S. 900RR- it had a 42t that would fit. U.S. had a 43t and I can’t find the part # for ROW

Got it. Let's see how he responds and I will ask.

Takahashi's response,

Thank you for the inquiry.

Regarding your question, I am sorry 42 tooth is not available, but I can get 41 tooth rear sprocket. 

I wrote back and asked about the 900rr sprocket. We'll see.

Found this on the JT Sprocket site. I think it's what we're looking for. Need to check the measurement.

Think I figured it out. JT has the same part number, JTR302, for all the CB1100 Models. So it has to fit! Found it on Amazon

Amazon.com: JT Sprockets JTR302.42 42T Steel Rear Sprocket : Automotive

Placed order. Should be here around the 9th.

I know the 900RR application will fit- I just don't know JT sprockets or their quality.

The Sunstar I tried is the same company that makes the factory sprocket on our bikes.

I would still love to find the Honda factory part # for ROW 900RR 42t sprocket. My google fu is failing as I have not been able to find it.

 

[Retsel_imp]

Well, returning the sprocket, bought from Amazon, I have been informed that the supplier, Powersports911, will be contacting me. When they do I will ask if they have the 900rr, international, 42 tooth sprocket from Sunstar.

I did check reviews on JT. Didn't see anything alarming. Here's one, JT Sprockets review

Powerdubs,

From my searching it looks like the 900RR came with a 43 tooth?

I found a post on a Fireblade board that the (at least) ‘94 Austrailian bike came with 42T. And I found this: REAR WHEEL - Honda CBR900RRR | Honda CBR900RRR 1994 REAR WHEEL with fast delivery to United States | Fowlers Parts

Funny looking part number if this is it: 41200MW0000

Hope this helps.

 

[PowerDubs_imp]

Pop- the 900RR came with a 43 in the U.S.- 42 rest of the world.

Which given the size of the world- blows my mind the part would be impossible to locate...??

 

[Lord Popgun]

If that is the part number, maybe Cormanus could check some of his sources...
Or just check them as I guess they can look it up.

 

[Cormanus]

Try 41201-MEL-D20 for the 2003 CBR900R.

I’m not sure if the 2003 uses the same part. The 900RR generation that would fit is the one from the early 90s 9394 etc..

someone find me a 37 tooth for less than $60. the JT is aluminum. I'm not paying $60 for an aluminum sprocket. if it was steel I would pay it because it would last.

OK, there are two offerings for the 1994 CBR900RRR:
[ul] [li]"Sprocket Comp., Final Driven (42T) P/N 41200-MW0-000"[/li] [li]"Sprocket Final Driven (43T) P/N 41201-MAL-600"
[/li][/ul] Again, check the parts fiche here. Peter Hill seems to have a good historic parts list. For what it's worth, the 43T sprocket part number matches with that on PartsFish, although there is no 42T sprocket there. Makes me think the P/N is probably right. Mr T could get it, maybe, if you can't source it locally.

 

[PowerDubs_imp]

Thanks. Appears to be discontinued. I guess I'll just order the JT sprocket one above.

 

[Cormanus]

Have you tried Mr T?

 

[PowerDubs_imp]

No, but if Honda is listing it as discontinued that is different than him just tracking down a foreign part #.

Also- it appears that even when available, the cost was 5 times the cost of a comparable aftermarket part which is insane. A little more cost for a little more piece of mind- ok. But not that much.

 

[Flytech99_imp]

If the early 900RR sprocket is compatible with the CB, are there any quality 42 tooth aftermarket options for it? Maybe cross-referencing to a different model will yield better results than the CB. I’ve seen that before with a few other parts.

That's exactly what we did with JT Sprocket. This is the result. Same part number for CB1100 and 900RR.

Gotcha! I looked at that page wrong the first time. I see now the part number is the “same” although the number of teeth vary based on application.

 

[PowerDubs_imp]

Yup
