Rear sprocket studs ,and portable tire inflation questions

Bill Hilly · 06-18-2021, 09:27 PM

I have had no trouble from my Brozz, but I know that they can sheer off the rear sprocket studs , and if replacing them with better ones can prevent it, I would feel better doing it before they fail if they are really as bad to sheer as what it seems they are from what I gather. What are the proper replacements for the studs? I would also like to hear your thoughts on compact tire pumps. I see several varieties"and styles on Amazon. Thanks.

Someone will correct me if I'm wrong but I believe they are the same as a Honda CRF230 or the XL175's. (the good ones) So, google or go to the Honda motorcycle dealer.

The ebay/aliX versions can be a bit on the fudgery side of things. I got a set of the cheapies for my XL185 and had to use some washers to compensate for some side play sprocket slop, Could be my cush bushings though... Also try to get the ones with flat sides, not the all rounded versions.

I stick to OEM Honda replacements where possible. 90128-ke2-940 is the part number. I order mine from Partzilla https://www.partzilla.com/product/ho...hoCjuIQAvD_BwE

A good serrated flange grade 10.9 Metric nut from the hardware store will do just fine on the other end along with some blue loctite to make sure they stay in place. (The OEM Honda units come with the factory Honda Green (Equivalent of blue) on them already.) Torque to 30-35lb-ft.

All of that being said, I haven't heard of too many Brozz owners having an issue with theirs. Usually it's just the Hawks and I think 2 TBR7's that I have seen have a problem. I am not saying it isn't worth doing for peace of mind though.

I had just assumed that if the Hawk had the issue of breaking them ,then the Brozz would as well. I never intentionally abuse my bike, but I think I have operated it for a while when I first got it with the chain too tight. I was mainly wanting to reduce the risk of being stranded . If I don't have to replace the studs' then I would rather not. I just thought that they were bad to break, and it was just a matter of time before they broke. Thanks

In that instance I would say if/when you have to replace the rear sprocket it would be a good idea to replace them with the OEM Honda replacements just for peace of mind, but I think the Brozz has better quality units than the Hawks from the factory. I may be wrong, but I have yet to hear of a single Brozz that has broken any.

Yeah Billyhilly, you started to get me all bothered about my own Bashan, LOL...so I took a flashlight to my sprocket/studs...and they looked pretty dang good! I'm going to just assume it is a defect that only happens to Hawks! Haha! Also, Megadan's correct... I also saw those studs on the Partzilla site.

Aren't the Hawks & TBR7s post & forum members more prevalent on here though? Per caipta I mean? I may be wrong.

The partzilla sure has a better price than Amazon! $5+ compared to $19+.

As far as tire pumps, I carry 4 small CO/2 cylinders and a CO/2 inflation tool.. that's enough to get my tires back to street pressure after off roading.. compact and quick.

Where'd you get that awsome idea?

Sorry to resurrect an old thread but the rear sprocket studs sheared off on my son's Brozz today at around 4k miles. Luckily was able to get home using an allen wrench tied to the sprocket to hold in place. Will have to order the Honda replacement one now.
