Bonneville America Forums Forums Technical Forums General Tech chains and sprockets

I have got the new chain and was checking out the sprockets.they look good for 26,000miles, very little wear.I need some opinions. One side of me, says change them and the other side says they will be no trouble.I don't go on long runs any more and i don't abuse the bike.

If you are going to put a new chain on then put new sprockets on.

I just did my chain and sprocket set at 21,500 miles.....the set cost just under $200.....not a bad maintanance cost for over 20,000 miles....

The parts list shows a chain/sprocket kit with 42/16 (original SM) and 42/17 (original BA), but not sure if one is available yet for the current configuration of 42/18. I'm hoping it is available by the time mine wears out.

One of our guys was brilliant on the primary sprocket. Flip it over. The fishhook will be on the front side then. Replace it next chain cycle.

I looked at flipping the back sprocket as well as the front, but there is a slight offset in the back sprocket, so I didn't do it. The back sprocket is slightly thicker on the (original) outer side, but flush on the (original) inner side.

I always flip or change the front sprocket about every oil change. (Front sprockets are only $19 and are very quick and easy to swap out. Front sprockets should also wear out about 3 times faster than the rear sprockets, i.e. according to the gear ratios.) My chain and rear sprocket look like new, but then I only have 18,000 miles on them.

I flipped my rear after dealer sold me standard Bonnie sprocket (won't work). The offset difference didn't look like enough to worry about, especially considering how out-of-alignment my rear adjusters were for 20,000 miles. I bought an alignment tool when I changed my chain, my adjusters are a whole notch off. Chain is much quieter now. Wouldn't consider flipping front, too hooked. Can't be good on decel/engine braking.

Thanks Bob! Ill check the tech vault for the chain kit part numbers.

Here's a link to the TriumpheStore where they have the complete kits for $197.

Look near the bottom of the page and they show the original SM and BA part numbers.

I am going to go 530 with the Honda sprockets so I can just run a standard chain amd keep a chain breaker and master link on the bike.

I want to thank everyone for their in put. I'm on a fixed income and have to watch where and how my money is spent.THANK YOU ALL very much!!!
