Bonneville America Forums Forums Technical Forums General Tech Brent's front sprockets

Hi Guys,
how are the after market sprockets holdng up? At 36k kms, I need to replace the front, and the chain. The rear still looks good. Wondering how many of these are out there and what kind of life are you getting?
Any advice would be great,
Gerry.

I have the 18T from Brent, and it still looks brand new after approx. 11,000 miles.

36k seems a bit high for sprocket and chain life?

I've done 2 chain and sprocket swaps using Triumph OEM stuff and Brent's sprockets with a DID chain, and haven't noticed any difference in how long they last. Even though your rear sprocket looks OK, I'd change that out too.

Realistically though there just aren't enough of our bikes out there with tons of miles on them to get a good idea of which chain and sprocket combinations last the longest. There's also other variables to consider like how often you clean your chain, how hard you launch your bike off the line, etc.

and adjustment.

Thanks for your interest. Did you notice I said KMS... not MILES? The previous research on this forum that I did suggests 36,000 kms (approx. 22,000 miles), is fairly normal.
Thanks for your info,
Gerry.

Thanks, Derek.
So I can assume that Brent's rears are top quality, too? And did you get your DID chain from him? Seems to me his prices are about half what the dealer wants! I tend to aggree with you on changing the rear.......maybe the surface is just through and now it'll melt like icecream in Arizona!
On the point of cleaning...... maybe I should be embarassed, but I have never cleaned it. The vast majority of our riding is done on extended trips (a couple weeks, 5-6k kms at a time). So the old girl is lucky to get lubed every night in the motel parking lots, with buddy on the seat and me duck-walking behind him, never mind cleaning the prick too!! I don't feel it has changed the end result noticably. Very conciencious of tension.
Thanks for your help,
Gerry.

I agree with Derek. You should change both front and rear sproket with chain. That way everything is new and you won't mess up you new chain. My Sprokets still look great after 11K miles. Most of the posts I've seen on sproket and chain replacements show mileage between 20K and 26K.

I've yet to find fault with any of Brent's products, but I didn't buy a chain from him. I bought mine from parts411.com. Unfortunately they've since raised their prices from just under $100 to something like $125-130 for a Gold DID VM2. Next time I think I'll just buy the entire Triumph setup that comes with the chain and both sprockets from one of the online discount Triumph dealers.

I'd buy from the local dealer if they were any good, but I've always been treated 2nd rate there since I didn't buy my bike from them. The fact that they didn't even carry Triumph motorcycles until a year after I bought mine seems to be lost on them.

One thing that can be easily done to extend the life of the sprockets & chain is to flip the front sprocket over after about 10,000 miles. Most of the wear is always on the front sprocket. Flipping the front sprocket over is like starting with a new one, rather than forcing the chain to stretch over the worn teeth.

Thanks to everyone for all the info......
Tom.....thats a great tip, I was wondering about that when I took it off last week, I noticed that it looked reversable and wondered why I couldn't just flip it.
Does anyone think there would be a problem flipping the sprocket at this late stage, after there is already visible wear showing? And what about the rear? It looks reversable too?
gotta make a desicion pretty fast, I guess, I got daffys poking up and yesterday we even seen a robin!!
Cheers, Gerry.

Re GerryC

Have 03 America- Replaced chain at 35k and sprockets plus chain at 50k. The rear sprocket was still serviceable and would have done another turn. Have read in postings on this that the rear sprocket will do twice the life of the primary but I guess that depends on how hard you hit the joystick.

I have about 25k miles on my belt drive now, oh wait...you asked about sprockets.

nevermind.
