Stock kits are available from Triumph. With care, 30,000 miles isn't unusual. Might cost a bit more but will fit. The front will have the rubber damper as well.

 

Pricing out a D.I.D. chain, Sunstar rear sprocket and J.T. front sprocket, you'll likely find that you're right where the OEM kit prices out, minus the lock washer and rivet link. I've used the OEM kit numerous times and have gotten 30K+ out of the majority of 'em. One less thing to think about.

 

Just don't get the cheapest spockets.

Ruined my last chain after 10tkm due super soft sprockets that were out fast and streched the DID chain :/. 20€ savings ended up costing new set :/.

 

I did the 520 Chain conversion. Wear has been exceptional...its quieter, lighter and a tad more SOP power. I was a doubter until I did it...there is a reason Triumph switched to a 520 chain. I did from Sprocket Center:

Do you have a picture of the sprockets they sent? The sprocket center page says "*Sprocket shape and size will vary depending on model, picture is for reference only"

Do they match the picture?

 

I went with Driven sprockets in 520 and an EK MVXZ chain thru moto mummy. I have a 2011 Thruxton and needed a thin spacer between the sprocket and locking washer.

 

FortNine has all sorts of stuff. I got an x-ring chain and both sprockets for less than $200, although the front one did not have a damper like stock. Just a few thousand km so far but seems to be holding up. How do you get a chain to last 8 years? My original was pooched after about 2, lol.

 

Mine is 10 y/o and still has this year left in it.

 

Age has little to do with chain life. Chain and Sprocket quality, lubricants, chain alignment chain tension and environment all effect their lifespan. I get the best milage out of quality name brand chrome plated chains and premium sprockets. Chains on the slightly loose live alot longer then slightly tight and are a lot easier on the sprockets. I clean the chain with chain lube...Rotate the wheel a few times and let the excess drain off. I then spray it down with white lithium grease..let the white lithium grease "dry" over night. When I see no more grease on the chain its time to maintain the chain again..about once a month. Chain adjustment are only made when changing the tire. I change Chains and sprockets every three set of Tires...30k...

 

Just replaced the chain and sprockets on my Speedmaster, silver sprockets and natural chain

JT Rear Sprocket- $37.25 amzn
JT Front Sprocket- 17.22 ebay
DID VX 112link - 101.00 sprkt cntr

 

I have 16K miles on an EK x-ring chain put together with their "EX Screw Link" (<--swipe, right click and google search). still working, no problems.
Now I wish I had replaced the sprockets at the same time. I will for the next one.

 

Someone else already recommended Sprocketcenter .com, I would like to second, or third or whatever that endorsement. I needed sprockets and chain for my KTM 990SMT and the sprocketcenter had a really good selection and even better prices on brand name aftermarket sets, even the dealer couldn't touch them. I looked up some Triumph Scrambler parts and they also had almost anything you could want at great prices.

 

Did almost the exact same thing as Duckman. Lost #'s, quieter, seems "snappier" and will likely last longer. Do 520!

 

Why would it last longer? Isn't durability the only negative to a 520 conversion?

 

A 520 conversion is a good idea and can be done cheaply. The last of the air-cooled classics ('15-'16) came with a 520 chain - the front sprocket certainly bolts straight on to all the earlier bikes, I have no info on the rear sprocket for those years, so may not fit.

If you want to go to a smaller front sprocket (15, 16, or 17T for more acceleration) and have access to a lathe you can turn down the outside surface of '98-'03 Yamaha R1 sprockets to the same thickness as the OEM ones. (If you don't reduce the thickness of the sprocket there's barely enough space to fit the locking washer...)

The rear sprocket on our bikes (43T) has the same bolt pattern as the '01-'05 & '06-'10 Suzuki GSX-R (42 or 45T) so bolt straight up.

A decent 520 chain is more than man enough for the job on our bikes - heck, even on my bike! The weight saving is nice and will, eventually, show up as improved fuel economy (measured long term - you won't see the difference in "miles per tank"). Stay away from aluminium sprockets - they are only suited for race/motocross applications where chains and sprockets are changed every race - the steel chain grinds the aluminium sprocket in a wonderful abrasive paste...

Ordered

I'd like to thank everyone for their input. I've decided to go with the 520 Conversion Kit - SUPERLITE RS7 Steel Sprocket Set from Sprocket Center. Not a bad price, though what I saved off the kit I'll have to pay in the exchange rate.

I had considered a belt conversion that was suggested in a private email, but in the end decided it just wasn't keeping with the look of the classic Bonneville... Maybe if I went to a big bore kit! :wink2:

Thanks again to everyone who responed.

 

The Satisfied Customer

So often these threads die out with no feedback or conclusion, so I figured I'd do a follow up.

As stated above I got the 520 Conversion Kit - SUPERLITE RS7 Steel Sprocket Set. I'm quite happy with it. 3 points I'd like to make.

The Positive. A day or two after ordering it I received a call from Sprocket Center telling me they didn't have the chain I ordered in stock. So they were going to upgrade my chain free of charge. The chain I ordered was more than enough for a Bonneville, the substitute is over the top for any perceived performance needs! Great customer service personally phoning me and telling me they were upgrading my order.

The Neutral. For whatever reason, I thought the chain came with a quick link connector. Nope it was a regular link that needed to be riveted. I didn't have a chain rivet tool. So that added 2 extra day's on by having to order it on line, as I couldn't find a shop open on a Sunday that had one. Seeing as I couldn't get to any shops the first 3 day's of the work week it was just as easy ordering it on line.

The Negative. This one in no way reflects on The Sprocket Center. The chain came coated in a thick sticky lithium looking grease that was near impossible to remove. Scrubbed as much as I could off of it before putting it on, and then with regular chain cleaner after it was installed. These things are meant to survive outside in the rain & elements, why does the manufacturer feel the need to put so much goop on it when a light coating of oil would have sufficed?

All and all I would recommend The Sprocket Center for quick and easy one stop shopping.

That is hardly a Negative unless you enjoy buying a rusty chain.
Next time, just mount the chain "as is" then use a rag soaked in WD-40 to wipe off the factory lube,
and apply your favorite chain lube.

Changed my front sprocket to 19T today.. wow!

The difference is unreal, it's like having another gear to go on.

Very easy to recommend it.

 

I am glad everyone is enjoying the 520 conversion. I have about 15K on it and everything still looks new. Actually I prefer the "monkey snot". Everyone has their own method of chain maintenance. I clean the chain with hardware store chain lube and let it drip dry. I then apply a heavy coat of spray white lithium grease...and let it drip dry overnight. My Chrome chain is white. It takes a really good rain storm or bike wash to wash the white off. Under normal wear and tear it lasts about a month. When the white is gone its time to redo. I use PB Blaster or Liquid Wrench Products. I am more concerned with function and durability then cosmetics. It works for me...

 

I got mine yesterday!

 

Stock DID chain and sprockets,,

 

My T100 has almost 12k miles on it. If I were to change a sprocket size, would I need to replace the chain as well? I wasn’t sure if there was a concern with the two “wearing in” together.

 

30K or 18,641 miles is just OK, chains are best for off roading but a 50 to 100 thou belt kit is the ****s, no adj after inital stretch, NO lubing + a clean rear wheel!!! only downside is initial cost + different ratios not readily available but cheaper in the long run!!!

 

12K aka about 7500 miles sprockets should be good if properly cared for, but be aware of chain sizing as sprockets are changed. smaller front aka ONE tooth may be ok but smaller fronts stress chain more, going bigger out back is generally better. i don't know WHY posters on forums use K that is kilometers, being in USA the clocks read in MILES!!! unless you really mean kilometers!!!!!!!!

K as in "thousand", as in 12 thousand miles.
