Is this the right O RING CHAIN /SPROCKET KIT

[Cati]

Hey guys,

Wanted to know if this is the right O RING CHAIN /SPROCKET KIT on ebay. I heard it wasn't safe to use o-rings chain but I have seen other Ducati owners with o ring chain. Please advise me on this subject.

I only use x-ring chains, but I'm sure others will chime in.

[Howie]

X ring chains are a little more money, but well worth it and probably cheaper in the long run.  As far as that fleabay add goes, the chain is what brand and model?  The sprockets are what brand, material and model?

[Slide Panda]

O rings are just fine. With the same care and use an x ring chain should have a longer useful life.

Regarding the eBay listin - I did spot any info on who made any of the components. I'd shy away from a batch of mystery parts

[Cati]

yuu, I was thinking the same thing mystery parts. I was looking for a nice CHAIN /SPROCKET KIT for my 2002 620 Monster. I think I'm going to go with the X ring after reaching online hands down haven't heard one good thing about the O ring plus I only want the good quality stuff for my baby. 

How about this

The drive systems kit (1st link) looks good. D.I.D. and EK are two of the bigger chain makers.

For the 2nd link, ca-cycleworks (a board sponsor) carries that sprocket but for about half the price. Though they don't stock one in the 620s stock tooth count. What they do have is SuperLite steel rear sprockets - for $39 up to 48 teeth.

They also stock a variety of front sprockets and suitable chains. Could always just go with them 

For the ebay chain I, personally, have not heard of that brand. No idea if they are good or rubbish...

[ScottRNelson]

I've ordered several chains and sprocket sets from CA-Cycleworks.  At least you can trust the quality of whatever you get there, and you can be sure that it will fit your bike.

[Cati]

Looks like the 2nd link. I seen ca-cycleworks.com website before but never check it out.

Should I be looking for something around  520 15/46? I would like to do wheelie but nothing to crazy.

[Slide Panda]

Stock gearing for a 620, depending on the year, was 15/46 or 15/48. There's a chart at the top of the ca-cycleworks page. Most folks with any make of Duc opt to change the final gearing for a larger rear sprocket or a smaller front. Like on my (05) 620 I ran a 14/48. The change to that vs the stock was a big improvement. Ideally one goes up in the rear, but +3 teeth out back is about the same as -1 up front. So finding a 50 or 51 rear sprocket isn't always so easy.

Even going to a shorter gearing set up like 15/51 don't expect a 620 to be a wheelie machine by along shot. Hell my juiced up 900 needs some good coaxing to lift off... granted in gear I'm probably 230 or so..ahem...

if you really want to play with the numbers in detail - here's a calculator.

I'm seeing I can put together 14/43 for my 2002 monster. How would the bike ride going lower then 15/46. I commute to work everyday in traffic.

Those combinations are very close to the same.

[Speeddog]

Those combinations are very close to the same.

For most purposes, they're identical.

15/46 will last longer, but be a little heavier.

[Cati]

What is a good size for a smooth ride for a 2002 620 monster?

What kind of riding do you do?

City?
Mountain roads?
Highway?

IMO you're over thinking it. I'd say go with the shorter gearing (14t or equivalent) and roll with it. It'll give you more access to lower engine RPMs w/o lugging the engine. If you'll be in slow traffic a lot it makes the bike easier to manage. Also it gives you a bit better acceleration which is handy for dodging spaced out commuters. Yeah it might be a bit more buzzy during long stretches of fast super slab (75 mph) but really not that bad
