The chain guide cage (outer frame) p/n is 20-05401, and the chain guide rubber (inner liner) is 20-05400.  Both are 2013 MX parts, available separately from the chain kit.

Thanks Ray. Will start looking.

BTW,  I installed a rear trial-enduro tire (Pirelli MT43), which is much larger in diameter than the stock IRC tire.

Tried Spacers to lift the rear mud guard, but it was not enough. The best solution was to mount the entire mud guard few centimeters to the front. Drilled new openings for the bolts. Works great.

I have the rear 65T sprocket on its way from Sprocket Specialists, and few Martin 11T front sprockets on their way as well.
bought the chain guide, so only missing the chain.

looking for the less noisy chain possible. do not ride a lot, so longetivity & strength come 2nd.
what would you suggest I choose - standard, O-ring, X-ring...? all 520 of course.

[Keith]

Standard is probably fine. I was surprised that the X-ring sound was almost the same as standard, but the rollers are the main source, not the pins. O-ring is wider and will rub in the guides more. Alignment is very important, the large rear sprocket magnifies any error and the sound is greatly affected. Use a chain alignment tool, don't trust the swingarm marks. Lubrication also makes a big difference.

Thanks. Is that 108 links?

I suppose the alignment for chain operation may be affected by the tightening of the axle nut as well - for belt alignment the trick is to align it to the inside of the rear sprocket with a snug axle nut, and the tightening of the axle nut to spec (75lb-ft for 2016 DSR here) brings alignment over to the center of the rear sprocket.

Any comment from running a chain, how does torque on the axle nut play into alignment?

I'd suggest 110 links, Oded.  I used 108L with my 10T & it was slightly too short (the chain fits, but the tire rubs against the shock protector).  If 110L is too long you can always remove links.

Thanks. Probably a standard or x-ring  520 with 110 links is what I am after.

Anyone know the dimensions for the 2017's?

what size splined shaft is used, what are the Various dimensions/clearances to use for the larger chain size?

Perhaps a larger size that fits the same shaft that I could machine down?

What kind of riding you do? Perhaps not necessary with the wider belt?

[42Cliffside]

it's not That wide, anyway that wasn't the question.

On my chain bike, full-spec axle nut torque doesn't have any real effect on wheel alignment at all.  If it did, my alignment jig would throw a hissy fit, and that has yet to happen.

for those finding the information in this post helpful, here are the exact dimensions of the front 520B11T Martin sprocket (in mm)

[acacia1731]

Thanks for all the great info guys.  I've been following along, preparing for the eventual replacement of my stock chain kit.

One thing I don't quite understand:  If going with an 11/65, why not just order the whole chain kit and then just swap the front sprocket with the custom 11T noted above?  Seems like a lot of added effort to get a custom 65 sprocket and also buy the chain and guides separately?  I feel like I must be missing a detail somewhere?

In my case, if I already have the chain kit, can I just buy a stock chain and rear sprocket, and couple them with the custom 11T front?

[Keith]

Zero raised the price on the chain kit, now $325 and apparently does not include the lower chain guide. http://www.zeromotorcycles.com/shop/index.php?main_page=product_info&cPath=6&products_id=192 You can get a chain from KTM and a custom rear from Sprocket Specialists for way less than $200 total and easy to order, specs in this thread. Getting the custom front takes some doing. Also be aware that you'll need a dealer to recalibrate your odometer and speedometer if that matters to you.
