I have run both 13/48 and 13/47 with a fresh MT43. I have settled on the 47 when running mostly doubletrack with a decent percentage of street riding. The 48 is better in the gnarly singletrack but feels wound a bit tight on the highway.(I could go slower I guess) It also tightens the range between gears, most notably between 1st and 2nd. I will be going to 14/50 when this is ready to be swapped out.

I think I'm pretty happy with the stock gearing with MT-21s. I spend most of my time on trails in 1st gear. I don't really have a problem crawling through slow stuff and I like not having to upshift when climbing hills. A 45T in the rear might be okay, but I wouldn't want to take too much off the top speed in 1st.

if 14/48 seems wound out...why change to 14/50? wouldn't that be eve more wound out? or you planning less highway, more gnarly ST?

One day this winter, when my bike's apart for maintenance, I'll take a picture of the grooves in my Sandman case saver that came from running a 14T front sprocket and I'll let y'all decide if it's worth running. I'll never run a 14T again.

With an MT43, I'd run 13/47 or 13/48 since it's a REALLY tall tire, and then run the chain longer so it doesn't contact the swingarm. i.e. with a 13/47, run a 112L instead of a 110L. 112L should cover the 13/48 too.

On the middle sized D606, 13/47 is about perfect for all around use.

On a stock sized tire, 13/45 works great if a little short on the highway for lots of interstate work. I like the 45 rear on my X now that it's running a 150/70/17, but for all around use the stock 42T and 43T worked great with a stock sized rear tire.

Your chain is too loose

I run a 14t sprocket and a Sandman Case Saver with zero issues. I run 14/49 sprockets and adjust the chain by deflection measurement.

This is hard to explain in text. Both of my sprockets are larger there by increasing the chain distance from the swingarm (top and bottom). If a proper stock gearing adjusted chain is say 10mm from the swing arm with x amount of slack taken out of the chain (pushed up towards the swing arm) When you increase the size of the sprockets you increase that distance, 10mm goes to say 15mm. If you keep it at 10mm with the larger sprockets your chain will be looser.

That is probably as clear as mud..... regardless I have not had any wear on my sandman case saver, and only typical wear on my slider (compared to your avg dualsport, not just WRr)

He said 13/48 and 14/50. The latter should be very slightly higher gearing.

Once again, the discussion has focused on the diameter of the front sprocket as the cause of slider wear. My 12T front and lack of slider wear suggests otherwise to me.

As I have posted before, I think this is a more complex issue, caused by a combination of factors, a "perfect storm" if you will. A worn, kinked chain, perhaps combined with a heavily loaded bike, perhaps combined with improperly set sag, and maybe a too-tight chain, AND in some combination of these all at the same time.

I already have my next sprockets, and I will go to a 13/47 (currently 12/43), because the logic of moving the chain further from the swingarm is undeniable. The reason I will do so is because it seems sensible & logical, but I have not had any issues (yet anyway) running a 12T front.

Thinking a 14T front is the silver bullet to eliminate slider wear may lead some to think "problem solved", and perhaps to damage a swingarm due to decreased diligence in inspecting the chain, sprockets and slider.

Here's a couple shots all loaded up to go to Cambria for Horizons Unlimited get together and then followed by trip to Copper Canyon in a couple weeks. It looks pretty good without all the gear hanging off it also.

I understand what you're saying, and maybe it was due to having a somewhat loose chain though I also go by chain deflection.

Regardless, the amount of wear on the chain links and the chain saver itself convinced me to not run that sprocket size again. I've had good luck with my swingarm guard over the years, and only get wear on it when the chain gets old, kinked, and dirty, chain tension and whether or not the bike is loaded or unloaded doesn't seem to matter nearly as much as the condition of the chain itself. I'm sitting at just over 43,000 miles and have gone through two sliders, both were with 12T, 13T, and 14T sprockets on throughout their life.

Well I never carry a HD tube for a spare (but I run one) so you may have a point there.

Have you actually ridden with the tank panniers loaded up? I tried them and it was a pretty awful failure. Velcro adhesive proved insufficient, bags started moving around, then beating me in the kneecaps. Roadside fix involved straps around each bag, connected to each other over the steering head. They're great for holding standard nalgene bottles though, if you can make them work.

It might be helpful to note compression and rebound settings when reporting chain wear...

I just switched to a soft compression and a slow rebound on both front and rear.. in an attempt to stop a wear issue...

I did have soft compression and fast rebound and the rear swing arm was much more active than it is now...

Looks like you could leave in the morning. Well sorted WR. I need to start getting ready, a couple of weeks is coming fast.
