Acerbis Chain Guide
Jason in ID
Simple, but probably necessary fix.
Installation was a bit "fiddley", but not bad. Fit was perfect. Time will tell if it holds up.

Acerbis Chain Slider
Ky in BC
.
I bought it just for the colour but still a good product the only part I didn't like was that the easiest way to put it on was to pull the sprocket off

All Balls Chain Roller
Daniel in LA
Long lasting quality
This is my third one in 17 years of hard use. Not sure when the factory one failed and I replaced it with this but I just replaced it a second time. Almost 24,000 miles with a fair amount of off-road mixed in. These things are bulletproof!

Primary Drive 520 ORH X-Ring Chain
Jeremie in CO
Good budget chain for longer milage between changes
Great budget Chain. Worked way longer than stock chain. Seems to last longer on 2T than a 4T when it comes to chain stretch and durability.

Excellent quality and long life
My DRZ is 17 years old and I've used Primary Drive products exclusively. I've never had any issues and get long life from their products.
