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.

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
Chris in TX
Great on KLRs
I have this chain on two of my gen 1 KLRs. Works great. Make sure you get the Eagle Mike prevailing torque nut to make swapping front sprockets easier.

Primary Drive Front Sprocket

Honda XR70 front sprocket
Dropped from a 15t to a 14t front sprocket. It helped the little honda xr70 get to speed wayyyy faster. Fitment was perfect and super easy to install. High quality product.
