Primary Drive Chain Roller
Brad in MN
Bolt is too short for YZ 125
All is good except the bolt that came with it is too short for the YZ 125's. Still less expensive than OEM even with getting a different bolt from the hardware store, just a little extra hassle.

Tusk Aluminum Pro Handguards
A in ME
Reason 1 star, have to to submit. Product not deser...
Garbage. Does not fit 2018 wr250r. Left side fits as it should but right side is impeded by the reservoir line. I dont believe theres a way to install incorrectly. 3 options- 1- rotate the brake too far down 2- rotate the guard far too high 3- flip the bar mount upside down and its pretty spot on just looks super clowny.

Yamalube Performance Semi-Synthetic
Justin in CO
Great value
I run this oil in everything I have because it is a great value for price and protection. I change oil in my 450FX most often and it never smells burnt or looks broken down.

Works for well made bikes.
Don't buy if you have a garbage ktm they simply suck at everything. All other bikes I own this worked perfect. Sold all my KTMs they're over priced garbage.
