after coming into contact with many brands here is what i have found to of great quality, but im not commenting on premix or tranny oil:
BelRay waterproof grease, and chain lube. like Aids for your chain, not even Magic gets rid of it.
All Pro Honda products, they have some mean cleaners and fluids
Silkolene ProPrep, thats stuff is the shit for plastic. looks better than new, really restores the luster.
VP fuels, duh.
Toomey
Wiseco
LSR
Vito's
ProTaper
Two Brothers racing, not sure if they make banshee stuff, but they have a Protaper bar kit for an XR50. thats get my vote.
Engine Ice -
DDI - wicked shit at a good price.
that about all i can think of for now.
feel free to add some.
