Case Guard recommendation for YFZ 450?

[trhode]

Just wasted a perfectly good crank case on an '04 YFZ 450 we just purchased. 1st day riding, chain failed and chewed right thru the case. Stock case guard did nothing. Which of the aftermarket case guards offers best protection?

UPP

/thread.

I don't care what anyone says, UPP are the best. They are made with the really hard poly plastic, and they are huge. They aren't just a little sliver of metal next to the sprocket. Most of the guys that I race with use them and swear by them.

Also, UPP makes it for Moose Racing, so that will work too.

I believe TM Designworks makes one as well but their co. is a joke.

UPP is the only one i would trust 100%.

Just ordered a UPP/Moose, I heard they are the best plus if one of your case saver mounting bolt is broken like mine it offers another a third hole to mount with onto the stator cover.
