Gentlemen, After a stupid fallover while sitting at rest on my DRZ, I can honestly vouch for the integrity and usefullness of the ThumperTalk DRZ-400 case guards. One word. BUY THEM! After I lost my balance while talking to a neighbor at rest and sitting on the bike, I looked at the left side case guard of my bike where it meets the shift lever and low and behold there was a dent in it! Thanks to those guards, I can walk away with just a bruised ego and no hole in the magnesium side cover on the left side of the bike. Thanks for the idea ThumperTalk! Gregory.
