I agree with 2wheelsforme that the tire looks worn in some spots but not others AND with only 6700 miles on the tire??? I'm not familiar with the Metzler 777 but I've run 880 and 888's on Honda VTX cruisers and the wear was even. (EDIT: The wear was even...all the way around the tire on the left side more than the right side.)
First, all of my information comes from this GREAT write-up on tire wear of motorcycle. I also recommend Tires 101 from Bareasschoppers which links to the other site I provided. I think BIGLRY is even referenced on the site a few times.
In a nut shell...Normally, ALL front motorcycle tires wear more on the left or right side depending on what side of the road you drive on and it's due to leaning the bike in turns at intersections.
Road crowning CANNOT be the issue. Think about how much of an angle the bike and tire has to be at for the worn part to come in contact with the asphalt! The wear at that angle MUST be caused by a left turn, and here in the USA, it's largely due to the larger radius left turns we perform at intersections. Over time the larger radius and thus longer distance adds up by. We drive miles more in a left angle lean then right angle lean. Also the lean angle creates centrifugal force at an ANGEL to the tire. The ANGLED force removes more rubber from the tire than when it's straight up and down on the open road.

Try riding the country roads of NE Pa. and you'll encounter "road crowning" you can't believe! You actually have to "lean left" to keep the bike up and that's no exaggeration. Depending where you live and what roads you ride and encounter has a direct impact on front tire wear as does the "road surface" i.e. fine/course macadam! Add in tire rubber compound and your have a varied receipt for tire wear/cupping. If tire balance was a issue those who use "BALANCE BEADS" and "RIDE ON" would never have cupping! If you follow the manufacturers instructions whenever installing the front wheel it states to "bounce the front end of the bike to align the axle shaft" and then secure the axle clinch bolts. That maneuver is missed by many riders who then receive less tire wear than anticipated!

The guy who invented the first wheel was an idiot -
the guy who invented the second one... he was the genius!

Low PSI can cause the sides to wear. Never heard of just one side wearing.
Look at the AVON's = they make a tire just for GW's = great service, great ride, great mileage. Google AVON USA & call their 800# for the AVON P/N.
Got F&R from Dennis Kirk @ my door for $299.xx. I really like dyna beads, 1oz F; 2oz R.
Close to 200K on 6 bikes in 19 years and on pretty much the same roads day after day. All tires except for 3 or 4 wore perfectly in the center. Even had one that wore on the right side instead of the left. They all got replaced before the tread was gone mostly due to those wear spots caused the tire to bounce a bit. And it if was road crown or turns would it not be even all the way around the tire and not just in spots?
Something to help you understand your front tire! The next time you install a new tire, leave the front of your bike elevated! Take a "cinder block" and place it on one end approximately 1/2" from the front center on the tire. Have someone slowly turn the tire while you take a piece of white chalk, rest it on the block and "ever so slightly" move the chalk so it begins to touch the tire ( like using a "Dial Indicator" on a round object! You will discover that your "brand new tire" is not "perfectly round"! Move the block to the side of the rim/tire and perform the same chalk test to the tire sidewall and then to the side of the rim and see what results you get! I'm betting you will be surprised at the amount of "run-out" you observe i.e. the chalk contact/test! This is coming from a "Old Motor Head"!
