I'm putting on my 5th set, replacing my 4th set of Shinko 777 HD's on my Ultra. These tires are incredible, at any cost! But the price is a real bonus! A set of tires, WWW at that, for less than the price of a rear tire at the dealer! That equals a lot of extra beers in my belly!! Another plus!! I get 6500 - 8000 miles on the rear, 2 x's that on the front. (Actually, I can get 16,000 - 20,000 on the front, but don't want to get down into the 'body' rubber on the tire). I do a lot of touring riding, 15,000 - 18,000 miles a year. So, 2 rear tires to 1 front tire, that's the way I order them, 2 rear, 1 front, then I'm set for a while. The grip is great, dry, wet, riding in the rain, no worry, great grip! The WWW are excellent! Get a bottle of Bleche-White whitewall cleaner, follow the directions, they will stay just as white as new until you wear them out. Don't wait 6 or 8 months to clean them though! Like anything else, they will stain. BTW, the HD in the tire description does NOT stand for Harley-Davidson! It stands for Heavy Duty, i.e., heavier sidewall. The 777 HD is designed and fabricated for large baggers (touring bikes) that generally carry a load, 2 up, clothes, gear, etc. Heavy Duty for heavy loads on the highway, lots of speed, lots of miles. If your riding a bagger or other large bike mostly around town or on short trips, you may find the 777 (not HD) to be a better match for your bike. Lastly, don't look at the 777 as a 'cheap tire', it isn't! It a well engineered, well designed, well constructed tire at a great price. Try them, I know you'll like them!
