I have ran the 777's on two bikes, first was on a 2007 Roadstar 1700 and putting 2 set on a 2013 Yamaha Royal Star Venture S. These tires stick like glue in wet or dry conditions. They are very quiet, very stable, very smooth and VERY responsive!! I can feel the road through the grips with these tires. I am 6'1" and 225 lbs and my wife is 5'7" and 160 lbs. and we are always 2 up, long distance riders and pulling a trailer. I am a very aggressive rider and run ALOT of curves on the Venture. The Venture is also ridden daily for commute. The front I typically get 14,000-18,000 miles and the rear (depending on how much we pull the trailer) can get 6,000-12,000 miles on the PREVIOUS version (non HD) excited to see the mileage on the HD before it starts cupping.
Just had the Shinko 230's installed on my 05 v-Star 650 Silverado and so far, they seem great. No shimmy, good stopping and smooth ride.
Have not yet rode in the rain yet, but I'm sure that will come soon enough. These tires replaced Bridgestones and for the price, how can not give them a try. I use the bike for commuting to and from work so 3/4 of the ride is highway and the other 1/4 is back roads. Other riding include the blue ridge parkway and back roads. Eager to see how these tire hold up, but the dealer I use recommended them and a customer at the dealership said he had a set and loved them.
The Shinkos I'm about to replace on my Triumph Explorer 1200 have 17,000 miles on the front and 9,000 on the rear. The front still has tread left after wearing out two rear tires, but it's cupping a little. The rear has worn very evenly but is now down to the wear bars. Traction and handling is similar to MUCH more expensive tires, and longevity is better. Best buy available!
