I am currently on my first pair. I bought this tire because of the reviews for longevity. I commute 52 miles every day, 5 days a week. I have put 5k miles on these tires and can put in a honest review. I installed these tires by hand - im sure you can you tube this. They are easy to balance. The grip on these tires are a 8 for daily commuting. The tires will give you a fair warning when close to losing grip and are predictable. They are not as grippy as soft sport tires but are not meant for track days. The tires grip better once worn in, make sure you practice emergency braking.

The tires do heat up quickly. The tires are also awesome in the rain. I had no problems riding in heavy rain. Just excersize due caution.

These tires are awesome for commuting. The tires have plenty of tread and I should be able to easily get another 5k miles on this set.

I use Kenda Challenger K657 on the front, and have been extremely pleased with the grip, handling, and treadwear -- both how many miles, and how evenly it wears -- on that tire.

I ride a Suzuki VStrom 1000, and unfortunately, there is no 150/70-17 in the Challenger line to use on the rear of my bike, so I have to look at other model tires.

I've bought 2 of these tires back-to-back. I like the Cruiser K671 rear tire pretty well, and they are, generally, a pretty good compliment to the Challenger. I have precisely zero complaints about the wet or dry handling (a big issue for me b/c a Shinko Cruiser tire threw me down in the rain crossing some rail tracks!) and the grip is completely satisfactory for how I ride the VStrom - like a middle aged guy on a high-mileage sport touring bike... with the emphasis on touring, not sport.

My only complaint is that when they wear, they wear unevenly -- they scallop around that central triangle shape, which is super-weird for a rear tire. When it scallops, it makes the bike handle a bit squirmy, and it wants to follow grooves. It scallops before the tire is fully used-up in the middle, too, so it always feels like I'm wasting 1000 miles. I'm currently replacing it at about 5000~6000 miles... not bad, but could be better if they wore evenly.

Got the tire went and put it on and they balanced it. Everything was really well after the balance looks great rides well but it did take them sometime to get the tire balance. They said it was because the way of that it was packaged. So the only thing that I can say badly about this is they should really watch the way they package the tire as it causes creases and will cause the tire to be out of balance or wobble if you aren't careful. The tire itself is decently put together and I have had it on my girl's bike now for almost 2 months. Works great and doesn't have a flat spot even though we do a lot of highway riding. All in all I recommend this tire as long as you have somebody competent and balancing a motorcycle tire and putting it on

I was happy with this tire, good traction, easily mounted, good balance and delivered fast too. After only about 400 miles I'm noticing "cracking" on the tire. Not sure yet what it will lead to as far as longevity but it's a little concerning. More updates ahead.

So far so good. Changed from Bridgestone to these and they work so far. Haven't had chance to ride in wet, or any other adverse conditions yet, but I'm happy so far. But I have put a few hundred miles on them since changing. Update. I've ridden in the rain now. They tend to lock up easier in the rain, but I'm gonna buy them again when I wear them out.
