I just tried the model KT-9661 rear and KT-9662. These tires are the latest addition to the company's product line and they claim these tires were tested and intended for motocross racing. Here in Canada, these are tires are about the same price as Kenda and Maxxis. They are definitely not as good. They are cheap; which is why I tought made them attractive in the first place. After two big afternoons of testing at my local track. I have come to the conclusion that I lost my money, no mather how affordable these tires were. My track contains a variety on sections that range from loose yellow sand, loose dirt to a gray clay that is hard as pavement.
REAR:
I found The rear was hooking up good in straight line on hard clay and did ok on hard packed dirt in straight line also. It really was not hooking in loose dirt and sand in straight line acceleration. What I found was not bearable was the fact that there was no way to stay on two wheels and bend the bike to turn. It would let go very badly all of a sudden as soon as you tried to lean over especially in hard pack and dry clay.
FRONT:
The front tire right from the start looks more like a good dual sport tire. I say that because the knobs are shaped to give a round profile and has basically no knobs on the side to support agressive cornering. I was not even sure if I should try it or not after receiving it. Anyway, to make a long story short, I spent much time planting carrots with my helmet visor. This tire is already off my bike. Actually, the rear also.
I hate to make a bad review, but I think the company has some more work to do. Hope it helps anyone. ;)
