Okay, I tested the Geckos today on my 400ex (which is completely stock). These tires worked great. They really hooked up, and didn't bog me down at all. I was able to climb all the hills that I made an attempt at. Plus, I was the only guy out there with these tires, so lots of people were coming over and asking about them. Everyone said that they look really cool....and I agree. All in all, I am very glad I bought the tires. Now it's time to modify my intake/exhaust system and give them a real workout!!!

 

Glad you like them. I am thinking of buying a pair as well. I only have one question, how do they turn?

 

The tires turned very well. I had no problem turning, and I'm using stock front tires. I really think that this tread desing is a good comprimise between a straight paddle and a v-paddle.

 

ya geckos work pretty good.
