Anybody have experience with these tires? I think they are standard equipment on the DRZ-400S.

 

I have a DRZ400S and I believe those are the tires. They are commonly referred to as "DeathWings" because some people have wiped out in wet grass or mud or loose soft sand. That said, I have 800 miles on my bike and I haven't wiped out yet (I probably shouldn't have said that...). I like the tires on the road and so far on hard pack fire roads etc they are fine. They are a bit squirrely in gravel and even more so in sand. I haven't road in any rain but have rode on wet roads after a rain and didn't notice any problems. I will run out to the workshop and verify the numbers for you so we are talking about the same tires.

I have them on my XL600R. They do fine on the road and on hard dirt but really suck for traction in wet or muddy stuff.

 

Just checked and they are the TW41 and TW42 tires I have. They corner quite nicely too

Hmmm...squirely on gravel...that's my biggest complaint with the stockers...guess I'll spend the money on the tkc80's or the tw301/302. Thanks guys.

 

I had them on my Serow. Very hard compund. It looked like it would last 20,000 miles.

 

Yeah, I'm not all that concerned about tire wear as I am loose gravel. I road a lot of trail in NM that had a lot of loose rock and gravel and the stockers were all over the place.

 

Yeah if you want that controlled floating effect on loose gravel you want to go with something a lot softer and knobbier.

 

You might try some rim locks on the stock tires. Ijust did this so I could run the tires down to 10psi in the mud.I'll have a report after this weekend.
