24 and 21. I have tried different pressures though. Talking with SlowJoe, he is under the impression that what is happening is someone in the factory is putting their finger on the tire prior to it being completely set. IDK They still work fine. They just scream like hell on the highway.

TKC80's are speed rated,,D606's are not.
I have never had a problem with either tire, but the 606's are far cheaper.
I run 32 rear and 26 to 28 front on pavement, and drop both 10psi for off pavement.

22psi on road 13psi offroad


My next dualsport is going to have an 18" rear tire, so I can just run real knobbies

Well my $0.02 would be the opposite. What I have read/heard/been lied to/personal experience is that Knobbies don't like high speed droning with a load and "low" pressure. Heat builds up and knobs flake off.

I tend to run high pressure at high speeds... and my own particular voodoo is to run them through some heat/cool cycles before I run them a long time at speed. I once spooned on a new 50/50 tire, rode it to the Alvord loaded with gear, arrived, chunks missing, checked pressure... whoops, low 20's. YMMV

My personal outlook is if I run a knobby at prolonged high speeds and get chunking or ride with street tires in the mud and crash.... well, I was asking for it!

Thanks guys, coming from a street bike background and running modern street radials I'd run 36F & 40R but with the dual sports I've been running 25 F&R. On this last ride I was at 20 psi front and rear. I was thinking I'd get more traction in the mud with less pressure. Somewhere, some time I was told that's as low as I should got without rim locks. I guess like most things in life, you places your bets and takes your chances.

For the type of riding we were doing last Sunday I was running 15psi Rear and 18psi front. If it was muddier I drop about 3psi on both ends. If it was rocky I go up 3psi on both ends.

Hmmmm running any kind of dirt, 13 is my max

I used to run the stock deathwings down to around 8psi on the rear without locks

I put rim locks on my DR front and rear when I started running knobbies

I was ripping out valves stems at 22psi on the street

Did Honda remove the rim locks..? My '04 650L came stock with one each, front and rear. My '95 came the same way.

YMMV on tire pressures. With the 650, I like to run a little more pressure (15 to 17 front, 12 to 15 rear) because I hate changing flats. My Montesa runs 4 psi in the rear and about 6 in the front .

Hmmm, Only flat I ever had on the DR offroad was from running a really rocky section without airing down and I punctured the tire on a rock. I think I'd been ok had I been running low pressure

On my '09 the rims are drilled for rim locks but it didn't come with them.

Or you guys could just call it good at 25psi F/R and learn to ride!

West about mid point of the ride you made a comment that still makes me grin. That was just after you'd rode your XR up and down the clay hill, you said after all the years of chasing the Sanchez brothers around with your KLR, you realized how much they were cheating by riding XR's.

I like to think of it as best utilizing the resources available to me.. . Plus, it's a proven fact that Honda riders get WAY more pussy than those KLR guys do!

That West guy has always been a bit over-inflated in my opinion.
