death valley on gripsters

Post by John Biccum » Sat Oct 14, 2006 3:27 pm

I use the 130/80-17 on the rear and the 90/90-21 on the front. The TKC80 tread pattern is quite similar to the D606 but the TKC80s outermost knobs are almost full width not half width like the D606 and the profile of the tire is more rounder than the D606s. You can see these two conditions in this photo of a well-used TKC80 front: http://johnbiccum.smugmug.com/gallery/497409/1/64708202 I suspect that these two differences account for the much better street performace of the TKC80. Not sure if the 140/80-17 would fit the rear or not, I have never tried that size. _____ From: Don S [mailto:dbs52a@...] Sent: Saturday, October 14, 2006 12:21 PM To: John Biccum; 'Ronald Criswell'; 'Jim' Cc: DSN_KLR650@yahoogroups.com Subject: RE: [DSN_KLR650] Re: Death Valley on Gripsters Hi John. The TKC80 has several sizes that would fit a 17" rim. What size do you use? Would the 140/80 - 17 fit? The tire sure looks a lot like a D606. Don John Biccum wrote: With D606s I usually get about 5K to a rear and just less than that on the front. The D606 is the only tire that I have used where I find that I wear the front out before the rear. I think that the wear to the front is mostly from braking with the big (320mm) rotor. As the D606 front wears I find the noise objectionable when riding straight, crank in just a bit of lean and they quiet down. Even with good earplugs and a full face Shoei the whine gets to me after 50 or so miles! I don't see this issue with TKC80s, one of the reasons I prefer them to the D606s. Running TKC80s I get about 5K to a rear and 8K or so to a front. I find the D606 to be just marginally better than the TKC80s offroad but much inferior to the TKC80s on road so the TKC80 is a better DUAL sport tire IMHO. _____ From: DSN_KLR650@yahoogro ups.com [mailto:DSN_KLR650@yahoogro ups.com] On Behalf Of Don S Sent: Saturday, October 14, 2006 6:32 AM To: Ronald Criswell; Jim Cc: DSN_KLR650@yahoogro ups.com Subject: Re: [DSN_KLR650] Re: Death Valley on Gripsters With regard to your comment that all knobbies wear quickly on pavement. I have a K270 with over 3000 miles on it and the small indentation squares on the surface of the knobs are still visible. Compared to the stock Dunlop, the K270 is super durable. I would guess that the K270 will be good for 10 to 15k miles. I ride 50/50 pavement/gravel. The stock Dunlop was finished at 3000 miles. How well did the D606 hold up?

Currently I am running the IRC GP1's and like them as well. Probably not a good idea to lean any of these over hard on the street though. I had a buddy fall on his ass doing that right in front of mr with the kendas (which have a reputation of doing that). Broken ribs ..... emmm .....bad. All knobbies wear quick on pavement however.

Uhm, guys. Once again, for 50 weeks of the year, the closest my KLR sees to dirt is what the politicians sling at each other on the airwaves. I live in the middle of a major metropolitan area of over 5,000,000 people where the nearest thing that even *looks* like gravel, sand, or mud is over 2 hours ride away, and where any "real" KLR riding is over 5 hours ride away. The question was whether I should buy a tire to be used for those two weeks when my KLR is *NOT* in urban warfare mode, not whether I should outfit my KLR with tires that are utterly unsuited to urban warfare. I have 5,000,000 crazed cell-phone-gibbering makeup-smearing maniacs trying to kill me each and every day. I don't need to worry about whether my tire is going to slip out just as I dodge around the mommy screaming at her kids in two lanes (hers and mine) in a Ford Excursion while braking to miss a Mexican in a rusted-out Crown Victoria who just ran the red lights because his brakes are shot and then jump the curb and hit the sidewalk because a frat girl in a Toyota was making out with her girl friend and wandered into a one- way street going the wrong way. That's my daily commute. That's why I'm *NOT* going to ride TKC-80's on my daily commute. As for why I ride a KLR in urban warfare, it'll jump that curb where a sport bike would destroy its belly pan, and if I drop it in the pool of oil that fell out from beneath that Mexican beater at the stop light, I just pick it up where that sport bike would be leaving crunchy pieces of plastic and a broken footpeg behind, and then when the road turns into foot-wide potholes the long suspension just eats them up where a sportbike would need a trip to the sportbike hospital. But anyhow, I need all the street traction I can get to survive. So lets quit talking about how I might want to ride something other than a street-oriented tire during those 50 weeks a year, and start talking about whether I should buy some TKC-80's for that other 2 weeks a year?!

Boys, boys! Play nice! I know Death Valley - although I have never been there on 2 wheels. Using Titus Canyon as the example, I wouldn't hesitate to take a KLR through there on stock tires. I ride with guys who have Gripsters on their bikes, but I don't have experience with the tires. They tell me that they are only slightly less capable off road than the tires that come on the bike new. Ride slow, air down, you're OK. Gripsters aren't very good in mud, but there is not much mud in DV. So, how does all the above make me capable of an opinion....? The off road areas of central PA are loose coal - when it's dry, it's similar to the gravel and sand of Death Valley. There are sharp rocks in both places. I've been both places on FOUR wheels, and it feels about the same - as long as it is dry. My Gripster friends ride in PA. They don't have much trouble off road here - key words being "as long as it is dry". If I had tires that I liked, and was going to Death Valley - or Tower City PA - for only 2 weeks out of the year, I'd probably keep the same tires on the bike - especially if I was going to ride 1500 miles there and back That's my opinion and I'm sticking to it. At least, till I experience DV on a KLR, which will be soon. Mike Lititz PA Lemoore, CA

Even the knobbiest of tires do OK on pavement after a thousand miles of wear, and full street tires can do rough terrain OK at low pressures. I think you should buy whichever tire you want and go for it. Where street tires really suck off-road is when you need to climb a wall and keep the rear end in a straight line behind the front. I don't recall doing anything that steep in DV. Plenty of climbing, but I don't remember anything that street tires could not negotiate. RM

trouble if you go over the pass at Cerro Gordo, it has some midly steep switch backs. Also ther is a bypass outside of Scottys Castle by that crater(I can hardly pronounce it let alone spell it) some of us call it11 mile whoops it bypasses some of the highway going to Beatty, that I would also avoid on street tires. other than that, I would make it a point to see Titus Canyou, charcoal kilns, Rhyolite and if you get out near Lone Pine, go see the Alabama Hills. Lots of westerns filmed there. You can also ride from Badwater to the top of Mt. Whitney in a few hours. Why?? To go from the lowest point on the continent to the highest in a few hours. Make sure to have a meal at Paniment Springs. All of these places can be gotten to on a Harley, let alone a KLR with street tires. Have fun, there is a lot to see there, even though it is a desert.

Norm 45 MPG is what I get with mine also, I took a trip to Grand Canyon a few months back, speed limit was 45 to 50 mph (park speed) got 55 mpg. Sure runs better when you fatten up the main jet!! Adam 04 KLR650 04 KTM450MXC

Ubehebe? and from there back to The Racetrack? Piece o' cake with Gripsters. If you go further than that, like Hunter Mountain over to 190, it can get pretty gnarly. (Note: don't ride this section alone!) I was there when 2 KLR riders, both with stock tires, went over Hunter Mtn. One of the guys was a rookie, and he made it. (He did fall, and broke his radiator shrouds) I would say that anywhere a 4 wheeled vehicle can go (aside from rock-crawling Jeeps), a KLR could also go, on whatever tire was on it. Adam wrote:
