Well it might simply be the tires. Check this out: http://www.dream-machines.de/technik/technik_04.html | ||

Please do translate.... Ya know, it would make sense that it might the "super lightweight" stock tires. Maybe the front deforms or something. I've thought about it a lot and thought if it was the brake as some testers have guessed, saying that the caliper was twisting some under hard braking. I would imagine it would have an adverse affect that would push in one direction, not a tendency to right the bike. So please do translate. | ||

I noticed a huge difference after changing to a different set of tires. The Metzler sportec's virtually eliminated this on my XB9R | ||

Those are the tyres I plan to go to after these 207's wear out. Probably about April... | ||

They say that the Dunlop D207 with its outdated design is causing the stand up under braking. Every other tire the tested reduced the tendency or completely eliminated it. Even the D208 is far better than the stocker. They rate the Metzeler Sportec M-1 as their test winner. Here is a jerky translation (simply run the page through Google). The translation is bad but better than nothing. If you have questions let me know I can read Deutsch. http://translate.google.com/translate?hl=en&sl=de&u=http://www.dream-machines.de /technik/technik_04.html&prev=/search%3Fq%3Dbuell%2Bxb%2Breifen%2Btest%26hl%3Den %26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8 | ||

this sunday, my front end slipped out from under me on some decent corners. M1 was behind me and saw it. I was lightly trail braking the front when it happened. Some how, it happened quickly, my foot came out and popped my ass back up. Tires? I think so! 6200 miles and the front is starting to cup.... | ||

M1, the best advice I could give anybody is to get rid of the stock tires at the earliest opportunity, don't even bother wearing them out. I kick myself for waiting but at least I didn't go with the 207 again. | ||

Actually, I don't think your foot actually touched the pavement - I wasn't any more than 15 feet behind you when it happened... I think it was one of those reflexes you may have developed while riding dirt bikes. I've done the same thing on my Honda. Well, I still have to pay the taxes on my XB12, so I'll be waiting a little while to get new tires. I think the order will be taxes, 1000Mi service, and then tires. | ||
| Wyckedflesh |
uhm...I have 208's stock not 207's.... | ||
| M1combat |
Was it used when you bought it? | ||
| Wyckedflesh |
nope...that was the way the dealer set it up... | ||

this sunday, my front end slipped out from under me on some decent corners. Tires? I think so! More like a combination of slippery surface and braking! I'd say your tyre saved your ass. If it was your tyre letting go I doubt it would have recovered you. Rocket | ||
| M1combat |
Did you hit a yellow line? I know you were close... It did just drop you a bit and then recover. | ||

"Nothing to do with brakes. Something to do with front tyre profile, rake, trail. One BWB'er mentioned that Metzeller something tyres near eliminated this effect on a XB9, as did a German mag who fitted 208's to the 12S." I like it when more and better info turns up on this board, thanks all! Now will it be "Buellstones" or 208's? HMMmmmm... Thanks XB9 it was you I was referring to, but the German Mag was a different one who did an XB12S test and only tried the 208's, after being fairly disappointed with the 207's, why are the Germans straight onto this?} | ||

my rear slipped when I hit the yellow lines. front slipped out... You know, I don't even remember anymore. Too many other near life experiences this week. She's my daily driver. 50 miles per day, during two major rush hours. Every day is a day full of women on their cell phones, driving suburban assault vehicles! | ||

LOL, Gotcha... | ||

Excellent idea lord vader... | ||

Several states here have that on the books also. | ||

When a handling malady is corrected via a new set of different brand or model tires, the effect of the different tire geometry upon the stance of the chassis is likely responsible. If the rider had adjusted the bike's sag to achieve the same change in stance, the problem would likely have gone away in similar fashion. Different brands and models tires, even though reporting to be the identical same size, often have different diameters which can significantly affect the handling of a motorcycle. Adjust your suspension sag. It ain't the tires. | ||
| Tripper |
Tire profile has nothing to do with handling? where's my geometry book? | ||
| Tripper |
It is the tires. | ||
| M1combat |
I'll set the sag, then see if it's the tires. | ||
| Sparky |
I agree with the geometry aspect. I would think that the construction of a tire can affect the handling as well. For instance a more triangular shaped cross section front tire should tend to yield a lesser tendency to stand up than a rounded profile because, in a turn, the triangular shape puts the center of the contact patch closer to the centerline of the tire thus exerting less leverage to push the bike up. This is the principle, I believe, that Metzler advertises with the construction of its Sportecs. They strategically place stiff steel belts adjacent to the centerline in order to reduce the offsetting of the contact patch when heeled over in a turn. The result is a rounded profile that acts more like a triangular shaped tire to help minimize standing up in corners (better than the stockers). | ||

I went to the Michelin Pilot Sports on my '03 XB9R and while they seem much heavier in weight (I did not weigh them), they perform so much better than the D207's or D208's IMHO. I recommend them hands down over the D207's and maybe the D208's. Kinda miss the road feel that I had with the D208's however, it NEVER felt like the back was going to go out from me in the deep twisties.... got to get the new Mich. tires hot to feel comfortable in the deep twisties and was a little different in feel, but I like 'em!

Doesn't it boggle your mind when a "technical" article blames the bike's "standing up" on having a single disc? I mean, if it turned the front end one way with brake forces, then it would stand up in one direction of corner and lean down the other direction. I am now utterly convinced that well over 50% of all magazine writers are total wonks, unable to ride or think. Some are absolute aces, but I'm not sure magazine readers know the difference, unless they have been around a long time and get to know who to trust. Like, can you believe this dickhead kid writer saying that an XB12 is the worst bike ever, like happened in Motorcyclist this month?. What a freakin' joke. Not only are well known and fast journalists from all over the world saying that these bikes handle superbly well, but damn near 100% of the owners love their bikes too. I sure love mine. I was OK with the stock tires, but I do like the Pirellis I put on better. But, hell, fine tuning handling with tires is no news! I'm willing to bet that damn near every Buell owner can out-ride that little squid from Motorcyclist. And in fact probably most readers of the magazine can as well. But they may never go try an XB after reading these lies. Shame on this little turd, and on the magazine editors at Motorcyclist as well. | ||
