its happened twice now if I grab too much front brake the forks snap violently all the way to the right! I'm thinking its because of the six piston caliper only on the right side. Has this happened to anyone else? | ||

>>>>I'm thinking its because of the six piston caliper only on the right side. If that has happened . . . .you have just rewritten the laws of physics . . . . or have a rubber axle. The ONLY way that the brake on the right side could induce ANY (I meet the slights) deviation from a straight line . . would require about 7 other pieces to move. The FBD for this has been previously posted. Interesting. | ||

if I grab too much front brake That should tell you something surely? | ||

Never happened to me in 12 years. You got issues - or like Court said - you are challenging the laws of physics. Kilroy | ||

are you braking into a right hand turn? | ||

Clean your PADS and ROTOR !!! CHANGE your brake fluid once a year !!! TORQUE the front axle to SPECIFICATIONS !!! BE VERY CAREFUL WITH APPLYING THE FRONT BRAKE AT ANY TIME, AS IT WILL PUT YOU ON YOUR "ARSE" !!! (Message edited by buellistic on February 23, 2012) | ||

Single disk front brakes have been available from various manufacturers on many different models for 40+ yrs; at least since the '69 CB750. Your situation is not a function of the design. Were it me, I would start at the front of the engine, and confirm the health and security of the front motor mount, the tie bars, the isolators, ect. Try pushing the rear wheel from side to side to look for play at the swingarm attach. Then I would check the steering stem bearings and work my way forward and down. Triple trees, bolts, forks, axles, wheel bearings, ect. If not caused by an unseen/unnoticed road hazard (rock, sand, ect. Could be possible ...) you have something else going on. Hope this helps, Dave | ||

With 95K miles on my S1 I suggest you start with Akbuell's plan first. | ||

Way to go AkBUELL ... Thats good "INFO" on "HOW TO" !!! | ||
| Buellsrfun |
thanks akbuell had to think for a min. I road a 1973 cb750 for many tears with no problems was a great bike wish i still had it! now i can see that i need to start looking at the whole bike unfortunately i ride better than i wrench and so far no shop has ever said anything other than the bike is fine. I do go through a lot of shops because they ether know about sport bikes or harleys. and they they all seem to have judgement about the buell, thinking its really neither one. | ||

>>> the forks snap violently all the way to the right! Yet here you are typing on a computer keyboard and not in a trauma ward somewhere. Troll. | ||

Blake: Why didn't you suggest wider handlebars ??? (Message edited by buellistic on February 24, 2012) | ||

Yeah this is quite bogus, never had the issue happen to me, and never heard about it happening to anyone else on here. Just because there is a 6piston on one side doesnt mean it'll snap the wheel to the right.....that'd mean the later calipers (XB/1125) with EIGHT piston calipers would mean I've already been off of a mountain more time than I can count since it has two more pistons on only one side. Come on, dont even try to blame the design on your bike behaving poorly | ||

Is your hand wrapped around the grip when the bike snaps violently to the right or are you just hanging onto the brake lever and yanking on it when you want to stop?  | ||

I had it happen on my Uly right after I got it. I knew something was wrong and started digging. First started by making sure the fork legs were parallel. Loosened the lower pich bolts and bounce the front end a few times. No change at all. Closer inspection found a slightly bent left fork tube. The PO had dropped the bike and this was left over damage. When you hit the brake and the forks compressed the slight change in the plane of travel of the left tube made the bike pull to one side. New fork tube and problem was gone. Brad | ||

My bad for not asking sooner- Did the situations you described happen at very low speeds with the forks turned, like when turning around in a parking lot?? If so, then there is probably nothing wrong with your bike, and you have answered your own question. Too much front brake applied WAY too quickly. Otherwise ...... | ||

the first time it happened was on freeway splitting lanes doing about 40mph when a car turned in front of me and I hit the brake and the forks crossed up and I was hopping/skidding the front end straight down the freeway pulled it back around was fine! the second time at about 55mph in a slight right hand bank and a truck with no brake lights slowed way down and I'm way to close grabbed the brake next thing I know I'm sliding on pavement. that was back in july I'm still disabled post opp from a grade 4 shoulder separation. buell survived with min. damage replaced intake wrap scratched pipes and repaint and its better than before! also I did buy it as A project it went down on the right side loading it on a truck so the guy said and had been sitting out side covered for about a year or two and didn't run. So it was A wreck and now I suspect fork damage. | ||

Neither of those situations sound like the brake snapped the forks to one side. It sounds like you LOCKED the front wheel (which was already turned to one side) both times, which magnified the "turn", and it started sliding. Two fingers, grasshopper. All I've ever needed, even 2-up on a racetrack. | ||

OK, for your first incident, be aware that most California freeways have Botts dots on the painted lines between lanes. So if one is splitting lanes and happens to hit the front brake while running over these damn things, it's entirely possible for the front wheel to momentarily lose traction and do something wonky to upset handling. At times it's caused me to deviate slightly from my intended line while running over them, I'll give you that, but never did it snap the bars violently. So there would also have to be something seriously wrong with the forks like really worn bushings that might cause a lot of unintended fork flex, or worn steering stem bearings having an adverse affect on steering. You should have someone trustworthy check out the suspension and running gear to make sure it's 100% OK. Or it's pilot error and the OP ... | ||

If your fork leg is bent it could cause twisting of the triple trees under braking. The brake affects the hub of the wheel, which cannot cause twisting. If only one side of the forks is free to slide, then you might get handling anomalies. Change your fork seals and roll the fork tubes on a checking plate before re-installation. | ||

Semantics shemantics. The front end washed out and he crashed. Just because he uses the wrong words to describe it he gets called a troll... At least some of you manage to intelligently discuss the possible causes and solution without resorting to pettiness. Grade 4 separation, that is severe. I had the same off my bike and had surgery also. It took a good 2 years to get back to being able to ride any distance without pain and about 4 years before most all soreness went away, so hang in there. | ||

You probably know this already but applying front brake when the bar is turned in any direction, even so slightly will pull you down to the ground. That's the second golden rule of motorcycling I learned when I started riding. Not sure if this is your issue though. | ||

A broken front mount bolt can cause some unusual steering conditions. I have sheared the left bolt a few times until I found the best vendor. The right bolt never broke it broke the head. A torn/broken upper isolator can cause some unusual steering conditions. |
