Well, worthless in completely saving the valve covers, but they may have kept things intact enough to allow you to ride the bike home. I was asking since I bought the cheap plastice guards with my bike and have since taken them off. It seems like it's another step for valve adjustments that happens more often than going down (knocking on wood....) There have been discussions here in the past about the usefulness of them and I was wondering how you felt.

it's THREE bolts???? :roll:

I think that the BMW plastic head guards are good for a minor drop and that's about it. They're flimsy plastic and they cost $99 US. :x

I think that the aluminum Stanton head guards will provide much greater protection. The head covers themselves aren't too expensive, but if they were holed through, I doubt that I could have ridden home.

I bought my Rock with Wunderlich crash bars fitted, I think they will provide pretty good protection :wink:

They also provide a place for spots, which I have to say are great :D

But the crashbars look uglier than sin on the Rockster. I would have it on a GS, but not on a Rockster.

Judging by the 1" chicken strips on the sides of the front tire; the place in the turn where the bike went down; and, the trajectory of the gouge mark in the asphalt, I'd be careful saying I ran out of motorcycle. You should have been much farther right at that part of the turn and on the power. When the suspension slams to hard metal in the entrance to a turn it is usually because the suspension is compressed under braking force while you are trying to turn the bike. There should have been two tire marks with a scratch in the pavement between them. From the direction of the scratches on the valve cover and the direction of bend in the handlebar endweight (front to rear direction of grind instead of bottom to top) it looks like you simply lost the front end trying to slow down and turn at the same time. - Lee

Very easy to make judgements based on a few photo's that don't show the entire scene - I'd want to have been there and seen the incident before proclaiming what happened. :)

There is ample evidence in the pictures. The front tire shows no use of the cornering edge of the tire (neither does the rear). But in the first picture at the 9-o'clock position you can see a traction smear straight to the edge of the sidewall where there is a full traction smear indicating that it went almost instantly from pretty straight up to flat on its side. I've been riding 39 years and have seen a ton of single vehicle mishaps on the street and the track. - Lee

You may be right but that pic was taken after the bike was dragged from the bushes.

I looked at the tires afterward but I couldn't really tell because the bike hit the dirt berm going in and dragged through it going out so there were dirt and loam on the tires.

I do know that I didn't hit the brakes. I was rolling off the throttle a hair before tipping in to use engine braking to put power to the ground.

Had I gone wider and deeper into the apex, I may have clearance to scrape by. Maybe if I have had sport tires instead of sport touring, that might help. But the point of it is that the bike was pushed too hard by me and didn't have anything left to compensate for my errors.

Yes it was, but the edge scuff was still there as was the scuff line between the worn part of the tire and the edge scuff. It was not under maximum cornering traction when it fell over. This discussion has probably gone as far as it should go. I won't have any more comments on the topic. I don't mean to discredit FNFALMAN or his riding technique and another poster is correct that I was not there. I have dropped a few in my 39 years. I've run out of brain, I've run out of nerve, and I've run out of skill, but I've never run out of motorcycle. In every case there was an input change that I could have made that would have changed the outcome. One technique that is very hard to come to terms with is that when you are overcommitted in a turn, the best response is often the application of throttle. If you are too fast and trying to turn and slow the bike at the same time you will use up front traction and ground clearance in a hurry. The application of power (not engine braking, but power) will raise the suspension which adds ground clearance. It also unloads the front tire which is probably near or at its traction limit and pushing the bike wide. It adds load to the rear tire which is probably underloaded, and if you happen to slip the rear tire with acceleration it will point the bike further into the turn. Conversely, sliding the front tire widens your turn track. The keys to maintaining control are to unload the front so it has traction available to steer and to increase ground clearance so there is more lean angle available without grounding out hard parts. Sometimes you just ain't gonna save it, but when a bike crashes anyway under these conditions of maximum possible force applied in an attempt to turn the bike, the damage tracks are observably different from one that has simply lost the front end. I've seen skilled racers simply lose the front end. It don't make them feel good but they know what they did wrong. They didn't run out of motorcycle. The key to learning what to do different next time is to fully understand how it all went bad. Engine braking won't put power on the ground, sport tires won't increase cornering clearance, and a sportier bike will probably just fly off the road at a higher speed.

I'm glad FNFALMAN wasn't hurt and his bike came out ok. It's a chance to go to college on the accident. Blaming your golf clubs doesn't improve your game. - Lee

Lee,

I'm with you. I knew what I did wrong. On a more performance oriented bike like my Tuono, there's a bit more room to compensate for rider's error. This is no excuse to go out and get a higher performance bike to compensate for your errors, mind you. But I was saying that I probably pushed the Rockster to its limits that day or damn close to it.

I could have hung off more. Actually I can't hang off on the Rockster. I don't have the leg length to shag over. I can't even shift half a butt. The only think that I can do on the Rock in order to change the center of gravity is to stick a knee out and I did that.

I definitely shouldn't have hit that corner at the same speed that I would do on the Tuono. But I was in the groove that day and rode really well and got overconfident.

Shalom. I may be the next one to throw it down the road. BTW, I am with you on the FN FAL, well actually SA-58...

Just to lighten this slightly; I live near the Yorkshire Dales and Moors. The roads require a completely different riding technique because one has to expect that around every bend, there is a farm/field entrance with 100 yards of poo spread fairly evenly across the road. Er... I don't even think about grounding the stand!

Rog.

PS..... but the riding and scenery is beautiful.

I see we have censorship here. In my original mail, I used the word c-o-w-s-h-i-t and it was deleted, but in the post by fnfalman, 'shag' wasn't...

Strange....

beemerphile I think your analysis etc. is fair on the case.

What ya'll seem to have missed is the greezy bird d-r-o-p-p-i-n-g smear on the road. Or is that here on my screen... I'll smell it & get back to ya. shoo Polly!
