10 years ago I crashed my Super Blackbird. It took me a while to work out why (I thought at first that something had gone wrong with the front brake) but I eventually worked out that, partly due to adjusting out any play in the throttle) I'd leant on the bars under hard braking and partly opened the gas, resulting in me pushing a locked front wheel into the bend and the inevitable result.

Since then I know I've done a similar thing twice, but on both occasions I fortunately realised very quickly that the engine was labouring under braking and closed the throttle damn quick with no harm done. However, several times now I've been speaking with other bikers, some of whom are the most experienced and best riders I know, and they have also reported making this error at least once.

So, for reasons I'll explain a little later, I'm really curious to know if anyone else has experienced this. I don't necessarily mean that has resulted in a crash, I'd just be keen to know if you have ever realised that you had the throttle partly open under braking... so here's a poll :)

Thanks for any contributions... :beer-toast1:

I know what you mean .

I use all 4 fingers to brake with which makes partially holding the throttle open quite difficult .

When your braking using 1 or 2 fingers your thumb tends to loop around the throttle grip

I have done it myself though yes

I have done it but noticed, One defensive strategy I have is to use the clutch to softly disengage drive rather than the sudden cut off caused by closing the throttle.

Not that I can recall. Of course, some do it deliberately, but they have names such as Rossi, Lorenzo, etc.:)

Why would one adjust the throttle freeplay to the point where it can be working against you? Operator error? Other than that, with modern ABS systems that can & do also interact with the throttle setting the risk of such a thing occuring is further mitigated. Isn't technology brilliant. :)

SIOM.

Been there and dunnit. I think Mick is right about how may fingers you use to brake with. Why didn't you put that in the "yer best riding tips":)
Mick, do you cover your brakes with your fingers when riding or only when braking?

Yes occasionally, didn't we discuss this on the French Tour Keith, or did I dream that bit??:dunno: It can be down to how the throttle tube is positioned on the bar and in many cases this cannot be altered :(.

Personally, I don't like a lot of free play on the throttle, I adjust it to the minimum of free play, just make sure when you go from lock to lock the revs don't rise, then that's perfect for me. :) Just like the front and rear brake, I don't want a lot of free play, I prefer the minimum of travel, and a firm feel. :) Ok keep it nice, regards feel. :d: :)

I never cover the brake , I have tigger happy hands :}

I used to cover it when filtering but as above , you really really don't want to be grabbing a handful when there is a car inches either side of you .

It only take a nano second to get the fingers on the trigger as it were .

I think it's a physiological thing , your head is telling you to cover it , be Cautious , ride defensively n all that bollocks

But the temptation to give it a squeeze at the slightest unfamiliar movement ahead is just too tempting

So I keep both hands wrapped around the bars

Same applies with my clutch hand

If they're both covered there is a tendency to squeeze both together and if you want to slow down quickly it sort of defeated the object

Usually cover both levers whilst riding and consequently have had throttle on during braking a few times. Never had any dramas from it but not proud of myself. Still learning.

On Yorkshire weekend, downhill right hander over a bridge. I was sat up, slipped forward in seat not gripping tank with knees, loaded up the front with straight arms pushing back and my thumb rolled down the throttle a fraction and I shot towards the outside of the apex. It was closer than I'd have liked! Gibber gibber!

I've not done it in the scenario that you've mentioned Keith, well certainly not that I'd noticed consciously or remembered. So I'm an (almost) a never in your poll.

Like many, the only time I brake and accelerate is a lower speeds for manuv...manouv.. turning the bike, when you play the rear brake off against the throttle to give extra control. I'm certainly no Marquez. :bow:

Thinking about it, Mick might be onto something, I'm not a sports bike rider and consequently am a four finger braker too. Might this be a clue?

Also, without intentionally being personal, might rider weight be a factor?

Interested to hear your theory.

:beer:

I think this is an urban myth. I have never read anything on motorcycle braking techniques to suggest that any of the top racers use throttle and brake at the same time, nor can I think of any logical reason why they would. Either you want to be slowing down, or speeding up, applying both together achieves nothing other than to increase wear on the brakes, tyres and engine; none of which are desirable. I'm very happy to be proved wrong if anyone can find a reference, but if there isn't one anywhere on Google, it's almost certainly a myth.

I should add that I've only heard of this happening accidentally when really going for it, never in normal or even spirited riding. It's when braking really hard so you have a lot of extra weight on the bars.

No Phil, you didn't dream it, you were one of the people who have said that it's had happened to you. Specifically, when you were chasing me up the Route Napoleon at speeds very few riders would normally do :eek: (I keep saying I won't do that anymore, you're such a bad influence :).

Anyway, the point is that now so many bikes are "fly-by-wire", I think there could be potential for a useful safety device, one which does a soft close on the throttle if you're braking and have the clutch out (engaged). Such a device would have saved me a crash and so I was wondering how many other riders might have experienced the problem. Anyway, Honda don't offer anything for ideas :rolleyes: so I submitted it to BMW who say on their website that they pay for good ideas :) , time will tell!

Thanks for all the replies. :beer-toast1:

Rear brake. A primitive means of keeping the front end down? I dunno.:dunno:

Front brake, I agree. I can't think why anyone might want to do it. Come to that, I find it difficult to fathom how someone might do it inadvertently, but it obviously happens. Maybe I'll give it a go?:d:

rossi =

3 on the brake
2 on the clutch














Doesn't really give a diffinetive answer

It's just 2 random photos

So maybe it depends on how much force he wants to generate as to how many fingers he uses :dunno:

So the question is now, after submitting this idea to BMW just over 3 years ago - do I sue! :mad:
