Hanging off

[Centaur]

Why do peeps hang off the bike in corners. Lower the centre of gravity of the combination of bike and rider??? Any other reasons??? Read somewhere it allows the bike to take a given corner with less lean...if so how? I'd love the occasional serious answer. man8um

Was that a serious question then or are you just fishing?

I concur, Bill.

Bill...

The instructor Shaun at the RSID went into this in depth. It was all to do with CoG points and the like. I can't remember all the details either but it went along the lines of a bike will corner better (faster?) when the rider is hanging off. I seem to remember him saying that a bike with a rider hanging off can be at a lesser angle than a rider being perpendicular to the centre line of the frame, and still corner easier with less stresses on tyres etc.

He drew diagrams explaining, lines thru the body and the wheels centres etc??

Need to eat more fish Bill?? (joke, btw!!)

As above but I just do cos it looks :-: and I like my knee sliders well worn
seriously though it does make a difference and in the wet keeping the bike more upright has gotta be a bonus makes a lot of sense for me anyway

also,you've got less distance to fall to the road when you have an "off" :dunno:

I was excused the briefing due to my age Stan!!! man8um Blu, "HOW" does hanging off allow the bike to go round a given radius more upright???

i think(not usual for me i know)it's because you are lowering the CoG,in as much as it's like the difference between a sports car going around a bend likened to a double decker bus doing the same speed around the same bend :dunno:

probably wrong though..as usual :blush:

 

[Centaur]

I don't think so Stan

I know it works otherwise t'guys wouldn't do it but can't see how lower c of g allows bike to lean less for given radius. BTW have you seen the films which show how far a dd bus can lean over and come back....amazing! really hoping for someone who knows the physics of how a bike corners to give us an explanation....no offence meant :k

none taken bill....i sort of know how it works,but i ain't doing a particularly good job in explaining it am i c7u8 .the lower an object is...the less gravitational force is put upon it.as for the physics of it..i'm fooked,but does it matter....so long as it works :k

I've rarely leant off the bike as I've not really found I needed to on the road.

I do believe that there's actually a trade-off to be had between lowering the C-og-G and maintaining good control.

I actually saw someone a couple of years ago coming the other way on the twisties into Machyll....watsit in wales heading into the corner with a traily bike almost upright but hanging off the bike. Just after he went past me I heard a very loud bang....... he ended up hitting the front of an oncoming car with a family (with two little kids) and being flung over the armco and into the trees.

IMHO is proly only worth hanging off when you've reached the point where you're grounding all else, are still in control and want to maintain you're speed.

Knee down has never really been my riding style... but then maybe I'm just an old slowcoach who knows no better.

I've no doubt it can help you get round corners quicker but on the road it's usually wise to leave a little bit of margin for the unexpected...

I will of course ceed defference to the more experienced knee downers out there :bow:


ianrobbo....... were you knee down when you grounded you're fairing??

 

[ianrobbo1]

Nope!! didnt even try!! :t no sliders!! :} hung off a "little" bit though!! cos Bert said I should!! :wank:

You never see a copper hanging off his patrol bike and the ones I have been out with on the road are never far behind no matter how hard I try. So is it down to leaning off the bike in a high speed corner or is it correct positioning, timing and good use of gears/accelleration ?

I know which looks more controlled

My 5 cents worth......

Having completed 2 levels of the Cali Bike School, I can tell you what we were told by the instructors...

Leaning off the bike achieves 2 major things:

1. Lowering the CoG (and shifting it further) into the corner gives the bike better lateral stability

2. Because of point 1 above, you do not have to physically 'pull' (or lean) the bike lower into the corner and thus have more tread on the road as you make the corner. More rubber down in the corner means you can carry more speed around the corner.

Scraping your knee on the tarmac is a by-product of leaning off the bike... I have heard it said that Rossi etc use their knee as a guage to 'feel' how low their bike is to the ground...

I was just gonna say that
D&D the guy who hit the car prolly had nuffin to do with hanging off more likely down to the twats road positioning
done correctly it works as for is it necessary for the road prolly not but it does depend if you use the road as a race track or not
I go out with a guy who's an advanced observer and trains guys to become observers
when we're on our 1150gs's and he's in front both doing the same speed and taking the same line his angle of lean is much more than mine as he don't hang off
never had the need to hang off says he
but then he says we were pushing the limits on that one weren't we
I'm thinking nah mate I could have gone round there another 10mph faster and still felt confident
another advantage is if a corner tightens up on you the last thing you want to be doing is counter steer the bike with it lent over but by moving your upper body more into the corner will tighten your line without the need for another steering input
I've only been h/o for 3-4 yrs and don't do it all the time but it's a good tool to have in yr box

Of course this wouldnt be more than 60mph tho would it or you would be breaking the law man8um

 

[stan the man]

cos if you highside you have further to go and the moment of inertia would multiply making it worse.

mac.....your right of course...."BUT",my statement was a little pisstake on blu's behalf.....going fishing,so to speak :k
