sidecar directional stability

[f14rio]

i know that as speed increases drag increases exponentially. so the parasitic drag caused by the sidecar quadruples as speed doubles which causes the rig to pull to the right .

my rig is okay up to about 50 mph but steering corrections for adverse yaw are a bit uncomfortable at 70 mph.

do i just live with this or can i trim the suspension for higher speeds?

or, would additional weight be a possible solution?
thx.

Sidecar Stability at Speed

You may have problems with your sidecar setup. Neither of my two sidecar rigs has ever acted like that. The first was an Earles fork frame with a 1978 R100 engine and a Globe sidecar - rather light for the bike. My present rig is a K100LT with a Hannigan sidecar. Both rigs are/were quite stable at the highest speeds I could reach. I would check my alignment, toe-in, etc.

I agree with Whitlock. I ride a '99 R1100 w/EZS Summit car (about 235 lbs) and I have very neutral steering at almost any speed I ride. Check the set up, there's got to be something not quite right.

I had both my kid & my wife in the sidecar last weekend. The rig pulled to the right a bit, but I used the electronic camber control to raise up the outboard side of the sidecar little by little til the handling got more neutral. Once I got it dialled in, no problems & straight & true tracking even up to about 75 mph.

Having said all that, without the ECC I don't know what I'd have done except rub my sore right wrist when I got home

"sidecar directional stability" is an oxymoron

Somewhat like the definition of a helicopter.

A loose assemblage of parts, flying in relatively tight formation, all bent on self destruction and becoming random in motion.

Helicopters can't really fly - they're just so ugly that the earth immediately repels them.

Why do you think there is gravity?
It's because the Earth Sucks.
