Paging Timo or other Pan Europeanisti...

Bollocks! You'vbe just got better PR.

 

No. The 1100, at least, is unbelievably nimble. It's one reason why Plod
likes them. I've not ridden the 1300.To me, it's just not a
Pan-European, somehow.[/QUOTE]


All our new ones have just been taken off the road due to a rather
alarming high speed weave!

JP

 

A cop I spoke to, said that the weave was very dependant on the
position of the adjustable screen.
He said that they were advised not to go over
100mph........................ "yeah right!" says he.

 

There was a recall for this, and the sump.

The weave can be sorted by re-torqueing the engine mounts. It's _very_
critical I'm led to believe.
Have a google, it's in there somewhere, or have a chat to you friendly Honda
dealer.

 

We have Honda come to us! The engine mount thing has been done and
hasnt made any difference. It is possibly due to the design of the
rear light system put on for the blues etc. They are taking one for
wind tunnel testing. The screen bit doesnt make any difference either
- doesn matter what position its in.

I've had one for just over four months (for two of those it was in the
garage after a rear-ending) and it's a treat. It *is* heavy but only
if you try to pick it up, so you quickly learn to be careful parking
on a slope. Once it gets moving it is very well balanced and doesn't
feel much heavier than my SOCB550.

I get 150 miles to the fuel warning light from full and it's about 15
quid to fill it. There's a big service at 60.000 miles to check the
timing belts.

 

They often say that but I really cant see how full panniers and a
radio pack can add up to more than carrying a pillion. I`ve got a
feeling its more aerodynamics than weight.
JP

 

Yebbut, it's positioning of the weight surely.

I know when I've got too much weight in the topbox - far far less than
the weight of a pillion - she wobbles (more of a pendulum movement
than a weave) at over 120
Don't think that the weight in the panniers makes much difference,
because it is lower.

The weight is high up and behind the rear wheel spindle, maybe that's
what makes the difference?

 

This is it!

High up the weight of a top box adds two components to the stability of
the bike.
One: is the high mass of the inverted pendulum that is balancing of the
bike.
Two: is the mass near to or aft of the rear spindle. This has the effect
of making the bike return to the vertical when the front wheel is
intentionally (taking a corner) or unintentionally (tank slapper)
turning.

The frequency and/or its susceptibility is dependant on the mass
involved and the speed of the bike that causes the instability at a
particular speed.

As above it is half the problem. You only tend to get "Two"

Any weight near to or behind the rear spindle especially if it is high
will have a disproportionate effect on the bike compared to the actual
mass.

 

Blimey, Mick. Are you sober? That was *superbly* explained....

I'd agree with all of that, with one qualification: if you can
*enough* mass ahead of the rear spindle, and as low as possible, it'll
definitely cancel out to a reasonable degree.

Loading the Wing to the gunwhales (including stuff on top of the top
box) has no noticeable effect on the handling in a straight line.

Mmmm? 1:30 ish Friday................ Probably.

I do try to do my best

 

Definitely!
This is demonstrated when laden up on my FJ12 i.e., 3 Givi 45 litre
boxes.
Add a pillion and you reduce[1] the effect of the boxes aft of the rear
spindle.

You can get tank slappers de-accelerating at about 40mph, but this can
be cancelled out by leaning forwards over the front with Jane leaning
over the top of me.

You are then shifting mass forward away from the boxes which are the
source of the problem plus compressing the front end which alters the
harmonics of the 'wobble'.

Erm? How can I put this?

The mass on the top box is probably small in relation to the bike and
rider forward of the rear spindle

 

What a diplomat.

The radio pack sits in a hump *directly* over the rear seat which isnt
behind the rear spindle. And weighing the new airwave kit and
fibreglass hump it comes in at only 2.4kg more than the standard seat
it replaces.
