Ride stability with a pillion passenger on a scooter v m/c.

[5davidhen1]

Please can anyone offer any insight to my dilemma.

 

A year or so ago I was riding an old m/c (engine size I think was 110cc) which I was able to handle quite well with my g/f on the back, even though I had not ridden a m/c for over 40 years. A few months ago I splashed out on a brand new Honda Lead 125cc scooter. I handle it quite well when I am riding solo, but with the g/f on the back, I struggle to keep balance at low speeds.

I am wondering if it has anything to do with the fact that my scooter has smaller wheels, affecting centre of gravity/dynamics.

Or, could it be that my g/f (who doesn't ride) is not the best of passengers for sitting still. But, I don't recall a problem with the m/c, which brings me back to the different sized wheels possible reason.

Maybe someone out there has had similar experiences when changing from m/c to scooter --- with, or without a passenger.

Any suggestions?

Go Faster..............

Completely normal and slightly dangerous.  Not much you can do about it other than getting a smaller version of the current GF.  It is hard for my girlfriend to not lean the opposite direction I desire and also she has nice view compared to your old ride which complicates the situation.  Before she never saw what was happening Infront and the instinct to lean was negated..

At slow speed the rotational stability through bigger wheels doesn't matter much so probably more a factor of your gf not being an experienced pillion. Maybe the seat height is higher as well which would have a negative effect on stability with pillion. The 110cc might have been a Wave.

I am always riding between check ins/outs with my business partner on the back.

No problem with stability at high or low speeds until.....    she sees a bluddy snake or 'baby crocodile' (monitor lizard).

Then -

Screams in my right ear.

Lifts up her arms in horror (lifting up my shirt as well).

Suddenly jerks her legs up meaning that her knees knock my elbows. Mr Wobbly for a few seconds.

Stability - probably 2/10

Avoid weaving through traffic at low speed, definitely more unstable with 2 at low speed

Tell the person on the back to not lean left/right.

the "wobly" feeling should subside after a while.. you will get used to it and able to control.. dont fret

IMHO

 

Honda Lead sux.

There you have it 5davidhen1....  the scientific explanation to the issue your are facing is 'sux'.. 

 

As you rightly pointed out, the issue is likely to be the smaller wheels and quite possibly a steeper rake compared to the previous model you are familiar with. 

 

Both contribute to greater manoeuvrability, the pay off is a loss of stability - as another poster mentioned, you'll get used to it.

I was riding pillion on a Bangkok moto-taxi.  We had to make a hairpin U-turn around a set of traffic cones (Set-up, of course to prevent the right turn across traffic we were about to make) He actually went too slow, completely lost headway and over we went in the middle of the turn.  Naturally, a city bus was barreling right towards my suddenly prone body.  Got to say, for a 75 year old, I moved pretty quickly, rolling to the curb while getting a unique view of the underside of the bus.  Too slow can be a problem, especially 2-up.

Perhaps the new bike is much lighter at the front.

In my 1960's mod days, the scooters of the era, Vespa and Lambretta had 10-inch wheels, but you could throw these things about no problem. 

 

But, the difference between the two, 2 up was, the Vespa was very light at the front and needed way more care, whereas the Lambretta was better with a passenger, all down to design differences and weight distribution. 

 

I didn't like the Honda click, a bit like a Vespa, the Honda Airblade/PCX were way better.

Definetely.

Has she put on weight since a year ago?

Honda Lead is too small, on my old model Forza, which is usually mocked here... ????, it's very convenient to carry a passenger, it's a heavy and long wheelbase scooter with low center of gravity, it is very stable to ride alone on long road trips at 100kph or even higher, and I have had 65kg passenger (large chica I know ????) without even noticing I was carrying someone..., very smooth and stable . 

 

On long trips with a lot of luggage and top box, it's also very stable, my advice is to upgrade to a Forza or Xmax if doing a lot of two up and heavy luggage trips - then upgrade the rear shocks, then will be in heaven...(well, if she's hot... ????).

Just put her in front of you (preferably w/o panties) and ride cowboy ride. (scooters are more stable with the load between your legs)

Check your tire pressure. I find that it's far more critical for slow-speed riding with 2up than just me alone.
