riding characteristics

[GeoffBayes]

I've never owned (or ridden) a scooter. Motorcycles yes, although I sold the Honda Hornet in March. I'm thinking about buying a Burgman 400 (although it may not be this year), and I have a question about scooter riding characteristics.
As I understand it, the power transmission of a scooter consists of: engine - front pulley - drive belt - rear pulley - clutch - rear wheel, with gearing here and there. So while the engine is idling everything is spinning as far back as the clutch, only half of which is turning. Rev up and the clutch bites and the rear wheel turns.
But on the overrun, say, fifty miles per hour, on an A road, close the throttle and the clutch stays engaged because it is turning at the same rate as the rear wheel. And this is the case until the road speed drops to a low enough level to overcome the centrifugal force on the shoes.
Is this right?

I think that when I've made my mind up I ought to talk to my local dealer about a test ride.

Hi Geoff and welcome

You are correct about how a centrifugal clutch works.

Hello & Welcome Geoff.
I would not know about that....i have a TMax....its a bit different to the Suzuki drive line.

Yes mate...
The difference in spring rate of the clutch shoes, determines the point of take-up - along with the variator weights / determine the revs it all engages... as you say close the throttle and its down to the spring rate at the rear as to what road speed it starts to free wheel... can feel a little disconcertain free-wheeling at speed, bit like pulling the clutch in when doing 30! usually happens around walking / jogging pace...

Drive wise its a little like riding with clutchslip, the revs / drive is behind your input... and for cornering you slow and drive thru, rather than drive out...
Get a go on one, 250+ judging by you current bike background... they are great!

Just remember! its a rear brake and not a clutch...

The CCM Supermoto may be going soon... but i wouldnt be without a Twist n Go now. specially on a commute..

On my older Burger, the clutch disengages as I go down through 2,000 rpm.
