Also remember that this is a cheap single cylinder scooter and not a fine expensive BMW.

Ooohhh Man, that hurts. :lol:

Mr Jones is obviously not aware of BMW's very poor reliability record, particularly in recent years.
I wouldn't trust one to last 65000km like his parking-lot-wrecked Forza did.

The Forza, like any other mechanical compromise, has its own limitations, but to call it
'cheap' as compared to RUINOUS competition is simply ridiculous.

Hope life stops beeing miserable, innit!

My glorious Honda Forza 300 took me through the Fraser Canyon this afternoon without a single breakdown. I had to battle random rocks on the road from the mountains. I gave way to people who wanted to travel much faster than me. I spent very little money on gas and a larger amount on pepperoni, ice-cream & coffee. Not one drop of rain fell on me but I did fear a yellow cloud fast approaching from the cold north.

No it doesn’t.

Its important to understand how the clutch works.
It has friction shoes which are thrown out by centrifugal force to take up the drive.
Once the shoes are thrown out and the clutch is engaged the clutch stays engaged irrespective of RPM until the speed drops to the value at which there is insufficient centrifugal force to hold the shoes in place.
As far as I recall the Forza clutch drop-out speed is about 10mph.
What this means is that controlling the speed with the clutch at walking pace as you would with a manual clutch motorcycle is pretty much impossible.
Go below 10mph and you're freewheeling, in order to increase speed from below 10mph you need to gently open the throttle and let the clutch do its thing.
If the clutch/throttle gives you a bigger increase in speed than you want, the only way to control it is with the brake, preferably the rear one because your right hand will still be modulating the throttle.
Its not difficult to do, just different.

Any judder is due to a fault, most likely glazed clutch shoes, a cure is to do a series of full throttle starts.
The more mechanically sympathetic way is to disassemble the clutch (p.i.t.a. of a job) and lightly rub the shoes with abrasive paper.

The lighter you are on the throttle when moving off the more likely the shoes are to glaze up.

Thanks for this info, my PCX is my first CVT bike after lots of MCs. I find myself accelerating more reasonably now, so I'll keep this in mind. For some reason, I ride more responsibly on the PCX, and I enjoy riding just as much.

gn2 explained it better than I can. I just said ride it harder. Quit being so gentle.

Nah, I think I'll continue to ride it reasonably, and if it seems glazing has occurred, then I'll hammer it a bit. I learned years ago that street racing is for wanna-bes and If I wanna go fast I'd be doing this .....

A series of full throttle starts will cure a juddering clutch only sometimes, and then only for a while.
More like, telling yo-yo he's a cret*n ...comes back after a while with a vengeance hahaha.

Take it apart and clean it, takes an hour or so, and there are good chances the cure will last.

With the centrifugal clutch working fine, low speed smoothness depends on the rider's ability with
throttle/brakes, something most drivers come to manage quite naturally, not having a clue of
the mechanicals or physics involved (which are even more complicated than presented here above).
Suffice to say that CVTs are simply built, simple to service, even if amazingly complex in operation -with about a dozen parameters interacting, not just engine rpm and drop out speed, so I WONT
get into that...

Sir...s--
I also have a 2016 Forza with approximately same distance on the odometer and I have no such issues. So there is certainly an issue here with the pilot's Forza. Myself if confronted with this challenge I would first check to see if the throttle is properly adjusted within specs which if it is not would NOT be a warranty issue. Almost seems as if the throttle is sticking?

Better yet, as posted by BPT7594, non PCX clutch pads (22535-KVB-900) resolve the clutch chatter issue. Some have also installed them and noticed a much more satin- like smooth takeoff.
