Hello all, I've been riding motorbikes for 35 years but only got my new PX150 a month or so ago - I'm really enjoying it but...
A couple of times I've been riding along, taking a right hander and 40/50mph and suddenly it's felt as if I've picked up a puncture, very unstable and vague steering. Obviously, I've pulled over and checked everything - tyre pressures are spot on, wheels and steering head don't seem to have any play. This has yet to happen on a left hander, roads are reasonably smooth - I can't work it out.
I don't think it's that I'm not used to the smaller wheels, I've done a couple of hundred miles and don't expect Ducati level handling but it does feel as though something's not right. In truth, it feels dangerous when it happens. In my youth I had a nasty front tyre blowout on a Guzzi when carrying some speed, I stayed on but did not enjoy it - I really don't want a repeat of that!
Any ideas would be gratefully received.

Assuming everything is mechanically fine, could it be the unbalanced weight of the motor to centerline, affecting how the scooter feels
when turning right? I know I sit more to the left of the seat when riding at speed. I'm sure others will chime in soon!

alright jedi , hows the summer in the colonys .
weird 1 rightside ,as its a new px we can assume the engine mounts arent shot ,unless you mean new to you . an reckon you arent ready to push it far enough to get a knee down an skim the selecter box on tarmac , it is possible an not a comfortable feeling . check tightness of engine bolt an mounts just in case ,if there good reckon its likely as jedi suggests .there a totally different game to motorbikes with the weight of centre ,turnin right n left will feel different to each other .
you could try only turning left for a while til more use to it ,but would make rides pretty boring .H

Haha! You're right, I'm not quite knee-down on it yet! I'll try out your suggestions (apart from only turning left Henri!) - thanks all.

was out on mine earlier an tried to replicate ya description ,i run bikes aswell so was trying to ride scoot like a bike .bit of a head squeezer but ,only thing i could find is maybe your still altering your braking or braking mid corner .get away-able with on a well set up bike ,but not so comfortable on a scoot ,especially in right handers were the off-centre weight has more effect . couldnt get a blow out feeling tho, but mines got rally "head-shaker" forks on , hard to feel a real blow out with all the other quirks going on already .

Maybe you've got a point there Henri, I definitely wasn't braking but might have not held a constant throttle position - when it stops p*shing with rain I'll test it out - thanks.

best bike analogy i can come up with is if youve ever ridden leading link forks ,same deal , pick ya speed an line ,wrestle it in ,go round like ya on rails n wrestle back upright. just god help ya if ya find a dead hedgehog or badger on the racing line?. or if ya drive triumph cars like me ,reputation for tuck under on rear wheels on cornering ,caused by suspension changes if power/accelerators lessened . simple cure ,dont bottle out halfway round ,surprised a few mg owners with that one .when ya use to vespas there very predictable an reliable ,you'll get it .anybody who got use to the "guzzi tick-over/low rev wiggle n shake" a vesp will be easy .
