Liberty 125 VS ET4

I had an ET4 and am now using a Liberty 125.I have ridden them over long distances as well as on Londons crowded roads.
Here is how they compare
Tyre size. The Lib has bigger tyres which makes the ride more confident and stable. You can ride over small potholes with more confidence and stability than with an Et4.
Height.The Lib is taller and the rider has a more commanding ride position.It is more suitable for taller built riders than the ET4 which is a few cm lower
Seat. The Lib has a smaller seat than the ET4 and with a pillion the rider will hav to move more forward and sit at the front edge of the seat. the ET4 seat is more genrous.
Aerodynamics . At higher speeds the Lib 125 seems more stable against cross winds and head wind than the ET4 This may be due to a smaller front panel and rear engine cowlings
Repair and Maintenance costs. I find they are the same for both as the engine is the same and so is the body and most of the parts .
Their design too is almost the same and they are equally difficult to open up especially when changing the rear tyre which involves unloosening the entire exhaust assembly.this bit and changing the drive belt change are the two downsides of underbone scooters compared to chain driven motorbikes which do not involve as much work.
General Feel. The ET4 is gentler and lighter to handle than the Lib 125 which feels and handles more like a guys bike.Smaller built female riders will prefer the ET4
I have yet to ride a Vespa LX 125 or a Sym 125 .I am told the LX 125 is a sturdier better built scooter.and that the SYM 125 is exceptionally fuel efficient
