Sure looks like you can sit way back on that forza. How's your feet riding position? Is it up close and personal to the leg shield?
The riding position is fine for my 6'3" legs.....the seat I thought was going to be an issue for comfort - but I can ride for hours with no issues.
As it sat on the showrrom floor of the dealer, I sat it several times....and noted that the freely naked handlbars would be as easy as a bicycle to raise to get the brake levers away from my knees under all turning conditions. That was completed 1/2hr after I got it into my garage.
As a big guy - I do not ride a scooter with my knees straight ahead like a little Vietnamese or Italian woman - but I can do that if I need to and do not have any problem with room for my knees.
As all you 300+ owners know - these heavier scoots ride like a Buick, and are almost as comfy.
