Scooter tire inflation seems to be a
very personal thing, and maybe it is the same situation with motorcycle riders - but I doubt it.
Some people look at that tire sidewall - and see the big numbers that a tire can handle before it detonates, and crank up their tires well above the book: to "increase tread life", "increase gas mileage", "better cornering stability", "higher cornering speeds", "better braking response", etc., etc.
The whole
scooter-tire-PSI thing is almost as controversial as oil types & viscosity and the fuel octane thing.
For a single rider on a LIKE200i - Michelin says their Power Pure (reinforced) rear tire should be inflated to 28 psi; their (non reinforced) front tire recommendation is for 24.5 psi. These figures are very close to the LIKE200i manual.
I have learned that I do not enjoy the ride of my LIKE200i if I stray above these numbers. And I do not think the scooter bits and parts enjoy the thrashing if I make my tires harder than that - but that might just be my personal too-gentle sensitivities. I like my scooter and don't want it knocking itself apart.
As for a scooter's weight carrying capacity: I did three things when looking at a new scooter to purchase
1) I checked the price.
2) I sat the seat.
3) I got down on my knees next to all my favorite scooters on the dealer's show room carpet - using a pen & paper to figure out the manufacturer's recommended carrying capacity.
I am 6'3" and knocking @250lbs....and had no plans to take a passenger with this, my first, scooter.
.
I think a whole lot of people are riding two-up --- at well above their bikes' stated carrying capacity.
I have heard more than a few say that the manufacturer's stated figures are well below the actual capacity of the bike.... "The company is playing it safe", etc..
Every week I use my LIKE200i for solo bopping around.
I added a Forza 300 for longer trips & loved everything about it - but sold it & moved up to a Burgman 400's 400lb carrying capacity. Now I can take a passenger.
I, too, rode a Honda 90 with my young wife on the back - all over New England back roads. We had a blast with that little beauty! No clue what its carrying capacity was - I just made good use of the gear box!
