Actually I asked if it I should worry about it bottoming out on SPEED BUMPS. I never said anything about potholes or anything else for that matter. I have yet to go over a SPEED BUMP so i do not know. Im not "claiming" anything, it has not bottomed out on anything, thats a fact. Also those numbers in the Service manual do not say anything about Carrying capacity thier just random numbers, i have yet to figure out what they mean. Also, a weight for one person being 120lbs? and 2 at 240lbs?..... I dunno about that that sounds like a bit of a stretch. The scooter seems to handle my weight just fine. I was curious as to the max weight because ive seen smaller scoots (honda sh 150) that hold in excess of 360lbs.
You should define a speed bump. We have at least 5-6 types in my country. If you are talking about thin rubber "vibration type" stripes that are approx 1/2 inch high and few inches wide, you can go flat out over them and scoot will not even feel them even fully (over)loaded. There are also wider oval speed bumps/stripes that are typically painted in black-yellow, approx 10 inches wide and 1.5-2" high. I would advise slowing down significantly because it WILL bottom out. Then, there are variations of the first two, and also speed bumps made of raised asphalt that have incline/2 meters of flat surface, sometimes with pedestrian crossing/decline.
You do not have to figure out anything as carrying capacity is 2x55 kg. I have first mentioned 2x54 kg because Kawasaki declares its bikes at 2x54 kg. I had it in the past, so that's where this number comes from.
Carrying capacity of my gf's 50 cc Piaggio is higher than P250's. A125's declared is the same as P250S's, but it does not bottom out and P250S does. Etc.
Well, just took my baby for its longest ride yet, decided to see what would happen so i went over a speed bump and off of a rounded curb. Neither caused me to bottom out so looks like were golden. Thing had OUTSTANDING break as well. I was coming around a corner going about 35mph and the cars in front of me had all stopped right at the exit of the corner. I straightened up and stopped no problem right out of acceleration. Looks like my little darlin is handling this big guy just fine!
It is difficult to comment riding styles, but it is important that you are satisfied.
Two more things:
1. Locks front wheel VERY EASILY and despite dual front brakes tends to slide the wheel to one side when approaching locked state. VERY VERY dangerous.
2. When cornering heavily it tends to dangerously WIDEN the trajectory, especially two up. To give you more information, I am currently around 250 lbs. It does so the most of all scoots I ever drove. So, I do not recommend to anybody to push heavily P250S through corners when fully loaded.
Then again, I do not consider myself to be average scoot driver because I ride mostly scoots for the past 13 years, 365/24 and my usage pattern might be slightly different than usage pattern of most people...
