I found a blog that uses basic math to show how much weight has on a vehicle's performance and wanted to share this with you:

Like I said for me it's not so much about riding a 125 as it is enjoying a bike that you can throw around like a bicycle. If I could ride a 250 that weighed about the same as a currently available 125 like my K-Pipe (around 250# out the door) I'd be on it. |
Problem with 250cc's is the power output.
It'll go faster, thus it'll need better brakes to stop from higher speeds.
Better brakes means the frame needs to be sturdier.
A grom does fine at 60MPH, but I had a similar scooter, that I took to 80MPH (downhill and tailgating), and the whole frame became wobbly and unstable!
If you're interested, there are people that have successfully modified the Grom 150cc engine with a Turbo (probably an ihi rhb31 turbo, since that's the smallest commercially turbo available), and a fuel commander; which is about as fast as the tuned 180cc BBK that's for sale for it. (Round about 100MPH)
