Funny how people are suggesting you to buy a new motorcycle!
You don't throw a brand new suit if its button is broken. You just replace the darn button! Or at least that's what common sense suggests.

Anyhow, here are my few suggestions:
1. Shave some foam from the seat.
2. Cut the suspension spring.
3. Cut and lower the length of the "rod" below the suspension (Don't know what it's actually called!) then just weld it together. Not recommended!
4. Wear shoes with thick sole.
Use option no. 1 with no. 4 together and I'm sure it'll work. If not, then just cut the springs, simple!
Disassemble the two shocks, take out the suspension springs, cut one or two windings of the suspension with a hacksaw, do the same with the other one, put it all together and voila! Or just take the bike to a 'suspension ustad'. I'm sure he'll know what to do.
Hope it helps.
