125cc?
Let me know when the 600 comes out.
Having said that, it looks like fule cell cars and bikes are going to be viable very soon. I recon within ten years we will see them as mass market (i.e. you will be able to get the petol, desiel or hydrogen version) and taking over within 20, as long as we can sort out the leccy issues. The sooner we build some nuke plants the better.
