Exactly my point, I will design it for that speed. It is already built on an aluminum race chassis and it has dual disc brakes (hydrolic). I have a full face helmet (300 dollar one, no less. Carbon construction) and riding jacket with built in kevlar padding plus steel-tipped boots and sport race gloves. Is anybody familiar with the construction of the MBK Nitro? It's also called the Yamaha Aerox (MBK is their French division). It has nice, wide tires for extra support, awesome turning and Paoli (sp?) shocks.
Check out this link, they got theirs to do 80mph. Mine has same engine, same tires and similar rigid construction: http://www.speed-sports.com/Scooters/Dragster50_Report.html
