The use of carbon fibre or Kevlar materials is not allowed, The TT zero rules are poor with regards to safety other than all the rules regarding the electrics, is the class a free for all regarding issues such as composite parts like frame and swing arm? The 2015 TT rules say The Clerk of the Course may on the advice of the Chief Technical Officer, disqualify any vehicle, or equipment, the construction or condition of which is deemed to be unsafe or inappropriate. Should an incident happen as a result of composite failure who's going to take blame?, as I started this post I am not having a dig but just questioning what I think is a safety issue
It is true that because TT Zero is a prototype class there are different regulations in place. Apart from the usual scrutineering that every bike goes through each time it goes on circuit, the technical crew visit the TT Zero bikes in their garages and inspect them for overall safety and quality of build and I believe they assess each one on their respective merits. We have run full carbon frame and swing-arm since our first visit in 2012.
Composite construction these days, with the widespread use of FEA and materials development, should mean that a properly designed and executed composite component will be no less a safely engineered solution than any other material.
In the other classes carbon composite component construction is banned on the grounds of safety for both rider and spectators, so why should Zero class be different?

I think that is probably a question that would need to be answered by someone with a degree in composite engineering and FEA, and those in control of the technical regulations.

RE: Team Mugen to compete at TT 2015
Hello, I've had an amazing 3 year journey with some of the greatest and most genuine engineers on the planet, I'm so privalaged to ride the Mugen, it's a work of art, pity people have a go at the class etc. best thing to do if it's not your thing just go to the pub drink beer!
