Hmmmm, not sure on this one. Mine saved all the bodywork after a 100mph off, but I've yet to check the frame and it looks like the engine is slightly off-centre (but it might just be the airbox has been shunted across). Either way they did a good job of saving everything almost else (including the forks where the bungs completely dissappeared!) so were probably a good thing in the long run.
They were R&G, a bugger to fit, and I had to drill the fairing panels.
