You've already taken precautions and fitted one of our inexpensive racing fairings, and despite the fact that the last crash cost you money. What helps you against this are stable crash pads!
There are crash pads for all critical crash areas. These are firmly bolted to the frame or motorbike and absorb the forces while the rest is spared. Replacing a crash pad is much cheaper than having to replace a water pump, brake caliper or fairing, for example.
Crash pads are like airbags in a car. You don't usually think much about them but when you realise you need them it's too late. So think about it before you go to the track and fit the crash pads you need!
If you know that a possible crash won't be that expensive, you'll dare to try out even more lean angle and speed more easily and thus get better times.
Of course, the crash pads also help to minimise damage in normal road traffic. You don't always have to race - sometimes an oil slick, wet leaves or other road users are enough to cause a crash. Precautions also help against this!
