We tried to develop carbon-glass fibre tank protection. We tested it in Ukraine - Karpatian mountains - and I think - it works well. As you can see on attached pictures my KTM after 10 - 15 crashes - protectors are only scratched and tank or fuel valve is in perfect condition. You can see new one pieces too - itīs made from 2.5 mm (thickness) carbon and glass fibre (only surface is made from carbon) For sticking onto fuel tank, I used adhesive Zwaluv High Tack (Den Braven - Mamut glue). Price
of both protectors is 140$ and cost of shipment from Czech rep. to USA is 20$. If anybody wants it - pls send me P.M.
