I have the T-rex sump guard and crash bars (full frame), but I have not used it in anger so no idea how well it would protect the bike, but its very well made and fitted great on my Tenere (I have a 2016 ES) so I have no doubts it will protect well in the event of a spill. I was so impressed with it, that I also bought a c rash bar kit for my wifes FZ07 and also had a close friend buy a crash bar kit for his KTM 996 from them. all, the kits fitted well and seem well made. I am in Texas very near T-rex, we actually went to the shop to buy the bars!! so don't know about shipping to the UK.
