ADVICE NEEDED: ktm 690 crash bar - 'low tank'

[zebra - Flying Brick]

Hi Guys

need some advice, on a KTM 690 that a customer has built up with (fiber glass) front tanks...

Customer has added front fuel tank ('low' tank, not the high-sitting one) and he wants to protect the tanks with a crash bar, and I am unsure what will fit locally - can get a good few 'standard' 690 crash bars, but now need to search for bars that work with the tank that reaches lower down...

Cheers
