Another option would be the Polisport KTM Supermoto shape front mudguard (the one you'd fit on an EXC if you were running 17 inch wheels)... I have one of these and have offered it up, and it looks like it would fit without modification, other than making sure the bolt holes (you need to drill them as they are not pre-drilled) are positioned with the fender forward rather than aft... it would be snug to radiator, but I think you'll be ok...

As for handling, I'd agree with Adam... I can't see how a high mudguard is going to have any real effect on a 180Kg bike... give it a go?
