I didn't think it was particularly heavy, although I didn't think to weigh it. I have another option though, for those not skilled at bending mesh etc. New products for Superbike Source - just arrived and not even on the website yet: Radiator guards!!

I just checked, and they weigh in at a smidgen over 200 grams, including the plastic packaging, foam padding and cable ties! Special offer for TT members, $70 pickup, or $80 posted. R6 and ZX10R in stock; others available soon and on request.
