Four days of riding and I killed the YAMAHA skidplate. Any suggestions for a sturdy PLASTIC skid plate? Is the YAMAH plate ok and I just had bad luck? It's only 50$, thats sensibel tome http://www.boats.net/parts/detail/yamaha/Y-1DX-2147A-00-00.html I'd like to steer clear of aluminum plate because of noise. Would a '07 - '11 WR450F skid plate (off ebay) fit a 2012 WR450F frame?
