I've found several posts on these case savers and decided they look like the best protection in case of chain derailment. I ordered one though a local Aus suppleir, when it turned up it clearly didn't fit. They've promised to refund my payment but say that TMD don't make a case saver for my bike. The TM Designworks web site doesn't list a part for the 2003-06 WR450. The TT store however has them for sale https://www.thumpertalk.com/shop/T-M-Designworks-Plastic-Case-Saver-Black-YCS-YFZ-BK-p4107596.html Can someone confirm that the case saver in the TT store will fit a 2005 WR450 as advertised? It's a long way to send it back if it doesn't fit.
