I posted this in my
ongoing photo thread of rides and mods but thought it probably belongs here too. I did a forum search and didn't see anything posted about this part previously.
A couple of weeks ago I read a post over on ADVrider where someone fitted a TM Designworks rear disc guard for YZ/YZF/WRF to their WRR. I checked through some Yamaha OEM parts links and learned that several (but not all) rear brake parts are common to all of these bikes. The stock gray rear caliper guard is one of those parts. So I ordered the TMD rear disc guard via Amazon and received it yesterday. I like it. It's simple, lightweight, and looks like it can take a beating and keep going.
It took me more time to find wrenches and loctite than it did to bolt the caliper guard onto the bike via the 2 supplied bolts. The closest analogy I can think of for the material is colored UHMW. It appears to be tough, flexibly rigid (or rigidly flexible), and the same high density material all the way through. TMD has been using this material for years to make chain sliders, chain guides, and skid plates for most popular motocross bikes.
I like the look of the disc guard enough that I've ordered the matching TMD caliper guard too. But I must confess that the caliper guard is just a cosmetic indulgence, as the stock grey rear caliper guard works just fine.
It's too bad TM Designworks doesn't make parts specifically for the WRR. Their swingarm sliders, chain guides, and skid plates look awesome too.
