Warning. Politically incorrect stereotype statement follows. It is offensive, probably because there is a grain of truth in it. Warning

In stark contrast to the clinically serious, detailed and obsessive KTM rider who agonizes over every detail, including the micron rating of the aftermarket billet aluminum add on fuel filter (I am not kidding, guilty as charged with my Husaberg, 10 micron by the way) the stereotypical WR 450 rider sports a mullet, guzzles beer and is randomly hit or miss about doing maintenance on his dirt bike. Perhaps Yamaha designed the big WR to stand up to the "care" provided by this audience.

In any case, the WR series (both 250 and 450) has proven over the years to be the most bulletproof dirt bikes on the planet.

Heck, one of the MXers requires the piston pin clips to be changed every 10 hours last I saw.

I don't have much to say on "dirtbikes", but I like it when MO tests and reports on them.

I am not wholly-unfamiliar with sliding about in the dirt, it's just that my skilzorz require an additional pair of wheels.
