I have a wr450 04. Its a great bike, but I reckoned it could lose a few pounds, (as could I!) so went about changing a few items for aftermarket "lighter" ones. The std exhaust can went, replaced by a titanium akropovich one, that wakes the dead now! It sis indeed save a few pounds, but not as much as I thought it would. I junked a load fo the liht brackets and indicators etc and shaved a few pounds there. Then I decided to treat myself, to a new set of tripple clamps and tag t2 bars. Just stripped off the old top clamp and offered up the RG3 I got for it! &%$#@!, the standard clamp is WAY lighter than the RG3!! OK I am sure I have strength benefits perhaps, and there is the rubber mounting, but I am amazed at how light the std clamp is! Is it mag ally or just cheap and light! Morale is, don't knock stock!!
