We were very fond of the DR.D NS- 4 exhaust, because it
spread the power out. This pipe is a great buy.
The DR.D 2014 YZ450F was set up for faster riders looking to nail holeshots and rip through corners. It was a success.
Strangely, there was an elastomer bumper mounted
under the swingarm to function as a top-out device for
the rear shock—something we haven’t seen since Tony
Cairoli raced for Yamaha several years ago.
The MXA test riders liked the rear end but felt that
the front forks were very harsh from the midstroke down.
We clicked out on the compression and rebound, and
that worked well with Enzo’s plusher initial stroke and
ramped-up midstroke. Once dialed in, the forks were
fluid in the small chop and stiff in the big hits.
What else could we asked for? Without going to
the added expense of cracking the engine open, DR.D
addressed MXA’s major complaints about the stock
YZ450F setup, and DR.D will be more than happy to
point you in the right direction too. For more information,
