After months of
waiting we finally got to throw a leg over Yamaha's all new electric start
2003 WR 250F. Just as Yamaha made everyone play catch up in 1998 with
their release of the high performance YZ400 four-stroke, they've done it
again but this time in the middleweight 250 class. It's electric start and
engine that revs to the moon with excellent handling make it a formidable
off road machine. You can literally hop on this bike and within a few
turns be comfortable enough to ride it fast.
Pushing the start
button brings the WR to life with a quiet exhaust note. Then a quick twist
of the throttle lets you know this isn't your daddy's 4-stroke as the
engine revs to 13,500 RPM. Put her in gear dump the clutch and hang on!
I'm a pretty big guy at 6'0" 215 pounds in my birthday suit and the
WR250 just about yanked my arms from the sockets when it hit the power
Besides having an
almost 2-stroke like punch the suspension works well and the horizontal
seat let's the rider make rear to front seat movement effortlessly. You do
however pay a price for the ease of seat transition with a somewhat firm
seat. Smaller riders will be at home with the riders compartment but
bigger riders will find it somewhat cramped. Ride it like you stole it
types will absolutely love the way the WR250F likes to be ridden, high in
the RPM's and in full attack position. Less aggressive riders will also
like this machine with its nice suspension, handling, quick turning
ability and supple low-end power.
As with its big
brother the WR450F, the bone stock WR250F does need some tinkering to
impress you. To import the WR's from Japan Yamaha must meet a boatload of
requirements so, yes, you guessed it, bog city as delivered from the
showroom. Even though the stock bike is castrated it still does not meet
the standards in California to receive a green sticker. For those wishing
for more power then the stock machine delivers Yamaha has you covered.
Your first two modifications are free, remove the throttle stop and boot
from the air box. The next one will cost you $39.95.
requirements (96dBa) limit you from running a wide-open exhaust so
Yamaha's "GYT-R" came up with a muffler insert that keeps the
noise level below the standard and makes more horsepower then the tiny OEM
insert. Yamaha dealers should have the trick looking inserts in stock,
part number GYT-5TJ93-75-00 (muffler insert). With these modifications and
a skid plate for off road use this one nice off road weapon!
In 2003 the WR 250F
didn't get all of the upgrades of the YZ 250F but did get an electric
start so the trade off will make most off road's happy.
