(Editors Note: As you’ll see in the opening paragraph, this article was meant for
publication last summer. We apologize for the delay – we “lost” the article somewhere in
the email “ether” but will follow up soon with more articles on the WR!)
Our new 2009 Yamaha WR250R was purchased on August 29th 2009 from House of
Motorcycles in San Diego, CA (619 229-7700). Sean Warner, General Sales Manager
for “the House” as we call it, located the bike and arranged for its delivery and
Kevin Bosley, House’s set-up guy, is the best there is at preparing motorcycles for sale.
He is not only an excellent wrench, but he takes great pride in doing things correctly
right down to filling premium gas where it’s required (like the WR250R). In other words,
Kevin “gives a “s—!”.
The first thing I did when I arrived home from my trip down surface streets was to drain
the oil and install Spectro Platinum 4 Full Synthetic motorcycle oil (15w-50). Jim Hackl,
President of Millinium Technologies, the N.S.C. people recommended full synthetic be
used for break-in of the DR650 in order to avoid vertical cylinder scratches and it
worked so well we decided to do the same for the WR250R.
During the initial 350 miles on the clock, riding in cool mountain air very early in the
morning, miles per gallon figures yielded were, 83.3, 80.7 and 78.8 despite pumping
losses due to higher than ideal gearing for a 200 pound rider.
We can report that this 298 pound MSM handles like a bicycle as it traverses the
twisties. You almost forget that you’re rolling through paved curves on close to full
knobbies. Until we finish the break-in we can’t comment on power charactoristics, but it
feels like getting up to freeway speeds and maintaining them is no problem. Stay tuned.
We have ordered a muffler tip which flows more air, and a UNI air filter to replace the
more restrictive stock unit; but again, until the motor is broken in completely and we’ve
re-geared, we can’t give a definitive report on power. Once the engine hits 1,000 miles
we’ll begin seriously explaining its capabilities.
As is usual in multisurface street legal motorcycles, suspension components are not
serious dirt stuff and the WR250R is no exception. The front forks are previous
generation 46mm upside down cartridge from Kayaba and the rear shock is a cheap
copy of the Kayaba.
Will Decker of Enzo Racing recommended that we break-in the front forks and that with
correct rebound and compression settings, they might work well enough for trail riding.
Enzo became famous for being a top tuner of Japanese motorcycle suspensions,
especially Kayaba, so we’ll follow Will’s advice.
House of Motorcycles Parts Department is “turning to” for us. Brent Athy was not too
busy the day we purchased the new bike so was able to look up part numbers for:
- 19mm bar risers (the stock bars are great, but a little low for tall folks)
- Factory optional less restrictive muffler tip
- Factory Service manual
Michael Hlavka researched the availability for the factory rear rack which he had to chase
back to Japan. He arranged for one to be delivered in early October when general
availability should be normal.
I also want to thank parts man extraordinaire Henry Nottingham who is helping me solve an
oil filter problem relating to the WR250R, but more about that later.
We will soon have more in depth developmental coverage of the WR250R on
Technical Insights on this website.
