  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

250-500cc WR250/300 POWER LOSS FROM ENGINE TO REAR WHEEL

Does anyone know the correct figures from the engine to rear wheel? What is the power loss? I punched out 42RWHP/26ftlb of torque from my 2008 WR250 on the dyno (used a road tyre/13-49t sprockets) seeking facts and figures

Cheers Col
 
Mate to put that figure in to perspective, a CR500 puts out around 56hp stock...do some pipe mods, 39 or 40mm pwk and port work then expect 65+hp.

My WR360, apparently, only made around 34-38hp.

Your stock 2007 YZ250 pops out around 47hp/30ftlb...but you are comparing a motocross bike to an enduro bike so how the power is delivered determines how 'useable' it is for your riding.


Spend the money on suspension and more riding....unless you're desert racing.
 
My dyno graph showed the same power curve as the 2010 WR300, with 4HP more from my 2008 WR250. The only mods I have is a DEP pipe, FMF TurbineCore2 tail pipe & JD jetting kit fitted to the standard TMX38.
As an enduro bike, this bike is very user friendly.

I'm not comparing motocross to enduro, just the question on what the power loss is through the drive line
