CRM 250AR
« on: March 27, 2012, 07:04:05 pm »
Just picked up the motor and electrics  out of one of these babies for a reasonable $300, CRM250 AR is interesting in so far is it had servo activated power valve 2 years before the CR250 did and was set up power valve to close further, to harness 'free radicals' in the exhaust gas to boost combustion at low rpm.

Honda built 3 or 4 versions from mid 80s onward and sold them up until quite recently as domestic model in Japan.

Anyways you end up with torquey trail bike engine at the end, which is heading for a blown up 2008 CR450 roller I have in stock. Kind of makes more sense for me trail riding than CR500 motor.

I was just thinking about these today!  ;D
Very interesting bike. Were they ever imported to Oz?
Here's one I shot at the Safari in about '93 I think.

Yes Tony, they were imported to Aus by Honda. I know this because I have 2 of them for sale at the moment! ;D Check out the Discount Motorcycle Wreckers dealer page on Just Bikes site (unashamed plug for me 8)) And they do go well........blew my hat clean off my head!

Well bugger me...........  (figure of speech!!)  ;D ;D
You'd reckon cos they were something different, that they might be worth something one day?

On another subject, is that a KLR600 behind one of the CRM's? If so, how complete is it?
Send me a pm, Paul. Rather than clutter up the CRM thread.

Hoony, may well be his bikes. I got them together and apparently he purchased the last new one available from Honda as a replacement for them because he liked the model so much. :)

Great project Marc!

I figured they'd be a good thing - like a softer-core RMX but without the power valve dramas - but they're all so bloody expensive compared to other things you could buy.

A friend has just finished a CR cylinder conversion for a CRM. Owner sold off all the  Mugen crap which financed the CR cylinder/long rod/Programmable Ignition. NOTHING about the CRM is common with any other Honda, will be a good thing now we have 'de-Honda-ed' it.

In Japan they are still really popular. I have the full wiring loom etc, as the AR is unique engine.... plus gives my trail bike lights from the get go.  I know it sounds a bit poofy but looking for something other than the CR250s power delivery, CRM AR is known for bottom end torque like a 4 stroke, also fuel economy.

Roller is 2008 CR450 with steering damper that arrived without the wheels for $650. Was Motard that went boom.

They are a nice looking bike, and I'd be happy with one in my shed. They pop up on ebay surprisingly often too (the AR and the earlier versions).

Would you believe that the A R stands for Activated Radical... Go the Japs. I miss my one when i am on long rides. It was mega comfortable compared to my next bike which was a regoed yz250 and then a EXCE.

Yeah you see a bit of Mugen stuff kicking about in Japan for them still, it is popular bike still in Japan....the owners dress in MX gear and ride about town standing up. ::)

Even the throttle is quite unique.... has 3 cables coming out, one for the carb and 2 for the oil pump. CDI senses head temperature and controls the power valve with throttle position and head temp as  parameters. The AR is much more like the 2002 onward CR250 engine.
