as the tital says just got a copy of it, out of interest

[IndigoSteve]

Thanks for the heads up - I'm off out to grab one now! :woohoo:

You'll find it very informative.

There's a test of the new CCM in it.

Apparently it has a 'revolutionary' 'alloy' frame.

That's a scoop...CCM always maintained it had a plastic/composite frame.

You live and learn...thank goodness MCN is around to correct our misconceptions.

Forged aluminium I believe.

Thought it was some sort of funky resin frame ??

So did I...I thought they were using the materials technology developed from the Yam-engined MX GP bike of a few years back.

But it seems I was wrong

Thing is I've got a motorcycle trade publication in front of me with a report from the NEC show...and Austin Clews is quoted as saying "the composite, bonded chassis...has been in development for the last four years and has been well and truly tested in motocross"

I've not seen the thing in the flesh now, but can someone who has confirm what it's actually made of?

Or maybe the frame has been redeveloped in aluminium for some reason...which might explain the delays in delivering the first batch of customer bikes?

No matter, it's an interesting bike and I hope it does well for them.

If it is be interesting to find out why it was changed

[Richard Simpson]

I wonder if it's to do with ease of repair...but aluminium is more difficult to repair than steel would be in an out-of-the way place.

Mond yzf probably knows better than me on this, but I thought that weight-for-weight aluminium and steel were pretty much on a par...obviously what aluminium v what steel?

Be interested in his professional opinion on this...

NB please nobody think this is me having a go at CCM...it's the technicality that interests me not points-scoring.

My understanding of frame technology is that it's easier to tailor the amount of flex you build in and where exactly it happens with an aluminium frame than it is with steel.

What I'd love to see is a fabricated titanium frame but the cost would be astronomical. From what I can remember about titanium production it goes down a grade every time they pour it with the top grade stuff being used for aeronautical work and then it goes down hill through automotive products and the worst of the worst ends up as jewellery. It's also an absolute swine to machine and to weld but the end results are always impressive if they're done right.
