2014 GasGas 450 Rally bike.

We do know the ICO will be flawless!!!

Yeah, I did notice it earlier and thought that it was both funny and a testament that it is still alive and well in 2014.

Crush hub....interesting...I thought that bike looked "very production" based.

When looking at the pictures at http://www.gasgasmotos.es/ it looks like the Raid bike is based on the earlier 450 frame using the "B" profile tubes. The 2014 EC450 uses another frame without the "B" profile tubes. The "B" frame profiles with ?hlins were used in the four stroke range up to 2013. I think that is the reason for keeping the ?hlins on the Raid. Perhaps the Reiger doesn't fit the earlier frame designs so well.

What do you mean by crush hub? The silentblocks?
They sound very useful on such a bike.

I meant to say "cush" hub, meaning, it has those little rubber blocks to dampen shock between sprocket and hub. My old Honda trail 90 and 110 had this type of drive system. I just find it odd that a high horse power offroad dirt bike / raid rally bike would use this type of system. But then again, I've never rode or seen a rally bike up close.

I had a Cush drive on my street bike with my carbon fibre wheels, most ducati's also have Cush drives along with other single side swing armed bikes.its meant to relieve the stress on the rear hub by damping the forces from a handful of throttle. I've never seen Cush drives on dirt bikes though(not to say there aren't any)

I agree!

Some KTM dirt bikes have cush drives. Any bike that is ridden on the street/asphalt has (or at the least should have) rubber dampers. Even Marchesini Magnesium wheels on 2t road race bikes have the dampers. It saves the transmission during power pulses and down shifts, as the lash in the trans gets a bit extreme with solid grip on asphalt.

The rally bikes might have them due to chances of spending time on tarmac, thereby preventing extreme trans lash and preserving chain life and clutch wear.
