Na, KTM looks too old-school to me.
The Yamaha looks like the Rally bike of the future
It looks like its so far in the future that they haven't finished building it yet ;) To me it looks like there's something missing, like they've forgotten something from the front.

Yamaha have put in a  lot of work to make the rear look really good on that bike... because that's all the competition is going to be seeing  >:D

I'm also fascinated to see that they're running a Rekluse clutch on that Yamaha, if I'm not mistake that's rather unusual on a rally bike. What say you BB?

Ja, that is the first I have seen on a rally bike. The concern is that they don't last the distance. It will be interesting to see if Cyril takes it off or not.

I have ridden with the Rekluse and sold it after one ride.
Some guys like it, I don't.  You can't pop the front as with a normal clutch.

Sometimes, it could be nice for enduros but other than that, I don't know.

Rekluse did not work well on the 650cc + bikes, especially in the sand when running low on revs before e.g. cresting dunes.

The issue was too much torque, clutch got fried.

Recluse make manual clutches too. And their clutch covers are not only very strong, its deeper as well, increasing oil capacity.  So it might not actually be an auto clutch set-up, although it could. Does that make sense?

I have a rekluse on my 300 and reckon its the best thing since sliced bread, not sure why it would not not last. Mine did many races (more than 2 years and a roof of Africa on it) was bought second hand and still strong.

I know they are not often used on Rally bikes.

It pops "clutchless" wheelies like nothing.

...not sure why it would not not last.

The way I read it, it is not the Rekluse mechanism that does not last, but the actual clutch plates, particularly on larger bikes, with a lot of torque, in deep sand going slow....and start slipping.

Yes, will be heavier on plates in high torque low speed applications due to almost continuous "slipping" in that scenario. Once the revs are up a little and the clutch engaged it will wear the same as a "normal" clutch

Yip...if you look at the guys doing stuff like Enduro Cross and hard Enduro, I reckon it is a must have mod...shite, I would not mind one for my KDX (doing tight and woods riding)

IMHO, the Dakar is not technical enough to warrant a Rekluse

Always wondered if the guys in the enduro scene use Rekluse type clutches? Guys like Johnny Walker and Graham Jarvis?

I think it is fast becoming a very long enduro. There were some tough technical sections on this year Dakar, and next year the total distance is much, much shorter.
