ok, so Ive always been curious as to why a dakar style rally bike is set up the way it is. More so the exhaust, why is it slung low? Seems to me that it would be easily damaged. I get the cockpit, they have a lot of crap to shove up there. Why the low fender? seems counter productive. Being as they ride similar terrain as say the baja race, it seems, to me anyway that a bike set up in a similar fashion would be more desireable, aside from larger fuel capacity and the addition of navigational aids. they certainly arent lacking for support, I doubt the riders even carry tools (factory riders anyway), just call in for a tire change, engine change...
Or is it one of those, weve always done it this way but no one knows why kind of deals.

The exhaust path is usually defined by the tanks and since the tanks in these things are Godgilla type running low even from the 660 Rallye days was the norm... May be the length plays a role too ?
The lower fender keeps the sand away from your face, ride with a high fender in sand (with their speeds ) and you will probably get sandblasted for good ... It also adds stability where going 160+ with a fender which looks like a sailing board would be a no-no ... I dont know about Factory riders but the others carry enough tools to get the bike in to bits, change clutch plates, etc ...

160 is what 80mph...meh, Ive done 80 regularly with no problems with a standard dirtbike fender, hell they go faster than that in baja. From the pics the rear fuel tanks dont come anywhere near the stock exhaust.

160kph is 100mph. Low fender also gets more air through the rads and oil cooler. When it's dry, the benfits of the low fender come into play, but when it's going to be wet, they put on the high fender. In Africa there was liitle need for a high fender, but they have been spending more time with high fenders in the Dakar SA. Helder seems to like petite SM front fenders, and used them on his Yamaha as well.

It's the front tanks that prohibit the use of a conventional tucked exhaust.

and the battery and the fuel pump ... all space is utilized causing the need for a low slung muffler.. Ktm is wise and have it protected slightly

The space consideration is for the front tanks. - It also keeps the fuel cooler.

Can you tell me which model R swing arm ?

When you say current Europe Honda kit what are you referring to?

argument for rallyes to switch to 450

so any naysayers here after all this time now? I remember arguing for days about the evolution of the sport, about having no real race and just 2-3 guys making a living at this.
Now....look at it...even Honda is back. I'm so pumped!

Great work led by Judith Tomaselli and hats off to ASO and David Castera for having seen the light and lead the way when really the FIM should have been the one.

Some very discrete manufacturer.
This is the only logo visible (on the jerseys)

All true points, I found it to be a real PITA on the converted enduro bikes I had with it (both KTM 525 with Mecasystem exhausts).

They run great, but they add heat to the engine, foot, and rear brake master, none of which benefit from that, and they are smash-prone if the suspension stop hasn't been adjusted to compensate. That was a big reason I wanted to go with a big Acerbis tank, it seemed like I smashed a pipe every time I went out.

Time will tell how it works on my latest rally bike.
