SafariBerg has raced F.I. Bergs for many years and hundreds of hours in rallies. - If I am recalling correctly, in last years Dakar his team ran a dual fuel pump set-up. An external pump could be used as a back-up in case of a failure of the in-tank pump.

A break at the bracket attachment point (a common failure point) will not compromise the tank itself. Honda knows what they are doing and will not have amateurish failures.

Good eye - that is a really nice detail...

Actually, I was not referring to the rear tanks, but the front ones. Yamaha has problems on their 15L front tanks, rears were always fine. Perhaps with the smaller capacity, i.e. less shaking weight, the supports where the screws go through won't crack...

Those side tanks are going to ceate a lot of leverage on the frame.

I hope they have more modern plastic ones coming

By all accounts the balance and stability is good, they will probably be running with these next week, but who knows in 3 months, there are a lot of technical brains on this, but sometimes the need to prove something doesn't work also, so we really don't know, but should by Jan 5th

I just read the report from the Dakar route crew for the first 7 stages. It looks like they are going to push the bikes to 15,000 ft on stage 3 or 4.

Coming back to the EFI issue, if you have to start a stage at sea level, go to 15,000 ft, then come back to sea level by the end of the stage, .... seems that EFI would have it's advantages!

I ride in the Peruvian Andes for a living with both carb and EFI bikes, and I'll tell you, that if a carb bike is jetted for sea level, by the time I am at 4.5k, it is running VERY rough. That's when I do a quick needle adjustment. When I hit 8,000 I have to break down and change a jet. Again at 13,000 ft.

When I'm riding in the Andes, I am not racing. I can live with a little plug fouling, but NOT IN THE DAKAR! When it is a tour, and I have to re-jet 8 bikes myself, it is REALLY a headache!

With the EFI bike(s) I never even have to think about jetting! SO NICE !

What bikes (and what carbs) are you using?

Isn't there a full stage staying over 4,000m?

These are not HIGH BUDGET adventure rides! My bikes are the standard Honda XR650L, the Brazilian made Honda NX4 (400cc) and the XR250 Tornado, and the Yamaha XTZ 250 Lander (which is EFI). Friends join me at times on their CRF450s and KTM 525s, but those are too high $$ for my beat around tour bikes!

But we have fun, and for very little $$ !

Honda have the option to fit brand new tanks every night so I can't see this even being an issue.
Different matter for a privateer who needs everything to hold up for 9,000kms!

At least they are not made of carbon fibre which threatens to disintergrate at the mere sight of a rocky piste.
Now with such extreme altitude changes 'within' a number of the stages this year, if the EFI works well then Honda could pull out enough of an advantage. Gain a 2 minute and 1 second lead then shadow the closest Alien!
How many days left til DAKAR!

Those route details are definitely a strategy changer... maybe Orange will fit EFI as well this year?

From the map though, stages 1 through 6 look coastal:



Despite the determination to show restraint, Castera and his group still managed to break two records during this fifteen or so reconnaissance trips: “ [...] "Then we also climbed to 4970 metres in altitude. I can't say where but the Dakar has never gone this high before.” For a detailed explanation, we will have to wait until 21 November.

The two Andes crossings are the stage from Calama to Salta (on the 11th) and Fiambala to Copiapo (on the 17th), so I don' think they will start the day at sea level (or even if they will be Specials or Liaisons)

It seems everyone is cheering for the underdog this year.

That's pretty funny !!

I guess with Hondas come back it introduces some more competition which is legitimate.

For a bike that has very limited logos at all, they sure seem to be predominately displayed.
