I am starting to prep my bike for next year's finke desert race, and was wondering if anyone had some knowledge/experience in setting these bad boys up for high speed racing.

Average speed for the race is around 90km/h and top speed is around 160km/h if if both bike and rider are up to it.
Terrain is mainly sandy whoops with a few sections of hard pack and rocks.
Suggestions on gearing, tyre choice, mapping and any engine mods would be appreciated. I already run a full yoshi system which I am very happy with , so I'm all sorted in that regard.

Also, does anyone know of an oversized fuel tank for this model? I can't seem to find any.

Many thanks in advance.

Believe this is one 2.4g option that may work: https://www.imsprodu...SizeSet=2.4 gal

Here's a ride report on my 2012 Finke assault on a 2011 YZ450. Suspension setup by someone who knows Finke is mandatory.

I came 150th in 2012 and 120th this year on a YZ250 2-banger.

Thanks mate.
I will put my bike into desert edge for the suspension, greeny knows his suspension and I seems that all the local boys that do well see him for suspension set up.

It's mainly gearing and tyres I'm concerned about, thinking of running an 18" rear wheel to reduce the risk of a puncture

I just ran a Dunlop D952 in a 120/90-19 at 15psi both years with no drama.

Greeny knows his stuff.

I just ran 15/49 gearing (2 extra on the front from standard) and that was plenty. You need it to be able pull though the heavy sand. It will still do 160 but you won't be doing that sort of speed much. I averaged about 75km/hr this year.

I might drop 1 or 2 off the back sprocket as well, not a huge fan of over rev.
What sort of mapping did you run on the 450?

Good write up on dbw by the way

Thanks mate. I never changed the mapping.
Finkes not about power and speed. It's about endurance and getting through the whoops as quick as you can without eating sh!t.
