Help pls - Yamaha R1 Axles - what are they made from ????

[Hewie]

Gday All

I need to find out exactly what the axles on a 2004 - 2006 R1 are made from and if they are heat treated etc.

Ive been searching ut cant find any material data on them.

Does anyone know what they are made from please ?

Cheers

sorry, not a helpfull post... why? are you making some?

if i had to guess id say something decent like 4140, but then again its probably closer to a high tensile bolt (grade 10.9 or so)

Edit: have a look in here, not exactly your info, but similar.

You could have one analysed...

Will cost a little but they will tell you exactly what it is...

^WHS
Metlabs should be able to tell you, or point you in the right direction.

Making your own?

I'm with paraletic.. some kind of high tensile, 4140 or 4340... doubt they'd be heat treated.
I cant remember what veetwo made their axle's from, but I could find out if ya want...

Ask Gav when you see him, man knows his metallurgy.
