2009 RM125 Aluminium frame

[cheese]

Personally I like Ali better cause it doesn't have to be painted and it doesn't rust!

Hmm carbon fibre.........

Carbon fibre would be so ridge, with no fex your soon to lose your fillings.
I also say conversion.. But very nice.

Aluminium alloy is more expensive to produce and fabricate into finished product like bike frames etc than steel.

A well designed aluminium alloy bike frame is substantially lighter than a steel one for the same amount of strength.

The automotive industry is trying to take weight out of vehicles for performance and fuel effeciency reasons.

Soon you will start to see new welding technology introduced into aluminium fabrication so we can all look forward to even lighter, stronger & higher performance motor vehicles incl bikes

Steel isn't so obsolete is it?

Keen to make a streetfighter at home so steel and a MIG would be easier and cheaper. At least to get a first version going, would love to learn to TIG.

no steel is not obsolete for bikes like choppers & low performance farm machinery - but the future is complex metal matrix composites & fabrication process technology development
