Whoever is designing KTM's factory bikes must have been around when Suzuki dominated in the late 70's early 80's, with their double downtube cradle frame.

Steel seems to work fine for Ducati.

What's your point?

KTM's have always been steel as far as I know.

You must like those massively over sized and over priced aluminum units that make it next to impossible to work on without ripping half the bike apart.

I like the way they brought the double down tube up higher, looks like the exhaust port is straight , not off to the side.

there is no weight or strength advantage in using aluminum according to KTM so why spend the extra money? save it and keep developing the 2 stroke.... Evil

Wow, really?

You fell right into the marketing trap of the big four. You probably also think that marijuana is a killer drug and that the world is done in 2012.
The steel frames don't weigh much different than aluminum and they handle much better. I went from KTM to kawi and the kawi feels SO stiff in the corners. This is the same reason road racing bicycles are not aluminum, because they are too stiff and have no flex.

I never really understood why they all went Aluminum frames. Since day one they never saved any weight doing so.

I heard the OEMs found they could buy the aluminum in bulk cheaper than the steel (chromoly, w.e.).

Aluminium has no mechanical advantage over steel for a motorbike frame - in rough terms it's about 1/3 the weight but only 1/3 third the strength and stiffness, so to get an aluminium frame with similar strength and stiffness you have to use three times as much material and bingo, your weight advantage has disappeared...

Also you have to design the aluminium frame with a much larger section hence the 2-3 inch wide main spars on aluminium frames compared to say 1 -2 inch steel tube.

As Butch pointed out dirtbikes haven't gotten any lighter with aluminium frames.

I daresay there are other reasons why the manufacturers went with alloy - perhaps cheaper (steel has increase a lot in the last 5-10 years compared to aluminium), doesn't rust, you eliminate the need to paint the frame therefore saving on manufacturing costs.


BTW you guys are all missing the last "i" in Aluminium... Wink

I actually do believe steel frames allow the bikes to handle better and the rigidity of the aluminum units transfer a lot more bumps and such to the riders body plus in turns they feel like they want to wash a little easier likely due to lack of flex. The only time I feel the aluminum frames have an advantage is from hard landings they seem to stay going in a straight line better and don't deflect after a slam, a tradeoff im happy to give up.

KTM's bikes are the lightest bikes avail and that did it with a STEEL (chromoly) frame? How can this be????? Just because you are told to believe something doesn't mean it's true...... I prefer stell over aluminium any day especially after riding them back to back. KTM must see the benefits in their design

With the "fix-improvement" to the EFI why would you still have an electric start?

aluminum is more along the lines of 1/3 the weight of steel and 1/2 the strength.

Looks like a 250f, I would believe the 350f would have linkage

Steel is also more durable over time than aluminium. Aluminium will crack with repeated stress. Steel will also but at much greater stresses over a longer period of time.

KTM is still testing the linkage. Mike and Tony said in the podcast that Mike rode both bikes for testing purposes. Personally the lack of linkage is one of the things that draws me to KTM in the first place.
