I'm baaaccccckkkk !!!
My 2004 yz 250, raced through till about '07
Then my KTM 250 sx, raced through till end 2012.
Don't have a "selfie" of the new KTM yet.
The KTM will outbrake the YZ in an instant.
The KTM has far better suspension...especially forks.
The KTM produces better power, that is adjustable...and yes it makes a difference.
The KTM handles awesome, although the YZ did nothing wrong, maybe the suspension let it down.
I have never had to wait more than 3 days for a KTM part, and I've owned a 50 mini adv, 2x 50 sx's, a 65, a 85, a 250 and now a 300.
I've waited 6 weeks for YZ gearbox bits (blew 3rd).
Reliability is the same, same.
As mentioned in Watsons thread, KTM offer a line up of 2x 50 models, a 65, a 85/105, a 125/150 and 250/300 2t line up, who else offers something that comprehensive.
Did I mention the Hard parts catalogue...better than porn.
I race....if I had my old YZ sitting beside my 300 in the garage and had to choose one for a race day this w/end.....the YZ would not get a look in. Sorry.
Oh, and KTM race and promote their 2t's AT A FACTORY LEVEL.. can't remember the last time Yamaha did that
