Unfounded observation and SWAG
KTM simply got in an order (maybe 1000s of feet) of shitty fuel line some time during the late '12 production,
It apprears to be worse with the XCW and 450s...
We have 3 2012 riders with no issues and two 450s with multiple strikes. they gave up and bought good high pressure lines and replaced everthing.
Quality control KTM!!!

You dont quit riding when you get old, you get old when you quit riding.
I don't always ride street bikes, but when I do I prefer VStroms
