Have the KX450F 2014
All stock except the full ProCirquit T5 exhaust. I bought this efter i sold my SXF450 2008. WHAT A DIFFERANCE to the better.
I never felt comfortebe on the KTM but when i ride the KXF first i felt right at home!
Its Very stable, the only is mid-corner that it feels little hesitant , but after i got to know the bike i pulled the forks up 10mm in the clamps and got better cornering.But the BIG thing i noticed that with confidence cornaring isent a problem , you just have to commit and follow thrue then it cornes supergood!
The PC exhaust makes it more linear power but i havent done the ECU mapping, but it is a MUST with a aftermarket exhaus and i will update as sonn ive done it.
I use the bike for Enduro and Trail riding also and the bike is OK for enduro but little too heavy for trailriding, a good thing to do for this is to fit the heaviest flywheel there is from Steahly. It helps stalling and smoother din low RPM (Dont have it myself, but consdered it).
