Alot of the time a race bike and is better than a bike that's been tagged around fields and never maintained obviously though alot of race bikes do generally get thrashed but are looked after more than some one who just rags around every now and then not serviceing the bike
I also have 2015 kx450f. 1 owner immaculate. I like the black plug map best bc I can tame it an ride it a lil harder like its my 2019kx250f. Im gonna remap the green plug for more aggressive smooth power delivery on top. I use the white plug for racing wich I have to sit on the tank bc I geared 2up rear 1down front and turned my bike into HULK...No cap! Ridiculous stupid fast hole shots with white plug, VP octane boost, an gears done. I now eat up rear tire on this kx450f like my 250 2t.
