Très belles motos, ma curiosité: je vois que la tête de la première n'appartient pas au K1 mais au K2 ('74, pas 72 parce que la tête des K2 anciens est la même du K1) ou K3,K4 jusq'à SS. C'est juste? :-)
I recognize these bars right away. I installed a bunch of them on these 750's when they were new. Customers loved them and they were cheap because when we sold an ATC90 the customer didn't like the stock bars so we'd swap them and toss the old ATC90 bars in a pile.
