Just before I workout out I wanted a 525 I sold mine to a mate.
Luckily he has a short attention span so I bought it back for the same price. He even serviced the shock and added new plastics and side stand for me


The bike already has an HT racing oil cooler added.
So from the 640 I will take the cush drive rear, tank, fairing.
I was thinking about adding a 540 kit from thumper racing along with a hot cam, and fluidyne radiators.
But first I will get around to putting it together.
