It is not as bad as picture formed in my mind after reading this.
Yes, frame will have a smash from triple clamp contact. If it is too scary, it will need weld repair. If not, fit a pvc pipe section over it.
Front brake and clutch(oem Formula) isn't good. Try negotiate a price discount. So, after all, if it bother you, you can change them.
Good reliable motor, modern good front forks, tubeless rear wheel, easy parts availability, light manobrable front end....sherco bikes have beeing evoluting and 7 years will show improvement for sure.
