I have found Mark`s site many years ago. Mark is a true motorcycle artist. Since those times, until nowadays, his work was a continuous inspiration for me. DBBP site is one of my favourites. Please check his work out ,as often as you can. The site is updated weekly. The link is in my link list also.
Check out this new blog. It belongs to a good friend of mine. He is preparing his Kawasaki Z1000 ST for old school racing. The link is here and in my link list. Don`t forget to check his blog often for updates on the bike.
