Merhaba,
According to the map,some best colors of turkey seems outside..This is generally once in a life journey so I guess will be good to have your Turkey route as detailed below.Here goes my personal idea..

Nothing interesting in blacksea coastline except sumela monastry in trabzon..boring traffic ,many small towns and traffic lights..better take the road to south from samsun...Also ankara,being a capital city,is also boring and nothing interesting except some big museums..
After making georgia gate to samsun..
1-Samsun (fish restaurants) çorum (capital of hittites)ankara, aksaray (salt lake) cappadocia
2-Cappadocia,konya (center of sufism and mevlana),egridir lake.(old turkish natural life)
3-eğridir denizli,pamukkale(cotton castle! hot springs spa.)
4-Pamukkale-selçuk.(ephesus and st.mary hill here)
5-Selçuk,izmir,ayvalık,asos,babakale.(westernmost point of main asia continent and get your certificate by the headman of the vilage, Mr.Mustafa..nice small seaside village)
6-Asos,troy,çanakkale,galipoli.
7-gallipoli istanbul by the seaside.
8-9- mınımum 2 days to discover istanbul.
10-İstanbul-edirne-kapıkule gate.(just 2-3 hours)

tips..:
1-gas is most expensive here.now about 2 usd.per liter..many campsites and free camping areas availabe on this route..Salt lake,gallipoli anzac bay,etc.
2-several bikers festivals available in some cities during summer months and its a good opportunity for free entertainment,camping, and overall getting to know locals and the country better..Below are the photos for 2015-festival schedule and asia certificate..( I believe will be a good memory)

All the best.
