Purchase advice Yamaha R6

Hello, I’m new in the matter with 2 wheels that officially drive faster than 50Km/h and looking for a good and cheap machine in the field of super sports. I came across the Yamaha R6 and would like to hear from Yamaha experts and R6 riders opinions, reviews and recommendations on what to pay attention to with this machine, which is negative which is particularly positive etc. What is important to me: – Reliability – Maintenance costs should not be paid to a Duc ati kommen – Preis/Leistung – Optik – Leistung – ein volter Sound so mir eine Exhaustrecommendation von R6 Fahrern quite right Which series to recommend I have now thought about R6 from 2003, since I do not want to buy a new box for 8 – 10,000 EUR. I prefer to equip a slightly cheaper one and then with exhaust, turn signals etc. a little better. A friend of mine has a 2003 R6 and recently called Mivv GP carbon slip-on and the sound is sometimes breath-taking I can only say u and that despite DB killer without I like the sound not quite. Thank you and many greetings
