moin moin, question to the specialists: what belt(company) would you buy if you had to replace the belt? or do you swear on OEM? I have now seen the 3rd (!) torn accessory belt and it had not even run 300km. assembly was in order and tension probably too. so it is also somehow a quality question and there is plenty of choice on the market, and all are the best! and which best buy now? gruss and thanks ff
