This thread is a year old ...
... but given that it didn't really have a definitive answer in it, I just got back from putting a set of Dunlop Q3 on my bike, and the rear was 200/50-17. I questioned this at the shop but they don't have a 200/55-17 so I took it anyhow.
Answer ... Nope. Traction control on level 2 doesn't like it. Moderate acceleration from a stop - well within actual traction limits - results in TC cutting spark erratically.
For now, I put traction control back to level 1, and it seems OK. But obviously this size is outside what the traction control is calibrated for.
In theory, 190/55-17 is closer in rolling diameter to the stock size and I should have insisted on that instead, in the absence of 200/55-17. I haven't decided whether I will get it changed ... likely depends on whether the shop will do anything for me, and that depends on whether they have a use for a 200/50-17 tire with about 80 km on it.
