While obviously it's not motorway, the dual carriage way between Low Fell and A1 is pretty much flat out, as is between CLS and Pity Me, then between Durham and Croxdale, then it's fast A roads between Middlestone Moor and Coundon

Low Fell to A1 can't be more than a mile and I'm sure it's 40mph limit. A167 from Chester to Durham is 50 and the Angel's cope well enough with that. After Neville's Cross to Tudhoe is national speed limit and Middlestone Moor to Bishop is too which is fair enough. I wouldn't say any of them are particularly long stretches flat out - certainly compared to what the B5s used to operate. The X84/85 probably spends longer flat out than the X21 at any point.

In all honesty, I don't see any reason when any bus should have an issue with the X21, other than that the StreetDecks which used to be on them seem to have been fairly problematic no matter where they've been put and as already mentioned, the B5s have been flogged on the X10 like the B9s were before that.
