Riding in the wet

[Grahamm]

This might highlight my inexperience but does clutch control come into any of this?

Not really (but it's not a silly question, however not asking it because you don't want to admit you don't know would be silly )

Clutch control pretty much only ever comes in at very low speeds, eg slipping it whilst keeping the revs up is useful for filtering slowly through traffic or when pulling out of T-junctions etc.

At speed, the clutch can smooth out the change when you're using engine braking, but these days that's only recommended for slowing down in slippery conditions, generally, when changing down you should dip the clutch, put in a touch more revs so the engine speed matches the road speed, then blend the clutch back in.

This avoids that sudden lurch when you take a lower gear, dump the clutch and the back wheel is suddenly running faster than the engine which could result in a destabilising lock-up, especially when it's wet.
