Hi Adam,
When I collected my MC it was a cold, drizzly December day and I found the MPSS tyres fitted hopeless, although they were great on warmer dry days.
Anyway I changed the 19" CSL Reps for a set of 224s and had a set of Kumho Ecstas fitted which performed much better in the cold and damp, and I found them equally capable on the road in good conditions. Set of 4 cost £400 from Black Circles in April 2021.
Then last year I needed new rear tyres for a trip to Scotland as I was expecting some rain (wasn't disappointed) and got a pair of Hankook Ventus fitted which were a step up from the Kumhos in the wet and just as good in the dry. They were £292 for the pair in May 2025, although I did go up a size for 265/40s.
I know these are both mid-range brands but for road use I found them fine, but everyone tends to have their own preferences so expect a range of answers!
