Just to add to the on going tyre saga. I dropped my bike off for its running in service this morning (700 miles, RS SE, fitted with PR4's) and picked up a courtesy bike (RS SE, 700 miles, fitted with Metzelers). I set up the courtesy bike to my settings (Road, 1 helmet and luggage and "rain" mode...as it was raining...). So - same settings, same bikes, similar mileage, same over weight, middle aged bald bloke in control.....and the difference was truly amazing.....Metzelers gave the bike a much more light and sporty feel. quicker to change direction, better low speed control (surprisingly, as I filtered along the A50 and M1), no tramlining, nice and stable at speed....and plenty of grip in the wet (much more like T30s or Angel GTs). PR4s feel sluggish and less precise in comparison. Now I know there are debates on longevity/quality of the Metzelers v PR4s .........but my conclusion (based on my limited tyre testing skills!) is that I prefer the Metzelers - they bring the bike to life.......in my opinion, others may disagree!
