When these tyres were new they provided excellent grip levels for the road in both wet and dry conditions. I did have to re - adjust my suspension to make the bike feel right as the tyres felt vastly different from the Michelin Pilot Sports they replaced.
They were plenty good enough for road use but the rear was especially nervous on a track day giving very little warning before highside ( I saved it that time).
I found the wear rate on these tyres to be heavier than most, they were both well past their best within 3000 miles.
The rear would break free very easily unless really well warmed up, and the front had become mis-shaped like a 20 pence piece (as most dual compound fronts seem to do with me). Both tyres seemed to lack feel at this point even though they were not on the tread wear limit, causing the handling to suffer.
I let my mate have a ride one day after he got fet up of my whining when I couldn't keep up. A few minutes later he threw the bike down the road as the rear came round on him on a roundabout (just as I told him).
By 4000 mile both tyres were on the wear bars, the front was more in the sides than the middle, and the handling had become a joke.
I wouldn't buy these again, I wouldn't have got them in the first place as I have crashed on Bridgestones (BT50's) before. They were free though because my girlfriend at the time worked for a bike magazine and wanted someone to test them. Expensive test as my mate never paid for all the damage he did to my then 2 year old bike.
