That sucks if Pirelli riders arent getting the support they deserve, the new 200/60 slick and 200 series DOT race tire are unbelievable having worked with a rider in Utah with them. MMP (East track) has always been hard on the left side of the tire and with the new profile and compounds, which are streets ahead of the old design, I would put them up against any tire out there right now. Sure running the right pressures makes a big difference but with the new compounds they work even better than when I used them and won a race or two 8)
