| Well, I read somewhere recently whilst looking about for tyres for myself, that Rennsports are the same as the Pirelli SC's...same structure, compounds etc...just a different tread patterm, as Pirelli bought metzler sometime ago, and let them continue manufacturing under the rennsport name..dunno how true that is...but worth bearing in mind.
I would suggest having used only the diablos, that if you only ride in the dry, the diablo corsa in a 180 section (providing you have a 5.5 inch rear, not a 6 inch) would be the best option. Stickier than 99% of riders capabilites and good for 2500 miles. |
