Pirelli is releasing two sizes of its Diablo Superbike slicks for smaller-displacement sportbikes. There are now 110/70-17 front and 140/70-17 rear options in the size run, made using Pirelli's midrange SC1 compound.

The decision to bring these new sizes to market lies partly in the fact that low-displacement machines are increasingly popular these days, especially among trackday riders and racers. It also comes as a result of Pirelli’s involvement in the FIM World Superbike Championship, which now includes a World Supersport 300 class.

“Pirelli’s racing team has been working hard to develop sizing dedicated to smaller displacement sportbike racing,” said Oscar Solis, Pirelli roadracing manager, in a company press release. “Throughout the past several years the 300cc and 400cc sportbike popularity has continued to trend upward, generating interest as an entry-level racing class and for younger riders who are looking to move up through the ranks. Our testing was extremely positive and we have designed a product to meet the needs and expectations of all skill levels on the racetrack.”

Pirelli aims to provide a similar feel at the rear as the Diablo Supercorsa. But the new front slicks are said to provide better grip and more precise handling.

The SC1 compound is an ideal choice for this class of bikes too because it’s semi-soft, so performs better at lower temperatures but retains enough hardness to work well when temperatures rise. It’s a good middle ground between the softer SC0 and harder SC2.

If you’re interested in snagging a set of the new sizes, check with your Pirelli trackside vendor. Pirelli also plans to attend a number of events for technical support and trackside assistance and will have tires on hand. These include the Florida Motorcycle Road Racing Association’s February 9 race at Palm Beach International Raceway, the Central Motorcycle Roadracing Association’s February 16 round at MSR Houston, and Chuckwalla Valley Motorcycle Association’s February 23 race at Chuckwalla Valley Raceway.
