Pirelli again relies on new larger size solutions for the Assen round of the MOTUL FIM Superbike World Championship
In the WorldSSP class, the new standard SC1 tyre and a new 190/60 development solution enter the scene as options for the rear
After the round at MotorLand Aragón last weekend, the MOTUL FIM Superbike World Championship moves to the Netherlands for round four at the historic TT Circuit Assen.
Again at this event as per the last round at MotorLand Aragón, Pirelli has decided to rely exclusively on new larger size solutions in the WSBK class, 125/70 for the front and 200/65 for the rear, which are ensuring very high performance and receiving positive comments from all riders.
In the WorldSSP class, there will be two new additions to the rear: the first is represented by the new standard SC1, the second by the development solution Y0328 in soft compound (which comes in the larger size 190/60, instead of the classic 180/60) which should offer greater stability and longevity of performance.
The TT Circuit Assen is considered one of the most difficult tracks in the championship and is nicknamed ‘The Cathedral of Speed’ due to the high average speed riders can reach. The circuit was built in 1925 and now measures 4,542 metres with 11 right-handers and 6 left turns.
Although not particularly stressed from a thermal point of view, the tyres must still be able to provide to the rider great precision and a lot of directional stability. In April, teams can be greeted by varying weather conditions and cooler temperatures and this is another factor to take into consideration.
The Assen allure lies in this series of long and constant speed turns, slow U-shaped turns with braking and sudden acceleration, fast chicanes and long turns with strong acceleration coming out of them, with the bike still leaned over.
Made up of a very high bituminous percentage, the asphalt at Assen represents a strong correlation between how aggressive the track is and the air temperature. This means that with low temperatures the rear solutions can suffer from problems with tearing (by now well known as cold tearing), particularly in the event of soft solution usage (and therefore less resistant) and when the track is poorly rubberised, typically during the Friday sessions.
The solutions for the WorldSBK and WorldSSP classes:
Pirelli brings 3672 tyres to Assen. As in all rounds, in case of bad weather in addition to dry tyres (slick or carved according to the class) they can count on intermediate or full wet solutions based on the amount of water present on the asphalt.
In the WorldSBK class, the riders will once again have access to only the 125/70 front and 200/65 rear larger size tyres, the same ones already on the track at MotorLand Aragón during the first European round.
The front options are three, one in a soft compound and two in a medium compound: the standard SC1 of the 125/70 range is the soft compound solution, the development SC2 X1071 and X1118 are the two choices in the medium compound, both developed in order to offer good grip and stability.
As for the rear options, in addition to the standard SC0 in 200/65 size, the development SC0 X0914, which offers a more solid structure that helps to ensure greater stability and more thrust, and the development SC1 Y0187, which could be the ideal solution for the first weekend sessions when the asphalt is more dirty and aggressive or in case of particularly low temperatures, will again be present.
In addition to these solutions, at the rear the riders will have at their disposal the SCX tyre in the Y0309 specification and in super soft compound, which can be used during the qualifying sessions in preparation for the use of the only Superpole® tyre available to riders who completes the availability of rear tyres.
In the WorldSSP600 category, the riders will have five dry solutions to choose from, two front and three rear. For the front, there will be, as at Aragon, the standard SC1 and the development SC2 X0582 which compared to the standard SC2 offers greater grip and a lower wear. At the rear, two solutions in soft and one in medium compound. The medium compound solution is represented by the new standard SC1 which, as in the case of the Superbike, could be the ideal solution for the first weekend sessions when the asphalt is more dirty and aggressive or if the temperatures are too low to use the two soft solutions. The latter are the X0633, introduced last year at Misano and also brought to Portimão, Magny-Cours, San Juan Villicum and Losail, and the brand new Y0328, which Pirelli has built in 190/60 larger sizein order to achieve greater stability and a superior longevity.
