WorldSBK returns to Brno: Pirelli bring three new development solutions to face the track, which offers poor grip and is demanding for the front end

The Italian brand returns to race on the Czech circuit, which was resurfaced last time in 2008, after a six-year absence from the production bike derived series

Brno (Czech Republic), 4 June 2018 - The MOTUL FIM Superbike World Championship makes a stop in the Czech Republic, at Brno, for the seventh round which also represents passing the half way point of the 2018 season. The circuit returns to host the pinnacle of production machine racing for the eleventh time… and after six years of absence.
 
The track was re-paved for the last time in 2008 and for this reason nowadays it offers a poor level of natural grip. To compensate for the lack of grip, and considering the fact that due to its layout it is rather demanding on front tyres, Pirelli arrives at this round with two new development front solutions in medium compound (ie alternatives to the standard SC2), one for the WorldSBK class and one for WorldSSP, and a new soft compound rear tyre for WorldSBK.
The two new front compounds have been designed with the intent, in both classes, to offer greater solidity and precision compared to the standard SC2, ensuring more even wear and greater grip. As for the new X175 rear slick solution, it is part of a Pirelli development plan to evaluate the performance of the tyres in the size 200/65. At Imola and Donington, Pirelli brought the W1002 solution that used the soft compound of the development W1050. In this respect the X0175 is identical to the W1002, thus presenting itself in the increased 200/65 size but compared to the W1050 it uses the compound of the standard SC0. It will therefore be interesting for Pirelli to understand, with the same SC0 compound, if the riders prefer to opt for the standard solution rather than the X0175 development solution.
 
The circuit of Brno is located 14 km north-west of the homonymous city of the Czech Republic. This track, like other European circuits, was originally born in the 20s as a route of almost 30 km on roads usually open to traffic to host car competitions.
After the Second World War, and over the years to follow, the track was progressively shortened and, starting from 1950, began to host motorcycle competitions.
To comply with the increasingly stringent safety standards imposed to the circuits, in 1987 the permanent racetrack which today everyone knows as the Circuit of Brno was built. The track is one of the longest on the calendar with its 5403 metres. It has 8 right hand corners and 6 left, and the longest straight measures 636 metres. The track has a width of 15 metres with a maximum difference in height of 73 metres, a maximum ascending slope of 7% and a 5% downhill gradient.
 
Brno is a particularly demanding track for front tyres, especially in the right-hand corners, and very high asphalt temperatures can be recorded, especially in the summer months. After the start the riders face a hairpin bend to the right and then immediately a curve to the left before pushing hard to accelerate to top speed in a straight stretch about half a kilometre long which begins to rise slightly, then finish slightly downhill. At the end of this straight there is a left-right chicane, another straight (in this case downhill) and then 5 corners called Stadion (with 3 curves on the right and 2 on the left). A third downhill straight follows, at the end of which the hairpin Kevin Schwantz is tackled. At this point a slight climb starts before another left-right chicane,  followed by a last uphill straight which ends with the final S-curve which precedes the finish line.
 
The solutions for the WorldSBK and WorldSSP classes
 
Pirelli brings a total of 4776 tyres to Brno to meet the needs of all four classes participating in the Czech round. In addition to dry solutions, in the event of bad weather rain tyres are always provided and, for the WorldSBK and WorldSSP categories, also intermediate tyres.
 
In WorldSBK the riders will have eight dry solutions, four for the front and as many for the rear, as well as the supersoft qualifier tyre to be used in the second Superpole® session.
Among the solutions provided for the front, three have already been used by the riders in the previous rounds: we are talking about the standard SC1 and SC2 and the development SC1 V0952, the latter very much appreciated by the riders in all the rounds raced this year. The unique development SC2 X0605, a solution with a rather rigid compound which, compared to the standard SC2, offers greater solidity and precision, so should guarantee a more homogeneous wear and better grip.
As for the rear, the riders will have three solutions in soft compound and one in medium compound. The three soft compounds are: the standard SC0, which until now has been brought in the round of Buriram and Donington Park, the W1050, which compared to the standard SC0 is generally more suitable for cold temperatures, and the new X0175 which makes its debut in Brno. This uses the same compound as the standard SC0 but presents itself in the innovative 200/65 size which offers a wider contact area, consequently giving better distribution of energy. This solution, compared to the W1002 already used by riders at Imola and Misano, differs for the compound used, which in this case is that of the standard SC0 and not that of the W1050. The last option is represented by the standard SC1.
 
In WorldSSP, there are four solutions for the front and three for the rear. At the front standard SC1 and SC2 are supported by the soft development solution X0012 and by the new development SC2 X0582 designed to offer greater grip and more contained wear than the standard SC2.
At the rear the standard SC0 will be joined by the development SC0 X0497, which compared to the standard solution should offer better resistance and consistent performance, and from the development SC1 X0093, designed to offer a high consistency of performance and limited wear especially with low temperatures and already brought by Pirelli also to Aragón and Assen.
