A la veille des essais, et contrairement aux usages, le site Bridgestone est désespérément vide de toute information concernant le Sachsenring.
Il faut dire qu'ils avaient prévus d'y apporter les mêmes pneus qu'Assen, et que Yamaha et Ducati s'en sont "légèrement" induités...
Dunlop debuts new construction at SachsenringDunlop’s Moto2 tyres head to the anti-clockwise Sachsenring in Germany for the eighth round of the Moto2 World Championship on July 6-8, the eni Motorrad Grand Prix Deutschland, where a new construction – the ATR14 – will be debuted.
Left, left, left, and a little right
The Sachsenring is an anti-clockwise track with an abundance of left-hand turns and a sparse sprinkling of right-handers. This means that the left side of Dunlop’s tyres are subject to far more forces than the right side.
For this reason, the circuit sees the first appearance of the year of the W919 dual compound tyre in addition to the debut of the new ATR14 construction, which is designed to replicate some of the qualities of a dual compound tyre from a single tread compound.
The Sachsenring is located near the foothills of the Ore Mountains, near to the border between Germany and the Czech Republic. A lap has numerous elevation changes through its ten left hand and three right hand turns over its 3.671 km.
Dual Compound time
The one-sided demands of the Sachsenring’s layout mean that Dunlop’s W919 dual compound tyre is unleashed. This features both of the Moto2 core compounds – 3854 soft and 3838 hard – on one tyre. This gives the best of both worlds. The 3838 hard can withstand the frequent calls on the left hand side of the tyre at Sachsenring, whilst the 3854 soft means the right hand side of the tyre is immediately ready to deliver good grip for the few times it is called upon over the course of a lap.
The W919 is allocated along with the 3838 hard, forming a Group E Specials allocation for this meeting. The 3838 comes in a new construction, ATR14 which is asymmetric has been developed to overcome the heat build up on the left working side of the tyre, but also to increase the heat in the lesser working right side of the tyre. This tyre will also fall into the Group E specials and is also under evaluation for the Phillip Island GP in October.
The 3838 compound is the harder option core compound. It gives riders at these circuits the confidence to open the throttle early out of the apex and also adds resistance to abrasion and wear.
The season-familiar front allocation of the 717 and 302 compounds will be on advance party duties.
Dunlop’s Moto2 Operations Manager, Clinton Howe:
“The Sachsenring is a technically interesting circuit. The primary consideration is maintaining enough heat in the less used right hand side of the tyre so it can deliver sufficient grip once it’s called on after being cooled down through not being used over the majority of a lap. This means our tyre designers and compound technicians have to consider the tyre’s heat retention properties.
“This is the first time this season that we use our W919 tyre and it’s also the first race where we will use the new ATR14 construction. The ATR14 has been introduced on the back of rider’s feedback from the 2011 season. We hope to give back a little of the stability lost to a dual compound tyres, while keeping a similar amount of confidence while on the edge of the tyre.
“The Sachsenring is another circuit with a lot of up and down to it, which means a rider demands good stability from the tyre construction especially for any downhill braking. In terms of abrasion the circuit is pretty aggressive so wear rates can be quite high, especially when the temperatures are cool or there has been recent rain. Sachsenring’s location means that the weather can be quite variable, so cool temperatures and rain are never too much of a surprise, nor are hot temperatures, and I know which I’d prefer!”
