From Assen to Sachsenring, 700 kilometers in 7 days. One of the shorter hauls between back-to-back races, but a tight schedule nonetheless.

Sachsenring’s weird split paddock was full of tired looking faces on Thursday, as truck drivers and hospitality staff rushed to tear the entire paddock down in Drenthe, then build it all up again in Saxony.

It is hard to think of a greater contrast in circuits, too. Assen is flat, fast, and sweeping, the Sachsenring tight, slow, and with massive changes in elevation. There are similarities too: the bikes spend a lot of time on the edge of the tire at both tracks.

At Assen, it’s especially the right side of the tire, as riders sweep through the succession of right-handers from Mandeveen all the way to the Ramshoek.

At the Sachsenring, it’s all left-hand side of the tire which takes the punishment, as the bikes come out of the Omegakurve, pitch into Turn 4, then hustle their way all the way down and then up and over the hill before Turn 11.

Turn 11 is a vicious beast, laying in wait for the unwary, its voracious gravel trap waiting to claim anyone who flicks the bike just a little too enthusiastically right after spending so much time on the left-hand side of the tire.

The opposite right-hand side has had 40 seconds to cool off, while the right-hand side of the tire takes all the punishment. The transition from left to right, from scorching hot to cool rubber, from one of the hardest tire compounds of the year to one of the softest, is tricky.

Switching between two very different feeling rubbers catches plenty of riders out, in both MotoGP and Moto2.
