Jules Cluzel had the honour of topping the first official World Supersport Championship session to be held around the brand-new Moscow Raceway as a day of group testing got underway ahead of this weekend's inaugural event.

With two sessions for both the Supersport and Superbike classes being held to help the riders acclimatise to the recently-built venue, Cluzel - a winner last time out at Silverstone - adapted best to the twisty Russian circuit to emerge top of the 60 minute session.

With lap times understandably coming down quickly throughout the session, Cluzel would eventually go quickest with a best of 1min 40.370secs, putting him a clear six tenths up on PTR counterpart and fellow front runner Sam Lowes.

In fact, despite the circuit being an unknown quantity, the top ten mostly reflected the general order of this year's championship, with the likes of Broc Parkes in third place and Fabien Foret in fifth.

Fresh from his most convincing race weekend of the season at Silverstone, Mathew Scholtz made it a Honda 1-2-3-4 in fourth, ahead of Foret - who suffered a fall -, while Alex Baldolini got his Triumph into the upper echelons with a run to sixth place.

Having topped the timesheets early on, Ronan Quarmby settled for an eventual seventh place on the third of the PTR Hondas, ahead of former 125GP champion Gabor Talmacsi on the privateer ProRace CBR600RR.

Sheridan Morais set the pace for the factory Kawasaki team in ninth, ahead of Roberto Tamburini and Kenan Sofuoglu, the championship leader around two seconds off the ultimate pace, while home favourite Vladimir Leonov was 12th quickest.
