Jeremy Guarnoni has marked his return to the MRS Kawasaki team in style by topping the FIM Superstock 1000 Championship timesheets in first free practice at Misano.
With the series resuming after skipping both Donington Park and Miller Motorsports Park, Guarnoni's decision to switch from Pedercini Kawasaki to 2011 employers MRS Kawasaki in place of newly promoted Superbike rider Loris Baz showed early dividends as he paced FP1 on the ZX-10R.
Spending much of the session battling it out with wild-card rider Michele Magnoni on the G.M BMW S1000RR, Guarnoni eventually emerged quickest with a time of 1min 40.374secs.
A late effort from BMW Italia rider Lorenzo Baroni lifted the Italian into second position, ahead of S1000RR counterpart Magnoni, while Fabio Massei and Markus Reiterberger made up the remainder of the top five.
Behind them, it was a modest session for title contenders Lorenzo Savadori, Sylvain Barrier and Eddi La Marra as they could only manage late improvements to ninth, eighth and sixth respectively, the trio being split by Marco Bussolotti on the older 1098R rendition of the Ducati in seventh.
Bussolotti's SK Energy team-mate Ondrej Jezek completed the top ten, just edging out newcomer David McFadden on the Pedercini Kawasaki, the South African nonetheless impressing to out-perform his rated team-mate Bryan Staring.
