From Silverstone to Misano: it is hard to think of a starker contrast in circuits. Silverstone sits atop a windswept hilltop in the center of England, surrounded by verdant valleys and ancient villages. Misano nestles just above the vast string of late 20th Century hotel blocks, which form Italy’s Adriatic Riviera.

Silverstone is often wet, and usually cold, no matter what time of year we go there. Misano swelters in the heat of a late Italian summer.

The tracks are very different too. Silverstone is a vast, sweeping expanse of fast and challenging tarmac. Misano is a tightly compressed complex of loops demanding more of fuel management, than of the rider.

Silverstone has old, worn, slippery tarmac with huge bumps rippled in by F1 and other car racing. Up until 2015, Misano was much the same. But it was resurfaced last year, and has fresh, dark, smooth asphalt that has a lot more grip than the old surface.

So the MotoGP riders face a very different kettle of fish a week after Silverstone. The layout of the track is likely to have the biggest impact.

Where Silverstone is full of fast third and fourth gear corners which riders enter carrying a lot of speed, most of the turns at Misano are all first and second gear. Drive and traction are the watchwords, though there are three or four corners where braking is at a premium as well.

At the San Marino GP today, MotoGP officially retired the use of #58, giving honor to Marco Simoncelli, who died almost five years ago while racing in the Malaysian GP at Sepang.

Of course, this weekend’s stop on the MotoGP Championship calendar actually takes place at the Misano World Circuit, which changed its official name to the the “Misano World Circuit – Marco Simoncelli” in order to honor the fallen racer.

This makes the San Marino GP a fitting venue for Simoncelli’s number to be retired, and of course the weekend’s events take place in front of a home crowd, with Simoncelli born just a few miles away on the coast, in Cattolica.

AGV is at the San Marino GP this week, showing off its latest racing helmet design. As you can tell from the photo above, the AGV Pista GP R is an evolution on the AGV Pista GP, with AGV claiming that “R” has better aerodynamics, venting, and field of view over its predecessor.

More significant changes come in the form of a Pinlock that comes as standard, along with revised spoiler and visor locking system designs.

The reason though we are bringing you this story today though is that the AGV Pista GP R has the first integrated hydration channel, straight from the factory.

The FIM have released another provisional calendar for the MotoGP series, in response to yet another shake up of the F1 calendar by Bernie Ecclestone.

With F1 and MotoGP having an informal agreement not to have their dates clash, and with MotoGP losing out in terms of TV audience whenever they do, the MotoGP calendar released in September had too many conflicts with F1. As a result of those clashes, four races have now been moved to different dates.

The German Grand Prix at the Sachsenring has been shifted back a week to July 17th. Silverstone, scheduled to be held on the 17th, has been moved to the September 4th. The Malaysian Grand Prix at Sepang has been moved from the start to the end of the Asia-Pacific triple header, and will now be run on October 20th. That shift means that the Valencia race has been pushed back a week, to November 13th.

With the flyaways fast approaching, MotoGP’s silly season for 2016 is reaching its climax. All of the factory seats are taken – including the seat at Aprilia vacated by Marco Melandri – and the top satellite rides are filled as well, either officially or unofficially.

A few pieces of the puzzle remain, but fitting those together is more or less complex, depending on the team and the rider involved. Here’s a look at where we stand so far.

A race that people will certainly be talking about weeks from now, the boys are back on the mics for the San Marino GP – dissecting the various weather strategies and their impact on the 2015 championship.

You won’t want to miss this half-hour discussion by David Emmett (MotoMatters), Neil Morrison (Crash.net & RoadRacing World), and Tony Goldsmith (A&R and BikeSportNews).

On a technical note, we’ve got some proper microphones for the lads on this show. Hopefully you’ll notice an improvement in our show quality. We’re really close to having a dedicated site ready, along with an RSS feed, iTunes updates, etc. So, thanks for bearing with us on that front.

For reasons too obvious to mention, motorcycle gear protection has been on my mind lately. Though my broken collarbone is unfortunate, it is timely, as Dainese just released its D-Air Misano 1000 jacket, the world’s first commercially available self-contained airbag jacket for motorcyclists.

Let’s be really clear about one thing: this is a sea change for motorcycle safety.

Debuting at the San Marino GP, the venue for the Dainese D-Air Misano 1000’s release is no mistake, as the jacket builds off the Italian company’s experience with airbag suits in the MotoGP World Championship.

At the highest level of racing, airbag technology has become a game-changing technology, and now riders on the street can use essentially that same airbag system, that same proprietary crash-sensing software (modified for street use), and that same company history of safety that the professionals rely on while on the race track.

Racers are gamblers. That their helmet designs featuring dice, cards, and other gambling paraphernalia bear witness to that. They have to be gamblers, a willingness to take risks is a prerequisite to being fast on a motorcycle, running the odds through your mind and betting the house on your own ability to get the upper hand.

Sometimes the gamble pays off, and when it does, the rewards are bountiful. Other times, however, you lose, leaving you a hard, hard row to hoe. There are gambles to be taken at every MotoGP race, but Misano turned into the biggest casino the series has ever seen.

Rain that came after the start then stopped again meant gambling on the right time to come in for tires – twice, once to go from slicks to wets, once to go from wets to slicks – left some riders reaping rich rewards, while others were left with empty hands.

Come in too late for wets, and you could lose 10 seconds wobbling round on a wet track on slicks. Come in too late for slicks, and you could lose 10 seconds or more a lap trying to find grip on wet tires as they were tearing themselves apart.

Marc Marquez wheelies past his crew after winning the Grand Prix of San Marino.

A fantastic ride by Bradley Smith. When everyone else changed to their wet setup bike he stayed out on slicks. The gamble paid off as he finished 2nd.

Scott Redding picked himself up off the floor to claim 3rd place and his debut MotoGP podium.
