What started out as a worldwide service campaign for the water-cooled BMW R1200GS models is turning into a massive global recall for the German motorcycle manufacturer, as now the United States has joined the United Kingdom in issuing a recall on the popular ADV machine.

Accordingly, BMW Motorrad USA has issued a “stop sale” to BMW dealers, as documents for a recall with the National Highway Traffic Safety Administration are being readied for release.

The recall sees BMW Motorrad dealers inspecting the fixed fork tube on R1200GS models produced between November 2013 and June 2017. If the inspected motorcycle has an excessively large gap between the fork pipe and the seal plug, then the fork cannot be repaired by the dealer, and must be replaced.

If no gap is present (or if the gap is of an acceptable distance), BMW dealers must still press in a sleeve on the fork, before returning the bike back to the owner. With over 150,000 motorcycles potentially affected worldwide, this recall will be a massive undertaking for BMW Motorrad.

Owners for 2016 and 2017 model year KTM 690 Duke motorcycles should take note, as the National Highway Traffic Safety Administration (NHTSA) has issued a recall on the popular hooligan machine because it may leak fuel from its filler cap on the fuel tank.

The recall affects 718 units in the United States, but in documents to NHTSA, KTM says at this time it does not have a remedy for the problem, and that such a remedy could take up to 120 days to create.

Presumably, this would then bar KTM from selling any 690 Duke models in the United States until a fix can be made.

Water-cooled BMW R1200GS owners will soon be getting a call from their local dealership, as the popular adventure-touring machine is getting a worldwide service bulletin that affects models made between November 2013 and June 2017.

The service bulletin concerns the fixed fork tubes on the BMW R1200GS and BMW R1200 GS Adventure models, which can suffer damage from high stress incidents (going over an obstacle, riding through a pothole, etc), and subsequently fail.

By our math, this service bulletin affects over 150,000 motorcycles, making it a massive global undertaking for the German motorcycle brand, for its flagship model.

Piaggio Groups Americas is five Moto Guzzi models for issues relating to the brake hoses on their anti-locking brake systems.

According to documents filed with the National Highway Traffic Safety Administration, the issue stems from the brake lines rubbing against the engine’s secondary air system connect, which can result in a brake fluid leak.

The recall affects 1,139 units total of the 2016-2017 model year Moto Guzzi V7 III Racer 750, Moto Guzzi V7 III Stone 750, Moto Guzzi V7 III Special 750, Moto Guzzi V9 Bobber, and Moto Guzzi V9 Roamer motorcycles.

Conventional wisdom says that mixing wine with motorcycles is a bad idea, but in the case of last week’s 4th annual Kurt Caselli Foundation fundraiser at Doffo Winery in Temecula, California, it was a perfect pairing.

Kurt Caselli was an accomplished off-road racer with multiple AMA District 37 championships, Hare and Hound titles, and was the overall class champion in the International Six Day Enduro in 2007 and 2011.

Additionally, he was a competitor in the Dakar Rally and the Baja 1000. The Baja 1000 was where he met his untimely death in 2013, and after his death, the Kurt Caselli Foundation was formed.

The foundation was established to promote safety for off-road riders and racers, and strives to support these riders before, during, and after a racing career.

Are Michelin deciding the 2017 MotoGP championship? That would be an easy conclusion to draw after the war of attrition which the Gran Premi de Catalunya at Barcelona turned into. It would also be inaccurate.

This race, like the race at Jerez, was about managing tires in poor grip conditions, with the added complication in Barcelona of extremely high tire wear. The riders and bikes which managed that best ended up at the top of the results sheet. The bikes and riders which struggled with that went backwards, and lost out.

And yet Michelin undeniably has a role in all this. After the race, Honda boss Livio Suppo pointed out that we were seeing different manufacturers do well at each different race.

The pendulum swings between one and another, as a particular team or a particular factory hits the performance sweet spot for the tires, and gets the most out of them. At the next race, it’s a different rider, a different bike, a different team.

The criticism Suppo had was that the sweet spot for the tires could be hard to find. “The tires seem to have a very narrow operating window. If you get it right, you can be competitive,” he told me.

If you didn’t get it right, if you couldn’t find that operating window, you are in deep trouble. “Maybe it would be better if that window was bigger.”

That may be true. When Bridgestone were official tire supplier to MotoGP, their tires had a much wider operating window. But that tended to reward the teams with the biggest budgets to spend the most time analyzing data, finding the perfect setup, and the riders who could ride with inch-perfect precision for 25 laps.

That left little room for improvisation, for adapting to circumstances, for the element of surprise. Whether you prefer the Bridgestone way, rewarding relentless precision, or the Michelin way, rewarding the ability to adapt quickly, is probably a factor of where you as a fan fall on the Motorcycle Racing Purist Scale.

However you feel about it, though, the racing in the Michelin era is undeniably more entertaining.

Sunday at Barcelona is going to be a war of attrition. Everything is conspiring against the riders, and most especially the tires.

Temperatures are expected to rise even higher than they were on Saturday, when air temperatures hit over 32°C, and track temperatures climbed to 55°C and above.

Those are punishing temperatures in which to race a MotoGP bike, especially at Montmelo, where the heat gets trapped in the bowl of hills which holds the circuit.

Then there’s the tires. There is much complaining about the lack of grip and the fact that grip drops off a cliff after seven or eight laps.

It would be more accurate to blame that on the track, though: the Circuit de Barcelona-Catalunya has not been resurfaced in twelve or thirteen years, and is very heavily used, both by bikes and by cars.

That has created a surface which is both too smooth to provide grip, while simultaneously being incredibly abrasive.

That sounds contradictory, so when Michelin boss Nicolas Goubert spoke to a group of journalists on Friday night, I asked him to explain. The Frenchman explained that grip and abrasiveness came from two different parts of the surface.

Asphalt (or rather, a road or racing surface) consists two parts: binder and aggregate. Aggregate is basically small stones, specially selected for size and shape. Binder is usually a special formulation of bitumen, often containing other ingredients.

There are a lot of reasons to visit Barcelona. It is one of the greatest cities in the world, a triumph of the architectural movement known as Modernisme, a vibrant center of culture, a place where you can eat, drink, and sleep well, after a day spent gazing mouth agape at some of the most remarkable buildings created by human hands, and human minds.

Once upon a time, the Montmelo circuit was also a good reason to visit the city. A track full of fast, sweeping corners challenging riders and bikes in equal measure.

That was before the aging asphalt turned the track greasy in the summer heat, and the repeated abuse from fat F1 tires left the surface rippled and bumpy, cracked and patched.

Tragedy struck with the death of Luis Salom – probably the victim of a wayward bump sending him flying towards a patch of gravel-free run off – and the Safety Commission (consisting of MotoGP riders, Dorna, and the FIM) decided to neuter the second half of the track, removing one of the fastest and most furious final sections on the calendar. There is little left to love about Montmelo.

I asked several riders whether it would be possible to race in Montmelo next year if the track had not been resurfaced. The response was unanimous. “No.”

Worse than that, Bradley Smith explained how the Safety Commission had grown impatient with the circuit, which has been singularly unresponsive to their requests to adapt the track to make it safer. Hopefully, MotoGP would not return, Smith told us bluntly.

“That’s finally what it comes down to. This is the only track on the calendar that’s not actually reacting to Safety Commission / rider / organizer’s requests. So at some point, you have to give them an ultimatum, and I think that this is the last year that they’ll be in that situation. We have enough people that want us to go race there, we don’t have to come here.”

Last year, at Jerez or thereabouts, I had a chat with Livio Suppo about the insanely early start to MotoGP’s Silly Season that year.

Suppo bemoaned the fact that so many riders were switching factories so early, with contracts signed as early as Qatar (in the case of Bradley Smith and Valentino Rossi), and the ensuing hullabaloo surrounding Jorge Lorenzo, and whence he was bound.

“Normally, we start talking after a few races, in Mugello or so,” Suppo said. “You want a few races to see how strong a rider is.”

While last year’s Silly Season was nearing its close at Mugello last year, it seems that 2017 is taking a slightly more normal trajectory. This year, Mugello may have seen the early conversations, which kick off the period where riders discuss their future options.

And Barcelona was the first race where they started to discuss – or more accurately, hint at – those options publicly.

Why is this year’s Silly Season so much later (or so much more normal) than last year’s? Put simply, it’s because last year, every single factory rider was out of contract, and every factory seat was up for grabs.

This year, all the factory seats are still taken for 2018 (or at least, unless a factory boss decides that one of their riders is grossly underperforming), and there are only the satellite bikes at stake.

Fewer seats are available, and those which are available have less money attached, and less chance of competing for podiums and victories. All that combined leads to a lower sense of urgency when it comes to negotiations.

From Mugello to Barcelona, with, in most cases, nary a chance in between to head home and wash your smalls. It used to be that the trip from Mugello to Barcelona was a chance to see MotoGP race back-to-back at two of the great motorcycle racing circuits.

Now, it’s one and a half great circuits, with a nadgery little section tagged on at the end to slow everything down. Or as Marc Márquez described it in Mugello, “You arrive [at Montmelo] and you know that it’s kind of two different tracks: the first part is really fast and wide, the last part tight and slow.”

What was a temporary fix to solve the immediate issues exposed by the tragic death of Luis Salom last year – one year on, the paddock will doubtless be full of memorials to the bright young Spaniard – has been turned into a rather horrible bodge job.

The fast sweeper of Turn 12, where Salom fell and found himself on an unexpected trajectory across asphalt, and not gravel which would have slowed him down, is replaced by an even tighter and shorter chicane than last year, made so because of the proximity of the walls on the inside of the F1 chicane used last year.

It is a tragedy – I use that word advisedly, as it cannot compare with the loss of a young man’s life – to sacrifice one of the great sections of a motorcycling track.

But it is also an inevitable consequence of Grand Prix motorcycles getting ever faster, being able to brake later, carry more corner speed. The progress in motorcycle development is pushing their performance beyond the capacity of race tracks to safely host that performance.

Dunlop Sportmax Q3+ tire owners have some worry today, as Sumitomo Rubber USA (the maker of Dunlop motorcycle tires) has issued a recall on its popular sport bike tire because of air pockets that may have formed during the tires’ curing process.

Sumitomo says that it has contained most of the affected 120/70ZR17 58W Sportmax Q3+ tires, which were made between April 27th and May 4th of this year, and that only four to seven tires need to be recalled from the consumer market.

Accordingly, Sumitomo will notify potentially affected Dunlop retailers and customers, and Sumitomo will offer replacement tires free of charge. The recall is expected to begin during June 2017. Concerned owners may contact Dunlop Motorcycle Tires at 1-800-845-8378.

After the jump, there is a timeline from Sumitomo on its discovery and quarantine process for the Dunlop Sportmax Q3+ tires. It makes for an interesting read regarding the internal QA process at the Dunlop tire facility.
