David Yurman Forged Carbon Moto by Walt Siegl

Many of you have likely seen Walt Siegl’s “Bol D’Or” custom MV Agusta Brutale 800 with a retro-flare. It is an amazing piece of work, and the basis for today’s post, which brings you a glimpse of the David Yurman Forged Carbon Moto by Walt Siegl. Actually the first model from Walt Siegl’s Bol B’Or line, we are just seeing this motorcycle now because it comes with a twist: it has forged carbon parts, crafted by jewelry maker David Yurman. A lot can be said about forged carbon, enough worthy of its own article, but the tl;dr version is that the composite material is set to replace traditional carbon fiber parts – in a big way. When you add that to an already attractive motorcycle design, well…checkout the hi-res photos yourself.

Skully Investors Oust Founders, Marcus & Mitch Weller

TechCrunch is reporting, and our sources have confirmed, that the investors behind the Skully AR-1 helmet have ousted one of the company’s founders, Marcus Weller, along with his brother Mitch Weller. For those who don’t know, Marcus Weller was Skully’s CEO, while Mitch Weller served as the company’s Chief of Staff. The departure of the Weller brothers comes after Skully continually missed its delivery deadlines with its first product, the Skully AR-1, which is a helmet with an integrated rear-facing camera, small computer system, and heads-up-display oculus. Hopefully this means that Skully will finally get on the right path and begin delivery helmets to its plethora of early backers. We are not holding our breath, however.

2017 Montesa Cota 4RT260 Gets “BNG” – Still Awesome

Normally, we would roast a brand for bringing a “bold new graphics” model to market, but in the case of the 2017 Montesa Cota 4RT260, we will give the Spanish firm a pass…purely because we think trials riding is AWESOME. So, yup…for the 2017 model year, Montessa is brining basically the same machine to market, with the big changes being the red, white, and blue HRC-inspired color scheme, along with the chromed fork tubes that have black-painted lowers. If it counts as a technical change, the kickstarter lever has been made longer than on what is found on the 2016 model, and of course there is a “race replica” version, which drips in carbon fiber, Showa suspension pieces, and has the traditional Repsol livery.

Bottpower BOTT XR1R – The Street Tracker You Deserve

The Bottpower BOTT XR1R is the bike that Harley-Davidson should be building right now, and it’s the kind of machine that actually would have benefitted from Buell’s “innovations” for street bikes. With 150hp and a target weight of 150kg, the BOTT XR1R should be plenty of fun on tight circuits, but still powerful enough for longer courses. And then of course, once you’re done flogging the XR1R for the day, you will still want to spend a couple hours drooling over its titanium frame, carbon fiber bodyworks, and modern-day electronics. We have always been a fan of Bottpower’s work, but it still feels strange to say that the Spanish builder has created the bike that America has been dreaming of for the past decade or more.

Ducati 1299 Panigale S Anniversario – Celebrating 90 Years

Ducati is celebrating its 90th anniversary this year, with the culmination of that celebration happening at World Ducati Week. As we previewed already, Ducati would give a sneak peak of a new model at the event, and debut a limited edition machine as well. Well, we have had more than a sneak peak of the upcoming Ducati Supersport model, and now we get the full monty of the Ducati 1299 Panigale S Anniversario – a special superbike that commemorates 90 years of Ducati motorcycles. Only 500 machines will get the Ducati 1299 Panigale S Anniversario’s limited edition paint job, gold-colored metal pieces, and bevy of technical upgrades. One interesting new feature though is the debut of the EVO version of the Ducati Traction Control (DTC) and Ducati Wheelie Control (DWC) systems.

Some Details on the New Ducati Supersport

You may have already seen the leaked photo from World Ducati Week, which shows that the Ducati Supersport is making a return to Bologna’s lineup. We haven’t seen the “Supersport” sport-touring line in almost a decade, but it will be making a return for the 2017 model year, with two bikes. Since yours truly is at World Ducati Week this year, I was able to get a peak at the Supersport, and can share with you some details on the machine. The Ducati Supersport has a rich history as a sport-tourer; back when that segment actually existed, and was distinct from being just a superbike for the road. This model seems very much a return to that past.

Ducati SuperSport S Spotted at World Ducati Week

Of the many attractions at the Misano World Circuit Marco Simoncelli, Ducati is giving enthusiasts a chance to preview a new bike that will officially debut at the EICMA show in Milan (in addition to the two machines that will unveil tomorrow). The affair is a strictly managed, no cellphones allowed, sort of sneak peak at the new machine – thus, it comes as no surprise that some fan has snapped a photo of the secret bike on a hidden phone. In case you were wondering, this is why we can’t have nice things. You can’t put the cat back in the bag though, so get ready folks because we have good news: the Ducati SuperSport is coming back! As you can see in the photo, the machine in question is called the Ducati Supersport S, an homage to the bikes of the same name that came almost 40 years before it.

The Bullshit Argument That It’s Time to Say Goodbye to the Honda CBR600RR and Other Supersport Machines

British magazines MCN dropped a bombshell on the motorcycle world today, reporting that Honda was set to discontinue the Honda CBR600RR, with no supersport replacement in sight. According to their reports, the main impetus for the Honda CBR600RR being discontinued is the Euro 4 emission standards, which the Honda CBR600RR does not meet. Honda feels too that the demand for a 600cc sport bike is too low to warrant updating the CBR600RR to meet Euro 4 regulations, let alone building an all-new machine for the market that would be Euro 4 compliant.

KTM Is Working on an 800cc Parallel-Twin ADV Bike

“If your quarry goes to ground, leave no ground to go to” seems to be KTM’s marching orders right now, as the Austrian brand is pushing into seemingly every segment and market with its motorcycle lineup. KTM already has a robust off-road lineup, which they have used to launch themselves into the ADV category with great success. As such, the KTM 1190 Adventure series already sees strong sales success with adventure-touring riders, but KTM isn’t resting on those laurels. Set to debut a 800cc parallel-twin platform later this year, KTM CEO Stefan Pierer has revealed, while talking to MCN, that his company will soon have a rival for the Honda Africa Twin.

XTR Pepo’s “Siluro” Custom Ducati Monster 1200

It has been a while since we showed you one of XTR Pepo’s custom works, so please forgive our sins. To make it up to you though, we have the Siluro, a custom Ducati Monster 1200 that Ducati Spain commissioned from the Spanish bike builder. If I’m honest, Ducati’s Monster line has really never struck a chord with me, but there is something about the Siluro that’s got me more than a little twitterpated. Perhaps it is the high-mount, scrambler-styled Termignoni exhaust, or maybe it is Pepo’s signature “RAD” seat, that has adorned so many custom Ducati’s before this one, but is now wrapped in suede. Whatever it is, it’s working.

Over-Revving Caused Yamaha’s Mugello Engine Woes

06/02/2016 @ 1:58 pm, by David Emmett19 COMMENTS

MotoGP-2016-Mugello-Rnd-06-Tony-Goldsmith-3396

Yamaha have issued an official explanation for the problem they suffered at Mugello, which saw Valentino Rossi’s engine blow up during the race, and Jorge Lorenzo’s engine blow up during warm-up on Sunday morning.

The cause given is exactly in line with the reasoning in our Mugello Sunday post-race round up: the engine overrevving as the rear wheel lifted at the end of the Mugello straight.

At that point in the track, with the bike hitting 350 km/h and nearing peak speed at top gear and at full throttle, when the rear wheel lifts over the crest at the end of the straight, the engine spins up too quickly for the rev limiter to catch.

MotoGP Tech Director: No Breach of Moto3 Rev Limit Found

Honda-NSF25RW-engine

MotoGP’s Technical Director has rejected KTM’s claim that Honda exceeded the official Moto3 rev limit during the 2015 season.

In an official statement issued today, Danny Aldridge said that he and his technical team had examined the official rev limiter used in Moto3 and verified that it was operating correctly, and that although there had been overshoots of the rev limit, these were very small and very brief.

Aldridge went on to confirm much of what we had found when we investigated the issue at the end of February. Speaking to Peter Bom, crew chief of 2015 Moto3 world champion on a Honda Danny Kent, Bom explained that the issue had been about the way in which Honda had optimized the point at which the rev limiter cut in, and this is what had caused the confusion.

KTM Claims Honda Exceeded Moto3 Rev Limit

KTM-Moto3-motor

Were Honda exceeding the Moto3 rev limit in 2015? This is the accusation made by KTM Sports Director Pit Beirer in a story on the German-language website Speedweek.

Beirer alleges that KTM came across the issue when talking to riders who switched from Honda to KTM this year, who were complaining of how abruptly the KTM hit the rev limiter.

Beirer further claims that KTM were able to look at the data of the Honda Moto3 machine held by a former Honda mechanic. In that data, he alleges, the Honda ran flat out to the 13,500 RPM rev limit, then gradually tailed off to 13,600 RPM.

These claims, if they are true, would be a massive breach of the Moto3 regulations. Though Beirer does not mention Danny Kent by name, the insinuation was that this may have been a factor in a Moto3 title that ended up being decided by just six points.

We spoke to Peter Bom, crew chief to Danny Kent both this year and last, during his successful Moto3 championship campaign, and a key factor in the Englishman’s title. Bom denied the allegations, and explained that the claims can only be based on Beirer misinterpreting the facts.

The difference between the Honda and KTM Moto3 rev limiter strategies was marked, Honda having invested a large amount of time and money in optimizing both gear change and rev limiter strategies, making the bike as smooth as possible and as easy to ride.

Minimum Weights To Be Reduced Soon in MotoGP

The news that 340mm carbon brake discs are to be allowed once again in MotoGP has rekindled a debate that has been going on behind the scenes for some time.

The move to allow the discs at all tracks, and not just Motegi where they are already compulsory, has come as both power and weight of the MotoGP machines has grown over the past three years. But the real solution lies in reducing the minimum weight.

There was a certain irony in the moment chosen by the Grand Prix Commission to ban carbon discs larger than 320mm. The move – made for reason of cost savings and rationalization – came just as MotoGP was to return to 1000cc, meaning the bikes were about to reach higher top speeds.

Compounding the problem, the minimum weight was also increased. The initial proposal was to raise the minimum from 150kg, the weight of the old 800cc machines, to 153kg. However, to make life easier for the CRT machines, the weight limit was raised even further, in two steps, to 157kg in 2012 and 160kg in 2013.

In the space of two years, engine capacity had been increased by 25%, leading to a power increase of around 10%, while weight had also been increased by nearly 7%. It was a recipe for brake problems, and that is precisely what occurred.

Factory 2 Rules Adopted for 2014 Season: Spec-Software Compulsory in MotoGP from 2016 Onwards

03/18/2014 @ 8:16 am, by David Emmett34 COMMENTS

motogp-logo

After a week of debate and discussion, the Grand Prix Commission has finally reached an agreement on the Factory 2 class. It took many hours of phone calls, and full agreement was not reached until late on Monday afternoon, but the agreement contains some significant changes to the long-term future of the MotoGP championship.

The Factory 2 proposal has been adopted in a slightly modified guise, with any manufacturer entering in the Open class liable to lose fuel and soft tires should they win races. But the bigger news is that the full MotoGP class will switch to use the spec software and ECU from the 2016 season, a year earlier than expected.

The proposals adopted by the GPC now lays out a plan for MotoGP moving forward to 2016. In 2014 and 2015, there will be only two categories – Open and Factory Option – with the set of rules agreed at the end of last year.

The new proposal sees manufacturers without a dry weather win in three years to compete as Factory Option entries, but with all of the advantages of the Open class – more fuel, more tires, no engine freeze and unlimited testing. However, should they start to achieve success, they will start to lose first fuel, and then the soft tires.

If Ducati – for it is mainly Ducati to which these rules apply, as they are currently the only manufacturer who are eligible at the moment – score 1 win, 2 second place finishes or 3 third places during dry races, then all bikes entered by Ducati will have their fuel cut from 24 to 22 liters for each race.

Should Ducati win 3 races in the dry, they will also lose use of the softer rear tires which the Open category entries can use. If Ducati were to lose the extra fuel or tires during 2014, they would also have to race under the same conditions in 2015.

Official: MotoGP Drops Rookie Rule & Single-Bike Rule – But Restrictions On Factory Bikes Introduced

07/02/2012 @ 5:08 pm, by David Emmett9 COMMENTS

Much was expected of this Friday’s meeting of the Grand Prix Commission, but in the end, the decisions taken were relatively minor. Dorna, IRTA, the FIM, and the MSMA agreed on a number of proposals which had widely been expected, but made no real progress on the major rule changes expected for the 2014 or 2015 season.

The rule change with the biggest immediate impact was the dropping of the Rookie Rule, as we reported during the Silverstone round of MotoGP. The dropping of the Rookie Rule, which prevents new entries into the MotoGP class from going straight to a factory team, opens the way for Marc Marquez to join the factory Repsol Honda team next season. Contrary to popular opinion, however, the rule was not dropped at the request of HRC, but rather of the Honda satellite teams themselves, both Lucio Cecchinello and Fausto Gresini fearing the disruption that Marquez would bring for just a single year.

No MotoGP Rev Limit Until 2014

05/01/2012 @ 3:03 pm, by David Emmett6 COMMENTS

Jerez saw another round in the game of bluff poker being played between Dorna and the manufacturers over the future of MotoGP’s rules, and both sides took another step closer to an agreement. Reports emanating from the discussions suggest that Dorna has made a concession to the MSMA over the rev limits, while the factories are pushing through a single-bike rule, and an agreement should be ready by the middle of the year.

Ever since the MSMA lost their monopoly over the rules at the end of 2011, when the contract between the MSMA and Dorna lapsed, Dorna has had the stronger hand, and Carmelo Ezpeleta has been pushing the factories hard for changes. The pressure is starting to pay off for Ezpeleta, as by a combination of cajoling, threats and promises, he has also reached an agreement over the future shape of the sport. MotoGP is to undergo a radical transformation from the pure technology exercise that was the 800cc era, and become a sport focused on entertainment, where costs are kept in check.

Official: 2011 Kawasaki ZX-10R Gets 750 RPM Redline Reduction Because of EPA Noise Laws

10/08/2010 @ 3:58 pm, by Jensen Beeler14 COMMENTS

We just got off the phone with Kawasaki HQ, and it’s official: the 2011 Kawasaki ZX-10R will inadvertently get a power decrease when it comes to the United States because of the EPA’s regulation of noise pollution, confirming earlier rumors from this week. The issue surrounds the EPA’s new methodology for measuring exhaust noise levels, which now involves taking the measurement at a percentage of the total rev range, instead of a specific rpm value.

The result is that the 2011 Kawasaki ZX-10R passes the Euro III standards, but fails the EPA standards in its unadulterated form. To come into compliance with the EPA’s Noise Control Act, Kawasaki has lowered the rev-limit on the 2011 Kawasaki ZX-10R by 750 rpm in order to meet the new criteria. The byproduct of lowering the rev-limiter will reduce the new ZX-10R’s maximum power output, but Kawasaki isn’t saying by how much.
