New Triumph Street Triple Debuts with 765cc Engine

As expected, today we get to see the 2017 Triumph Street Triple, with its new engine capacity: 765cc. The new engine displacement comes from both an increase in bore and stroke on the iconic three-cylinder motor, with Triumph using a new crank, pistons, and barrels in its construction. Three flavors of Triumph Street Triple will be available for 2017, with S, R, and RS-spec (above) machines being available, with obvious performance differences existing between the trim levels. As such, peak horsepower will be 113hp (S), 118hp (R), and 123hp (RS) – a notable boost over the 675cc machine’s 105hp. Meanwhile, peak torque has been improved from 50 lbs•ft, now to 53 lbs•ft (S) and 56 lbs•ft (R & RS). All the models tip the scales at 166kg (dry) according to Triumph, which is a 2kg reduction over the outgoing model.

Victory Motorcycles Ceasing Operations

Polaris Industries is starting the year off with some surprising news, announcing that it will cease operation of Victory Motorcycles and other related business operations to the brand. Scott Wine, Polaris Industries Chairman and CEO, explained the decision as coming down to basic business factors, with Victory not showing the growth and volume in order to sustain its continued existence. Polaris in its press release also cites the changing landscape of the motorcycle landscape, and that the resources and investments required to make Victory competitive going forward were too hard to justify for the troubled brand. Instead, Polaris will focus solely on its Indian and Slingshot brands, for the motorcycle space.

Triumph Set to Become the Official Moto2 Engine Supplier

The future of the Moto2 class looks secure. Reports from the UK and Austria are suggesting that Triumph has finalized a deal to supply the Moto2 class when the current deal with Honda concludes at the end of 2018. From 2019, Triumph will supply a new three-cylinder engine, probably based on the new, larger sports triple they are building for release in 2017. There had been uncertainty over the future of the Moto2 engine supplier since the beginning of this year. Honda had extended the deal to supply CBR600RR engines until the end of the 2018 season, but as the Japanese manufacturer was stopping production of its middleweight sports bike, it was clear that a replacement would have to be found.

Walt Siegl’s Dakar Inspired Ducati Hypermotard

This Dakar Rally inspired Ducati Hypermotard is the latest creation from Walt Siegl Motorcycles, and it comes with some very appropriate timing. Not only are we full-swing into the 2017 Dakar Rally, but this 1980s-styled Ducati comes during a week where we have been talking about my not-so-secret love affair with the Ducati Hypermotard. Again, we see the air-cooled version of this street-going supermoto being used as a platform for a unique work, though this time Walt Siegl has been commissioned to make a bike that rolled right off the sand dunes of Africa. The exercise centers around mostly the restyling of the bodywork, to give us a little nostalgia for when the Dakar Rally was actually held in its namesake in Northern Africa.

Mike’s Carbon Fiber Motus MSTR

The Motus MSTR is a beast of a machine, it just oozes raw power and torque from its 1,650cc V4 engine; and to compliment all that grunt, the MSTR also comes tastefully wrapped in painted carbon fiber fairings. But when a composites expert wants one of your motorcycles, painting those carbon fiber body panels might not be the best of choices – it may even be an affront the Gods of Internal Combustion. When customer “Mike M.” wanted to see show off the weave of the Motus MSTR’s carbon fiber bodywork, he opted for his machine to come sans the livery. We think that was a pretty good choice, and the gods are surely pleased as well. So, to help get the New Year off to a proper start, and to return to the appreciation of all things two-wheeled, we give you Mike M.’s Motus MSTR motorcycle – how’s that for alliteration?

10 Things to Look Forward to in Motorcycle Racing for 2017

The new year has officially started, the real world of contracts finally lining up with the world of motorcycle racing. Riders who swapped factories are now free of their old contracts, their new contracts having commenced as the world greeted 2017. That also leaves them free to post about the new season on social media again. Aleix Espargaro was so keen to do so that he posted right on the stroke of midnight. If the riders are excited, that gives fans reason to be excited too. Here are 10 reasons to look forward to 2017.

Michael Lock Talks About the Future of Flat Track Racing

As discussed previously on Asphalt & Rubber, flat track racing in the United States will have a comprehensive makeover in 2017. The series will be rebranded as the American Flat Track Series, and the calendar expanded to 18 rounds. At the Superprestigio in Barcelona last weekend, the CEO of the American Flat Track series, Michael Lock, sat down with Asphalt & Rubber to discuss the reasoning behind the changes. The expat Englishman came to flat track with a unique perspective; that of an outsider. He was an Englishman abroad, and brought fresh eyes to the problem of trying to grow flat track racing once again. The single biggest change is to simplify the structure of the championship with the GNC1 class now just for twin-cylinder engined bikes, with the GNC2 class using the smaller singles.

XXX: 21 Hi-Res Shots of the Ducati 1299 Superleggera

Did Santa forget to put a certain carbon fiber superbike under the tree this Christmas? Us too. Since we aren’t one of the lucky 500 people who will be receiving the Ducati 1299 Superleggera in 2017, we will have to make do with appreciating Ducati’s latest halo bike from a distance. Ducati officially lists the 1299 Superleggera as making 215hp and weighing 156kg dry, though with the installation of the included race kit that peak horsepower figure pops to 220hp, while the dry weight drops to a near-nothing 150kg. There might be a lot of talk about the death of sport bikes, but we argue that they have never been more intriguing. You won’t find any photos of the Ducati 1299 Superleggera at a higher resolution than the ones after the jump. Enjoy!

No Money for New MV Agusta Superbike, Says Castiglioni

To call the last couple of years for MV Agusta turbulent would probably be understating the situation. The company has struggled for financial stability ever since its re-acquisition by the Castiglioni family, and that struggle has recently come to a zenith with the firms debt restructuring and investment by the Anglo-Russian investment group Black Ocean. With that comes some harsh realities, namely that MV Agusta will not be producing a new superbike any time soon, as the cost of the project exceeds the Italian manufacturer’s capabilities – so said MV Agusta CEO Giovanni Castiglioni while talking to Alan Cathcart for Australian Motorcycle News.Instead, the company will focus on a new four-cylinder Brutale model, which will get a displacement increase to 1,200cc.

The Top 10 World Superbike Riders of 2016

Top ten lists are by their very nature subjective; beauty is in the eye of the beholder after all. From the moment the season started in Australia until the very end there was a great scrap for the title, with the fight going down to the wire in Qatar. But, who was the best rider of 2016? This is the our Top 10 riders of the 2016 World Superbike season. It’s always easy to go with the champion for any Top 10 list, and while Chaz Davies would also have been a very deserving candidate, ultimately Rea’s title defense was superb. The Kawasaki rider was clearly not as comfortable with the 2016 bike as its predecessor, but Rea won nine races and was in constant control of the title fight. He did this by winning fewer races than Davies, leading fewer laps than Davies or Sykes, and having fewer pole positions.

Over-Revving Caused Yamaha’s Mugello Engine Woes

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.
