Yes, Winter Traction Tires Exist for Motorcycles

If you are in a region that gets all four of the seasons, you are likely counting down the days to the coming snow-thaw. As such, this article might be coming to you a little late for this season, but for next winter you should consider mounting some winter traction tires to your motorcycle. Yes, such things exist. To be fair, I too was unaware that you could get a motorcycle tire that met the criteria from the DOT, in order for it to carry the “mountain/snowflake” symbol, but apparently Turkish tire-maker Anlas has such tires in its line-up. That’s right, for regions of the world that require special tires during the snowy months, there is a tire out there to keep you riding all-season.

SWM Motorcycles Targets 6,000 Units in 2017

You probably haven’t heard of SWM Motorcycles, the off-road brand that carries on where Husqvarna left off in Italy. Built from the parts that KTM didn’t want when it bought the Swedish brand in 2013, SWM Motorcycles is based outside of Milan, Italy and produces a variety of off-road focused machines using pre-BMW Husqvarna engine designs. Many members of the company’s team are former Husqvarna employees, including the company’s CEO, Ampelio Macchi – all of whom were left out in the cold when the German brand sold Husqvarna to KTM. But, with a new production facility, support from the local government and worker unions, along with Chinese financing (from the Shineray Group), SWM Motorcycles has taken on a new life with a promising future.

How Dorna Is Ending the Spanish Armada in MotoGP

It is terribly fashionable in some circles to regard Dorna as a blight on the face of motorcycle racing. Their alleged crimes are both heinous and manifold. They have dumbed down the sport by exerting an ever tighter grip over the technical regulations. They killed off the two-strokes in favor of four-strokes. They have aggressively pursued copyright and trademark claims, at the cost of broadening the appeal of the sport. They have been relentless in their pursuit of financial gain over the spirit of the sport. They have meddled in the sport to favor one rider, or one nationality over the rest. Most of these complaints are either baseless, or an expression of anger at how the sport has changed over the years.

The 2017 Aprilia RS-GP MotoGP Race Bike Debuts

The final factory MotoGP to debut its 2017 MotoGP Championship race bike, Aprilia has finally debuted the 2017 Aprilia RS-GP that Aleix Espargaro and Sam Lowes will campaign this year. The Italian outfit continues to make quiet strides in its development with the RS-GP, though the efforts from Suzuki and KTM tend to dominate the headlines. For the 2017 season, Aprilia looks ready to take another step forward, especially with Aleix Espargaro at the helm. The biggest task for the 2017 will be to bring more horsepower to the Aprilia RS-GP. The machine reportedly handles quite well, though that is often an item of praise that changes as the power increases.

The Subtle Big Deal That Is Ducati Premier Financing

Ducati released a new financing program this week, maybe you saw the announcement already. If you even bothered to read one of the copy/paste jobs on this announcement, you probably got three sentences into it, and then realized you just lost a minute or two of your life, which you will never get back. It is hard to make this topic sexy, and motorcycle journalists are lazy creatures (myself included)…which is why you probably just saw the press release reprinted on a website, with some Ducati advertising placed next to it, just for good measure. The Ducati Premier Financing program is a big deal though, just not in a way that is immediately sexy to the casual motorcycle buyer.

Washington Lane-Splitting Bill Passes State Senate

Legalizing lane-splitting in Washington State just got a step closer to reality, as the State Senate of the Washington State Legislature has passed a bill that would allow lane-splitting under very specific circumstances. Senate Bill 5378 (SB 5378) would allow lane-splitting only during slow traffic conditions – up to 10mph faster than the flow of traffic, but no faster than 25 mph – and only on numbered highways that have a median and multiple lanes of traffic in each direction. The bill passed the senate with 32 “yea” votes from both Republicans and Democrats, while the 17 “nay” votes came solely from Democrat members.

Indian Working on an Electric Motorcycle?

Polaris Industries says it is working on a new electric motorcycle, to replace the now discontinued Victory Empulse TT model that was scrapped when the Minnesota company closed the doors to the Victory brand earlier this year. According to a report from Reuters, the new electric motorcycle will be released under the Indian Motorcycle brand name, and will be focused towards riders who ride for pleasure, rather than those who commute or do long-distance trips. The report says that Polaris is targeting a 120 to 140 mile range – almost double of what was available from the Empulse TT – from this new electric motorcycle model, when ridden at an aggressive pace.

Indian’s Flat Track Racer Now Available to Mere Mortals

When the Indian Scout FTR750 flat track race bike debuted, our comments section was filled with enthusiasts screaming for a production version of the water-cooled 750cc machine. Well my friends, your prayers have been answered…in part. Indian is making the Scout FTR750 available to anyone who has the coin to spend, with a couple caveats: 1) you will need to pony up $50,000 in order to purchas the bike, and 2) it will be a race-only model. Still, the news should be exciting for privateer flat track racers who are keen to use Indian’s very trick racing package, which looks to be far more purpose-built than Harley-Davidson’s Street 750 based offering.

Report Says Sport Bike Sales in USA Dropped 4.7%

The data continues to support the notion that sport bike sales are contracting, with Powersports Business releasing a report that sport bike sales dropped by 4.7% over a 12-month period that ended in October 2016. According to the dataset put together by Statistical Surveys Inc., 75,469 sport bikes were registered in the United States during last year’s time period, compared to the 79,225 motorcycles that were registered the previous year. While the general trend across the country is a drop in sport bike sales, the research also showed some interesting locations where sport bike sales actually increased dramatically, showing that there may be a location element to the demise of the sport bike.

A Honda RVF1000 V4 Superbike for 2019?

Since before I started Asphalt & Rubber, the scribe’s at MCN have been predicting a MotoGP-derived V4 superbike from Honda – I think the original rumor started with a V5 power plant, if that gives you an idea of how long this story has been making the circuit. The hands on the clock are finally starting to meet with reality though, and the British magazine now says that a more affordable version of the Honda RC213V-S could hit dealerships in time for the 2019 model year. This information echoes similar news that we saw before the launch of the updated Honda CBR1000RR – that Honda was working in parallel on a new Fireblade as well as a V4 superbike project. Though now, MCN now points to recent patents filed by Honda, as well as sourced information that the bike is a couple model years away.

What We Learned from the Ducati MotoGP Launch

01/23/2017 @ 10:19 am, by David Emmett6 COMMENTS

From one presentation to another. Having the Movistar Yamaha and Ducati Factory team launches on consecutive days made it a little too easy to make comparisons between the two.

There was much complaining on social media about the fact that large parts of the Yamaha presentation were in Spanish only, causing the international audience watching the live streaming to lose interest.

Ducati’s approach was better: while everything in the presentation was in Italian, there was simultaneous translation available on the live stream, so those following could hear it in English.

That was no good to us in the hall, of course, though we would find out later that there had been headsets available with the live translation available. But nobody had thought to tell us about that, of course.

Still, we got to practice our racing Italian, a necessity (along with racing Spanish) for those who work in MotoGP.

There was not much to complain about the location. Just as last year, the launch took place at the Ducati factory in Borgo Panigale, just west of Bologna.

The auditorium is not much to write home about – a dark room with a stage – but journalists and guests were welcomed in the Ducati museum, a glorious place filled with Ducati history and a lot of racing past. If you are heading to Mugello or Misano, a visit to the museum is highly recommended.

Here’s a Sneak Peek of the KTM RC16’s V4 Engine

10/26/2016 @ 8:39 pm, by David Emmett41 COMMENTS

KTM-RC16-MotoGP-Test-Mugello-Tom-Luthi-15

With the KTM RC16 MotoGP bike nearing its very first race, as a wildcard at Valencia, the Austrian motorcycle manufacturer is starting to preview that first appearance.

They are doing so through a series of videos, which they are sharing on their YouTube channel and via their Social Media channels. The videos include interview fragments with the team behind the bike, as well as footage of the machine.

The video is remarkably revealing. The engine layout is clearly shown, as is the 90° V4 engine, though this was no secret. The video also shows the engine performing a simulation of Mugello, which gives a good idea of what the bike sounds like.

The engine being tested on the dyno sounds remarkably similar to Honda’s V4 RC213V engine, which uses a “screamer” firing interval, each cylinder firing separately.

The New Harley-Davidson Milwaukee-Eight Engine Debuts

08/25/2016 @ 1:00 pm, by Jensen Beeler12 COMMENTS

Harley-Davidson-Milwaukee-Eight-engine

What you are looking at above is Harley-Davidson’s ninth iteration of its “Big Twin” engines. It’s called the Milwaukee-Eight, named after Harley-Davidson’s home town and the fact that the engine head design employs a very modern eight valves in total (four per cylinder head).

Time will tell if the Milwaukee-Eight becomes as iconic as Harley-Davidson’s other designs, like the Flathead, Knucklehead, Panhead, etc. But, we do know that the Milwaukee-Eight marks a more modern approach to engine design from the Bar & Shield brand.

To this end, Harley-Davidson says that the new power plant offers a quicker throttle response, more passing power, purer sound (whatever that means), and a smoother ride (read: less vibrations).

The Milwaukee-Eight will first be used on Harley-Davidson’s touring and trike lines, though we can expect the engine design to permeate through Harley-Davidson’s lineup.

Two Enthusiasts Podcast #28 – Getting Cranky

08/15/2016 @ 7:58 pm, by Jensen Beeler12 COMMENTS

two-enthusiasts-podcast

Episode 28 of the Two Enthusiasts Podcast starts with some recent news: the closure of Skully and the near-passage of California’s lane-splitting law.

The conversation about Skully quickly moves from the failed startup, to a broader conversation about helmet design and the progress of technology in this space. The show then turns to California’s lane-splitting law, and what it could mean for motorcyclists in states other than California.

Once the news items are out of the way, the show spends a bit of time talking about crankshaft design, namely what it means to have a “crossplane” crankshaft.

Further down the rabbit hole, this turns into a larger conversation about how engines make their power, and how that power is tuned for specific tasks. It’s a tough subject to do only via voice, but we think you’ll enjoy it.

As always, you can listen to the show via the embedded SoundCloud player, after the jump, or you can find the show on iTunes (please leave a review) or this RSS feed. Be sure to follow us on Facebook and Twitter as well. Enjoy the show!

Indian Motorcycle Returns to Flat Track Racing

06/14/2016 @ 12:51 pm, by Jensen Beeler18 COMMENTS

Indian-Motorcycle-Scout-FTR-flat-track-racing-Jared-Mees-02

AMA Pro Flat Track is heating up. First, it was Harley-Davidson announcing its first flat track race bike in 44 years, the Harley-Davidson XG750R. And now, we get word that Indian Motorcycle is set to compete as well, debuting today a purpose-built v-twin engine for the job.

The Indian Scout FTR v-twin engine is a 750cc liquid-cooled four-valve lump that is specifically designed for flat track racing. Using a specially built chassis, Indian aims to compete in AMA Pro Flat Track, with Jared Mees serving for now as the company’s test rider.

Indian says it will compete at a single 2016 event, which is still to be announced, before going after the 2017 AMA Pro Flat Track title in full. Presumably Mees will headline that effort as well, which if the case, should make Indian’s entry a very potent one.

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.

April Fools: Honda Patents Three-Stroke Engine Design

04/01/2016 @ 8:16 am, by Jensen Beeler19 COMMENTS

honda-three-stroke-engine

Fresh from the office of the USPTO, we have confirmation that Honda has just received the patent for the first ever three-stroke motorcycle engine.

As you would expect, the unconventional engine design incorporates the power-to-displacement efficiencies of a two-stroke smoker, with fuel-to-power efficiencies of a four-stroke motor.

For many in the space, the three-stroke engine has been the Holy Grail of engine designs, with many OEMs rumored to have been working on a three-stroke engine.

Still, it is surprising to see the engineers at Honda claim the prize, as the Japanese brand up until recently has been heavily committed to its four-stroke technology.

Obviously, the engine technology can obviously be applied to any internal combustion application, however what makes this news especially A&R worthy is that Honda’s patent specifically states the engine’s purpose in two-wheeled vehicles, watercraft, lawnmowers, and generators.

KTM Drops Hint of “Revolutionary” New Engine Platform

03/31/2016 @ 2:20 pm, by Jensen Beeler24 COMMENTS

KTM-800-Duke-spy-photos-02

Aside from Husqvarna bringing the Vitpilen & Svartpilen concepts into production, another gem to come from KTM’s investor report for 2015 is that the Austrian company is working on what it calls a revolutionary two-cylinder engine design.

KTM is surely referencing the parallel-twin project that has been spotted a few times by spy photographers (shown above, and featured after the jump), which is rumored to feature an 800cc lump.

We are not too sure what is so revolutionary about a parallel-twin power plant – my Two Enthusiasts Podcast co-host Quentin loves to go on rants about how much he hates the engine design – but what is interesting is to hear that KTM plans on using the engine as a platform for multiple models.

New MV Agusta Brutale 675 Coming in Q2 2016

01/25/2016 @ 11:52 pm, by Jensen Beeler11 COMMENTS

2016-MV-Agusta-Brutale-800-13

Confirmed at the launch of the 2016 MV Agusta Brutale 800 in Spain, MV Agusta will bring the smaller sibling to its three-cylinder Brutale line in the second quarter of 2016.

Like the new Brutale 800, we can expect the updated Brutale 675 to be fully Euro4 compliant. We would also expect the 675cc to have the same mechanical and styling changes that are found on its 800cc sibling, namely a revised chassis geometry, updated MVICS 2.0 electronics (traction control, ABS, & quickshifter), and visual changes to the headlight, exhaust, and body.

Is Honda Preparing a Major Engine Upgrade for 2016?

01/16/2016 @ 12:24 am, by David Emmett4 COMMENTS

Winter-Test-2016-Jerez-MotoGP-WSBK-2015-Tony-Goldsmith-0086

It is no secret that Honda are struggling with the engine for the RC213V MotoGP. HRC have been making the engine ever more aggressive for the past three years, but in 2015, they finally went too far.

The power delivery of the RC213V was too difficult to contain, even with Honda’s electronics, and HRC suffered their worst season in MotoGP since 2010.

Things had not been looking much better for 2016 either. The engine Dani Pedrosa and Marc Márquez tested at Valencia and Jerez last November was at best a marginal improvement, with a bit more power at the bottom end, but still delivered in a very aggressive manner.

Added to this, HRC have had problems with the new unified software which is compulsory for 2016. Where Ducati, and to a lesser extent Yamaha have managed to integrate the less complex spec software into their engines, Honda have yet to get a handle on it.

That has made assessing the engine character even more difficult for Pedrosa and Márquez, the Repsol Honda riders finding it hard to pinpoint aggressive and abrupt throttle response on the engine character, the cruder software, or the interaction between the two.

It is a problem that Honda is now acknowledging publicly. HRC boss Shuhei Nakamoto admitted to the Spanish sports daily Marca that they were having trouble making their engine less aggressive.
