Battery “Thermal Events” Lead to Zero Recall & Buy-Back

Zero Motorcycles is reporting a very serious defect with its 2012 model year bikes, specifically affecting the Zero S, Zero DS, and Zero DSP (Police) models. The recall concerns Zero’s battery architecture for the 2012 model year, which may cause cells to fail, and thus create a runaway “thermal event” (read: catches on fire) within the battery pack. In total, this recall affects 218 motorcycle units – the entire volume of Zero S, Zero DS, and Zero DPS motorcycles that were sold for the 2012 model year. In its recall documents, Zero cites three instances (one in Hong Kong, and two in the USA) where the battery packs on the affected 2012 model bikes have failed and lead to a thermal event.

Benelli’s Grom-Killer Debuts for the US Market, A Review

For years, Benelli has lain dormant, at least in the US market. That changes with the Chinese owned, but Italian-run, firm releasing the first of many street bikes for American consumption. It kicks things off with the 2018 Benelli TnT 135 ($2,499). US importer, SSR Motorsports, hosted a quick day ride that began atop Southern California’s Ortega Highway, and concluded in Newport Beach. Renowned for its twists and turns, Ortega Highway is an amusing, but also very high-traveled ribbon of blacktop that links the bustling inland and beach communities. This stretch of roadway is known for accidents as well – would the tiny TnT be able to keep up with “always in a hur

UK Salary Data Shows Gender Gap at Triumph

The United Kingdom has a new law, requiring companies with 250 or more employees to report to the authorities the earnings of its workers, by gender. The topic has been a sticking point in the British news cycle right now, with woman across the company showing median earnings that are 12% lower than men, which is a sizable gap in income equality. Where does the British motorcycle industry falls into place in all this? Well as Visordown initially reported, that is more difficult to say, as it appears that only Triumph Motorcycles meets the reporting criteria, amongst motorcycle manufacturers. Technically, it is two brands that meet reporting criteria for gender pay gap, as Triumph Motorcycles Limited and Triumph Designs Limited split their duties for the British marque.

What Caused Jorge Lorenzo’s Crash at the Qatar GP?

After a poor start, which saw him drop from ninth on the grid to thirteenth at the end of the first lap, Jorge Lorenzo was making steady progress through the field at Qatar. His lap times were starting to come down to match, and on some laps even beat, the pace the leaders were running. As the halfway mark approached, and less than four seconds behind the leaders, Lorenzo started to believe he was capable of salvaging a decent result from a difficult start. That all ended on Lap 13. The Spaniard crashed out of the race at Turn 4, when his front brake failed and he had to drop the bike in the gravel. “I just felt that the level of the front brake was getting closer to my fingers and I didn’t have brake,” Lorenzo described the incident afterwards.

The Ducati Panigale V4 Looks Good Wearing Termignoni

For a long time, the name “Termignoni” was synonymous with “Ducati exhaust”, with the popular scarico-maker being a constant fixture in the Ducati Performance parts catalog. So prevalent was the brand, that if you see a turn-of-the-century (21st century, that is) Ducati clacking down the street with its dry clutch, chances are the exhaust you are also hearing was made by Termignoni. But that has changed in recent years, with Slovenian marque Akrapovič supplanting Termignoni in Ducati’s good graces. To find out why, all one had to do was examine the products themselves – where Termignoni’s pieces were poorly fabricated and over-priced, Akrapovič was infinitely better built and often cheaper.

Honda CBR1000RRW Debuts for Endurance Duty

What you are looking at here is the bike that Honda hopes will win the Suzuka 8-Hours endurance race this year. It is called the Honda CBR1000RRW. It is not all that different from the WorldSBK-spec model, the one that Leon Camier and Jake Gange are competing with currently (and that PJ Jacobsen is helping develop), save for some interesting changes. For starters, the Honda CBR1000RRW dumps its Cosworth boxes, and instead runs the Magneti Marelli electronics package that Jacobsen is using in WorldSBK. Also, there are some obvious bodywork changes, namely where the exposed front spars of the frame would be, which are now covered by a silver painted panel.Then of course, there are the mechanical changes for endurance duty, like quick-change wheel pieces and functional lights.

Honda CB300R Coming to USA with Retro-Modern Looks

One of the surprise pleasures at last year’s EICMA show was Honda’s family of “Neo-Sports Café” street bikes, which brought a retro-modern look to Big Red’s approach road bikes. While the new Honda CB1000R tickled our fancy the most, we were delighted to see that the theme extended all the way to the Japanese brand’s small-displacement platform, the Honda CB300R. An attractive and affordable entry-level bike, the Honda CB300R looks like it was designed in Europe, rather than Nippon, which is probably why the 286cc commuter is doing so well in the European market. Seeing that success, American Honda has confirmed the CB300R as an early 2019 model for the US market – available in July 2018.

Motorcycling’s April Fools Round-Up for 2018

Another year, and another April Fools Day is done and dusted. I am fairly certain that for journalists, April 1st is better than Christmas, as it marks the one day where media outlets make the news they wish they could report on daily. And as usual, the imaginations of the motorcycle media pool didn’t fail to disappoint. My colleague David Emmett had a nicely done story about the MotoGP World Championship. For my own part, I took advantage of the long-con approach, and fit a story into our ongoing series about the upcoming Suzuki Hayabusa, which seems to have no shortage of weekly rumors about this bike’s supposed features and technical specifications. How about from the rest of the industry though? In case you missed them, the highlights of April Fools Day are after the jump.

This Week’s Suzuki Hayabusa Rumor, Part 3

We know to expect a Suzuki Hayabusa reboot in the coming months, and in a way, that is all that we know. The iconic superbike is in its 20th year of production right now, and an all-new machine is set to take its place, for the 2019 model year. Will it be turbocharged? Will it have a larger displacement? How about a dual-clutch transmission? That remains to be seen. Safe bets are that the 2019 Suzuki Hayabusa will have updated electronics, likely powered by an inertial measurement unit (IMU). Euro4 emissions homologation is a must, and Suzuki will presumably be building the new Hayabusa with the Euro5 standard in mind as well. Beyond these givens though, it seems that every week there is a new rumor regarding the next Hayabusa generation, and this week is no different.

MotoGP Introducing “Transfer Window” for Rider Contracts

There has been a trend over the past decade for rider contract negotiations to get earlier and earlier. Where once, talks about new contracts would start sometime in June, and agreements finalized and signed during August, now, initial discussions start at the Valencia Grand Prix the year before a contract is due to end, and deals are signed in the first few races, or as in the past two contract cycles, before the season has even begun. The underlying causes for this trend are numerous, but at its heart, it comes down to the glut of talent that is in MotoGP these days, both in terms of riders and in terms of bikes. The best riders have more choice of competitive machinery, and there are more talented riders for the factories to choose from.

The sound of two-stroke race bikes will once again thunder through the streets on the Isle of Man, as Ian Lougher is set to race the Suter MMX 500 at this year’s Isle of Man TT.

The 576cc V4 two-stroke Suter has already made its debut during the TT, last racing during the 2016 edition of this iconic road race, though with lackluster results (121+ mph best lap) due to mechanical issues.

Hoping to right that wrong, Lougher will once again climb aboard the Suter MMX500, and no matter what the result sheets say, we are sure the fans along the Manx hedgerows will enjoy his effort.

Up-Close with the Suter MMX 500

07/10/2017 @ 9:55 am, by Jensen BeelerADD COMMENTS

By my nature, I am a critical person. This isn’t exactly a desirable personality trait, but it serves me well in my chosen profession. Accordingly, I rarely ever use words like “perfect” or “flawless” when describing something. It’s just not in my nature.

From my lens, there is always room for improvement. But, when it comes to seeing the Suter MMX 500 up-close and in person, I had to rethink my usual choice of words. I will sidestep superlatives and simply say that the Suter MMX 500 is a true rider’s motorcycle.

On the Suter MMX 500, there are no electronic rider aids, no ride-by-wire throttles, no kickstands, mirrors, or lights. There is nothing on this machine that doesn’t serve a purpose, and the only acceptable purpose is to go as fast as possible.

I am about to ruin your day, because I am going to show you something that you will want very badly, but can’t have. It is what happens when you have the best of both worlds. It is the two-wheeled version of having your cake and eating it too. 

This machine is called the Yamaprilia, and as the name implies, it is a mashup of the Yamaha RZ350 and the Aprilia RS250. Using the two-stroke, twin-cylinder engine from the RZ350, and the twin-spar aluminum chassis of the RS250, owner Gareth Evans is looking for the best of both worlds.

The build is an interesting one – and is featured by our friends at BikeEXIF – as it involves Evans fabricating more than a few parts himself – something that is easier to do when you have a background in mechanical engineering, like Evans does.

Fuel injection has finally come to the two-stroke market for production motorcycles, with KTM (and thus also Husqvarna) debuting two enduro machines with transfer port injection (TPI) on their single-cylinder smokers.

This has been a long time coming in the two-wheeled space, even though we have seen TPI and direct injection on other two-stroke vehicles, like snowmobiles and personal watercraft for quite some time now.

KTM is really the last manufacturer to support two-stroke motorcycles though, so any progress in this space is a welcomed breath of life for off-road riders. New technology truly could be the savior to two-stroke motorcycles, as emission standards continue to become more restricted with each passing year.

While the Japanese brands have focused their efforts on four-stroke motorcycles, KTM and Husqvarna are showing that there is still a market for these lightweight and efficient enduro models.

There is an Austrian boat-ton of high-resolution photos waiting for you after the jump. Like…a lot. Using the Erzberg mine as a back drop, these stunning shots will probably make you run out to your local KTM dealer. They certainly have us thinking. Enjoy!

Husqvarna Two-Strokes Get Fuel-Injection Too

04/04/2017 @ 3:14 pm, by Jensen Beeler9 COMMENTS

We shouldn’t be surprised to hear that Husqvarna will be following suit with its Austrian sibling, and adding fuel-injection to several of its two-strokes enduro motorcycle for the 2018 model year.

After a long history of rumors and development, KTM finally debuted fuel injection for a production two-stroke model just a few weeks ago, using the technology on two of its upcoming enduro models, the KTM 250 EXC TPI and KTM 300 EXC TPI.

Husqvarna will use the same technology for its own motorcycles in the same segments, announcing today the the all-new 2018 Husqvarna TE 250i and 2018 Husqvarna TE 300i enduro models with transfer port injection.

Two Enthusiasts Podcast #48 – Mechanical Masochism

03/30/2017 @ 11:25 am, by Jensen Beeler3 COMMENTS

In Episode 48 of the Two Enthusiasts Podcast, we didn’t set out to talk about all the weird technologies in the motorcycle industry, though our conversation certainly covered its fair share of them.

We start the show talking about the Vyrus 986 M2 supersport, which features a unique hub-center steering chassis. This leads us into a conversation about the supersport market, and the rumors that Suzuki is bringing out a new GSX-R750.

From there, Quentin breaks some news that a reliable source has told him that there will be a new Suzuki GSX-R600 for the 2019 model year, which goes against what had previously been rumored. We then finish up the Suzuki talk with a quick discussion about the Suzuki Hayabusa, and hyperbikes in general.

The show ends with us talking about KTM’s new fuel-injection for two-stroke dirt bikes, and what that means for that segment of the industry. Q also tries his best to explain how transfer port injection works, though we would recommend googling some visual adds when you get to that portion of the show.

A fun show, though we think you will also find it very insightful as well.

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!

KTM Debuts Fuel Injection for Two-Stroke Motorcycles

03/15/2017 @ 12:19 pm, by Jensen Beeler78 COMMENTS

The day has finally, come. The rumors can finally be put to rest. Fuel injection for production two-strokes is officially a thing, thanks to the clever minds at KTM.

The Austrian announced today that it will bring fuel injection technology (called Transfer Port Injection) to its 2018 enduro lineup, which will debut later this May.

Two KTM models will have the new technology, the KTM 250 EXC TPI and KTM 300 EXC TPI, and they will be coming to the global market. For the USA and Canada, a third model will come to market as well, the KTM 250 XC-W TPI.

Fuel injection for two-strokes promises better fuel consumption, and it means that riders no longer have to pre-mix their fuel. KTM says that its transfer port injection technology provides a whole new experience for riding a two-stroke motorcycle, with better power and rideability.

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.

2016-Husqvarna-TE-250

It looks like Europe’s new Euro4 emissions standard has claimed its first victim (if you don’t count the exhaust pipe on the Ducati 959 Panigale), as neither KTM nor Husqvarna will be producing their 125cc two-stroke enduro models for 2017, and the foreseeable future afterwards.

The move is a euros and cents decision, and a slightly complicated one at that, but it boils down to the fact that making the small-displacement smokers meet the more stringent Euro4 emissions requirements was financially prohibitive.

Suter-MMX-500-Isle-of-Man-TT

Two-stroke fans were stoked to hear of Suter Racing building a 500GP-styled superbike smoker, the Suter MMX 500. The 576cc, V4, two-stroke machine promises superbike power coupled to a GP-level punching weight, 195hp and 280 lbs respectively, with modern suspension and chassis design.

Only 99 specimens of the Suter MMX 500 will be produced though, each costing CHF 120,000 – roughly $125,000 or €109,000. And now, one of those machines has been tapped for racing duty, as Suter will be competing in the 2016 Isle of Man TT.

Therefore, expect to see the Suter MMX 500 racing in the RST Superbike and PokerStars Senior TT races, with Ian Lougher behind the handlebars.
