Metzeler Brings Out 18″ Tires for Classic Racers

Vintage racers know all to well the difficulty there can be when it comes to finding appropriate tires for the race track, as the odd rim sizes of classic motorcycles are often outside the sizing parameters of good modern sticky tires. This leaves many racers using street-focused tires for their racing needs, but that could all come to an end, as Metzeler is expanding its Racetec RR Range to include 18-inch wheel sizes. Going forward from today’s announcement, the Metzeler Racetec RR DOT race tire will come in the company’s K1 compound (Metzeler’s softest compound), in the following sizes: 110/80-ZR18 (58W) front, and 150/65-ZR18(69W) & 160/60-ZR18 (70W) rear tires.

Sweet Jesus, Investors Revive Skully Helmet Project

For reasons beyond our imagination and comprehension, the failed business experiment that was the Skully AR-1 helmet has been revived by new investors. Sending out a blast to the “Skully Nation” email list, the brand’s new owners Ivan and Rafael Contreras, have announced their plans to revive this seemingly dead project. One can barely fathom why someone would want to continue a project that so obviously was doomed to its own failure, and that also so grossly betrayed the goodwill of the motorcycle community; and yet, here we are, with Skully Technologies taking over where Skully, Inc. left off. The presumption of this news is that the new management hopes to bring the AR-1 helmet, with its heads-up display technology, to market.

Nike Makes Air Force 1 Shoe for 12 O’Clock Boys

The Nike Air Force 1 shoe is perhaps the most iconic piece of footwear ever created. It spurred an entire industry of sneakerheads – people who collect and trade shoes – and the Nike AF1 is one of the most collectible items for this genre of collector. So, it’s not surprising that there is industry buzz about a new Nike Air Force 1 being created. With each release, Nike has kept AF1 brand in line with its urban roots, where playing basketball on the street gave rise to young kids who would dream of following their heroes, like Michael Jordan, onto the courts of the NBA. Now having more of a cult following, Nike has been branching out with its AF1 offerings, and last month the sport brand debuted a special AF1, which pays tribute to Baltimore’s 12 O’Clock Boys.

Unions End Partnership Agreement with Harley-Davidson

Two labor unions have ended a partnership agreement with Harley-Davidson, citing differences with how the Bar & Shield brand handles staffing issues at its factories (Harley has been accused of replacing hourly union workers with temporary seasonal workers). The move comes after a meeting on Monday, which saw leaders from the International Association of Machinists & Aerospace Workers (IAM), United Steelworkers (USW), and Harley-Davidson President & CEO Matt Levatich unable to agree on how to handle staffing issues going forward. While the disagreement ends an accord that has existed between the unions and Harley-Davidson for the past two decades, it does not affect the collective bargaining agreement that the unions have with Harley-Davidson, which has been incorrectly reported elsewhere.

US House of Representatives Passes Self-Driving Car Bill

Say what you will about American politics, but the US House of Representatives has passed the “SELF-DRIVE Act” (H.R. 3388) – a bipartisan bill that would open up autonomous vehicle regulation for manufacturers. The big advantage of the SELF-DRIVE Act is that it would supersede the varying and ad hoc state rules that manufacturers must currently adhere to while developing their autonomous platforms. The bill would also do away with some safety standards put in place for vehicles with drivers, such as where the steering wheel and foot pedals must be located. Lastly, the SELF-DRIVE Act would require the Department of Transportation (DOT) to research and develop a way of conveying to consumers the level of automation a vehicle possesses.

Is the MV Agusta Brutale 800 the Best Bike on the Market?

In early 2016, I was fortunate enough to ride the revamped and Euro4 version of the MV Agusta Brutale 800. On paper, the Brutale 800 lost power and gained weight, but the reality is that MV Agusta improved upon already one of its best-selling machines, in subtle and clever ways. Now a year-and-a-half later, the 2017 MV Agusta Brutale 800 is finally available in the United States, and I have been reunited with one of the best street bikes on the market. Spending almost all of last month with this motorcycle again, it is clear that not much has changed from a rider’s perspective, though internally improvements have been made to some of the weaker elements of the design, like the sprag clutch and valve train. While not much has changed with this year’s edition of the MV Agusta Brutale 800, I am mostly fine with that.

Lin Jarvis Talks Rossi’s Injury, Replacement, & Training

What happened when Valentino Rossi crashed? How serious is his injury? When will he be back? Who will replace Rossi, if he doesn’t return at Aragon? And what does Yamaha think of Rossi’s training methods? Yamaha boss Lin Jarvis spoke to a small group of journalists at Misano on Saturday morning, to answer these questions and much more. Jarvis knew about the accident very shortly after it had happened. “I knew before he got to the hospital,” Jarvis told us. “Albi [Tebaldi] called Maio Meregalli as soon as he got the news that Vale was on the way to the hospital. Maio called me straight away.” The good news was that Rossi’s injury was not as bad as the last time he broke his leg, at Mugello in 2010. “It’s much less serious,” Jarvis told us, “but probably just as irritating.

Aprilia Debuts Augmented Reality Helmet for MotoGP

While the launch of the Ducati’s Desmosedici Stradale V4 engine and leaked photos of the Ducati Panigale V4 dominated the news on Thursday, Aprilia Racing was quietly changing the sport of motorcycle racing, as it debuted an augmented reality helmet that its mechanics will wear in MotoGP. Aprilia has partnered with DAQRI and Realmore to make the augmented reality helmet come to fruition – DARQI is making the hardware, while Realmore is responsible for the software. As followers of augmented reality (AR) tech may already have guessed, Aprilia Racing’s AR helmet will allow its mechanics to visualize and share information, overlaid on what is occurring in the pit box. Aprilia Racing sees two major scenarios where using augmented reality could be of benefit.

More Leaked Photos of the 2018 Ducati Panigale V4

Apparently today is Ducati Day, as news continues to come from Italy about the Ducati Panigale V4 and its Desmosedici Stradale engine. Ducati has already spilled the beans on the new 210hp V4 engine it has been developing for its next superbike, but now we also get more spy photos of the Panigale V4 that will carry it. These latest spy photos show quite clearly the 2018 Ducati Panigale V4 that will debut later this November, at the EICMA show in Milan. Ducati CEO Claudio Domenicali confirmed the Panigale V4 name today, and for our A&R Pro members, we have gone into a lengthy analysis as to why Ducati is choosing to keep the styling and name of this machine so similar to the previous model.

Ducati Reveals the 210hp Desmosedici Stradale Engine

Hello and welcome to a new era of Ducati motorcycles, which is starting with a very special engine. Named the Desmosedici Stradale, this road-going version of the company’s MotoGP power plant is what is going to power Ducati’s next superbike, the Ducati Panigale V4. Debuting today in Misano, at a special event ahead of the San Marino GP, the mystery around the Desmosedici Stradale engine has finally be revealed, to the tune of 210hp (@ 13,000 rpm) and 88.5 lbs•ft of torque (@ 12,250 rpm). Dropping details on the 90° V4 engine with desmodromic valves, we now know that Ducati will continue to play the displacement game with its superbike, as the street version of the Panigale V4 coming with a 1,103cc displacement.

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.

Beauty Is Wedging an RZ350 Motor into an RS250 Frame

06/20/2017 @ 12:37 pm, by Jensen BeelerComments Off on Beauty Is Wedging an RZ350 Motor into an RS250 Frame

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.

Here Is KTM’s Fuel Injected Two-Stroke Motorcycle

05/16/2017 @ 4:03 pm, by Jensen BeelerComments Off on Here Is KTM’s Fuel Injected Two-Stroke Motorcycle

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.

two-stroke-exhaust-header

Do you ever go for a ride in the woods, come home smelling like pre-mix, only to lose that sweet scent once you finally take a shower? Has the move to four-stroke machinery greatly reduced your ability to woo a worthy partner to make “brap brap” noises with throughout the night?

Never fear dear reader, we understand your plight. Behold, 2 Stroke – a manly cologne that has been scented from the smell of two-stroke machinery, with hints of pine and spruce. Your braplife needs this.
