Photos from 250+ Feet up COTA’s Petrolsaurus Rex

Standing 251 feet above Turns 16, 17, & 18, the COTA observation tower provides a bird’s eye view of just about every tun on the circuit, if you can stomach its subtle sway in the wind and clear-glass floor at the precipice. Officially called by COTA as the “Observation Tower” – it really needs a better name for casual conversation. We’ve heard COTA Cobra used a few times with some lovely alliteration, but the structure has always struck us as less snake-like, and more like a big dinosaur — we’re going to use the name “Petrolsaurus Rex” until I hear something better, or COTA sends me a cease and desist order. I climbed to the top of Petrolsaurus Rex (read: took the elevator) during the MotoGP Warm-Up session, and snapped a few photos in the process. Enjoy!

MV Agusta F3 800 Ago Now Officially Debuts

We already announced the bike last November, and brought you a bevy of hi-res images of the special edition machine. Although now that we think of it, MV Agusta never released anything on this Giacomo Agostini tribute motorcycle — better late than never, right? Back at the EICMA show launch, where the MV Agusta F3 800 Ago was first shown to the public (and Agostini himself), the Varese brand promised us two additional motorcycle launches in early 2014. MV Agsuta made good on half that promise with the Dragster 800 model, hopefully this Ago special edition isn’t the other half of that statement, and MV Agusta still has something waiting in the wings. That being said, the Tricolore & Gold paint scheme is gorgeous, and looks even better in person.

Isle of Man TT Gets TV Deal for Australia & USA

Want to watch the Isle of Man TT from the comfort of your non-British TV, but haven’t been able to in the past? A new TV from the Isle of Man’s Department of Economic Development will do just that. Inking a new TV contract with North One TV, the Isle of Man TT will be televised in the American, Australian, and of course British markets, making it easier than ever to watch the iconic road race. With a five-year contract with the Velocity Channel in the US, the American cable channel will show seven one-hour race shows. Each segment will air within 24hrs of each race, and be tailored for the American market.

Castiglioni Denies Fiat Buyout of MV Agusta Is in the Works

After reporting 22% growth in Q1 2014, Giovanni Castiglioni had some closing words about the rumors that Fiat could acquire MV Agusta — a popular rumor that has been swirling around in the press the last two months. Denying outright that MV Agusta had, or was in, talks with the Fiat-Chrysler group about an acquisition (some reports linked even MV Agusta to being bought by Fiat-owned Ferrari), Castiglioni said the Italian company solely was focused on building growth, and building motorcycles. “Moreover, I’d like to take this opportunity to deny rumours circulated by the media over the last few days concerning supposed negotiations vis-à-vis the sale of a share of MV Agusta to the Fiat-Chrysler Group,” said Giovanni Castiglioni, the President and CEO of MV Agusta.

A 2WD Hybrid-Electric Motorcycle for the US Military?

In the coming years, US special forces may be riding a tw0-wheel drive, hybrid-electric, multi-fuel motorcycle co-developed by BRD Motorcycles and Logos Technologies. Helping make this project possible is a Small Business Innovation Research grant from DARPA. The goal is to make a single-track vehicle for US expeditionary and special forces that will be nearly silent in operation, yet also capable of traveling long distances. Details on the proposed machine are light, of course, but it sounds like the 2WD dirt bike will be based off the BRD RedShift MX (shown above), and use an electric drivetrain, as well as a multi-fuel internal combustion engine to achieve its goals.

Colin Edwards Will Retire from Racing after 2014 Season

Announcing his decision during the pre-event press conference for the Red Bull Grand Prix of the Americas, Colin Edwards told the assembled press that 2014 would be the Texan’s last season racing a motorcycle. Citing a lack of improvement on his performance in pre-season testing and at the Qatar GP, Edwards decision perhaps answers the lingering question in the paddock of when the American rider would hang-up his spurs after an illustrious career in AMA, WSBK and MotoGP. Talking about his inability to come to terms with the Forward Yamaha, which Aleix Espargaro was able to take to the front of the pack in Qatar, Edwards was at a loss when it came to understanding the Open Class machine and his lack of results.

MSF Updates Its Basic RiderCourse Curriculum

It is no surprise that statistics from the NHTSA show that motorcycle accidents and injuries are on the rise. According to the 2012 Motor Vehicle Crash report published by the NHTSA, motorcycle fatalities for that year rose to 4,957, up seven percent from 2011, while injuries increased 15% to 93,000. While the NHTSA statistics are misleading because the motorcycle category includes mopeds, scooters, three-wheelers, pocket bikes, mini bikes, and off-road vehicles, new riders need every advantage they can afford. The Motorcycle Safety Foundation has taken notice of these statistics and has revised the curriculum for its Basic RiderCourse to include a new Basic eCourse, which students will take prior to in-person instruction.

Yamaha Trademarks “R1S” & “R1M” at USPTO – “YZF-R1M” Trademarked Abroad – But Why?

Are new Yamaha YZF-R1 models coming down the pipe? That’s the question being asked after trademark filings in the US and abroad tipped off Yamaha Motor’s intention to use “R1S”, “R1M”, and “YZF-R1M” for motorcycle, scooter, and three-wheeled purposes. The filings are being taken as hints towards a possible multiple trim levels of the Yamaha YZF-R1 superbike, with the “S” and “M” designations being different spec machines than the current base model. The “S” nomenclature is a popular one in the two and four-wheeled world, though “M” would certainly be a novel designation, outside of say…BMW.

Bell & COTA Create Texas-Themed Limited-Edition Helmet

Continuing its theme of making limited-edition helmets for premier-class US rounds, Bell Helmets has teamed up with the Circuit of the Americas and Chris Wood, of Airtrix, to create a Texas-themed Bell Star Carbon helmet, just in time for COTA’s MotoGP race next weekend. Available only until April 13th, the Bell/COTA helmet features a red, white, and blue flag motif on the front, with both the American and State of Texas flags visible, which then wrap around the rear to merge with a hardwood design, reminiscent of the floorboards in a Western saloon. The helmet is also crowned with a Longhorn cattle skull, which adds to the Texan motif. The specially designed helmet also features a horseshoe, the COTA logo, and the 2014 Red Bull MotoGP of The Americas logo.

Aprilia Mounting a Return to MotoGP in 2016

Towards the end of the 800cc era, MotoGP looked to be in dire condition. Grids were dwindling, factories were reducing their participation, and teams were in difficult financial straits indeed. By the end of 2011, there were just 17 full time entries, Suzuki was down to a single rider, and were about to pull out entirely for 2012. How different the situation looks today. In a recent interview with the official MotoGP.com website, Aprilia Corse’s new boss Romano Albesiano gave a brief outline of their plans. The Italian factory will continue to work with the IODA Racing team for 2014 to collect data on the electronics and tires, which they will use as input on an entirely new project being worked on for 2016.

Ilmor Engineering Builds a Five-Stroke Motor

Ilmor Engineering Builds a Five Stroke Motor ilmor 560x420

Motor manufacturer and tuner, Ilmor Engineering, has branched out from its Indy Car, Formula One, NASCAR, and MotoGP duties, and produced what they call a five-stroke motor. With dual camshafts and an asymetrical three-cylinder configuration, the Ilmor is more than intriguing with its design, and promises to bring real benefits both to the race track, and to road-use. Most notably is a 10% increased fuel efficiency, and 20% weight reduction in power-plant weight.

With its 700cc, turbocharged, prototype motor, Ilmor is able to extract 130hp and 122 lbs•ft of torque. To achieve this, the motor employs two overhead camshafts. One is a “high pressure” camshaft, which turns at half the crank speed, while the other shaft is a “low pressure” camshaft, which turns at the same speed as the crankshaft.

The high pressure shaft powers the two outside cylinders, which operate like a normal four-stroke motor, while the low pressure shaft powers the larger center cylinder, which gathers exhaust flow from the other two cylinders. This larger cylinder can also adjust its expansion and compression strokes, allowing it to be tuned for specific applications.

Ilmor hopes that this new design will allow its motor to be more fuel efficient over normal four-stroke gas motors. With no exotic materials or elaborate construction processes, the design should be fairly simple to implement in a variety of applications. Of course the most relevant to our concerns is for motorcycle racing and production. Ilmor has tried on several occasions to join the MotoGP ranks, and with fuel consumption a fairly large concern with the current fuel tank restrictions, Ilmor may have a nice competitive advantage brewing here. They will of course have to overcome the fact their design uses forced induction, but anything could happen with future regulations.

    This is one of the reasons I’d love to see a more open-style MotoGP series, with pretty much just an energy limit, an emissions limit, a min. weight limit, and spec tires. Allow unlimited engine displacement and unlimited engine types, loosen up the bodywork regs some…and let the manufacturers and teams have at it. It would be really cool to see engine technologies like this and other non-4-cylinder 4-stroke 800cc powerplants produced specifically for MotoGP machines!

    5ストロークエンジン???

    While this looks like a clever way to increase efficiency and its convenient how every time one of the outside cylinders is on an exhaust stroke the central cylinder will be on a down stroke salvaging waste heat for extra power, almost exactly this setup has been used to increase the efficiency of steam engines for centuries (see Compound steam engine). Does the 700cc figure include the central second stage cylinder or only the two outer cylinders I wonder? While I could see fuel efficiency increasing from this design I’d be surprised if power/weight ratio wasn’t worse than conventional designs (hence the turbocharger in order to get the 700cc engine to produce the same power 600cc Supersport bikes are making now).

    I’m also curious about how the reduced exhaust temperatures from the greater exhaust expansion affect emissions control equipment.

    I do love how the central cylinder is 180degrees apart from the outer cylinders and is larger. If the central cylinder is exactly as heavy as the sum of the outer cylinders this engine should balance like an inline4 and not need counterbalancing. Would be cool to see a more conventional I3 engine with a larger central cylinder take advantage of that.

  5. lago says:

    Upon closer inspection the engine appears to have 2 valve/cylinder on its active cylinders. The central cylinder looks to have a single intake valve for each cylinder that feeds it and 2 exhaust valves. Might a later version have 3 camshafts, 2 high pressure and 1 low pressure, to help it breathe? I could really see an engine with this technology succeed in high gas mileage, hybrid cars, or even compete with hybrid technology in truck engines but race bikes don’t seem like the proper place to implement it. A truck with the extra weight capacity to not be impaired by the weight of the second stage cylinders on the other hand might be highly successful.

    How is the cam angle timing?
