The heat expansion could cause potential failure of the headlight, which would reduce visibility of the motorcycle to oncoming traffic and increasing the risk of a crash.
Time-lapse build videos are always fascinating, and since it’s well into Friday afternoon now, we are of course padding the post count here at A&R with this installment from the Monster Energy Graves Yamaha AMA Pro Superbike team.
In five hours the Graves crew built this Yamaha YZF-R1 race bike from the ground up, but you can see them put it together in just over a minute’s time. If you look close enough, you can even spot the reasons why Josh Herrin & Josh Hayes are running away with the 2013 AMA Pro National Guard Superbike Championship.
Reading through the comments on the Attack Kawasaki CRT bike and its new crossplane crank, it is clear that the concept of what makes an engine have a crossplane configuration, like the one found in the current Yamaha YZF-R1, is still a bit of an enigma for some motorcyclists.
Referring to the way a crankshaft is built, with the four crank pinks at 90° from each other, an inline-four engine with a crossplane configuration fires its four pistons in a different order, and with different intervals between ignitions, than a normal engine with 180° pin positions.
A subject we’ll broach in greater detail at a later time, we thought this video from Yamaha would at least highlight some of the major differences and reasons for using a crossplane crank in a sport bike motor. Enjoy it after the jump.
Debuting a “crossplane” three-cylinder engine at the INTERMOT show, Yamaha has gotten the word out that it intends on making more inspiring motorcycles, and part of that plan includes the use of triples in its upcoming bikes. Knowing that at least one, if not several future Yamahas will use the hinted-at three-cylinder lump, the Brits over at Visordown have gotten word from their sources within Yamaha Japan that in the coming future, the Yamaha YZF-R6 & Yamaha YZF-R1 will be two of the bikes to receive such modifications.
Debuting a three-cylinder concept at the INTERMOT show in Cologne, Yamaha is teasing the hypothesis of a tuning-fork brand triple with a crossplane crankshaft.
A technology that was developed in MotoGP for Yamaha YZR-M1, and then handed down to the Yamaha YZF-R1 in 2009, the unique qualities of the crossplane inline-four cylinder motor has been a key component to Yamaha’s potent, yet ridable machines.
Taking that same idea, and then applying it to a three-cylinder engine, Yamaha hopes to create a new motor that will appeal to street riders.
Debuted at the San Marino GP, Yamaha’s new Race-Blu livery is set to black & blue the European market when it hits dealers this October (December for the R125). While we still get the tasty Graves Yamaha inspired Team Yamaha Blue/White, you might be longing for the matte grey and vivid primary blue color scheme that Jorge Lorenzo rode to victory at Misano this past weekend.
Coming to the 2013 Yamaha YZF-R1, 2013 Yamaha YZF-R6, & 2013 Yamaha YZF-R125, the Race-Blu livery is very fetching, so it is a bit of a shame that we won’t be seeing it here in the USA. Maybe if we Americans hold our breath until we go blue in the face, Yamaha USA may consider it as a mid-model year option (not likely).
Don’t feel blue though, we can still live vicariously through our European brethren. More photos of how Yamaha Blu itself after the jump. There’s gotta be a better way to say that.
Yamaha Racing has debuted its “Race-Blu” livery at Misano today. The work of Aldo Drudi (of Valentino Rossi helmet fame), the blue and matte grey paint scheme is the same special color schemes that will be available on the Yamaha YZF-R1, YZF-R6, and YZF-R125 bikes for 2013, seemingly everywhere except the United States.
Yamaha says the livery is a throw-back to its historic racing blue colors of the 1980′s. Factory riders Jorge Lorenzo and Ben Spies will also wear special Race-Blu leathers for the races at Misano and Aragon. Will the special livery prove to be as lucky as the Red/White 50th Anniversary livery? Only time will tell.
Unless Yamaha has some Steve Jobs-esque “one more thing” trick up its sleeve for its 2013 sport bike line, fans of the tuning fork brand should prepare themselves for a color and graphics package-only update to the 2013 Yamaha YZF-R1 & 2013 Yamaha YZF-R6.
Simply stating that the “2013 YZF-R1 and YZF-R6 come back in a variety of new and exciting colors,” Yamaha’s press release is void of any mentioning of an update to the R1 or R6′s electronics package or other technical add-ons, let alone any revision to the major components of the machines.
With Honda already showing us its re-styled Honda CBR1000RR for 2012, and Kawasaki and Suzuki expected to stay the course with their liter-bike models, it would seem the only guaranteed change in sport bike offerings from the Big 4 for 2013 is the revamped Kawasaki Ninja ZX-6R, which sees the same chassis outfitted with a 636cc motor and new bodywork. Humpf.
What is perhaps more interesting is that there appears to be no movement from Yamaha or Suzuki in bringing a 250cc class sport bike to the American market — thus leaving all the quarter-liter fun to Honda and Kawasaki. Photos of the 2013 Yamaha YZF-R1 are after the jump.
Ian Hutchinson may not be a household name here in the United States, but over on the Isle of Man, “Hutchy” is a pretty big deal. Winning five solo-class races in the 2010 season, the English rider’s hot-streak was cut short after a tragic closed circuit racing accident, which saw him sidelined for the 2011 TT fortnight. Suffering another leg injury going into the 2012 racing season, Hutchinson was still physically not 100% as he headed to the TT, with the Swan Racing Team making obvious adjustments to his Yamaha YZF-R1 to accommodate Hutchy’s injured leg.
While Hutchinson would ride through the pain, he was noticeably off the pace during this last TT meeting. While a large component of those results are surely products of his physical state, where were compound by the fact that his practice and racing schedule has been truncated, many also wondered about Hutchinson’s mental state as well. Twice beaten, once shy, one Swan team member explained to me that when you looked into the his eyes as he got on board the bike, there was something there that didn’t exist before in Hutchy’s eyes. “Fear?” I asked. The team member wouldn’t comment further.
For some time now, Yamaha Japan has had some fun downloadable paper craft sheets that make a variety of paper art motorcycles (if you haven’t made a paper YZR-M1 yet, you are really not living life). Taking that thought a step further, Jack Chen from Australia has made a scale 2007 Yamaha YZF-R1 out of cardboard.
Roughly 60% the size of the genuine road-going version, Chen used Yamaha’s sheets as the basis for his masterpiece, and then super-sized the proportions. Skill, patience, and scissor control…you sir are a cardboard motorcycle Jedi, and we salute you. Photos after the jump.
