The Honda RC212Vs are fast this year, there’s no denying the point. The top four overall testing times at the second Sepang test were each slotted to one of the four factory Honda riders. Accused of developing and using a dual-clutch transmission (DCT) by the Italian press, Honda has come under scrutiny for using a technology that is banned in GP racing. While not using a DCT, Honda says it has developed a new transmission that is in compliance with MotoGP regulations, and produces extremely quick gear changes, like a dual-clutch transmission.
Perhaps bigger news than the bike itself is the Honda VFR1200F’s much-anticipated dual-clutch transmission (DCT) model. What Honda has developed for the sport bike world is an automatic shifting technology to enhance the rider’s experience. Automatic transmissions are a rare breed in motorcycling, and we have no doubt that some of you out there may be asking: Isn’t part of being on the road and on the bike, about feeling personal freedom? Or mastering your machine with skill and control? As kids in high school didn’t we make fun of our friend that couldn’t drive a stick? Is DCT an upgrade or a substitution? Well folks, that was the other reason Asphalt & Rubber got to test ride the new VFR1200F, and we put the DCT through its paces.
Visordown is reporting that Yamaha is planning an electronically controlled dual-clutch transmission for a future version of its YZF-R1 superbike. Taking a page from the Honda VFR1200F’s DCT setup (check for our ride report on this in the next few days), Yamaha is looking to implement a simpler DCT system than the one found on the Honda VFR, with a clutch on either side of the motorcycle gearbox.
Yamaha’s DCT is different from the Honda unit, which employs an input shaft the runs through the other input shaft, and has the clutches all on one side of the motor. Instead of this all-in-one arrangement, Yamaha is using a split input shaft that’s half the normal length, with each half attached to an opposing clutch. The overall affect is a much simpler arrangement, but is not as compact or light as the Honda DCT.
Visordown is reporting that Honda has filed patents in Japan that would allow the motorcycle manufacturer to port their dual-clutch transmission, a la VFR1200F, over to multiple platforms in the Honda line, including the Honda CBR1000RR. The patents reportedly center-around reducing the cost to implement the DCT into other motorcycle models by simplifying the electronics and sensors that go into the transmission, and removing expensive components of the existing DCT transmission.
As we edged closer to the official unveiling of the 2010 Honda VFR1200F, more details about the bike are starting to emerge. This latest detail confirms the rumor that the new VFR would be fitted with a dual-clutch transmission, making it the first motorcycle to incorporate such a gearbox design.
Similar to the DSG clutches found on Audi and Volkswagon cars, the Honda dual-clutch transmission will incorporate two clutches that alternate what gears they actuate, making for rapid shift times. Click past the break for pictures, video, and more on the VFR1200 transmission.
