More on the New Honda VFR
Our cousins in the UK at Motorcycle news report that the new Honda V-4 bike has a lot more to it that previously thought.Â There’s apparently a lot of innovation in this new bike.
First up is the variable cylinder use.Â Instead of running in a V-4 and V-Twin profiles, the engine can also run as a triple.Â The ECU will select the use of two, three or four cylinders based on engine demand, and throttle input. So, the rider will get smoother transitions between the different cylinder use profiles, which should translate out to a broader range of usable power for the rider.
When in two or three-cylinder mode, instead of the non-working pistons being air springs, they will actually be running in vacuum. So, instead of losing power on the upstroke of the dead cylinder, the empty cylinder will actually serve as a vacuum assist for expanding the active cylinder during its power stroke. So, on net, you get a power increase for the working cylinders.
In addition, the engine, being a V-4, will inherently have the same crossplane effect that Yamaha has used to such rave reviews in its R1 sportbike.
Moving from the engine to the gearbox, the new bike will utilize a double clutch system, similar to the ones used by Porsche.Â The rider will be able to select three modes: Drive, Manual and Sport.
Drive mode will put the bike in charge of all the shifting.Â It’s essentially an automatic transmission for the motorcycle, and the emphasis will be on economy, with the ECU doing short-shifting to keep the bike in two- or three-cylinder mode.
Manual mode will put the rider in charge of shifting, but the twin-clutch set up will be used to anticipate the next gear change, so the rider can shift as smoothly and quickly as a race bike with a quickshifter.
Sport mode will once again put the ECU in charge of shifting.Â But this mode is designed to run to the redline in every gear, giving you peak HP–which is rumored to approach 200HP–and torque as much as possible, and allowing you to concentrate on steering the bike, cranking the throttle, and moving your butt cheeks back and forth to hang off as necessary.
And this new bike is just the beginning.Â Apparently, Honda has plans to build a whole new series of bikes based on this technology.Â This first bike will replace the VFR and, apparently, the ST1300/Pan-European.Â But beyond that, Honda is going to give us lots of biking goodness based on the new V-4 platform.
The only remaining question is whether or not we will see this bike in the 2010 model year or not.Â If we are, we’ll probably learn about it in the next 60 days.Â If it performs as Honda expects, then something like like this has the potential to be a game-changer in terms of what a rider should expect from a motorcycle.
I am really interested in taking a look at this bike.
