Like the standard transmission...
Like the standard transmission model we tested, the rear shock features a remote spring preload adjuster. This version was a little easier to turn, but with long throws before each click
The differences between the standard transmission and the DCT model are even more pronounced when pushing the limits of what the bike is meant for. Because the "dual" in dual clutch transmission is really two halves of a single clutch (which is explained further in the accompanying sidebar), their overall strength is reduced. In order to quell the 142 horsepower and 81.4 ft-lb of torque during hard launches, the ECU will pull back power so as to not destroy the clutch. Full power is then restored once road and engine speed are deemed to be at a level the clutch can handle. This is readily apparent in the quarter-mile times between the standard and DCT models. The latter's 11.67 seconds corrected time compared to the 10.23 seconds for the former illustrate the disparity.
While the quarter-mile time is slightly surprising, we didn't think the roll-on numbers would be much different than the standard model since the clutches wouldn't receive the same stress. Again, the disparity was noticeable. A 0.5 second slower 60-80mph time (3.61 vs. 3.14) and a 0.7 second slower 80-100mph (4.27 vs. 3.50) were both larger gaps than we expected. For reasons we can't explain, Honda chose to gear the DCT model differently than the standard model. Overall gearing is slightly shorter, while internally the first three gears are also tweaked.
Showa suspension components...
Showa suspension components may not be top shelf, but they still impressed our testers. Damping rates were on the soft side, but still provided a firm ride in the twisties. Six-piston Nissin calipers clamping 320mm discs brought the VFR to a stop quickly with linear feel at the lever despite the linked braking. Dunlop Roadsmart tires heat up quickly and provide excellent grip and neutral steering for this heavy machine.
These numbers may be a little strange, but in the grand picture, neither transmission option on the VFR detracts from the riding experience. But there's more to the VFR than just the transmission. It's actually quite the overall performer as well. Forget the fact that it's intended as a sport-touring rig, the bike handles surprisingly well despite its rather simplistic Showa fork and shock, both adjustable only for preload and rebound. Stopping duties are by way of six-piston Nissin calipers and 320mm discs in the front, with a single 276mm disc in the rear and a twin-piston caliper. Honda's linked ABS (whereby only one set of pistons in one front caliper is activated when the rear brake is applied) is standard and works seamlessly without the usual pulsing on other ABS systems. Without having to worry about rev matching during downshifts, the DCT actually allows the rider to focus on other aspects of riding while the downshifts are perfectly executed each time. Unfortunately, one will also have to focus on where the next fuel station is; we averaged about 35 mpg of combined city and highway driving, and the 4.9 gallon tank doesn't provide much in terms of range.
Strangely, we weren't able...
Strangely, we weren't able to secure dyno numbers for our DCT test unit. Not because we were lazy, but because our bike refused to spin the drum when placed into gear. Apparently, the ECU senses a fault if the front wheel isn't spinning and won't let it shift out of first gear, even in full manual mode. Could the VFR feature some kind of traction control? Honda replied back with vague answers, so until we can get solid numbers we'll refer to the dyno graph from our standard transmission version.
What about slow speed maneuvers you ask? No problem. Unlike other clutchless motorcycles, the VFR can in fact execute a normal U-turn. With some slight rear brake modulation, outside peg weighting and gentle throttle application (similar to fanning the clutch on a regular motorcycle) the bike will turn around just like anything else.
